Rhosyn mor has all bladder tanks
for potable water
, they work fine. Our fill is the standard in deck
one, there would be no reason why one could not fill them from inside, people do it all the time with hard tanks
.As long as they are vented, there is no difference. Be sure to cushion them well to protect them from chafe, and have them tied in place so that they can expand and yet not move. We have two tanks on board, both plastimo
, the bigger of the two is 15 years old and in perfect shape, the other is new.
Another suggestion, if I may, is to have a bladder tank in yer dinghy
, when you need to refill the mother ship ( say in harbour when you cant use the watermaker) take the dink over to the dock
, fill the bladder, and then with a small 12V pump , fill the big tanks ( works with fuel
as well tho not in the same tank
) when yer done roll the bladder up.
