It's on the rail of my new Manta 69 - just a hole about 1cm deep and about 5 cm long with bits of carbon and stuff hanging out. It's going to be bloody ugly when it's fixed as it's right in the fancy gold paint.
1cm deep x 5cm long is nothing if it is 0.5mm wide (like a knife cut) and is on the rail near the nose where there is no stress. I'd just bog it with epoxy and q-cell or talcum powder or sawdust even, as it is not a structural fault. Worry about the paint later.
However if it is 1cm deep x 5cm long, and is a depressed fracture say 2 - 5cm wide and it is on the rail between the fin box and the mast track, well that is a bit different. That may cause weakness.....Then you need a good repair, but anyone who can vac bag d'cell and glass properly will be able to help. Decrepit or Rider5 will sort you out
Steve is currently In Europe (Greece I Thunk) having a go at a couple of PWA events< don't think he has email anyway, If you can get hold of Slowie he may be able to pass the message on.
i repair boards in Newcastle, been doing it for a few years now, i'm moving to Perth next weekend, not sure if i'll be doing it over there as i prob won't have a shed to work in for a while, if anyone gets desperate for a repair i may be able to help out. can even get them back to almost factory finish depending on the complexity of the graphics..
