A quick peak at the 2015 QU4D sails on windy, but pretty flat Maui. The new QU4Ds have the same outline with a slightly modified luff curve to place the draft a little more forward. The sail is definitely stronger built with the same fabric layout as the KS3. Color shown is C1. Sizes sailing 4.7m and 5.0 in too much wind gusting to 35mph.
Pushing the sailors and the Phantom to their limits.
