I tried this out at a gym in Wandsworth, London a few weeks ago, and thought it would be perfect on the yacht (63ft).
I can't explain how solid the work out is but I would suggest you to try it. I will have the system up in Italy, Croatia, France, Spain, Canary's and in Antigua later this year. Feel free to pop over and try it out.
There are plenty of videos on you tube and on there website.
