searched the forums. not much info.
cant believe there is nothing on this in the forums.
any of you ever make a thruster with no toe in?
How does it ride?
thanks,

Works fine if you have juice, speed, size, lots of V, some rocker, curved tail outlines, and your style is to stand on your backfoot to do your surfing. It becomes more a single fin with holding help, as opposed to a true thruster concept. Most guys without toe in use smaller side fins to help the main fin, rather than work as a cluster.
But 3 equal sized fins, maybe not, especially for 180 cutbacks.
Actually there is a lot of info on it!
The search function doesn’t work very well.
put the following line in google:

On small tow and kite boards yes. If ya want the board to turn ya need a little toe. If you only want to point and go then fine it would be fast down the line but talk about tracking!
thanks
can you say.............track attack !

Bill T is an advocate for 0 toe in.
Because of him I've set all my 4WFS boxes to 0 toe and swapped for a template that is supposed to be too small for me. WOW, to say that it was an improvement is an understatement.
One area greatly improved was the wave catching.
But as per Herb. It did track a bit on faster, steeper waves. My foot positioning is inconsistent, so that exagurated the tracking on some waves. Also the board was not built with 0 toe in mind.
But im a fan.
retrothis,
Have you tried it in both big and small waves? Same effect?
Hi hans!
First session with 0 toe was in waist to shoulder high waves, a few weeks ago.
The second time was this past Saturday. Waves were head high and above.
Both session clean offshore conditions.
In both sessions the board caught waves better. On the smaller day, I did not feel any tracking. It was easy enough for me to overpower the board in slower smaller waves.
In bigger conditions it was easy for the board to overpower me, espesially when I got my foot placement wrong on a rushed takeoff. On the waves where I got it right, the board did not track as such, but I did feel....limited in where I could point the thing. But no lack of speed though.
So Im a fan because of the wave catching. There were few and far between that passed under me with out catching them, which was a massive improvement compared to the bigger, toed in foils.
(Above) Board with BIG f16 fins.
New side fins were 4 K.G X small, see here: http://www.4wfs.com/images/march09/fact%20sheet1%20gfkfoil.pdf
…its like LeeD says; no toe in is not a Thruster concept; its a 3 fin board (2+1, etc)
-hello Retrothis; in my opinion you still manage to loose the board due to those fins (vertical aspect, etc)

Hello reverb!
My apologies, but I can't figure out what you mean.
hi retrothis !
.... did you have a larger back fin , with the two smaller ones , or were all three fins that smaller template ?
cheers !

Hi Ben
I had 2 small "4KG" side fins and the F16 centre fin.
Now that you mention this, the larger centre fin might have contributed to trackiness.
Unfortunately, I dont have any other 4wfs centre fin. The "4KG" fins were bought as sidebites for a 2+1 setup using the RFC Mysto cutaway.
Seems like I've been overfinning all my boards.
Always try to use the minimum amount of fin that still allows you to take off lateangled, and do strong bottom turns.
Notice almost all gun boards look underfinned. Better to be slightly under finned than over finned. A forgiveness factor.
…I say that with 0 toe in and STD fins is even more difficult to have small action turns; however, rapid down the line.
So with these other fins template you still can turn fairly good caring less of the 0 degree
or …
to put it another way …
upright fins …pivotal
rakey fins …more drawn out turns
smaller fins …looser
I have a question? Have any of you tried dub foiled front fins in an effort to free up the turning characteristics of straight fins. Even 70/30 foils? I mean we put twin fins on pretty straight and if the fins are placed in a tighter cluster I could see some adjustable benefits maybe?
I don’t know about straight fin clusters in bigger boards. The longer the board the straighter the outline. Its like your battling two evils. You can’t loosen up a board when you design it to go straight.
Interesting post. You have my brain spinning out
hi sano
not entirely straight pointing side fins , no ...
but i use double foiled side fins a LOT of the time ,
in fact i asked on a thread long ago [?chipfish61 days , perhaps?]
WHEN and WHY we switched to single foiled side fins on thrusters
I'm pretty sure from the 'morning of the earth ' footage shot on the beach [1971?] of [? owl chapman's ? ]'three finner' , that the two small straight facing sidefins are double foiled , yes ?
[the inspiration for some of terry's boards , perhaps ?
cheers !

Yes.
