Afternoon,

Just thought I'd share my vid of starting to remove the antifouling.

Sandblasting seems to work really well, the epoxy primer is a lot harder than the antifoul. Going to let it dry for a month before coating up with more primer. The keels will be treated immediately with Fertan then allowed to breath for a month before primer.

Tricky bit will be lifting the boat off the trailer. Not sure if I should make a gantry and winch it up or support the boat on a wooden cradle then dig the trailer out... answers on a postcard.

If you insist!

For acces to the bottom of the keels I might suggest you tilt the trailer using jacks either front or back. Then pack a support under the hull such that the trailer can be returned to level leaving the hull supported above the trailer at one end. Hence hopefully the ends of the keel clear to clean and paint. You can do the same at the other end either at the same time or after finishing the first end. Doing both ends at once will require more supports and then also supports to stop the boat rolling. be very careful of the integrity of the supports. Especially when you have your hands under the keel. As Vic alluded to it much depends on the total weight. good luck olewill
 
Well done Vic and top marks for effort!

Thanks Will, was thinking about that one, it'd be fine for the back but would need a bridge constructing to support the front to allow the trailer to come out the way. could possibly get some silly angles if leaving the trailer there and still having room to work effectively

I'm assuming the boat would need a cradle to the profile of the hull when not supported by the keels? Point loading would probably stress the hull. This got me considering some form of crane, perhaps just for the front and we can winch it up on straps.

I have a 2 1/2 tonne digger, 1 tonne digger, forklift capable of 1 1/2 tonnes, plenty of winching options and the neighbours forklift may be available too... Concreting posts in doesn't phase me nor does welding or fabrication. There's a dozen ways of lifting/getting off the trailer, I guess the thing is how to support it once it's off. Answers on a billboard this time please....

Yes I understand he problem at the front with the trailer under the bow. You will need to build a bridge arrangement from each side of the trailer to support the bow .
Alternatives are a gantree built above the deck from which you hang webbing under the bow section. (or stern or both). If it is wide enough you may be able to wheel the trailer right out from under the keels. However this gantry will involve some fairly hefty steel up rights and cross members which will have to be stayed to keep them vertical or stayed to front and back. Just don't get under the keels unless you are really sure of the structure. good luck olewill
 
Thanks Will,

That's pretty much where I was going, could leave it hanging for weeks and it'd leave me lifting options in the future, If needed.

Talking with my neighbour and we're thinking that we may be able to park the forks at each side and 2 slings fore and aft of the keels to lift above the coach roof. We won't be able to move it or hold it there for long so it'd just be a case of wheeling the trailer out and supporting the boat on timber on concrete blocks in 2 thin points on the keels. I'd have to jack it up and shift the supports to complete the paint job but I think it's worth a go. Biggest 'if would be whether my forks are strong enough... might be best craning the motor out 1st, another job that's got to be done anyway.
Got a few weeks to mull it over either way but I'll post back when done.
