[Public-List] stern squat

[Glennb]

Hey David,

I looked into my tank today, estimating how to rejuvenate it for potable water.  The interior appears to be glossy finished gel coat but with decades of black staining from algae and chemicals/salts etc in the water.  Also the last gallon area in the bottom of the tank is blackish- green from gunge.  The top and edge surfaces are hard to impossible to reach.

How much surface prep did you do to your tank prior to coating with epoxy?  Iam thinking a good sanding is in order, which will entail cutting a largish access hatch in the top and glassing it back in afterwards... How muchof this work is necessary before coating with epoxy?  Also how many coats of epoxy did you use?

Thanks
Glenn B

I have thought that the weight of the of the A 4 and the gas tank just about balanced the weight of the water tank and the full holding tank. Was this Carl's genius at work or was it just luck? I would like to think Carl knew what he was doing, but am more than ready to be corrected by those who know more than I do.

I installed a couple of small eyes with light line woven through to tie the BBQ tight against the bulkhead so it  doesnt flail around and hurt my selfsteering and other stuff.  Works great.

I Adopted the old fashioned method of installing eye bolts through the deck on all four sides of the front and rear hatch, and on the sides of the cockpit walls. Then tie the hatches down with line woven from the eyes  across the hatch, or in the case of the cockpit lockers through for and aft holes in the locker seats down to the eye bolt. works great!  Doesnt cost much.
