I bought on of these for 2 of my Grandson. One has already forced his Mother to filled the tub so he could try it out. It would appear that it was big hit. Not sure where he got the wind to sail it though.. I am looking forward to sailboat races here at the Marina I live in.. I am considering buying one for myself so I can join in the fun.. It also may be a useful tool in teaching the basic of sailing to two of my Grandson. Who have been bugging me to sailing aboard my 41 Foot Morgan!
