Simple question, but still a question:keel repair
 
Hi,
Purchased a pearson 31 this fall, have not sailed her yet. There was no wood placed under the keel on the cradle, and the very bottom (of the keel) has some damage that I can see. I would like to fiberglass it this spring but not sure what the best approach to reach the bottom of the keel would be? The boat needs to be raised to access the damage, that is for sure. Do I ask the marina (skipper buds) if I they can lift it and leave it on the sling over-night for me? I was thinking maybe they could leave it in the sling for me the night before launch and I could repair it then?
Any suggestions for a novice would be appreciated!
Thanks!
Chris

It is common to request that you be the last lift of the day and leave her in the slings overnight. Essential if the boat is made of wood and needs the wood to swell overnight.

If you are going to do a repair that will last, it'll take more than one night to do. Typically you'll want three layers of glass or epoxy, followed by two paint, depending on just what you are fixing. You should allow a week do do something like that, as the weather can matter also.

You probably should have the boat reblocked so you can get at what you need to access.

I thought Pearson 31 had a bolt-on keel? Is it an encapsulated keel?

Thanks for the responses! If I have it re-blocked, can the boat be supported with nothing under the keel?
Thanks again!

I'm with brak on this one. Pretty sure its a bolt-on keel. Any repair is more likely some filling and fairing with epoxy, not fiberglass.

I would definitely want the boat supported by the keel. The stands are for balance. I had a similar issue a couple years ago. I had my yard crew block the front and back of the keel the first year. They used 4 x 4s to give me a little room. Then the next year, I had them block the center. It worked pretty well but wasn't an instant fix. You can't do it overnight.

I'd be very nervous having the boat supported only by the stands. The pressure if supporting the full weight of the hull on those small pads...ouch...I am no marine architect, but I am guessing the hull wasn't designed to take that kind of pressure. I'd hate to see massive dimples on the sides when you launched her!

I have a similar problem on my Endeavour 32. Unfortunatley it is resting in my driveway far from a travel lift. I hope to lift it slightly to remove some of the cradle crossmembers. I'll have to do this before launch this year but it will take more than one movement of the beams to complete the job. Any suggestions?

The boat hull has no problem supporting its keel, in or out of water. OTOH, the yard should be smart enough to know where to place the stands along the hull. Stands should go under bulkheads or other internal support parts and should number about four stands per side for this operation.
When our keel was dropped for a re-bed they supported it with lots of stands. No hull problems at all.
