About 2400, including finish work. But not including the carbon foils and their molds, which we contracted out.

What RPM’s are you cruising at with those 90’s and those numbers?
if you’d share it would be great to hear how that changes through the range (speed, rpm, nm/g) (I know you said it’s designed for that cruising speed, just curious)
there aren’t too many similar boats to get comps with and as I think about another build I’d love any other anecdotal data!
thx

Wow. Nice looking pictures of the building process, too. Very pretty work.

I know Irens designs have been mentioned here, but I can't remember if "Wilhelmina" has featured. Irens sums up the point of this thread:
“I’m on a personal crusade to help people understand that there doesn’t need to be this huge cultural divide between a sailing boat and a well-designed motorboat,” he says. “I believe a motorboat can give you a real sense of well being in the same way a good sailing boat does.”
To my eye the windscreen aesthetics could be tweaked a little.

It isn't easy to arrange flat glass panels to match a curved profile.I know Irens designs have been mentioned here, but I can't remember if "Wilhelmina" has featured. Irens sums up the point of this thread:

Hmmm, they spent a lot of time on that deck to windshield design. I personally think it might look better with a 3 piece curved glass arrangement. It
It’s cool to see an old school transom hung rudder and stepped deck sheer though!

The transom hung rudder is surprising. 0.4lph at 11kts is impressive. 25hp Beta on a 31' powerboat! Very cool.

I like it. The contrast is very cool, the transom hung rudder unexpected.

The figure I quoted is 0.4 Litres per mile, not per hour. A "94 nautical mile passage [...] at an average speed of 11 knots" is 94 / 11 = 8.54 hours; 37 Litres / 8.54 hours = 4.33 liters per hour.
That's 1.14 gallons (US) per hour or 9.6 NM per gallon.

Rumor has it that the original “sailor’s motorboat” is for sale.
George Griffith’s SARRISA the ULDB designed by Michael Peters.
I will try to get more details.

That looks like the perfect Catalina boat.
Google turned up this article on her: https://www.powerandmotoryacht.com/blogs/still-cruising-after-all-these-years
25kt, 4-5nmpg. Amazing if true.
