Hi there, any tips on how to support a 28ft fin keel yacht with wooden logs ? Ive always used a trailer before but it got stolen and sold for scrap ! Thanks in advance
I know lots of boats are stored with timber chocks, but it's not an ideal way of doing it, a cradle is much safer. Will this be in a boatyard? If so, pay the yard to do it. Then, if it falls over, at least you'll have a chance of claiming.
Cradle is much safer, and many yards will not use anything else because their insurers insist.
We had our One Design fall over when laid up with timber props, MDL mainly used them at that time, it was on grass and wind was up to F9/10 at the time.
Fortunately it was the yard who had done the laying up and after some argy-bargy their insurers had to pay in full for the repairs.
Interestingly the next week the yard staff were seen furiously nailing cross bracing to all the timber propped yachts, and the next winter their policy had changed to cradles only.
If it is on your own land and you want to go down this route make sure you have plenty of decent size props to spread the load, and preferably some under the bow and stern to avoid hogging if it is a wooden yacht. You will need wedges as well to get the props tight. Finally make sure that at least 2 pairs of props are lashed to each other under the keel, use a spanish windlass to get the lashing really tight.
Basically, timbers are wedged in the places that the legs of a cradle would be and then battens are nailed on, cross-bracing between them, to prevent them moving. Many people are successful at this, some get it wrong and the boat falls over!
Alternatively, I reckon you can make a bespoke cradle from scaffolding components for around £200. I've done this twice and had no problems with them.
Hi, a couple of railway sleepers under the fin, vertical supports fore and aft. 4 x 4 oak timbers, at least four down each side. 18mm ply squares with carpet against the hull. Dig out the ground for the side supports. If you are on concrete, you need to drill and bolt chocks to the concrete to prevent the bottom ends of the side supports from sliding out. Add double ropes from side to side and tighten the side supports with spanish windless.
Logs are fine, no need for expensive cradles!! BUT the logs must be braced so that the cannot fall out, the bracing can just be light timber 2x1 even. Try to brace across as well as along.
