Re: What's with the slime??

No, it is not "news" to me. But now I am rethinking spending the extra 100 bucks to "Control" slime. Next year it will just be the first and only $100 that I spend. I was about to spend $100 a gallon until I saw what the $230 a gallon stuff claimed to do. I'm sure the warm water is a contributing factor to the rapid growth and nothing is going to stop the slime. I must say the hour I spent in the water under the boat scrubbing was a fantastic cardio work out. Hey, maybe I'll smear the stuff they put inside Twinkies on the hull. No way anything could live or grow on that.

Re: What's with the slime??

Micron Extra and Micron CSC also do a better job of retarding slime growth if you sail the boat. They are least effective at controlling growth when the boat sits idle for long periods of time.

I'm in the Chesapeake Bay, which is a high-fouling area and even though my hull grows slime, I can either "sail it off" or if I choose to get into the water, a soft car-wash mitt wipes it right off. I try to be very gentle so as not to shorten the life of the paint.

Hard growth? Not a sign of it. It's been one year so far. I figure I'll get another year, then re-paint.

Re: What's with the slime??

The boat is sailed at least 3 days a week and raced on Wednesdays. For some that's a lot, but there are 3 partners with different schedules. Mondays and Tuesdays I'm out there practically alone. Today I stole a few hours before work and it was a circus on the river. Albeit a windy circus. 2 weeks we're heading for MV.
We are up the Hudson river far enough where there has been no sign of barnacles, only the DAMN SLIME!! Argh!! Before the last race a buddy was shocked when he saw me roll off the dock with a mask, regulator and tank. 1 hour is all it took. What could I charge my dock mates???

Yes, your paint is shot. Most anti fouling paints (when in good condition) will work very well against higher forms of fouling organisms (like barnacles.) They perform less well against lower forms (like algae) which is why the "anti slime" paint formulations came into being and are so popular. But the bottom line is; if you have a serious barnacle infestation on your hull, you need new paint.

At this point, anything but a new bottom is just a bandaid. But consider giving a local hull cleaner some work before you haul.

For boats that live in the water year round, typically you can expect to get 2-3 years out of a quality anti fouling paint, whether it is an abaltive or hard product. There are exceptions but nothing is going to last longer than that. Talking about actual paint products now, not copper-loaded epoxies like Coppercoat etc.

The manufacturers do like to sell "multi-season" ablatives to those of you folks with short sailing seasons. I will not speak to their effectiveness in this regard, having no experience with boats that come out of the water for the winter. But it is true that ablatives can withstand prolonged periods out of the water while hard paints cannot.

It never ceases to amaze me how many customers call me at some point during the spring or summer, claiming that I could not have cleaned their boat two weeks previously (as indicated by the invoice they had received) because the fouling growth they were looking at could not possibly have grown in that time. I understand that part of the hull cleaner's job should be to educate the boat owner about the realities of the fouling progression, but man, sometimes I wonder!

Whatever the market will bear. $2-$3/foot is typical. But unless you really need the money, you are only helping the competition, no?

Re: What's with the slime??

Be careful on charging people. Most marinas will want too see proof of insurance as soon as you set foot under a boat that isnt yours.

Re: What's with the slime??

Slime has always been a fact of life around here, which is why every racer has a bottom brush. It takes about 15 minutes to give the bottom a quick rub before you leave the dock. Not a big deal really! some guys use a bottom "flosser" which is also very effective.

Besides, slime feels pretty slippery...who is to say it isn't fast?

Re: What's with the slime??

I have the yard apply one top coat of Petit Vivid each year, which costs around $1500. A hull diver charges me $150 to clean her, which I only do once or twice per year. I will bet I would be well ahead of the game by skipping a year and cleaning every 6 weeks. But, I do like that new look of a top coat.

For me, it's a hassle to have her cleaned, as the marina will not allow anyone in the water and I have to use my time aboard to move her for cleaning. I'm not sure if that is for safety reasons or to keep the extra copper from being added to the water from the scrubbing. I think it's the latter.

New England marinas are beginning to be required to install water reclamation systems under boats they power wash upon hauling, but can defer it if they have some mitigating practices. The requirement seems to be fairly subjective, as best i can tell. I will bet that agreeing not to scrub boats in the water is their "settlement", for now. I know of one New England marina that requires all newly painted boats to use environmentally friendly paint. I know of another that will not power wash ashore at all. You must have your hull cleaned in the Bay before hauling.

Once again, it is all environmentalist masterbation. I can move a few hundred yards to a mooring or drop the hook in the Bay and scrub away. Idiots.
