Hi Dave,
I had the same challenge when
on the hard at PSS Satun in December. The
boat was supported on its two
keel bases and what we did was raise one end of the
keel at a time, with a supported hydraulic jack, just enough to get a small
paint roller in and then lowered it on a hard
wood board. Effectively twisting the boat every so slightly - but it does this in seas so no worry there. However I still didn't get 100% coverage but near enough.
Its a bit worrisome though. You have 16Te resting on two keels of approx 1m square each. Thats a lot of weight on a small area. I think the balance of the boat is good, its been designed for it, but suggest you keep your
water and
fuel tanks low and the clean and paint it as quick as possible.
Note that
Lagoon recommends that the a 100% keel base is to be supported at all times - obviously.
