[PSUBS-MAILIST] MBT valve

Alec:

The problem with boats left in the water for an extended period is expansion of heated air during the day, than cooling later in th day which contracts the air and the boat to settle deeper in the water. One solution is to add a ball valve to the flood port (inlet) which will prevent the loss of air volume. 

On your boat if I remember right your. M b t's are open at the bottom. Perhaps a fitted plastic plate with a rubber gasket and attached with a bunge cord might help keep water out.
