Rake of the mast

[Captphil2412382]

I have been working on adding mast support (in addition to the compression post). Now that I am finished with this, I want to tune the rigging. I understand that the mast should be slightly aft of vertical
The boat is a 1975 27 ft.

Mast Rake

Phil I would start out with the mast straight up and down, then take it out for a sail. If the boat doesn't feel right such as a lee helm try raking the mast beck a little at a time until you get the feel you like. Ray T

Mast rake

The rough number for mast rake on most production cruising boats is 1 to 2 percent of mast height. The Hunter 27 came with various mast sizes, a standard rig and tall rig. Standard mast height is 33' 1" and tall rig 36' 3"

If you have the shorter mast and use an average of 1 1/2% the rake should be set at 6". For the taller rig the rake would set at 6 1/2".

Also a factor would be the average wind conditions in your sailing area. Higher wind areas, like San Fransisco Bay, might require slightly less rake, say 1%, whereas lighter wind areas might use 2%.

After dialing in the rake and pre-tuning your rig you should take the boat for a test sail. Note that a test sail means beating with correct sail trim on both tacks.

Thanks for the tips.

Just what I needed. A good starting point.
