Agree. Cleaned my 36 footer's bottom using the orbital sander w vacuum and it is a huge job. I was in between job opportunities so low on cash w a lot of free time so I did the Interprotect barrier coat too. Did the last bits using wet sandpaper and had a hose clamped on a ladder lightly spraying the hull to wash it away. Nice method for me, but EPA doesn't approve. Swore I'd have it soda blasted next time.
Last year I changed my bottom paint from VC-Offshore to Micron 66 and priced sodablasting; $1650. Couldn't justify that, so I wetsanded my hull using a doodle bug and 3M scuff pads and wetsandpaper. Didn't take all the paint off, just scuffed it for a good mechanical bond. Bottom maintenance trick: When I haul the boat, I follow the guy with the pressure washer and doodle bug the whole bottom while it is hanging in the slings. He takes about 20 minutes and I take maybe 40, so the guys go to break or lunch while I finish scrubbing and rinse. All the water and bottom paint falls into their paint containment system and gets filtered, meeting EPA regs. The boat looks ready to launch all winter.

A friend is having his Morris 36 stripped at the yard where my boat sits (in the water). They went through some peel away stuff, then some random orbital (air powered) and then again with some finer sandpaper. It has been a couple of weeks...... Last year they had the soda blasting folks come in and after about four hours, the bottom of a larger boat was as smooth as it came out of the mold. I just don't get it. I'll ask my friend what he was thinking tomorrow at lunch.... After going through that mess and brute labor a few years ago, I would never do it again, no matter how 'easy' the tool is - I just don't want to stoop under a boat holding any tool over my head, taking off toxic crap.

I'd have thought the finish would be much rougher.

Once has to nearly sharpen the blade ever other second. This year I discover using a good tool really matters. Don't use a steel scraper, pay the $23 and get a tungsten carbide scraper. One blade will last a whole side of the boat or more. I was amazed. Here is a link to a scraper I used on a 38LF.

There are many layers on the boat that have accumulated over time. Ordinary manual scrapers take a lot of time and energy, and sharpening. I developed this scraper which will fit in any reciprocating saw and uses a carbide blade. It is a lot easier and quicker and the blades last much longer than regular steel blades. Here?s a video: https://www.youtube.com/watch?v=_2lsNuCrfgk Now, all I have to do is get at it as soon as the rain stops for a few days and the temperature becomes bearable.
