As others have astutely pointed out above, the economic viability of gas turbines in ordinary sized sailing yachts (10-15 meters) will come only if and when the electric car industry adopts gas turbines as range extenders. The Capstone gas turbines are used as range extenders in buses, not cars, which why MME are trying to sell them for yachts over 35 meters. However, I believe the S/Y Lethantia uses traditional reciprocating diesels for propulsion when motoring and the gas turbine only for hotel
loads. I believe a 30kW Capstone gas turbine would be fine for an electric propulsion sailing yacht in the 15-20 meter range (the electric Lagoon 440
came with a 22kW generator), just expensive to buy.
