On the answer to, "What is the difference between a screacher and a Code 0" The screacher is designed to trim inside the shrouds and be used with a sheeting angle narrow enough for light air upwind sailing. The halyard
should be a 2 to 1 and not far above the hounds fitting. The loads on the screachers are quite high so, strong, low stretch material should be used for the sail and the halyard
made of a good low stretch fiber to minimize stretch.These sails
do work well reaching but, will not be best for very low reaches and downwind. The Code 0s can use the spinnaker
points of attachment on the pole, halyard, and sheet blocks aft, as these sails
should be sheeted out side the shrouds and designed to offer the maximum sail area, for the triangular profile.
If there is an asymmetrical spinnaker
on the boat, a screacher may be a good choice. For the one sail to do all, the Code 0 is what we usually recommend.
Make sure it has a large enough anti twist luff rope
and a durable material heavy enough for a light weight Dacron U V strip to be included.
