Re: Charging batteries with engine while sailing
tib- most marine engines are OK at normal heel angles of up to about 15 degrees IIRC.
One thing to consider is the fuel pickup location if you are running the engine while sailing, especially if you have two outboard tanks and only one pickup tube. I made the mistake of starting the engine while heeled over to starboard and sucked air out of the port pickup tube because the fuel had drained through the transfer hose to the starboard tank. I have separate pickup tubes and the tanks are not connected now:-))
