But we are talking about an aluminum boat. Aluminum doesn't blister,
eh? I guess the algae concern might vary with the lake. Lake
Vermilion boats sit for months without significant algae growth. The
rocks don't get much either.
LOL, I didn't notice it was aluminum.
NEVERMIND.
As far as the algea or lack there of at Lake Vermillion, I wonder why
the water does not grow algea? We need to find out what it is and
bottle it, and make a million. 
water that isn't very warm and has relatively low levels of nutrients
doesn't seem to grow much algae. Just reporting observations.
