Guess I should have expected that each maintenance/upgrade would lead to a whole different set of problems. Wanted to get an evaluation of the rigging on my 30 yr old Pearson 26 (certain that it was all OEM.) Was told all shrouds and stays were so old and stretched they could not be tuned anymore, making the mast structurally unstable and dangerous. In order to replace, the mast would have to be stepped. When stepped, it was discovered that the bolts holding the mast step to the deck were rusted and needed rebedding. Now it turns out the water that caused said rusting has ruined the structural wood frame that supports the mast from inside the cabin (sorry, I don't know what the proper name for this is; to me, it would be the door jam that separates the main salon from the head.) I can't even get a reasonable estimate on how much this repair will cost until someone goes below and removes what't there to fully assess the situation. The marina tells me they have no capacity at this time go in and do the work (if in fact they knew what needed to be done.I shudder to think what else is lurking below the surface. I thought I had a pretty decent boat last season but am getting discouraged with what I'll apparently have to invest this year to use it again. I'd seriously dislike spending the whole summer on the hard trying to make her seaworthy if every layer of the onion portends doom.Any advice on when is a good time to stop throwing good money after bad? I paid $5K for her and have spent an additional $3K so far this year. I'd be happy to spend another $2K to get her on the water, if I could feel secure that I wouldn't have to spend that kind of money every year on a basically depreciated commodity.
