The Hobie MONOCAT 12 is a 3.6-meter catamaran dinghy designed by Hobie Alter and built by Hobie Cat from 1973 to 1978. It features a Marconi cat rig, a single daggerboard, and displaces 68 kg. The MONOCAT 12 has a 1.2-meter beam and a 0.2-meter draft. The Lady K Sailing channel emphasizes that learning to sail on a dinghy, such as the MONOCAT 12, provides fundamental experience in wind dynamics, hull hydrodynamics, and sail aerodynamics.1:41 The channel notes that fiberglass dinghies are durable and easy to transport.
