Was out this past Saturday in the kayak, 15-20mph sustained winds and close to 30mph gusts. Pedal kayak and a power pole helps with the position holding, but I even mentioned to my fishin' buddy that day that it was impossible to use plastics. Fish were plenty aggressive hitting jerkbaits though, so it was alright.
One of the best things I did for my fishing was to stop being such a fair weather fisherman and start braving some rougher conditions, wind and rain. Obviously I'll get off the water if thunderstorms are rolling in, but some of the best fishing I had last year was right before the storms hit.
