i redid the bow piece on mine.use the old piece as a pattern.it works great.to put the carpet on use a waterproof glue and use marine grade carpet.lowes,home depot sells it.stainless screws,#14 phillips heads are the best.pilot holes also would help.remember where the old screws are and try not to make it in the same holes.if possible,get some clear tape and tape the stringers with it.it will stop corosion of them.
lay the carpet over the wood,cut it to length and width and shape.lay down a good layer of glue,lay the carpet down,use stainless staples,1/4" ones down to hold it.glue the edges,fold it over,then staple it down.leave the back open for drainage.let it sit overnight at least before screwing it down.
while youre in there,check the foam,make sure its not water soaked.if it is remove and replace.do it now while its easier.any upgrades can be done now.check the rivets in the stringers now.if you have access to them,replace them now with 1/4"ones,save the headache.take and make sure the bildge drains are open all the way through,remove the fuel tank and make sure they are open all the way through.clean out the fuel tank while its out.
