bottom paint removal questions lagoon 380


 

we are considering having the surface renewed on our year lagoon 380. ? St John Boat Company Jacksonville, Florida has invested in sponge blasting equipment which is 'greener' for the environment and gentler to the hull. ?

two questions
1. They price on square footage, so what is the surface area of the painted surface of a lagoon 380's' bottom?
2. What should we be looking / asking for to help get a good estimate on a 18 year old boat?

Moisture test around your thru hulls.?

If water line thru hulls are the old plastic ones replace with the newer more reliable versions.?

I take it by renewing the surface you mean to blast off all the antifouling down to the fibreglass substrate. An epoxy coating should then be applied. It is then a good idea to apply the antifouling undercoat when the epoxy is a little bit past “tacky” that will guarantee good adhesion. Replacing the thru hull fittings if they have not been replaced in the past 7 years is good advice.

I think the underwater area is 44 sqr m, approx 475 sqr ft.
Mine is probably a bit more as I had the antifouling line raised a couple of inches because she sits low in the water due to all the extra weight she has accumulated over the years (a bit like me really)

380 s2.?yard 2 years ago used 3 gallons of?Sea Hawk Biocop TF . I am actually surprised it was 3 gallons, I have heard others say 2 gallons... I am in the Northeast, boat left in the water over the winter. Had a diver clean the bottom a week ago and said it looked 'really' good for it's second year, and suggests that I use this paint again. Will do bottom next may after 2.5 years. As others have said, do the sail drives with the specialty stuff! No idea what the surface area of the paintable bottom is.?
