D-fin foil

I’m shaping a heavy 8’ chambered cedar and white pine gunny longboard. I want to put a d fin on it and was wondering what the best kind of foil would be or if I even need to foil it at all (just round out the leading and trailing edges)

I’m not happy with the fin I made and I’m starting over on it.

thanks a billion!

Please post some pictures!

Foils didn’t really come on many D fins (if any), just foil leading and trailing edges to avoid hums and whistles and be content you have the best the surf world had to offer in the early 60s.

My first new Velzy & Jacobs, an 8’ 10’’ balsa ‘‘Bump’’, purchased in 1958 for $75, had a 5/8’’ thick Mahagony fin that WAS foiled. Very few other boards in the shop had a foiled fin. Most had flat sides, with a sharp taper all around the fin, about an inch into the flats. Even a foiled fin did not prevent the Bump from spinning out of hard turns.

check this previous post mate, it helped me no end!

There is a little out of sequence montage and a pic of the cut and trimmed blank. Its very flat, only 3" of rocker in the nose and tail with a foot and a half dead flat from the widepoint (4’) up 1.5’

Its got a soft rounded belly down to a foot off the tail where it turns to a V.

nose 18", wp 21", tail 14.5", 3" thick.

50/50 rails to 1’ off nose and tail. Nose is pinched, tail is hard down.

No pics yet of the finished deck (just used z-spar captains varnish. Its drizzly right now so I don’t want to take it outside)

Robbo, thanks for that link, don’t know how I missed that one.

I hope to have the fin finished in two days.

ps, I did even out all the inconsistencies of the outline (left side of the nose) before I varanished it
