under the access lid on the left side of v-berth. >>
I have a P19 and reinforced the area between bunks with 20 oz woven roving,
Vinylester resin and another coat of 8 oz woven roving about 2' wide and run
from side to side. I installed a series 27 battery in middle against the
foam. I got paranoid about dropping that big battery and making a hole in
boat...
