a longboard with keel fins?
48 views and no replies. must not be too many of keel fins on longboards. there are only a couple of twin fin longboards in the archives, too. I’m thinking of slapping a couple of symmetrical wood keel 9x5s on my 9’1" with just a skosh of toe-in, whaddayathink?
does a winged keel count? gotta love that StarFin!
That would be fun to ride…Although I definitely wouldn’t go with a skosh of toe-in, but possibly a tad. 
It’s not my area of expertice. But, don’t King Fish sport keel fins?
I have and ride one of those (not two at the same time though!) It’s a really different feel…
What fins did Skip have on his huge boards that he used on his north-then-south (or south-then-north) Cliffs surfing expeditions?
perhaps asymmetrically aligned symmetrical fins? Toe-in of a tad on the frontside fin and a skosh on the backside one? But what if I then switch-stance??? And my fin first takeoffs would be very confusing…
Clyde Beatty makes them but not too many these days.
Hey Keith , Denise was out in the front yard with Ginger and a lady walks by with a dauchsen and its name was Roxy, too funny! AAAnyway I had some keels when Nat Young was here doing Crystal Voyager and that is a good film to watch to see how they work.Only Nat could ride that board. I dont think the keels would go on a longboard. I have a bunch of Tracks mags with design articles on keels from that time, Pat Morgan from Torquey was the guy who started the thing , riding and shaping for big long walls of Bells.With longboards I think you would be takin a quick trip to the tip for a sideslip.Unless it was a nice pulled pintail??
I suspect you’re right there KP! Maybe I’ll try it anyway, I can always grind them off later… I was thinking of an ittty bittty trailer fin just to hedge the bet… maybe I should just mount the keel fins on end, eh?
make em outta rail cutoff foam with a bottom flange and zap a gap em to the bottom and just hot coat em low weight and low commitment…ambrose…acetone disolve cuts zap a gap so ya can relocate fin when tired…no grinder implications
yater has done a few that I looked at. Twins more like thruster templates, not keels. I’m not sure if he liked them or not but they were around for a while and he tested them out.

you can’t be a leader if you can’t say “mixed messages”
sounds good, but what the heck is zap a gap? some kind of expando-foam-glue?
i’ve got one, too…it’s a lot of fun. it rides REAAAALLLLYYY loose, but it drags a bit and doesn’t paddle as fast as other fins.

hi Keith !
I don’t think it was a longboard , as in a 10’ noserider or something, more like a long board, but… Scott Bass, over at the surfermag site has an orange [twin ] keel which , from memory, was about 8’ [??], I think. It was a pretty old post, it might be best to ‘pm’ him, maybe he can send you the photo. [It was in a quiver shot , so maybe it was an old ‘quiver’ thread?]
In the meantime, here’s a shot from about ? 1974 ? of SINGLE keel longer boards , which has a Dick van Straalen and a Pat Morgan or two in the photo, I believe!
If you look on my ‘fin photos’ thread, I think I posted a shot of one of Pat’s smaller, wooden SINGLE keels [compared to nat’s monster!!].
Wayne Lynch was the other guy who test piloted them, being that Pat Morgan was / is a fellow ‘Vicco’ [that’s Victoria, Australia]… see The Surfer’s Journal Wayne Lynch / Tom Carroll edition video / DVD…
I hope this helps!

[I think the longer board in the attached photo is about 8’ from memory…don’t know how to scan the article so it’s readable, unfortunately!]
I forgot to mention…
A year ago, I’d drawn up five different templates of single keels for my 7’ single fin [pintail, with finbox]. Just got to get some wood to draw them onto, cut them out of, foil then glass 'em, and see how they go ! [ Like I said, not a longboard, but a longer board [than the 5’11 fish I ride, anyway!]]
Here’s a shot of the 7’er I want to try 'em out on …yes, Soulstice, gotta love the winged keel!! [I often put one on this, and it’s HEAPS of fun… our beaches are pretty well weed-free now! which helps …]
