Very interesting and also eccentric in many ways. Some even look like extended tug boats along the waterline. Not my taste but heck, ... I can appreciate the eccentricity and exceptional difference. I guess it is great fun for those involved ... now, will I cross the ocean with one? Yes, the day I have a death wish haha.
Would I enjoy the space and apparent large cosiness inside? Yes, if I looked forward to the fun, didn't want the adventure of the ocean, and had the camaraderie of my fellow (likeminded) sailors! Damn, I am tempted to go and interview them and see what it's all about. I'm not tempted to live that life though.
HORSES FOR COURSES. Have fun there, fellow sailors!
