Hello Group,

has anyone out there converted an old lifeboat into something like a
'Canal Boat'? I am working with a 26 foot aluminium hull. Presently
building a cabin to make it so i can spend some time on the boat, with
berths and cooking facilities etc. I have an older 18 horse Yanmar
diesel to install. I understand that I will need some ballast to keep
the boat from bobbing like a cork. Question: what kind of ballast?
Cement? and how much? Thanks in advance! Ingmar

What you realy must consider, is the hull ability to stop rolling.
As if you place all ballast ,so it kind of keep rolling from one side to
another like a pendul in a clock, -------- no great idea most often caused
by all the ballast placed at the bottom in the middle of the boat.
Best way to avoid this, is to divide the ballast in 3 ; one third at the low
bottom, and each orher third as near the waterline and as far "out" , each
side of the hull.
The reullt is, that the parts of the ballast at the waterline will move
up-down and not make the hull swing from side to side whenever rolled.
P.C.

With boats like that, you must emagine how
