Re: Clean bottom how much?

Hey,

Here on the north shore of Long Island (Mt. Sinai) it costs about $100 to get a 35' fin keel boat scrubbed. I clean mine myself (mask and snorkel) every month in the summer. I keep the paint in good condition so it's not too difficult to clean.

The boat I race on gets the bottom cleaned every other week.

Barry

We pay $100 in March then $25 a month for the next 7 months. have Ultima 60 paint which has worked great. Used to use Micron Extra which worked well also. I am on the Chessie

Re: Clean bottom how much?

Here in western LI Sound bottom is cleaned approx. every 3 weeks
@ $60. for 30fter.
My previous bottom cleaner would charge less per foot for
a cleaning every 2 weeks than he would if he were cleaning once a month.

Re: Clean bottom how much?

$2 to $3 per foot is going rate. Be wary of cheap vendors that could really ruin your bottom paint. Also be wary that it could be you that is ruining your friends bottom paint, if you're not familiar with the right techniques. They won't know till they haul, but the few bucks wouldn't be worth it.

Re: Clean bottom how much?

Remember the "Good ol Days"? TBT! I still have a couple of quarts around someplace. It sure kept things from growing on the hull, and in the harbor! Yikes! Then there was "The Bag". You parked your boat at its slip in a big plastic bag with a floating rim. The floats got pushed down with a boat hook as you entered or left. While the boat was parked you dumped a gallon of Clorox into the bag inside the floats and nothing alive inside the plastic barrier survived. Ah Lake Pontchartrain in the 60s. That body of water grows stuff!

Keeping the hull clean is a day's work even if you just have to wait for someone else to get it done. I am hoping to have a breasting pier set up ready for next season. With 10' of tide I would like to be able to stand and clean it without my scuba gear. Our harbor is a high growth spot and I can watch the rpms drop as the weeks go by.

Re: Clean bottom how much?

I apply one fresh top coat every season. It keeps growth down and I can easily get away with a hull cleaning every 2 to 3 months, sometimes 4. Granted, we are in a relatively lower growth region than southern climates. I went one full season from April 1 to Oct 31 with zero cleaning on a fresh paint job. It was slimy, but zero hard growth (other than the prop and shaft and it did kill one knot of boat speed by the end of the season). Long story why this happened, it wasn't planned.

If you're not racing, I don't think a little slime makes much practical difference. A full season's worth does. Otherwise, poor sail trim and blown sails are much more detrimental to speed than a couple of months worth of growth. FastBottoms, who posts here, has made a good argument that infrequent cleanings require more abrasive tools, which can reduce the lifespan of your paint. I'm sure that is true, unless you top coat every year anyway.

My biggest gripe with slime? It looks terrible when you're heeled over and blowing past another boat.

Re: Clean bottom how much?

Gee, it never occurred to me that there might be a right and a wrong way to clean the bottom. As with Minne I'm also in the Northeast, and bottom growth is not usually a significant problem. I use an ablative (Micron CSC) and a couple times during the summer I'll take bristled brush at the end of a telescoping handle typically used for cleaning decks and brush the slime off the hull. Usually the only place that needs to be cleaned is near the water line. In 11 years there was only one year that I had some barnicle growth on the bottom. (The prop is another story. Lots of barnicles there.)

The boat gets sailed at least two days a week and sits on a mooring.

So I guess what should I be using to clean the bottom? And what is the proper technique. Or are you guys getting me to overthink this?

Re: Clean bottom how much?

I clean the bottom before every race. Once a week or once every two weeks, whenever racing is. It's a 25 footer, so no real need to pay someone else 75-100 to clean it. I did that once, and they did a horrible job. My next $100 went to a wetsuit and flippers.
I've never been happier knowing it's done right.

Edit: boat gets new paint every season. Solomons MD.

You want to use the softest media that will remove the growth. A piece of old carpet works low growth. The least abrasive scotch pad is next. Then work your way up through more coarse pads until you can get the job done.

Going at it with a bristle brush or wire brush just has to remove paint too, especially if ablative.
