The ” Malco” 11 foot SUP was designed by Malcolm Schweizer. It has a little concave in the nose and a slight “V” in the tail. Plus the rib design lets you build the rails two different ways (built up solid rails or wood strip hollow rails).
The Orca was designed for stand up paddling which requires maximum flotation and stability. It’s at home on a lake or in the surf. It has a flat bottom and enough rocker that it is at home paddling into a wave,
The “9ft. 6in. Stu’s Sup” is a short surf SUP that was designed for people that want a shorter, more agile SUP. The Stu is meant to be an open drops and hard turns like a surfboard but give the wide stability of an SUP.
