Lowwind alpha at Da Curve
Started to rig the Severne Reflex 6.2 on my 4.00m enigma mast. Why the 4.00m??? Because some asked me to test a shorter mast, also I was curious how it would work. For the iSonic 86 I have found good fins and tuning, sooo chose to use the iSonic speed special W49 combined with the Sonntag Fins GPS_2 28cm (rake 17 degrees)
The first attempts to get away didn't work, it was nearly impossible to plane. One lucky gust got me on the downwind course and soo I went 2km downwind. It took a long time and lots of energy to get halfway back upwind. I got again a little gust and did again a speedrun, maxspeed something like 35kn. I was thinking at this moment it would be a long day, too hard to get gliding and 4 fins + other spare parts in my crashvest didn't make it easier to get going on 64 liter. I guess we had wind inbetween 12-18kn. Later a few stronger gusts, and completly outside the range of conditions the gear worked good. Underpowered it was already fast, I would like to know what damage it does powered up :)
Severne Reflex sails do work with a shorter mast, 6.2 was tested succesfull. I believe for lowwind a shorter mast might be even a bit better, for gusty/stronger conditions I don't know yet. The 6.2 now looked very nice and I guess the sail stretched and settled good. The feeling with a shorter mast was even lighter, more responsive, a bit harder for active planning. I have this feeling with shorter mast lightweight speedsurfers could benefit (because they always should take a smaller sailsize)
The Starboard W49 + Sonntag Fins GPS_2 28cm worked like a dream. The first run I felt it, there was absolutely less drag than any other fin I tried before, it feels rather like 23cm long from "drag point of view". Eventhough the fin is made from 35kn till high 50kn it didn't mather I was mostly under the ideal boardspeedrange. After the first fast run I was amazed and decided to stick by the W49, this limited the number of runs I could do, but it didn't matter to me. Just wanted to get as much TOW as possible on my USM gear.
I tried 2 times to do a good alpha, think that big enough gear + slalomfin would add a bit more speed.
Next time I should try both the 430 versus the 400 in the 6.2 with new downhaul/outhaul/battentuning. It might be interesting to test 430 in the 7.0, however I don't know why (because is everything I want with 460).
The starboard W49 should be tested with a shorter GPS_2, now I used the same lenght as the one foot off. Don't feel like shorter is needed for higher speed, but maybe it does give a bit more speed for a reason I don't know yet. I have been surprised before......
