Re: fuel usage
I recently completed 10 hours cruising in my Bristol 31.1, with the Universal 5424 (pretty much the same engine as the M30)
I ran at 2000 rpm, at about 2/3 throttle, which gives about 6 kts.
Fuel consumption was 0.8 gals/hr, and this equates to about 7.5 nautical mpg. I think I would plan for 1 gal/hr to be on the safe side.
5 gal containers are inexpensive and you could easily carry 2 or 4 of them.
If you have a 20 gal tank, keep a 1/3 reserve, plan on 1 gal/hr, and motor at 6 kts, your range is about 84 miles.
