Did you know that there is a model yacht, which with equal success can do and experienced athletes, and beginners? This sailing catamaran belonging to the class DH. The model is simple, adaptable, and to build it without the use of scarce materials. High seaworthiness and good speed catamaran gives the hull type hulls “sharpies”. You can get them in several ways — with the use of plywood sheathing and a set of longitudinal and transverse elements, with a slinky frame paper and cloth, or — most simple — Villenoy of fiberglass on the disc. Get acquainted with the first two.
Each of the housings has a length of 1000 mm, and for frames from cook pine slats of the longitudinal framing for the entire length of the body: four section 5X10 mm and eight cross-section of 5X5 mm. the Outline frames (1 through 9) carefully transfer the drawing to the plywood thickness of 2.5 mm and cut out parts with a jigsaw. The slot under the elements of the longitudinal set is best to mark in the finished frames. Knife-like aft edge of the hull (the outline shown on the drawing) — 5 mm plywood, a fore end — of the same material.
Before keying grooves in the frames under the rails of the longitudinal framing is necessary to decide what will be covered the case. If paper, then the outline of the frames should understate 1 mm below the transverse “ribs” on the skin did not increase the hydrodynamic resistance of hulls.
