Have you considered that perhaps Titanic broke in half when colliding with the ocean floor ? talking of twaddle, accident pathologists look to separation of the remnants to help determine the point at which a hull was broken above the sea floor. You could do worse than review the hull separation of the Titanic remnants. Brian W |

It has been assumed that you wish to do this to make painting (or something similar) easier. If this is the case, how are you going to work on the bottom of the keel? If you have to do the bottom in a different stage anyway, why not use a more conventional method (i.e. moving stands etc.) for the work? The plan is to block of the foot of the keel and secure ropes from the top of the mast out to the . . . plus mast and a moderate keel that is level bottom. All thoughts very much appreciated I have not seen or done or attempted any thing like this before. I dunno but I suspect that many boats are ok being supported only by the weight being on their keels.

Supporting a boat by its mast.
I have done the osmosis using long wooden wedges under the rubbing strake,
seemed very safe i will look for photos! "beryl george" wrote in message ... From other members of the news group thoughts and experience am I missing something or is this something that can be carried out providing there is care with a reasonable degree of ease and safety. The plan is to block of the foot of the keel and secure ropes from the top of the mast out to the sides at about 45 degrees to hold the boat upright so the support pads on the wintering cradle can be lowered to allow unhindered access to apply the 4 plus coats of epoxy coating to the under sides. Or has anyone any other suggestions of a better way to support the boat whilst it is epoxied. The boat weight is around 10 ton with a 50 foot plus mast and a moderate keel that is level bottom. All thoughts very much appreciated I have not seen or done or attempted any thing like this before. |
