This question goes to a technical hull design attribute called Prismatic Coefficient. PC describes relationship of cross sectional area at midship to overall length. A low PC means the hull has relatively low displacement in the ends compared to midship - my canoe sterned Willard 36 for example. A high PC would carry load carrying ability to the ends and favor higher speeds of 1.5 S/L or more a broad transom Tiara comes to mind. A racing sailboat is designed with a higher PC because it will be operated at a higher S/L speed as it has the crew and motivation to do so. A cruising sailboat will be designed with a lower PC because it will be rarely operated at much over 1.0 S/L.
Annual pleasure power boating fuel "efficiency" [i.e. per day cost] ... in so far as $$$’s and "sense"
2, 3 and sometimes 4 nautical miles per gallon are the fuel use figures often mentioned. $3 per gallon is the average cost I use here for calculation.
Soooo - - > Regarding the generally accepted average of 200 hours engine-running time per year on a consumer’s pleasure boat ... let's do some base calculations - - - - >
A. nmpg | B. hrs. of travel | C. speed traveled | D. distance traveled | E. gallons used | F. cost per gallon | G. annual cost | H. cost per mile | H. cost per day – levelized throughout the year.
2 nmpg | 200 hrs. of travel | @ 8 knots = 1,600 nm distance = 800 gallons used x $3 per gal = $2,400 annual = $1.30 per mile = $6.58 per day of the year
3 nmpg | 200 hrs. of travel | @ 8 knots = 1,600 nm distance = 533 gallons used x $3 per gal = $1,599 annual = $1.00 per mile = $4.38 per day of the year.
4 nmpg | 200 hrs. of travel | @ 8 knots = 1,600 nm distance = 400 gallons used x $3 per gal = $1,200 annual = $0.75 per mile = $3.29 per day of the year.
Therefore - - > In general… we may either own a boat that only costs $0.75 per mile [avg $3.29 for fuel per every day of life] – or – own a boat that costs $1.30 per mile [avg $6.58 for fuel every day of life].
One way or the other – if a person can’t afford from $3.29 to $6.58 per day to fuel their pleasure power boat – then – they should probably not purchase nor try to even begin owning a boat.
However – if you can afford that fuel cost - - >>> THEN GO FOR IT!!!
Happy Boat-Fueling Daze! - Art
Of course!
However, in the context of "pleasure boating" many million participants: You [and many others too] are anomaly for extensive hours run-time per year. A very happy for you [at least I believe from reading your posts that you are happy] boat using anomaly.
And... where are you purchasing fuel... $5 per gal? That could be and fuel costs may in general be considerably higher than the $3 price I based my calcs off of. So... the per day outcomes I listed simply need an approximate 60% upward adjustment. Even so, and although boat costs always should be paid attention to, boating is still a pretty affordable "big-time" passtime for many people.
Regarding you needing a fuel economy hull/engine, due to 600 to 1000 hrs. annual run-time. I understand and fully agree!
You missed the tense (past tense) of my $5 per gallon comment. That was more than 10 years ago under the previous administration. It had a chilling aspect on the recovery.
This is what I paid last month as I don't live on the West Coast.

You're pretty tricky!
IMO:"has been" could be used as current or "past tense". "had been" can not be current... only past tense.
ONLY $1.47 a gallon - OMG!!! It's almost like they are paying you to cruise!
