Just got the first test production run of the New Maui Ultra Fins Delta XT. Looks interesting and I can't wait to get it on the water to see how it goes. The surface area of the New Delta XT is about the same as the Original MUF Delta but they have move it from the front to the back. The Delta XT has less rake than the MUF Delta. The Delta XT has been designed to have more grip and get up and go than a MUF Delta and fingers crossed it will be lighting fast. Unfortunately the first test production run was only power box but that's good for me with my Twin Fin power box boards. Also only in sizes 18,20 and 22 the next production run should include 16, 24 and 26
