sander and the job was complete to come back with new barrier coat then Micron77.
Our boat is a 16m (53') ketch
with a mod wing keel
and skegged rudder
. This should help you in determining how long it will take. Be sure that who ever does this work wear protective clothing
and a good respirator.
If you have any blistering in the gel coat, this process will make the blisters
obvious. Be sure to repair the blistering and also be sure to buy a good barrier coat...really stupid to pinch a penny on barrier coat, but I know some who have done this...freakiing nuts!
You will get lots of opinions on brands and types of antifouling. You generally will get what you pay for, and I have found most complaints about antifouling come from people who take shortcuts in preparation, etc.
I had the same experience. I scraped my whole bottom in two days, no tenting needed, just lay down a tarp. This is absolutely the cheapest and easiest way to do this job as long as there is hard, dry paint
on the bottom. Most of it will come right off perfectly to the gel coat. I only had difficulty with the 6 inches or so above the water
If there are years of soft paint build up, you will have to sand, but my thoughts there are, why not just do nothing, and the paint will remove itself over time while the boat is in the water?? That is the point of soft paint.
