I got news for you- hull cleaning does happen on a regular basis. Here in California, boats are cleaned typically 4 to 15 times a year, depending on location. They haven't yet invented an anti fouling paint that eliminates fouling in regions of moderate or high fouling. (Well, OK, they have, but it's illegal now ) But you're right, we (as boaters) should all be lobbying for non-toxic alternatives to anti fouling paint. They already exist, but until copper is banned from use, they will never see a big share of the recreational boating market. They tend to be more expensive, more difficult to apply and less effective than traditional, copper-based paints.

The Brits do this all the time. They call it drying out. I think mostly make thier own legs but they're pretty robust devices. You may find some info at the "Practical Boat Owner" website. They had an thorough article on the setps for drying out by leaning up agianst pilings in thier October '09 issue. I think this is a lot easier than using legs, safer too. You however need a pretty large tide range to do this. Here in the Pacific Northwest we have about 9 ft. + tides and marinas have grids for doing this. It's some beams a few feet above the bottom alongside the warf. You tie up and the boat settles out on the beams as the tide goes away. We used them all the time however recently grids are getting harder to find due to environmental concerns over scraping off bottom paint at the site. Finding some pilings is still easy. My experience was that it was important to know where the flat part of your keel was for positioning over the grid, tie the boat up so that it leans into the dock or piling as the water receeds, you can't walk too far fore or aft from the keel unlesss the ends are also supported, have a way to plug up holes when the tide comes back as you may run into snags in you project (experience here), you'll need a ladder.

Walt is on the right track.

If you want legs, the only commercially available ones I know of are Yacht Cradles - Yacht Legs - Boat Stands - For Sale - The Yacht Leg & Cradle Company . In many areas of substantial tides there are seawalls or docks you can tie up to at high tide that dry out at low tide.

Careening per se means anchoring or otherwise tying up the boat so it settles on its side when the tide goes out. That works best where there is an area of soft bottom where the bottom is relatively flat and dries at low tide.

It all works, recognizing the quite appropriate comments above about environmental impact.

Well it's okay, it happened outside the environment. The front fell off.

Is that typical?

Cardboard's out.

I thought they towed it outside the environment after the bow fell off.

Great, now everybody can share in our once elitist reference

So scrubbing a painted bottom while the boat is afloat is somehow more environmentally friendly than scrubbing it while the tide is out? I don't think you are going to get out the sander and strip the bottom while a boat is careened; maybe on a tide grid (but that's why tide grids are disappearing).

The thread is about doing complete bottom jobs while careened, which tend to require a little more prep work than just simply "scrubbing a painted bottom".
