Bottom painting

[togzilla]

Bought a 2020 SH boat last and after a long winter I’m ready to get her back in her slip after I bottom paint it. I keep the boat in Barnegat Light and the water there is much different then Raritan Bay. I have a single season Sea Hawk ablative paint on their now from the previous marina and looking to put a multi-season paint on there. Seems like everyone has their own opinion on paint and I’m looking at Sea Hawk Cukote, Interlux CSC and also West Marine brand (Petit just with West Marine branding). I’ve been told 2 coats of paint but then the maintenance guy at my marina says 1 is enough since it is going over a previous base. Any thoughts on this and what have your experiences been? Boat is a 25 ft SH center console. Would a gallon be enough for one coat?
