Some basic questions were asked on my forum about the design of amas. There are so many permutation of ama length, crossbeam width, ama volume with performance ranging from very poor to very good. But what are some of the basic criteria?
In general I don’t like most sailing books and most sailing lessons. I think that a learner doesn’t need to learn many new words. Also because they don’t explain the correct principles in the beginning their explanations become really complicated. If you understand how to use a sail to get power – when it is at maximum power and when it isn’t it all becomes very logical.
