Somehow, I just don't get it. 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 know sucking in the dust from scraping the bottom is not good - but in the
past I've used a random orbital sander with a fairly rough grit paper (and a
mask)
Seems to go pretty quickly, or at least it did on my little 24'
Are scrapers preferred? I'd have thought the finish would be much rougher.

Hi,
Scraping off bottom paint is a pain with a cheap steel scraper. 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. Bahco 665 Carbide Edged
Heavy-Duty Paint Scraper

I got adventurous this year and decided to remove as much of the existing
bottom paint as possible. 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.
