Lowwind alpha at Da Curve

Latest session on Da Curve: http://www.gps-speedsurfing.com/?mnu=user&val=65518&uid=870 was again a nice one, a new PB on Alpha. This time I forced myself to use the Severne Reflex 6.2 instead of my favorite sail the reflex 7.0... Only way to do soo was to keep the 7.0 onshore, when we arrived with the boat at Da Curve I had little regret by not taking the 7.0 with me.

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 :)

Gear impression:
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.

Some thoughts:
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......
