No need to bark.
Well, they did turn cruising into a career for themselves by making
money from it.
Make
money and get well known is what I personally understand is what many would consider a career.
Nothing wrong with that. Good for them that they are successful in doing this.
While I am personally not a big fan of using fossile fuel, I accept that for some its an option and choice.
I will not go so far and condemn that.
For some people a sailboat gets hard to handle in a safe manner when they want to continue cruising in an advanced age. Powerboating can be an option for some.
The Dashews did that and tried to minimize the negative effects by designing power boats which are very
seaworthy and much more fuel efficient than most others.
I'd think there are many many many big scale pollution creators around who have not given that as much consideration as the Dashews do.
