Load Difference
I bought a radial head spinnaker - called a Flasher from UK Sails off the Hunter Owners store website in 1999.The UK info sheet from the company's website said that radial head sails were typically used on boats which are 27' or less. The tri-radial version is designed for loads created by bigger boats, but normally not sold for smaller boats. Suggest you contact the Hunter Owners website and ask who makes the ones they now sell - I think it may be Doyle - and check out their website for more info. My radial has been fine, but is used only in light winds.
