As a TDS member I second the understanding and compassionate attitude that will prevail with such a post.
**snicker snicker snicker**
Actually, I think they'll be even more cruel. (hence I think your *snicker*)
Prob still not as interesting as some of the posters on Usenet
REC.SCUBA though. (they always have such creative responses there...

)
By the way, roughly 150 years ago I picked up spare change cleaning hulls in the Elizabeth River in VA, until I got a superinfection from the crap in the water, I will not clean my own hull now, I pull the boat out of the water...
Ouch! That had to hurt!
Catfish. First off, welcome to the board. I hope you have a great time here. None of us, me included, meant to get off on the wrong fin (foot) here.
With that, I'd offer a different approach to making some extra funds cleaning boats. Check to see if the marina near you has a floatin dry dock. I know of one or two near me that have them. They are large docks (20' by 30' for example) that have a ballast floatation system on it. You set up the "stands" on the dock to match the hull you want, "sink" the dock (fill its tanks with water) drive the boat on, and slowly pump the tanks out which "floats" the dock again.
Boaters can rent this dock by the day or week at one of our marinas to do work on their boat. You then see them doing several tasks such as bottom cleaning, painting, installing thru-hull fittings, etc.
You could still make extra funds cleaning the hulls, but safely and above the waterline. In fact, it'll be easier with the use of a gas powered pressure washer. But as one poster said, be carefull of hull damage. Blisters are the most common hull/fiberglass paint problem. Considering a new Sea Ray 50 footer runs abot $600k or more, I'd hate to have to pay for his new bottom job.
Other marinas, especially those with dry storage, can quickly pull a boat of up to 40 feet and set is on stands/blocks with the standard yard forklift. This is a great above water way to clean a hull.
Other yards typically have a "sling lift" or what's called a "travel lift". These typically cost more as they aren't used 100 times a day like the dry storage lifts are.
Having it out of the water also allows the boat owner or tech to "inspect" the hull for any other damage (blisters, electrolysis damage, checking the zincs, prop "tuning", etc).
This is also the perfect opportunity to check the gear-oil in the lower unit (foot), etc.
Hope that all helps. I'm sure there is some money to be made in it (out of water hull cleaning) if you get everything set up.
Hope that's all helpfull to you.
