Unless you get rid of the system completely the size has little affect...Except when it comes to the Hull
All engines need fluids checked. All boats are sensitive to trim..maybe not fuel
but on a 67 footer i bet you care less where the can goods are stored..
..All boats need seeps fixed or else!..
I could go on and on.
I see the shear size of the hull
as being the maintenance
hogs not the other stuff....shoot I bet you can walk in your engine
room to check fluids , change oil
or put a can of beans on the engine
to warm up...try getting access to change both V belts on mine...and the sea strainer's?...well that's just another...
