Here is the prop. Weight to Sail Area rule scale applied to the various designs listed .-Keep in mind that mainsail area from max may be transfered to the jib area maintaining the total equally to allow design variation, and that a spin area increase { 2 to 6 % }will be added to heavier masted existing designs.
<br>-Note : max spin area may not always prove fastest , we may find a certain aspect ratio spin performs best through a range of conditions given the same hoist height on the mast and spin pole length.
<br>
<br>-note; varied Weight slightly for example purposes ,-as we know mfg. advertised W will vary , each will be weighed.
<br>
<br>--N-6/0 --W=420 - - M-Sail 220 - - Jib 60 -- - Spin max=330 + % factor of mast -applied based on mast weight,all designs

<br>-plus % for heavier mast if used
