Remote Control Boats - Styles of Hulls

The next considerable determination is which kind of radio controlled boat hull to select. If your are setting up a scale project, your preference will clearly be determined by the full-size vessel you desire to model. But sport, racing and sailing craft hull types present very different characteristics. In general, there are two hull classifications: monoplane and hydroplane.

MONOPLANES
Monoplane hulls contain one continuous surface in contact with the water. Monoplane hulls can be separated into 2 subcategories: deep-V's and shallow-V's.

Deep-V's. A large amount monoplane hulls are deep-V's. This typical design brings the keel to a sharp point well beneath the surface of the water. The underside of the boat is sloping upward steeply toward the hull's sides, resulting in a radio controlled boat that knifes through the water with a comparatively large wetted surface area. This style of hull is stable at every speeds and provides sharper steering response. The downside is that the added hull surface that contacts the water causes drag that restricts top speed. Still, as well as the right power system and proper tweaking, these radio controlled boats are plenty fast—especially for the beginner.

Shallow-V's are the faster of the two monoplane types since they operate with a lesser amount of surface area in contact with the water. The shallower keel v's-angle produces a flatter bottom that causes less friction. The downside is that a reduced amount of contact with the water means less stability, so they are more difficult to control and demand more accurate trimming. Shallow-v's are very widespread for entry-level racing, the so-called Crackerboxes being the most common.

HYDROPLANES
Hydroplanes have more than one surface in contact with the water. They consist of tunnel hulls, catamarans, outriggers and stepped hydros.

Tunnelhulls are most often connected with full-size racing boats. They get their name from the raised center portion of the hull. 2 outer sections (sponsons) sit in the water with a “tunnel” between them. As the boat gains velocity, air builds up in this tunnel and raises the boat higher out of the water; this reduces the surface area that contacts the water. This means less drag and higher speeds, while the relatively wide spacing of the sponsons maintains stability. This design provides a good balance of speed and handling for beginners.

Catamarans (cats) operate on the identical principle as tunnelhulls and differ only in profile . They have more steeply angled sponsons—much like deep-v's monos with a tunnel along the center. A cat's tunnel tends to be taller and narrower than a tunnelhull's, so it takes longer to preserve stability. These also, are a good beginner model.

Outriggers are at the apex of the performance ladder; their sponsons and main hull are separate pieces. This improves the airflow at high speeds, so outriggers are the fastest radio controlled boats; a number of even run at more than 90 mph! The hitch is that they're intended to work best at full throttle. At slow speeds, they sit too low in the water and don't handle well. Also, they are the least forgiving when it comes to setting the trim.

Stepped hydroplane hulls have notches perpendicular to the centerline that divide the wetted surface into 2 or more sections. These notches pick up the radio controlled boat up on step faster, and that improves performance. At speed, these notches lessen the wetted area, reducing drag. This hull type includes a diverse group, from straightforward deep-vees with little steps in the hull, to 3-point hydro racers such as the full-size Miss Budweiser turbine-powered, unlimited hydroplane. At full speed, three-point hydros travel on 2 small areas of the forward sponsons and the centrally located propeller at the rear.

Any way you look at it radio controlled boats are a great way to spend a sunny afternoon. Take the time to enjoy the hobby and spend time with your family and friends.
