Cary,

Here's a link to the Taipan 4.9 manufacture's website. If you choose "Owners Manual" from the left menu, it will take you to a list of articles. Two will be of interest....one on Wingmast Aerodynamics and one re: Sailing with a Wingmast.

PS...sorry about not just providing direct links, but the site doesn't print individual URLs as you navigate.
