The weight and size of a diesel genset are other considerations. While diesel fuel may be less volatile, if the diesel alternative is too large, heavy and expensive, then taking the extra precautions for using gasoline may be justified.
Along those lines, a diesel engine may not be that much safer than a gasoline engine anyway. Here's a link to an opposing perspective:
http://yachtsurvey.com/GasDiesel.htmI personally know of hundreds of boaters that have operated their gasoline powered vessels for many thousands hours collectively and none of them have had an explosion or fire onboard. I think that the dangers of using gasoline in boats (and cars) can be overstated and other commonly accepted aspects of our transportation should be a greater concern than the choice of fuels.
Kind of ironic to have this debate on an electric boat forum...
Fair winds,
Eric
