double foiled fish fins

[deathfrog]

when you make a wooden double foiled fish fin, as a glass on, do you just like make a point on the front of the fin tapering it on both sides, and leave it flat for the rest of the fin, or taper it down again on teh back. Im confused.

[jonny]

Double foiled refers to that the fin is shaped on both faces, like a longboard centre fin would be. The difference being, if you took a regular side fin such as an FCS or similar, it would only be foiled on one side, with the other side kept flat. An FCS CENTRE fin is foiled on both faces though.

And yes - you want both the front and back to taper in.

Good luck!

in fact - we have a couple retro twinnies stock right now so if you need a photo for reference just shout.

Check out the Swaylocks site also, alot of old-school (sic) board makers seem to hang out there, there are numerous threads on fins & design.

here we go - these photos are taken of a South Coast Retro Slide. A readl old school twin fin fish shape. Beautiful board. The fins are hand made 8" keel fins and glassed on.

This first one is the view from above - you can see the double foiling as the fin is shaped on both sides.



next is the view from the side so you can see the shape:



next an angled shot so you can see both fins and their position in relation to the side and tail for the board



a picture of the board itself


and finally a picture of the guy who made it ripping up Bell's Beach on one

awesome, that anwsers alot of questions. What about other stuff, like glassing and dimensions? Sorry again if im asking too much but yea, im researching...

[jonny]

this board is :

Length: 6'2"
Width: 21 3/4"
Thickness 2 3/4"
Tail: 18"
Nose: 17"

and is glassed in 10 oz Volan top and bottom - a heavy, chunky, fat, stubby, old school retro twinnie.

I love it!

here's more info - three different retro slides and then one form the master himself, a blue resin tint Tyler Deuce (Tyler is the guy who made the singlefin:yellow board and is generally regarded as making the finest longboards and retro brd in the world):

awesome, this stuff helps alot. They all have boxy rails for volume right? not much of any edge on it?
