The 2m catamaran is a boat being designed over the 2013-2014 school year. It will be a racing swing rig catamaran modelled on other rc sailboats. As it is currently under development, there are a number of details that must still be determined.
Overall Dimensions[]
Currently it is designed being 1.80m in length, 83cm from center of hull to hull,
Hulls[]
The hulls have been modelled using SolidWorks. The cross section of the boat was designed using a NACA 0030 foil and then scaled up to a size that fits the 1.8m length of the boat. A few cross sections of different sizes were used to have a tapering design. The hulls also have a low point in the middle and loft upwards to the front and stern of the hull. Up to now a daggerboard trunk, bulkheads and sleeves for the 2" cross beams have also been modelled in.

Sails[]
The main sail will have an area of 1.07m^2, and will be 0.41m^2 for a total area of 1.48m^2. The estimated wind load at 35 kts is 38.15 kg, based on the "Sail Wind Load Calculator". The main will have a height of ?
Swing Rig[]
Keels[]
Rudders[]
Beams[]
The beams will be aluminum, and have a rectangular cross section. The plan is for them to be welded at the McLaughlin Machine shop and heat treated our selves in Nicol Hall.
Currently looking at 2" square tubing.
