You must have a crystal ball Dobbs! The next thing after I completed my harbour project was going to ask you about the sailing qualities of Lateen sailing and if it could be reduced to a simple formulea. It seems from my scant reading on the subject that the one advantage they seemed to have over square riggers was the ability to sail closer to the wind. I look forward to your further research and hope that it will provide me with a basis to go on better tan just using the catch all of Sloop cards for movement.
