What we say
The Starboard Twin Fin 2025 is a fast, lively, and super fun board to surf. On the wave, it immediately feels light and responsive underfoot, with a real sense of freedom. It picks up speed quickly down the line and carries that momentum effortlessly, especially in smaller, clean conditions where it really shines.
The twin-fin setup gives the board a smooth, skatey feel with less hold than a thruster, but loads of flow. You can draw out your turns with style, yet still snap tighter lines thanks to the hip in the tail and moon tail shape, which offer a nice balance of looseness and control.
At just 4.5kg, the 7’3″ model is incredibly light. You can feel that weight savings translate into performance — the board reacts quickly to input and has great flex and spring coming out of turns. The Acute Custom Carbon construction is clearly tuned for high responsiveness, making it feel energetic and alive underfoot.
The thinner rails on the smaller sizes help with bite and control, while the slightly thicker rails on the bigger models add some forgiveness and float. Adding the knubster centre fin gives a touch more grip for those who want to push harder through turns, but the board feels great with or without it.
Overall, it’s a stylish, performance-focused board that encourages flowing lines, speed, and creativity on the wave. Ideal for riders who want something a bit different and exciting in their surf SUP quiver.

Pros: Insanely lightweight. Fast and smooth on a wave. Premium construction — Acute Custom Carbon offers great flex and recoil. Skatey twin-fin feel — fun, different, and very adaptable with optional knubster.
Cons: Small recessed handle — difficult to grip, especially with gloves or larger hands. Ultra-lightweight feel isn’t for everyone — some riders prefer the hold and glide of heavier boards, especially in windy conditions.
Consider buying if... You’re an intermediate to advanced SUP surfer looking for something fresh and fast. You surf waist- to head-high+ waves and want to link turns with style. You won't be disappointed.

What the brand says
“FAST LINES, FREE SLIDES”
Experience a board engineered for speed and freedom. The TwinFin’s unique shape, with a pronounced hip behind the fins, delivers dynamic, agile turns and a loose, skate-like ride that lets you carve high-line rail maneuvers effortlessly. Its innovative channel tail boosts acceleration and aids tail recovery during radical slides, keeping you in control on every wave. Whether you’re tackling small, less-powerful surf or challenging overhead conditions, the TwinFin empowers intermediate surfers to push harder turns while offering advanced riders a high-performance, fluid ride.


















Thanks for the video Beau. It looks so easy to transport. I could carry that a long way to the beach. However the handle might make it harder to hold for long distance. Is an inch or two longer handle really more dangerous for surfing ?
Hey Cameron, I would say they have drop the handle length to save weight. I have never had a problem with any handles surfing.
Thanks Reuben.
Beau mentioned that the board might be a little too light for some people. I wonder if its better to make the handle more comfortable rather than save a tiny bit of weight ?
It would do and it could be a good idea. But I know some riders that would prefer a lighter board and would be happy to use a smaller handle also. It’s always a hard balancer for bands to get in 100% right for everyone.
Fantastic review! I have a question about the bottom shape. In most surf sups, there is a single concave heading down to a double that creates lift and a pivot point under the back foot. With the Twin Fin the concave at the back looks like it would create lift but not a natural pivot point. Does that mean the board turns more from the middle rather than the tail? I feel like it looks that way in the videos.
Hi Thomas. Great question. The single concave definitely improves lift and it’s also to increase the speed of the board down the line (it’s fast!). The single concave also helps with hold when surfing on rail – but you need to get it on rail for it to work. There were some points (especially the first few waves) where the board felt like it wanted to surf very flat and seeing your comment, makes me think it was the bottom shape as it didn’t transition as easy as a double concave or vee bottom. It just a case of surfing… Read more »
Great review, and some fine surfing too!! Extra excited about getting one now (September I hope). How much difference in feel was there between pure Twin and twin + 1? Thanks
Thanks Paul. By using it as a 2+1 I definitely noticed a little more hold and grip when turning. You can still push that little bit harder on the turn and slide it out though. I’d probably lean more towards riding the pure twin fin set up when it’s small (waist high) and then add the +1 in when it’s chest high and bigger. But I do believe that the larger sizes might need the +1 in the back just to add a bit more grip as the boards get wider.
Thanks
Hi, bit of advice as you have helped me with board choice previously. Have a few performance boards but looking at a twin for smaller surf. I have a Starboard Pro for decent waves and a Sunova speed both of which I love. Looking at this SB Twin or the Infinity Escape Pod for a different feel in mostly smaller waves. Tricky question but does this perform in anyway similar as a twin (without the nubster) in smaller waves given that it obv has the ability to handle bigger surf and is therefore more versatile…..looking for a board to link… Read more »
Hey Michael, Good question and this board would really add to your quiver…but which one! My thoughts on the 2 boards are- The Infinity is a super fun board to use, better in swell under head high only, super super fast and very exciting to surf, light and loose under foot. It is very different to what your other boards do now. The Starboard Twin, wether you are using as a twin fin only or with the nubster fin. Its fast but not as fast as Pod, but not for behind and it works in a much larger swell range,… Read more »
Hi Beau
Great Video review. Much appreciated. Really enjoyed.
So what’s best, the Escape pod or Twin Fin?
Thank you both.
Size question: Have youridden any of the other sizes? I was looking into buying my first wave-riding SUP and based on my needs, I’m pretty sure the Twinfin is the choice for me. I’ve had two cervical spinal fusions in my neck and have limited range of motion looking up, making paddling on a traditional surfboard very uncomfortable. I’m an intermediate surfer and will mostly be surfing in knee-head high beachbreak waves. I want the maneuverability of a shortboard, but I want to make sure the board is wide enough for me to balance on when paddling. I am 5’7”… Read more »
Hey Dave , good question. Things to be aware of, you’ve obviously got a good understanding of wave riding but you might find the hardest thing for you is the transition of paddling a shorter (for a SUP) board onto the waves. In other words paddling in a straight line to catch the waves. What size boards have you used in the past? Because these twin fins do tend to require a little bit more skill compare to a more traditional 2+ one fin set up.. I understand what you mean about wanting the board to still surf aggressively. Another… Read more »
Thanks for getting back to me and for the information. I used to surf very thin shortboards in the 5’5″ – 5’10” range in my twenties and thirties. I also surfed on a short, thick twin fin fish quite a bit as well and had a blast on it. About ten years ago I started surfing on my 7′ fun shape and 9’6″ longboard more due to injuries and loss of flexibility due to neck and back injuries. I have ridden on a short, thick twin fin fish quite a bit as well and had a blast on it. I… Read more »
Got it, yeah for you on a wave you need a 8’3×30. Im sure this will offer you something to progress and grow into as well. It will be harder to paddle in on, but thats something your can practice alot on flatwater. With all your surfing background the extra width of 32″ boards on a wave wont be needed. How does that sound?
