A pure electric boat is still pretty tough to operate in the real world.
For now a hybrid seems like the best choice.
I met my 48′ daycharter customer at IBEX where he showed me his add-on electric motor.

Looks pretty cool.
The top one is an add-on with an existing engine. The lower one is for a new installation.
Andre Cocquyt is now blasting around in his 34′ KHSD power trimaran.
This is a new 44’ powercat design by Kurt. It is simple, elegant, and perhaps the most bang-for-the-buck design I’ve seen. Kurt estimates displacement at 2550 kg/5600 lbs, which i suppose indicates the boat dry would be 4000 lbs and change. This would be a very easily driven hull. 2x 50-60hp outboards should be sufficient to go fast, and the mpg is going to be spectacular. Twin 40 gal tanks should give a range of 400-1000+ miles depending on conditions and how fast you want to go. Beam as designed is about 18’/5.5m, but could be easily increased for more deck area.
I am a professional boat builder and this is a boat I would love to build. A client of mine has commissioned these plans from Kurt and a detailed construction spreadsheet from me. At the moment they are unsure whether they wish to proceed with this design. Plans might be available at a discounted price. If you are interested, we are available to build this boat during the coming winter in Sarasota, Florida. If you are in Asia we can arrange to build this in the Philippines.

My 65′ power daycharter catamaran was recently photographed. They do amazing tours. You can snorkel among the fish and turtles.
My 35′ power trimaran, built by legendary boat builder Andre Cocquyt. Foam/glass. Andre notes:
our trials got cut short due to hurricane Lee, the marina evacuated and it’s too late to put back in before the season ends per Oct. 1st. I saw 23.4 mph on the second test run. she likes to cruise happily and quietly around 3,400 rpm doing 14 mph. With engines in idle fwd, she does 6.5 mph. It will be interesting to see how she does next year with the trim mods and the swim platform.
My friend, brilliant designer and builder, built one of my power trimarans.
It looks wonderful. Especially when I stand back and look at it.
A pair of 50 HP, 4 cycle outboards pushes it at 24 knots. Sea trials were cancelled due to hurricane.

This foam/glass power cat is being designed for a customer in Crete. 22′ and 10 passengers.
My 32′ power cat was originally designed for a Hawaiian customer to be able to travel between islands with a place to stay.
It looks pretty good to me.
I just got this picture of my 34′ daycharter catamaran operating on the north shore of Kauai. beautiful.
Bob sails his 34′ KHSD powercat on the north shore of Kauai, which the USCG considers the most extreme weather in the US. He does the Napali coast tours. He has to take the boat out of the water at the end of every tour as there is no safe moorage.
34′ x 12′. He has to come out on a narrow ramp. Foam/glass.
