(machine translated in 2023) Fins test night
I had agreed with John Munten (NED-30) to test some fins, John was struggling to find the right fin for his Patrick Diethelm boards, I have quite a few different fins, so ideal for testing, John could give me tips on trim etc.
Wind was forecast, West 6. So good for the Grevelingendam. We had agreed around 17:00.

S-Type 104 with RAM F8 6.3
After arrival we chatted and consulted. John has no smaller than a 7 meter for slalom.
It seemed to blow too hard for 7.0, so my RAM 6.3 with S-Type 104 rigged.

All evening briefly sailed with different fins to test as many different fins as possible to get a good feeling at the difference of the different fins under the same conditions. Unfortunately, the wind subsided at the end, but all in all very good testing. Total 7 different fins hazards: C3 Venom 34cm, C3 Venom 32cm, Sontagg SL-S 33cm, Select Devil 31cm, Deboichet SL5 34cm, Select S07 31cm, Select S09 33cm.

This was a very educational evening. We need to do it more often.

Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230

18:00 0.25 hour Wind: W
Board: Starboard S-Type 104 - C3 Venom 32cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) With the Venom 32cm it was nice, board calmer on the water, again no spinouts at all.
18:30 0.25 hour Wind: W
Board: Starboard S-Type 104 - Sonntag SL-S 33cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230

18:45 0.25 hour Wind: W
Board: Patrik Slalom 110 - Select Devil 31cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) Briefly sailed on John's Patrick Diethelm, but since it was very rough on the water and John's foot straps were very large, I did not go too far and certainly not too fast, I was on a 10cm narrower board myself and that was rough enough.
Board feels very light and very direct. I don't think John can sail under this board with this 31cm Devil.
19:00 0.25 hour Wind: W/SW
Board: Starboard S-Type 104 - Deboichet SL5 34cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) Wow, that has control. That SL5 feels much smaller than it actually is. Super, really super rest, downwind through the chop no problem. Walking only height is hardly possible. Perfect fin for Downwind slalom in very extreme conditions.
19:30 0.5 hour Wind: W/SW
Board: Starboard S-Type 104 - Select S07 31cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) Wow, that's unexpected, first time with the S07 31cm. John had already tested it and was extremely enthusiastic. So I too, skeptically on the water and very enthusiastically back. What a top fin, control, rest, no spinouts and still height running too.
20:00 0.25 hour Wind: W/SW
Board: Starboard S-Type 104 - Select S09 33cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) The S09 33cm compared to the S07 31cm is less fine, nervous, sometimes a spinout. Gives less control. It is possible that the S09 was 33cm too small to sail.
20:15 0.5 hour Wind: W/SW
Board: Starboard S-Type 104 - C3 Venom 32cm
Sail: North RAM F8 6.3 - North Platinum 430 - Neil Pryde X9 180-230
  (machine translated in 2023) Again the Venom 32cm underneath, felt good although the wind quickly subsided. Sometimes difficulty planing.
