Radio-controlled sailing model | Stability (i.e.not tipping over)

Stability - the ability of the model not to tip over - is a function of hull design, and most models have ballast keels. Unlike many full-sized racing boats, centerboards are seldom found on racing models. Like full-size keel-boats, model yachts will sink if they fill with water. For this reason a fiberglass hull is a top choice for the beginner unless he has the skill to plank up a watertight hull. To insure that the hull stays dry inside so the model won't sink and, equally important, to keep the radio receiver and equipment dry, the hatch should be designed for easy removal and yet be sealed tight for sailing.
