I Elmoed another fin yesterday. That's the second this year. I'm moved once again to consider a folding fin system and to moan about the piss poor design of current fin systems.
Power Box is piss poor. Classic box is adaptable and nicely forgiving. Trim box is piss poor and happily obsolete. For strength and adaptability for folding Tuttle wins hands down.
I thought the whole point of those brass threaded dowel inserts (sorry don't know name) was to strip so the bolts pulled out? Obviously not.
I believe you could just make the threads in the brass fitting(s) weaker by running the right size drill through them to take some of the thread surface off. Obviously trial and error, so it would pay to have some spares before attempting this. Maybe you could modify the fin so you can thread some fishing line through the bolt hole and tie it to the fin, so when you lose the fin, it is still tied to somewhere on the board like a washer in the bolt hole. Just some thoughts.
I've given it some thought in the past, but as I haven't lost a fin yet (just a matter of time), I won't have a passion for finding a solution like you. Please post if you work something out.
This defininately qualifies as No;2
I lost a fin a few weeks ago at low speed when I hit some crap submerged. Fancy an F2 not having a tuttle box.....the fin tore above the brass threaded gizmo.
There is hardly any material above this so it ripped straight out .I guess it can be argued that at least the box did'nt get busted ,but fins that become unrecoverable get a bit expensive too when it was only just a bit more than a bump.
