Subject: Mizzen Chainplate Position
In reply to: Paul M31 #106 NJ 's message, "Mizzen uppers/lowers" on - Tuesday - 03/22/11 - 8:10pm

Paul,
I've been meaning to ask you about the mizzen mast position and where to attach the shrouds. When you had your mast positioned with the uppers attached to the middle chainplate did you check to see how much rake the mast had? I read an article by Brian Toss that talked about putting enough rake in the mizzen mast. When Shadows mizzen was up I measured about 9" rake with a plumb bob. That was with the mizzen upper attached to the forward chainplate. Shadow seemed to balance well. How did your Mariner balance with the upper shrould on the middle chainplate?
The pictures are nice.
Kathy

As you can see in the picture, the rake of both the Main and the Mizzen is minimal... I would say perhaps 3 inches on the boom using a plumb bob - I also don't think moving the stays to their proper position will change the rake by much.

When I step the masts this year, I will see if I can induce a bit more rake - I like it to be arounf 6-7 inch on the main and around 5 or so on mizzen - too much and I am afraid to produce too much weatherhelm.

Last year the balance of the boat was minimal wetaherhelm - I'd like to see a tad more for safety.
