While he went on his way, I was left staring at this little box in complete disbelief that there was a 10\u20196 x 32.5 \u201c iSUP in there. <\/p>\n<p>Despite my initial doubt, the Blackfin CX Ultra <em>was<\/em> in that tiny box though, along with a string of other accessories that all pack away to fit into a roughly 2\u2019 x 1\u2019 SUP bag (about the size of a small carry-on suitcase). It can fit in the corner of a closet, in between the backseat of a car, and is light enough to be brought through an airport. In other words, the Ultra line solved all of our spacial problems in one fell swoop.<\/p>\n<p>While this new development was super exciting, I am stubborn at my core and tried not to let the storage component alone sway me on iROCKER\u2019s compact boards. I grew up on hard boards, and have consequently become a bit of a stickler when it comes to performance. And though I knew these boards had the potential to become one of our top recommendations to our readers, I wasn\u2019t about to let them have it easy. Rest assured, I put the entire Ultra series, especially the higher-end Blackfin CX Ultra, through the ringer to test for stability, maneuverability, speed, tracking, construction quality, and plain old aesthetics. <\/p>\n<p>I won\u2019t leave you hanging; the Blackfin CX Ultra (and frankly, the entire Ultra line) exceeded most of my expectations. At 10\u20196 long, 32.5\u201d wide, and equipped with a newly designed twin fin set-up, the CX Ultra is the sportiest, most agile and performance-focused SUP in iROCKER\u2019s Blackfin Series. Even still, it displays an accommodating level of stability without losing out on speed or tracking, and has achieved a standard of rigidity that surpasses even their heavier built SUPs while remaining just 19.8 lbs. <\/p>\n<p>The Blackfin CX Ultra has successfully intertwined lightweight, stiffness, and performance to manifest into this impressively compact board. As the final cherry on top though, the Ultra line is accompanied by one of the highest value SUP kits we\u2019ve seen to date, and includes their iROCKER 12V Electric pump, a multi-year placeholder on our list of Best Electric Pumps. <\/p>\n<p>We think the Blackfin CX Ultra  would be great for paddlers who:<\/p>\n<ul>\n<li>Want a truly compact inflatable SUP that can accompany them on tons of adventures, whether it be hikes up into mountain lakes or a flight to a tropical destination<\/li>\n<li>Value performance above all else, and aren\u2019t willing to compromise between board weight and rigidity<\/li>\n<li>Need a high quality kit to compliment the SUP<\/li>\n<li>Want an all-around with above average tracking and speed capabilities without losing out on maneuverability<\/li>\n<li>Are primarily paddling in flat water with chop or mild ocean waves<\/li>\n<\/ul>\n<figure id=\"attachment_10683\" aria-describedby=\"caption-attachment-10683\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4.jpg\" alt=\"Blackfin Ultra CX\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-13095\" srcset=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4.jpg 1200w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4-300x200.jpg 300w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4-1024x683.jpg 1024w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4-768x512.jpg 768w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-4-50x33.jpg 50w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-10683\" class=\"wp-caption-text\"><em><\/em><\/figcaption><\/figure>\n<h2>Blackfin CX Ultra : Spec Sheet<\/h2>\n<ul>\n<li><strong>Main Category:<\/strong> All-Around, Inflatable<\/li>\n<li><strong>Board Dimensions:<\/strong> 10\u20196 x 32.5\u201d x 6\u201d<\/li>\n<li><strong>Listed Board Weight:<\/strong> 19.8 lbs<\/li>\n<li><strong>Listed Max Capacity:<\/strong> 320 lbs<\/li>\n<li><strong>Recommended PSI:<\/strong> 14-16 PSI<\/li>\n<li><strong>Fins:<\/strong> 9\u201d twin-fin; snap lock system with tether<\/li>\n<li><strong>Paddle:<\/strong> 5-piece carbon shaft w\/ nylon blade<\/li>\n<li><strong>Materials:<\/strong> Woven drop stitch w\/ triple PVC layers and carbon fiber rails<\/li>\n<li><strong>Price Range:<\/strong> High<\/li>\n<li><strong>Warranty:<\/strong> 3 years<\/li>\n<\/ul>\n<h2>Performance Review of the Blackfin CX Ultra  Stand Up Paddle Board<\/h2>\n<figure id=\"attachment_10683\" aria-describedby=\"caption-attachment-10683\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-11.jpg\" alt=\"Blackfin CX Ultra iSUP Review\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10683\" \/><figcaption id=\"caption-attachment-10683\" class=\"wp-caption-text\"><em>Maintaining an impressive level of rigidity, the Blackfin CX Ultra enters into the category of high-performance all-arounds.<\/em><\/figcaption><\/figure>\n<h3><strong>Overall Score: 9.9\/10<\/strong><\/h3>\n<ul>\n<li><strong>Stability:<\/strong> 9.6\/10<\/li>\n<li><strong>Speed:<\/strong> 9.1\/10<\/li>\n<li><strong>Tracking:<\/strong> 9.4\/10<\/li>\n<li><strong>Maneuverability:<\/strong> 9.2\/10<\/li>\n<li><strong>Construction Quality:<\/strong> 9.8\/10<\/li>\n<li><strong>Features\/Accessories:<\/strong> 9.8\/10<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><a href=\"https:\/\/geni.us\/blackfin-ultra-cx\" class=\"large radius otw-button\" style=\"background-color: #3b5998;\" target=\"_blank\">Check Prices<\/a>\n<h3><strong>Stability Rating: 9.6<\/strong><\/h3>\n<p>The Blackfin CX Ultra is about 32.5\u201d wide, so will provide plenty of lateral (side to side) stability to keep most paddlers confidently on their feet. <\/p>\n<p>That being said, the CX Ultra is performance oriented, and therefore a bit more responsive as you shift your weight between feet. Additionally, the tapered tail slightly decreases volume and surface area in contact with the water, swapping in a bit of sportiness instead of extra stability. It is not quite as stable as the standard (non-compact) Blackfin line or the similarly sized standard iROCKER 10\u20196 Cruiser. <\/p>\n<p>That\u2019s not to say the stability difference on the CX Ultra is major though, as it\u2019s a hair more stable than the iROCKER 11\u2019 All-Around Ultra, and about on par with the iROCKER Cruiser Ultra, despite being a shorter, more maneuverable SUP.<\/p>\n<h3><strong>Speed Test: 9.1\/10<\/strong><\/h3>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 740px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/File_000-9.jpg\" alt=\"Blackfin Ultra CX Speed Test\" width=\"750\" height=\"979\" class=\"aligncenter size-full wp-image-10685\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The Blackfin CX Ultra bested the 10\u2019 All-Around Ultra by a couple of seconds.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10684\" aria-describedby=\"caption-attachment-10684\" style=\"width: 740px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/File_000-10.jpg\" alt=\"Blackfin Ultra CX Speed Test - Casual\" width=\"750\" height=\"979\" class=\"aligncenter size-full wp-image-10684\" \/><figcaption id=\"caption-attachment-10684\" class=\"wp-caption-text\"><em>Even at a more casual stroke rate, the Blackfin CX Ultra kept up a decent pace.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>Despite being half an inch wider, the Blackfin CX Ultra proved slightly faster in our sprint test when pinned against the 10\u2019 All-Around Ultra from iROCKER. It came across the finish line relatively quickly in our casual paddle test as well, being nearly tied with the narrower 32ish\u201d SUPs in iROCKER\u2019s Ultra line. <\/p>\n<p>We think the tapered tail comes into play here as well, since the decrease in surface area that we discussed above should help limit the amount of drag and friction produced against the water. I\u2019d also credit this SUP\u2019s above-average stiffness, as it limits any performance-hindering flex or \u2018taco-ing\u2019 to keep the board\u2019s rocker consistent as you paddle. Lastly, I think the CX Ultra\u2019s lightweight build is also a contributor; being just 19.8 lbs, this SUP paddles with ease and picks up speed with just a few quick strokes.<\/p>\n<p>The Blackfin CX Ultra will easily keep up with a group of friends, and will likely even stay towards the front of the pack. We think it\u2019d make an awesome choice for paddlers who want a bit more speed out of their all-around without trading too much in stability or maneuverability. <\/p>\n<h3><strong>Tracking: 9.4\/10<\/strong><\/h3>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-33.jpg\" alt=\"Blackfin Ultra CX Tracking\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10685\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The tight, twin-fin set-up doesn\u2019t allow for much side to side sliding in the tail of the CX Ultra, giving this SUP excellent tracking capabilities.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10684\" aria-describedby=\"caption-attachment-10684\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9.jpg\" alt=\"Blackfin Ultra CX Tracking Abilities\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-13097\" srcset=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9.jpg 1200w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9-300x200.jpg 300w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9-1024x683.jpg 1024w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9-768x512.jpg 768w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-9-50x33.jpg 50w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-10684\" class=\"wp-caption-text\"><em>The Blackfin CX Ultra will naturally hold its course if you keep good form, but is still very forgiving even if you\u2019re more relaxed in your stroke technique.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>As with the entire Ultra line-up, the Blackfin CX Ultra tracks exceptionally well as a SUP in the all-around category. <\/p>\n<p>The 9\u201d twin fin set-up just seems to get a really firm grip on the water and doesn&#8217;t allow for much side-to-side sliding in the tail, enabling the paddler to move in a straighter line without having to frequently switch sides. <\/p>\n<p>We even found that the effect of the twin fin set-up is more exaggerated on the Blackfin CX Ultra than it is throughout the rest of the iROCKER Ultra line. We\u2019d estimate that because the tapered tail on the CX Ultra pushes the two fins into a tighter formation, they are able to trap more water between them, limiting tail sliding even further and subsequently improving tracking to an even greater degree. <\/p>\n<p>Of course, this is just our best speculation, and we cannot say with 100% certainty that the difference in fin spacing is fully to blame for the CX Ultra\u2019s noteworthy tracking capability. Another component at play is, again, the CX\u2019s stiff construction, which results in more consistent water-to-board contact\/drag and also helps to keep this SUP moving in a straighter line without too much adjusting from the paddler. <\/p>\n<p>In short, there are a multitude of attributes involved in the Blackfin CX\u2019s seemingly natural ability to hold its course in the water. However, it\u2019s important to remember that your paddling form is the final piece of the puzzle. With great form comes great tracking, and vice versa.<\/p>\n<h3><strong>Maneuverability: 9.2\/10<\/strong><\/h3>\n<figure id=\"attachment_10683\" aria-describedby=\"caption-attachment-10683\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13.jpg\" alt=\"Blackfin Ultra CX Nimble\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-13096\" srcset=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13.jpg 1200w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13-300x200.jpg 300w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13-1024x683.jpg 1024w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13-768x512.jpg 768w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-13-50x33.jpg 50w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-10683\" class=\"wp-caption-text\"><em>Justin found the Blackfin CX Ultra to be the most nimble of the Ultra series, and loved how aggressively he could sink the tapered tail for a step back turn<\/em><\/figcaption><\/figure>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-14.jpg\" alt=\"Blackfin Ultra CX Pivot Turn\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10685\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>Even with a less aggressive stance, the lightweight Blackfin CX Ultra makes it easy to lift it&#8217;s nose and pivot the SUP in any direction.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10684\" aria-describedby=\"caption-attachment-10684\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-7.jpg\" alt=\"Blackfin Ultra CX Sweeping Turn\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10684\" \/><figcaption id=\"caption-attachment-10684\" class=\"wp-caption-text\"><em>The Blackfin CX Ultra is a bit slower in sweeping turns than the standard all-around 11\u2019, but not so much that it hinders your overall experience.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>Given how well the Blackfin CX performed in our tracking tests, we were expecting it to make an understandable trade-off in maneuverability. However, the CX Ultra surprised us here, and proved just as maneuverable as the 10\u2019 Ultra and even more so than the Cruiser Ultra. <\/p>\n<p>While not quite as maneuverable as some of iROCKER\u2019s non-compact SUPs that sport a 2+1 fin set-up, the decrease is fairly minor. Backstroke and forward sweeping stroke turns are still effective; the initial change in direction just requires slightly more effort than we had become accustomed to on some 2+1 fin set-up all-arounds. I\u2019d attribute this to the fin set-up, of course, but I also think it has to do with the fact that the CX Ultra is able to pick up a bit more speed, making redirecting that momentum a little harder. <\/p>\n<p>That being said, the lightweight build on the Blackfin CX Ultra combined with its tapered tail make lifting the nose and sinking the tail for a stepback turn much more manageable, even for lighter or less experienced paddlers. <\/p>\n<p>Overall, the Ultra line-up as a whole, and the Blackfin CX Ultra specifically for this review, are plenty maneuverable for most paddlers. However, paddlers that are needing a SUP capable of quick turns with just a couple of strokes (i.e river paddlers, big wave ocean paddlers) would benefit from swapping out the 9\u201d twin fins for a pair of iROCKER\u2019s shorter side fins. <\/p>\n<h3><strong>Construction Quality: 9.8\/10<\/strong><\/h3>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-27.jpg\" alt=\"Blackfin Ultra CX Rail\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10697\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>iROCKER\u2019s Blackfin line is built with a carbon fiber rail, slightly increasing rigidity and durability.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-25.jpg\" alt=\"Blackfin Ultra CX PSI\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10696\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The entire Ultra line has a recommended pressure of 14-16 PSI.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-31.jpg\" alt=\"Blackfin Ultra CX Seams\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10699\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>Every iROCKER\/Blackfin SUP has reinforced seams.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-22.jpg\" alt=\"Blackfin Ultra CX Folding\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10699\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The Ultra line is made to be folded up the middle (hotdog style), to fit into the upgraded, compact SUP bag.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>Construction on compact SUPs never ceases to be impressive, and the Blackfin CX Ultra has raised the bar in this category. <\/p>\n<p>Differing from their standard, non-compact line, iROCKER constructed their Ultra line with a woven dropstitch inner core, which achieves more stiffness than a linear drop stitch core while using less material (i.e. creating a lighter board). <\/p>\n<p>The Blackfin CX Ultra is then coated with 3 composite layers of PVC (\u2018composite\u2019 meaning each layer is of different thickness), for added stiffness and overall durability.

I\u2019d interpret this as a testament to the effectiveness of a cross or \u2018woven\u2019 drop stitch pattern in producing a lighter SUP without detracting from stiffness. <\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/geni.us\/blackfin-ultra-cx\" class=\"large radius otw-button\" style=\"background-color: #3b5998;\" target=\"_blank\">Check Prices<\/a>\n<h3>Features\/Accessory Review: 9.8\/10<\/h3>\n<p>Though compact, the Blackfin CX Ultra does not skimp out on versatility focused features.<\/p>\n<figure id=\"attachment_10683\" aria-describedby=\"caption-attachment-10683\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-16-1.jpg\" alt=\"Blackfin Ultra CX Accessories\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10683\" \/><figcaption id=\"caption-attachment-10683\" class=\"wp-caption-text\"><em>From nose to tail the Blackfin CX Ultra has a front carry handle, removeable front cargo area w\/ a pair of grab straps and 2 incorporated action mounts, kayak seat compatible D-rings, an offset center carry handle, a removeable rear cargo area w\/ another pair of grab straps, a third action mount, and a rear carry handle. <\/em><\/figcaption><\/figure>\n<figure id=\"attachment_10683\" aria-describedby=\"caption-attachment-10683\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18.jpg\" alt=\"Blackfin Ultra CX Twin Fins\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-13098\" srcset=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18.jpg 1200w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18-300x200.jpg 300w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18-1024x683.jpg 1024w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18-768x512.jpg 768w, https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-18-50x33.jpg 50w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-10683\" class=\"wp-caption-text\"><em>The Blackfin CX Ultra&#8217;s twin fin set-up sits closer together than the other &#8216;Ultra&#8217; SUPs due to it&#8217;s tapered tail; we think this is why it excels above the rest in our tracking tests.<\/em><\/figcaption><\/figure>\n<p>One of our favorite features on the CX Ultra is the removeable bungee cargo areas. iROCKER added a clip to their bungee system that you can simply undo, to thread or de-thread your cargo areas without having to cut and replace your tie-down bungees several times over.

Included with each Blackfin CX Ultra is the following list of accessories:<\/p>\n<ul>\n<li>5-piece carbon shaft paddle w\/ a nylon blade<\/li>\n<li>iROCKER 12V Electric Pump<\/li>\n<li>9\u201d snap-lock fins (x2)<\/li>\n<li>10\u2019 coiled leash w\/ key pocket<\/li>\n<li>Accessory Pouch<\/li>\n<li>Compact roll-top\/front zip backpack<\/li>\n<\/ul>\n<p>Firstly, we love iROCKER\u2019s decision to include their 12V Electric pump with their Ultra line. Any electric pump will make for a much more enjoyable inflatable paddle boarding experience, but iROCKER\u2019s electric pump in particular is one of our favorites in the industry. It\u2019s fast, reliable, and its shape and cord compartment make it super easy to fit in a SUP bag. This pump even holds second place on our list of <a href=\"https:\/\/www.supboardguide.com\/best-electric-pumps-for-inflatable-sups\/\" rel=\"noopener noreferrer\" target=\"_blank\">Best Electric Pumps<\/a>. <\/p>\n<p>Moving to one of my personal favorite pieces of this kit, the accessory pouch is not only the perfect spot to store the electric pump, but it also has extra room to hold your fins, leash, and any other small accessories in your arsenal that would otherwise get lost in the backpack.<\/p>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-42.jpg\" alt=\"Blackfin Ultra CX Backpack\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10685\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The Ultra series packs into a SUP bag that is slightly larger than an average backpack.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10684\" aria-describedby=\"caption-attachment-10684\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-44.jpg\" alt=\"Blackfin Ultra CX Molly Loops\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10684\" \/><figcaption id=\"caption-attachment-10684\" class=\"wp-caption-text\"><em>Decked out with molly loops on both shoulder straps, this bag is easy to clip a water bottle for a moderate hike.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>Staying on the topic of the backpack itself, we\u2019re essentially in love with it.

Once the front panel is re-zipped, the bag functions with a velcro roll top, which allows you to load anything on top of the SUP without having to wrestle with a zipper to get it closed. So far we\u2019ve just been placing the accessory pouch on top for easy access, but there&#8217;s plenty of space to take along an extra set of clothes or some towels. <\/p>\n<div class=\"side-by-side-images\">\n<div class=\"side-image\"><figure id=\"attachment_10685\" aria-describedby=\"caption-attachment-10685\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-45.jpg\" alt=\"Blackfin Ultra CX 5 piece paddle\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10685\" \/><figcaption id=\"caption-attachment-10685\" class=\"wp-caption-text\"><em>The Ultra line\u2019s 5-piece paddle is able to adjust to a variety of taller paddlers.<\/em><\/figcaption><\/figure><\/div>\n<div class=\"side-image\"><figure id=\"attachment_10684\" aria-describedby=\"caption-attachment-10684\" style=\"width: 1190px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.supboardguide.com\/wp-content\/uploads\/2022\/05\/Blackfin_CX_Ultra_Written-Review-46.jpg\" alt=\"Blackfin Ultra CX Paddle Height\" width=\"1200\" height=\"800\" class=\"aligncenter size-full wp-image-10684\" \/><figcaption id=\"caption-attachment-10684\" class=\"wp-caption-text\"><em>Even when adjusted to it\u2019s shortest height, the 5-piece paddle is still a bit too tall for me at 5\u20192\u201d tall.<\/em><\/figcaption><\/figure><\/div>\n<\/div>\n<p>Our only suggestions on future versions of this kit would be for iROCKER to include a shorter pair of twin fins (maybe in the 7\u201d range) that would allow for a bit more maneuverability, as well as adjust the paddle design to adjust to shorter paddlers.
