Mizzen Loads on Yawl

[Brion Toss]

Hello,
Have you looked at the section on mizzens in the "Apprentice"? It covers the cans of variables that you are opening. I like getting rid of springstays (not triatics; those are for square-riggers, steamships, and schooners)when possible, but not when the sum of the new vectors makes things worse. As for the optimal angle, an inch per foot gives you less than 5 degrees. Better to have between 5 and 7. The more you get, the less compression and the less tension needed to keep the stick forward. The limiting factor will likely be the main boom.
Fair leads,
Brion Toss
