Help - Need Repair Recco

is your stringer ok ?

 

If that's a buckle... and it appears to be from the pic... it's not your typical ding repair. That beefy stringer's what kept it from snapping. If the stringer's not compromised, and if there are no stress cracks on the other side, you might get away with cutting out the damaged glass and just patching with several layers of cloth. If there's more damage than meets the eye, you should strip off a wide panel on either side of the crack and reglass, and you might even have to reinforce the stringer... I use fin roving/rope, but others use wood.

 

there's some color around the crack, not sure if water got to the foam or sand. the resin that goes over will be clear like glass. the more time and effort the better the results. quick fixes show.

 

If you've been riding it, and it hasn't gotten worse, I'd say there may be no need to cut away any glass. If I saw it in person, I might have more solid plan, but from the pic, and what you're saying, I'd say... just sand it heavily. I'd machine sand it with a 6" hard pad, but you could use an orbital or disk... whatever you can get your hands on. Sand the crack and the area around it right down to the weave... maybe even go through the first layer of glass right at the crack. Sand an area about 4-6" on either side of the damage, mask off the unsanded surface with tape, and laminate with 6oz cloth. I'd do about a 6" strip right over the crack, then a 8-10" strip over that, then a 10-12" strip over that. Fair the edges, hotcoat, sand.
