I then loaded the board and headed out the 2km to the open part of Georgian Bay. Indeed the wind was weak, and so I rigged the 9.0 and figured I might be able to pump onto a plane. After trimming the sail, putting on my wetsuit and harness, I opened the board bag. DOH! That is why it was lighter than I remembered! Damn I brought the Skate 108 not the Techno 148.
I couldn't face heading back to get the big board (and leave the sail rigged on a rock in the open) so I tried the Skate with the big sail. 40 litres of flotation make a big difference with a 9.0. I never did get planing and the 3 times I had to uphaul were pretty funny. The board sunk to almost waist deep! When looking at the GPS trail, I was surprised to find that slogging is actually faster than walking. Oh well, I hope to get some sailing in the summer.
