A friend bought either that or a very similar product about 5-6 years ago. We all took turns with it for a couple of weeks, on and off, and then it disappeared and he went back to having a diver clean the hull
IF you don't get much growth, and IF your hull
shape is fairly shallow and easy to access, it might be good for you. Trying to get all the way under a typical keel boat
, or rub down the keel
itself, just doesn't happen.
