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. However, one thing that strikes me
is that when the Titanic sank, she was initially in one piece and only
broke in half when the upward force of the water was removed from her
entire hull when she was submerged. She was designed to be supported
evenly all over by the water, once this support was removed, she broke
in half. Does this apply?, probably not.

Very likely NOT.

This is getting off-topic, but twaddle should be promptly despatched...

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.

I have done the osmosis using long wooden wedges under the rubbing strake,
seemed very safe i will look for photos!

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.

You may want to have multiple sets of ropes, one set at the top and one
set at the spreaders, kind of like the way radio towers are supported at
multiple levels.


Or like how a mast is secured to a boat?

Exactly. The point would be to have a set of ropes everywhere shrouds
attach to the mast and tension then the same. That kind of arrangement
should be easily be strong enough to keep the boat upright.

I seem to recall that the original poster intended to secure these ropes to
other peoples' cradles. Would that color your opinion?
