Got in from a surf today and realised one of my outside fins was missing
Cheesed off as it was a carbon set from Shapers ,
On closer inspection i found the fin was missing due to the fact that the round bar that locks the fin in at the opposite end to the grub Allen screw was ripped out
Dont no how I did it but my last wave went all the way to the beach and I near stepped off on the sand 
My dilemma is to pay big bucks and have a new fin box put in or as the fins are a good tight fit just make sure the grub screw is done up nice and tight or some temp silicon so in long term I could still remove it
The board is a Hobie Colin McPhilips 8, 4 "
Any suggestions guys
I am not sure if it is possible but maybe a grub screw on both ends?
or a cover plate over the top on the end that used to have the bar?
A fin box replacement will cost you between 50 and 100 bucks depending on who you know. Worth it in my book.
Yes, I am happy to have a go at fixing most things, but this is one where you need to replace the box.
The Futures fins slot closely onto the rear tab and into the box. When I have done home surgery resetting these boxes, all you need to do is spill a couple of drops of resin into them, particularly around the rear tab, and the fin won't fit. Retro fitting that tab without removing the box anyway would be impossible. If you try, you are likely to loose another expensive fin.
New box time!

The most common cause to fins not fitting in futures. 
Futures - I PERSONALLY think they are the weakest link in fin systems
Lost a few in my old PSH - stamps Quad sides just dropped out - maybe the leggie pulled on them - not sure
- F'n useless and expensive replacing fins - and I am not alone
Funny I have had heaps of short boards and a few SUPS with FCS and never lost one the 25 odd years since they stopped glassing fins in (broke on one a reef but that doesn't count).
A systems design is only as good as its failures
