storm sail shape

taking 80% of the ORC formula i've come up with sail sizes of 135sq ft (12.46 sq m) for the storm jib and 110 sq ft (10.36 sq m) for the storm trysail for my nauticat 42

question now is: are there any guidelines for the shape/geometry of the storm trysail and storm jib?

thanks

Flat and high cut for the jib. Heavy fabric triple stitched.

I don't think anyone would "normally" paint a sail.

Either
(a) Get it made out of a high visibility colour (flouro pink is good), or
(b) Get it made out of standard dacron, and have your sailmaker stick a large high vis patch on both sides.

Incidentally, dacron is generally the way to go. Kevlar / carbon are not recommended for storm sails.

I agree with the previous poster who said that high cut is the way to go.

Some storm sails have a full-hoist bolt rope, even though the head of the sail is only 1/2 to 2/3 hoist (maybe to stop the halyard slapping on the forestay?) If you do have a bolt rope and foil feeder system, you should have eyelets fitted into the luff so that the sail can be shackled onto the forestay if necessary (extreme winds tend to pull sails out of feeders). It is also a good idea to have sheets permanently fitted to the clew for ease of hoisting.
