I bought this 1964 Hydrodyne 1500 two years ago and am trying to get it ready for the water this summer. The boat looks worse than it actually is. There are two areas that I am not sure what to do about. The first one is common to many posters of the forum. I have a fifty-cent sized hole in the fiberglass floor back near the stern (red circle in attached pic). The hole is directly over some wood (a stringer I assume) and the wood is wet and slightly spongy (although I can feel some hard areas to it). What should I do here? I have seen where others have completely ripped out the floor and replaced everything. I am not opposed to this, but would like to use the boat this summer and then take it apart in the fall\winter. should I just place a fiberglass patch over the hole for now? Also, I saw someone mention that there is a difference in floor construction in pre-1970 boats. Not sure if it applies to this boat or not. The second concern is that there is small hole in the front floor area - second pic, red circle - (not sure what the correct term is here) that does not seem to be original. Seems like a previous owners hack to let water drain in\out of someplace. should I be worried that there is more rotten stuff under the floor? Third (and last) item: There is no bilge. The floor runs back to the stern and drain hole is even with the floor. Is this normal?
