Pretty Cool! Awesome sail color.
Where you able to test the boat's speed without it for comparison?
Adding another sail to our arsenal could be beneficial.
I wasn't able to compare for heading to weather; but I did test it off the wind (prior to the video of the sail itself). Without the sail and using jib, I was not able to make any way against the 1 kt current...basically, I was stuck in one spot barely making way toward my goal. After hoisting the windseeker and fixing some rigging issues (like I said, some things didn't work perfectly
) the boat was able to make way against the current and had a respectable SOA given only 4-5 kt breeze. Toward the end of the sail (after the video) the current went slack and even helped push us toward the marina (I counted on that in case "(censored)" happened).
Since you have a sprit and a hound, you could easily add a screacher...however, you should know that a screacher/code zero is hard on the boat/rigging. I broke the bow off my old trimaran more than once using a screacher. Part of the reason I went the windseeker route is that fact...since I won't use it in big wind, I won't have to worry about breaking the mast or the bow spreader.
