Fin problems/advice

Postby paullindsay » Tue Apr 02, 2013 8:28 pm

I need a little advice on some fins i got with a board not so long ago,Its a firewire kingfish measurements are 5' 10",21",2 7/8",swallow,42.1l
Now the guy i got the board off only rode it twice and after riding i can see why,the fins just dont go with the board,i snapped a very similar dimesioned board with M.R twins on it and it went like a dream admittedly it was a little more rounded and retro the this one but very similar in dimesions. I can't id the fins that came with the board as have no name or any markings so have hopefully attached some pics of them,basically the board would barely turn,i wanted a nice loose twinnie be able to slide it around etc.. and these fins i think are the problem i think they could be just to big
Thinking about shaping them down to a more M.R style fin or maybe a smaller keel.
Any ideas,help info would be great thanks.
Paul.

He's made them himself. Can see the cut marks at the base of the tab.

Why have you two different size fins for a twin?
Ah, I see you bought it off ebay judging by a photo I found. So I guess the small fin is for comparison. The fins don't look too bad to me??? :dontknow:

PS maybe the tabs are too far forward, making the fins too far back.

Sorry mate forgot to say the smaller is an old g5 in my post,the bigger fin is much bigger then the M.R's i had a while back.They have a ton of sweep?i think it is or angle ,they just feel wrong,and as the above posts have said could be home made which could be a problem aswell if they aint done well!

Trying to make a kingfish loose and slidey could be a bit of an ask due to its fishes twin pin tail.
The wide swallow acts like two pin tails so giving it hold.
Try the MRs as Prj suggests.
If you want more release off your top turns try a True Ames CI twin (Machado) set.
You'll still get the drive from the wide bases.
