Undercoat Paint / Hull Growth

[Dshriber]

I keep my boat in the water from May through october. I am in a freshwater river that gets a large amount of growth. It slows down the boat by at least 5MPH. My marina isn't set up that great to pull it and pressure wash. I do it about once or twice a season. I have friends that mention they have a special paint on their hull that eliminates growth. Does anyone have any thoughts on this product for jet boats?

Thanks!

On these boats if I were to choose to use antifouling bottom paint, I would use a hard vs ablative (soft) bottom paint. I did not paint my Yamahas' bottom, I just scrubbed it at the beach a couple of times during summer and acid washed it in the fall.
I say hard paint because of the bunks vs rollers on the trailer could wear away the paint prematurely. We were at a slip from mid May to mid October.

On my sailboats we used ablative (soft) bottom paint. They still need to be pressure washed in the fall.

I would not bottom paint your boat.

Just pull it out however often is needed and take it to a coin operated car wash to clean the bottom, if you do it frequently enough it will be a very quick affair.

This is the acid wash solution I use at the end of the season…Anytime you use an acid wash proper PPE (personal protective equipment) is essential, safety glasses, nitrile or platex style gloves, N95 mask at minimum, long sleeves, pants, close toed shoes. When you get done take off the long sleeves and pants and wash them. Keep other people, kids, pets and idiots away from the area while you use this. Rinse with copious amounts of water.

I'm in Michigan and I used to bottom paint all my fiberglass boats that sat from May to October in the water. I would put a coat of epoxy down in a different color of the bottom paint, that way when it got down to the epoxy base coat, I knew it was time to touch it up (here are a couple examples). But those were deep water Fishing boats we rarely took to the sand bar to hit the bottom up to remove the growth over the summer months. The bottom paint always took 5+mph out of my top end speed, so in the latter years of fiberglass boat ownership, I just made it a point to hit a sandbar for 30 minutes as much as I could to scrub the bottom with a sponge or yellow scotchbrite scrub pad (the yellow soft side, not the green harsh side)

With the Yamaha, we are always at the sand bar every trip and scrub the bottom while we're there with the Ryobi submersible power scrubber and when it comes to fall haul out, the scum line isn't that bad. A brief hit with the the pressure washer, Ryobi scrubber, and star brite instant hull cleaner, it has come out just as clean as it was when new

It also helps to get a good coat of marine spray on surface prep cleaner and spray on wax on the hull in the spring to keep the growth from sticking to the bottom during the season.
