Decide on a sail maker sail.

If I choose a couple of standard (common dinghies) sails. Can the sail maker
(dealer) tell
1. how large mast bending it's designed for (his standard CAD pattern for
that dinghy)?


for a dingy you usually suspend a 50 lb weight from the middle of he luff
position on the mast and measure the deflection for the sail maker. if you
use a mast off a one-design boat (eg a Proctor mast off a Wayfarer) the
sail maker probably has a pattern to go with the mast but it will be the
sail area used on the one-design boat.

2. if it's a weak or strong wind sail?


you can discuss the weight of sail cloth used.


3. Is it usually possible to choose the sails reef technique and /or
fastening method?

4. Can a tube GRP mast match an aluminum one in matter of stiffness? ...or
will it get way to big radius to match?
