Why not ask the guys who sail there all year round.
They will tell you what they use :o

no different from any other water.........I sail solely on salt water at Fleetwood.............with all my grp hulls.

etching primer..............then filler primer ..............then normal primer, white or grey depending on top colour............and them my top gloss coats..............all spray paints from Halfords..............never had any problems.

run it up in the bath afterwards otherwise the shafts etc will corrode this also gets rid of the salt crystals which could leave a mark.  :-))

Another thought is: after your run on the pond and you have your boat back on the stand run the motors in reverse for a few seconds to remove any water that crept in the shaft tubes. Take a bottle of tap water with you and wash down the hull, props, rudders etc. Then lube the shafts. Most prop shafts these days are stainless steel so rust won't be a problem although salt build up may. Take care of the rudder shafts as well as they may not be stainless, lube them as well.
