Observe your "typical" fuel consumption
On a typical crossing of the the Straits of Georgia
(West Van to any one of the passes) or on passage
from Gibsons to Madeira
Park my Vetus 3M-10 uses 2 litres per hour on the average, so at 5 knots for a 30NM passage
, which is as much as I usually care to do in one day, I'll use 12L, say 3 gallons.
So for messing about the "Salish Sea", where fuel docks are a dime a dozen, how much capacity do I really need?
An "adequate" tankage for me would be 50L, say 15 gallons. giving me a maximum range of 125 NM. 125 NM is a run from West Van to Seattle
non-stop, or a return trip West Van to Lund non-stop. So how much more do I really need?
A rectangular section tank, 30 x 30 x 55 centimetres will hold 50L if my math serves. That's roughly 1 foot x 1 foot x 1 ft 9 in. Not very big at all!
Small tank, always running on the top half, and keeping the filter fresh seems to do it for me. In a small tank the muck in it gets agitated when pressing up and goes straight to the filter. Filters are cheap
, engines are not,
Small tank, pressing up every day or two, means that fuel doesn't have an opportunity to go "stale" before it gets used.
From your home port to Vancouver/False Creek is a tad under 100 NM. But your engine is prolly a 4108, so you might like to carry twice the fuel I do to obtain about the same range. If you plan to go north, you should add some, of course :-)
