Well I finally got some decent surf in which to try your fin.

I LOVE IT!!!

It screams out of turns just as you promised, I just may have to get a few more…. I promised to send photos of my work, so enclosed you should find a few. Thanks again for your fin, it brings yet more fun to my surf!

Aloha!

I’m so glad you are getting this fin to market because I have ridden them and I really believe in them. To me they are the future of surfboard fins and I tell everyone that will listen that eventually everybody will move across to fins like this. To put it simply, the fins work so much better than regular fins.

Thanks!

Hey!! Just tried it out on my Stand Up Paddleboard. Amazing!! Thank you. What a difference. #1 The board tracks better. # 2 Hauls ASS! # 3 Turns on a dime. # 4 Seems to lift my nose up when I’m doing long powerful paddle strokes to get better speed. # 5 Board seems more stable…

All hard to believe, but I totally noticed the difference immediately.

My Stand Up Paddleboard is 11 feet by 30 inches and now spins a 180 with one stroke…

Sincerely, Sandy.

Just wanted to let you know that the day I received my new Wavegrinder longboard fin I fitted it on my board at lunchtime ready for a quick dash down for a surf after work. Beautiful little point breaking waves. Oh boy, what fun. I exhausted myself very early in the session. Hadn’t caught so many waves in such a short amount of time before. The fin seemed to allow me to paddle onto the waves much easier, the board felt more loose than previously and I got to the nose better than before. What a blast of fun.

Thanks.

I bought a wg2 for my 9’2″ longboard and I love it.  Thx for the science.

The WG2 fin is awesome, I’ll never ride a traditional raked fin in my single fin longboards again, as when I retried my regular set up, the board felt drunk in comparison.

I gave that Wavegrinder fin a real workout in Baja over the weekend and had a lot of fun with it. We had consistent glassy surf for three days that ranged between 4’ and 10’. As an old traditionalist it was quite different trying something that new and I found it to be everything you said and more. My turns were very smooth and the transitions from a cutback to a bottom turn were fast and I didn’t notice any stalling, obviously I really liked it! For surfing Costa Rica, the Dominican Republic and at home I will certainly be surfing the Wavegrinder.

I just want to give you some feedback. I’m 6’1” 210 pounds. I prefer to ride shortboards but when the surf gets small or during the winter I will ride my longboards. When I do ride them I tend to ride them more like a shortboard. I like performance surfing. I read your ad and decided to give it a try. I have had the Wavegrinder for a few months and I love it. I have it in a 9’1” McTavish Original. I rode it with two FCS h2 side fins. I could immediately tell the difference in the performance. Then I ran up to the nose and got the longest nose ride of my life. Well the water started to warm up and the surf has been good, so I have been riding my shortboards. A couple weeks ago I went down to Hatteras, NC, for a little vacation and had good surf all week. The swell did drop toward the middle of the week, so I pulled out my longboard and was getting some good rides. My buddy has never seen the Wavegrinder before and I was telling him about it. He asked if he could try my board and he loved it. He was getting sick rides. He said he wanted to borrow my board for a contest. I told him it’s not the board, it’s the fin. He didn’t want to give the board back. I gave him your web page and he said he was going to order one. I’m getting this one for a 9’6” Hamilton. Can’t wait.

Thanks!

I can say I have had maybe 4 surfs in the last 2.5 years on regular fins and each time I feel like the dolphin fins are just so slow by comparison.

I loved the fin in the single-fin shortboard. I tried it in a bonzer 5 setup, and single fin gun, a couple of different longboards, and a single fin shortboard. It worked far and away the best in the single fin shortboard, and very good in the bonzer too.

The fins are AMAZING!  So much speed out of a turn and paddling couldn’t be easier. My brother and I are very impressed. I’ve been out several times this week and I couldn’t be happier, today was a little steep but the fin put me in quicker so I was down the line before the wave could get me.  We are spreading the word so hopefully you will get more orders. By the way, the turning is so quick we had to put the fin 3/4 of the way towards the back of the fin box. My brother kept throwing himself off his board it was so quick!

Thanks for a great invention.

Tom Blake would be proud.

I LIKE IT!!!  Played in some 3-4’ stuff in HB this past weekend and had great fun. Allowed me to get that 10-0 around pretty quickly. Steady while at the nose too.

I had it moved about two inches behind where I usually place the other fins.

Good fun . . . . I look forward to better waves with it.

While waiting for my new board to arrive, I ordered a Wavegrinder. After having ridden the new board with the 2 +1 fins sent with it, I switched to the Wavegrinder and went out in 5′ to 7′ surf. I was surprised how much easier paddling out was and how much faster the board seemed. Your fin performed just as advertised. I’m going to order another for my noserider.

firstly, i’m a huge proponent of your fins. as a fan of physics, i enjoy understanding the design elements used and share that info whenever i engage other surfers who ask about the fin when they see it.

i ride a rick rock 9’6” rounded-pin with your semi-flex fin. it rides very predictably and doesn’t cavitate on harder bottom turns. it accelerates quickly, pivot- and carve-turns confidently and holds great while nose-riding.

thanks for making great fins!

regards,

In small waves, I was surprised by how my board ( 9′ Surftec, epoxy, Takayama) snapped off the top, and there was even some speed left to do the bottom turn. Yesterday I got it in head-high at Torrey Pines. The board seemed faster down the line, the snaps off the top and bottom were no problem.

Just wanted to give you some positive feedback regarding the Wavegrinder fin. I’ve been surfing it for a few weeks now and am completely stoked. First time out, I was most impressed by the projection out of bottom turns and the sensation of feeling the fin flying thru the water. Per the recommendation I had the fin a few inches back than normal for me. The next time out I moved it up about an inch and a half to see the difference. Didn’t work nearly as well. Interesting that the placement makes such a difference. Very seldom does any new product or innovation live up to its claims, but the Wavegrinder exceeds by 100%. You’ve increased my stoke considerably, which I didn’t think was possible. I wish you much well-deserved success. thx

I recently replaced the fin on my 9-footer with the Wavegrinder Fin and took the board out for a test at San Onofre. The fin worked great all around on a 1-4 foot surf with glassy conditions all day. The first sensation I experienced is the board paddled exceptionally fast. In fact I was surprised how fast I got out through the inside surf. Catching the wave was much quicker–the board gained momentum with each stroke–definitely a plus when there is a crowd. Once I was on the wave the board would pick up speed faster than my regular fin and I could turn the board in a tighter radius, a pivot-type turn with no loss of speed. The glide was great and nose riding was smooth and effortless and cutbacks were also smooth. The straight line speed had drive which amazed me for a fin with a narrow base. I can’t wait to get the fin out in overhead surf.

Thanks Again!

Hello Doug,

Am still using your fins [longboard kiteboarding] with great results. I always talk them up here in bustling Cleveland and around the Great Lakes.

I hope this finds you well.
