We've got a slip in Grand Haven at the Wharf / Yacht Club which we love.

However, we're dealing with the Grand River which even after only a couple days leaves the bottom a bit "fuzzy". We had an issue with the trailer last year and after 2 weeks in the slip we literally had fur growing on the bottom. Even after using a heated pressure washer at the ramp, the bottom was still so gooked it took me several hours, a case of beer, and almost a gallon of bio-kleen to get her clean.

So here's my question:

Has anyone used a bubbler in the summer to keep the gook from growing on the hull ? Or at least slow down the process ?

I would think it would at least help ?

Any thoughts ?

Thanks & Cheers

Bubbler isn't going to help, the water has nutrients, the sun comes out, and viola you have growth.
You can hire a diver, but you'll still have to pull and get acid washed once in July an once in August if you want to stay bright white.
Lift?

Manning is building me a lift right now but when we overnight - which is a lot - the boat will be floating.

I was thinking if we could keep the water moving it would at least slow the growth process down.

I spoke with a guy the other day who is into aquariums and he thought a bubbler might turn out to be counterproductive since it would effectively be oxygenating the area.

Thanks for the thought & just FYI if you're slipping in GH without bottom paint it's going to require washing (much) more often than only once a month.

We were a day or 2 over 2 weeks while we were having the trailer welded and it was Ugly. I have pics but I'm embarrassed to put 'em up.

Agreed with the more than once a month, I was suggesting having a diver clean the bottom during the weeks between getting hauled. I have a diver clean the waterline on my boat when I can't get to it, he maintains a couple of sailboats with no bottom paint.
The lift will be great, solves a lot of issues.
I'm in Lake Mac, we get the same aggressive growth, especially in the warmest water of July-Sept.

At least your not dealing with barnacles. Where my buddy keeps his Silverton cruiser in Fort Myers you can almost hear them growing on the boat it's so bad.

Buy yourself a good thick wetsuit and hood, mask, fins and a small dive hookah and dive on it out in Lake Michigan every couple weeks or a brush on a handle and stand on the sandbar would get most of it off.

At least you don't' have to worry about bumping into sharks. I'm a diver and do a lot spear fishing in the Gulf , but there is no way you would catch me in the water at those Marinas in Florida where you can't see your hand in front of your face and neither can the big Bullshark.
