Tri fins don't track?

[GERsurfer]

The Naish TriFin is really slow to plane and needs more wind to get going/get upwind. I've seen the board and thought they were kidding me when I saw the fins. They are just some piece of cr.p - no airfoil at all. I know a guy who is sponsored by Naish and the first thing he did was changing the fins. Now the Board works better but is still pretty slow. Once on a wave, he said it's the best board he ever had.

Owning a Naish Prowave (2007) that was converted to a tri-fin and having riden later model Naish wave designs, I can offer some insights. The flagship Naish wave boards are no compromise wave designs, which does mean they require a good amount of wind to unstick when not on a wave. Once powered they drive upwind quite well. On a wave, these boards really, really shine. They are the best wave boards I've sailed, but I make that statement not having spent time on a whole lot of time with other board brands.

As far as tri-fin goes, a 21 cm rear with 9 -10 cm fronts just doesn't change the character of the board by much over a single fin - in fact you are simply adding fin area without any real benefit, resulting in more drag instead. Also, while Naish smartly put some toe into the fronts (about 1.6 degrees), it is still too little. I'm running 11.5 - 12.5 cm front fins and 16.5 cm rear with toe-in about 3.5 degrees for symmetric fins and as much as 5.8 degrees for asymmetrics. Furthermore, the front fins need to have progressive twist to minimize drag. Based on my experiences, I conclude Naish to be too timid in its foray into tri-fin boards.

It has imo nothing to do with the toe in and finsizes, its all about the rocker and the tail.
I sailed the board and yes its need some serious grunt to get going and stay planing but when you just ignore that and slog outside its an awesome board when you are on a wave that turns tighter as almost anything I sailed.
I really really liked it for what it is: a slog and riding board for side to off shore reefbreaks.
too bad I live at a strong current side-on slow chaotic beachbreak

a lot of the description applies to my Nasih Hybrid Wave, trailer fin. both Mike and myself felt it needed more toe in. K4s with 2 degrees on order. Have some surf fins that I molded into slot box to try as well.........

as well I do feel that Naish wave boards are no compromise, they are wave machines

I'd really like to see a test of the new 2013 Wave board http://www.naishsails.com/2013/wave/

Looks like an awesome board, unfortunately there are only two (small) sizes.
I don't think any magazine has tested this one yet.

For the record, I have 3 Naish boards, now.

Up wind has on all my tri fins, all 5 of them a serious plus.

Not getting 2old2write2 are you
