I was wondering, in order to avoid another hole under the waterline, how to convert a ordinary freshwatercooled via heat exchanger
to keel cooling
I mean in a used boat
with fiberglass hull
I thought about cut a square between the ribs of the hull
, replace it with a sheet of aluminium, that goes bigger then the hole, laminate it with fiberglass
for a pair of inch on all the 4 side, both exterior at the hull, both interior
, and on that aluminium sheet add the aluminium box (smaller, to let alluminium dissipate heat and do not overheat the fiberglass around )
Any idea also how to delete all the holes under the waterline?
I thought toilet all to a black water
tank with macerating pump and reversed U at the stern so no bad small, bilge pump
is ok; for raw water
sink and watermaker
a small pump that can lift water
, placed at stern with the same reverse U shaped plastic pipe with a small "buffer" tank.
Both the pipe at stern laminated to the hull for estetic reason
