The more you think about this vehicle the crazier the concept becomes.
For me a small boat is fun and relaxing but the bigger can be stressful as you eventually end up in a situation where you have to worry about crashing. The little ones, like the sunfish in my pic, bounce off docks generally. The common little flat bottom boats are a blast in how you can pull up the centerboard and the rudder can be lifted and can sail right up the beach. Capsizing is no big deal with the little as well and can easily be righted again.That was an interesting video, thanks for posting.
I just got a small sailboat late last summer. I'm still learning the ropes (or lines if you will) but so far it's been a blast. My youngest and I are itching to get it on the water but I need to finish residing my house first. We're looking forward to getting proficient enough to do some island camping with it.
