It is not likely you have heard of the sailing motor vessel, the Freewinds. See the virtual tour.

It is not a well-known fact, and being the people that they are, they don't crow about it -- but the people on this ship have done a number of a heroic things, as well as being very contributory to the their ports of call.
Providing entertainment, a venue, goodwill and even helping to educate local children on life at sea.

I am including some different things to look at here, giving you the specifics on their activities.

To me, these people warrant deep respect, in that they are helping others on a constant selfless basis.
