Fractionally rigged boats
I am not sure that one can give you a complete list as fractional rigged boats are pretty common in this size range. Several fractional rigged designs or companies that made frac''s in that range that come to mind would include the Tripp 26, Laser 28, Albin, Seasprite, Tartan, Santana, Ericson, and Kirby 30. There must be literally 50 to a 100 fractionally rigged models in that size range.
Can I ask why you are looking for a ''complete list''?
