Guys,
I'm going off on a tangent here, but I would like to ad my thoughts about boats on the hard for extended time. I don't know of any fellow boaters with this problem thus far.
Some years ago, I pulled my 1980 C30 boat for a simple(?) bottom job. I discovered I had a huge problem with blisters. In the era when the boat was made (1980 in Calif.), laying fiberglass & quality control were distant cousins back then.
I discovered 118 blisters, most of which were 4" or more in length with widths of 3" or more. I decided to use the West System & do it myself. I did this for the next 4 weeks, in HOT Florida August conditions; highs in the 90's under a brutal sun. There were other problems to force me to haulout then, but's another story.
Here's the problem I encountered while on stands. Deck water drainage had been no problem, it flowed to the drain scupper (if this is the correct term) indent in the toe rail and overboard. When the boat was re-splashed however, it became apparent that the water no longer drained as normal, but now would pool up on deck four feet forward of the scupper/drain area both port & stbd. sides.
I have to assume that that under hot conditions, the hull had sagged slightly. I suspect that the stands used may have been spaced too far apart (or not enough of em), and the heat & weight of the boat over 4 weeks led to this. Add to this the forces of rigging tension, and it's now permanent.
So, you guys having to spend months on the hard, please make sure the yard uses a few extra stands spaced properly so you never have this problem.
My tangent here is done.......
