Started our second year living about Red Ranger by hauling her out of Jackson Creek.

And washing her for the first time in—at least—two years, maybe closer to 30 months.

Of course, we had barnacles everywhere. And "soft growth" (algae) that was right thick.
So far, we haven't found any blisters in the hull.
There are numerous chips where the paint hasn't bonded perfectly well to the hull. That requires a little sanding and prep work.
Otherwise, we have three huge jobs (40' long, 6' under water, 4' above water, 2 sides: 800 sq. ft.)
-
Wash the topsides. This is brutal work because of the ICW mustache. It's a brown stain from the waters of the ICW. This requires scaffolding. Unless you've got a mile of planks, one person washes while the other person does nothing until it's time to move the scaffold.
-
Sand the bottom. This is brutal work because the bottom is covered with poisonous paint. Sanding raises a dust that's hazardous, and requires breathing apparatus. Plus the sander must be connected to the shopvac to keep the dust from blowing all over hell and breakfast. Unless you have two shopvacs, this is a one-person job.

Paint the bottom. This isn't so bad. Yes, you're dealing with expensive ($100/gallon) paint that's lethally poisonous. But. You don't have to be very neat. Just glop it on.
