Cool pics thanks, yeah looks chunky up front.
This is the outline I had drawn up but I will be changing that soon.

Would a big freestyle board (112l -68cm) with a twinnie set up work better in waves than its current single powerbox - slides like a mad thing trying to bottom turn too hard - but floats out nicely and gets goin pretty easy?

how hard would it be to convert one - or is are they just too flat and a waste of time

Check out my my pics of a single to twin conversion.

I think there might not be enough tail kick in those bigger boards to work with the fins.

While you can convert a single fin over to a twin fin, we haven't had much success.
As the bottoms and rail shape have to be differant to get the twin fin to work at their max performance.

HOLY SH1T ELMO!!!
Watching that vid made my freckle invert

can anyone give us the verdict on twin fin early planning, i read some contrary reports.. is twin fin only suitable for 25+ knots how about 20 or even 15+ knots?

is there such thing as all round twin fin board on the market now?

Here in Wellington, NZ, the guy who runs the main windsurfing shop here has, after heaps of demoing, decided to only stock twin fins this year! They get great feedback from any of the local crew who tries them. We get mostly cross on conditions, and the word is that they have the edge on the single fins in these conditions.

That's a big call for a shop owner to make eh?

I would have thought twin fins were meant for the more cross off fast DTL radical wavesailing and not mushy sh!t waves. Has starboard (and the rest of the big companies) just made a 'twin fin' for the everyday user to copy the hype or are these boards genuine DTL ripping boards. Im sceptical of all the brands doing this twin fin stuff apart from Quatro... Do these companies really know what they are doing or just jumping on the bandwagon. Twin fins were tried years ago but never took off like now. Is it because Kauli started using them (which suits HIS style) and done well on the tour that everyone thinks they are the stuff?? There are so many good single fin waveboards out there that I think would suit Aussie conditions better than the twins. Only because I believe the twins to be suited for the more epic highend scale of wavesailing which we get less of in Aus...so whats the go are they the goods??

Ive been riding a Jp 68ltr twinny for the last 4 mnths, being the only board Ive had has meant I ve been using it in a very wide range of conditions, heres a couple of thing Ive found
1. They are no slower than any single fin waveboard ( Ive used it in flat water and sailed alongside guys on freeride boards with no obvious difference in speed).
2. They work well in bigger surf and at high speed on the wave, Used them in mast high windang. Plenty of drive and bite out of the bottom turn and unbeatable off the top.
3. They tend to glide onto the plane as opposed to pop on like a single fin, however, I used a 76 twin on the weekend and found this sensation to be less profound than on the smaller board.
4. Great fun in smaller surf due to the tighter turning arc.
5 They head upwind just like any other waveboard
Im still waiting to try it in cross on, so have no coment there ( kind of sailed onshore last week but it was hard to tell in 12kts bolt onshore)
My general opinion of the twinfins Ive been riding is Ilove them. I dont understand all the skepticism, essentially they are just like any other waveboard but looser, which in my book is a bonus. Im sure there a hell of alot of demos floating around at the moment, why not go down to your local shop and try one, and while your there have a look at the different approach all the brands have taken to the twins. In a nutshell anyone thats likes a loose waveboard should give a twin a try, why would you not??

So far me and matt cliff are the only ones that I know of that have them, matt got his in maui and I got a pre production a few months back. We both love the twins. The rest of the shipments got in last week, so Im pretty sure be on the water real quick.
As far as an eastcoast board goes, I think they are great ( at least the ones Ive ridden are), Ide heavily recomend you try a few different brands though as the all seem to have a way different approach to incorporating the two fins into the design. I guess its kinda like single fin boards in a way, they dont all work the same and some are better than others for what your wanting to do. They are definately looser though.
Ide put money on it that MA will end up on one, he'll love the top turn.

Here, Here Brien....hows work been? You still in Mkvlle.

Your an idiot qwerty...how would that even work??!

And be careful who you call an idiot. There will be a lot of guns pointed at you in a few weeks!

I tried the no fin edition once after snapping a fin, hilarity did not ensue!

I'm going to work outside the square and say centreboards! We need centreboards....think of the upwind potential. Not sure the turning would be that crash hot though.
