Combined engine/gen for hi-spec sailboat
With increasing quantities of electrical equipment aboard arealtively small boat, larger amounts of power is needed to propel the boat and to provide the necessary electrical supply.
So, instead having a single engine and a separate add-on generator, the two engines are supplied and fitted right from the start, and balanced to ensure lateral stability. This means that both should be the same size, and of course this handily means a lot more manoauvrability in port with TWO engines available rather than just one.
These days a similar sized lump that once gave only 50 hp can now provide 200 or more, so it's an ideal opportunity to spec these, with which the boat will actually be able to approach and even exceed max displacement speed. For economy, you may also want a backup generator rather than running the main engines, and the performance with engines on may mean that you can actually save money on the initial purchase by not speccing the mast or sails. Good eh!
