Hello All,<br />I'm new to this site and have questions about a boat I just got.It is a 1958 glasspar Avalon in what seems to be very good shape for it's age. My son and I can walk around in the boat and the floor does not seem to sag or feel soft in any places. I haven't had it in the water yet because the padding under the seats was rotten and we wanted to fix the seats first.This is my question, is there any way I can check the underfloor structure,wood and such to make sure there is no rotten places before I take my family out on the lake.I've seen many postings & pics of many boats much newer than my 1958 with the transoms and floors removed because of rotten wood and fiberglass. I'm new to boating and just want to concentrate on getting experience launching, piloting and tralering and not wonder if this boat is safe!I love this boat and plan on completly restoring it, but want to get it in the water a few times before winter hits here in Ohio.Any advice would be greatly appreciated. Thanks Jim L.
