Securing holding tank

[wchevron]

i'm installing a new holding tank in the v-berth. (no previous holding tank) the backside will be against the bulkhead and the two sides are wedged against the hull and a bumpout in the v-berth. i was thinking wrapping the tank with plastic then pouring expandable foam underneath it to keep it in place. then on the accessible side glassing in some plywood to keep it from moving. my thinking with the plastic over the tank is if i ever have to remove it, the foam won't be bonded to the tank. any thougthts?

Sounds like a good plan wc. One thing I would add though, is to also fasten the tank securely to some structure, perhaps by using welded tabs if a stainless tank, or banding the topside with strapping if a plastic tank.

Perhaps the form-fitting installation at it's sides and bottom is sufficient, but think what may happen to an unsecured holding tank during heavy seas, or a knockdown.

To hold my 35 gallon tank down we use stainless ratching tie downs. It will be able to be removed if needed.

I would consider some thru-bolted pad eyes attached to some straps.
