I recently rigged my boat with a spinnaker and it's been a learning experience for sure. Here's an example: I am headed upwind for the windlward mark and as I tack over onto starboard to lay the mark the crew gets off the rail and begins the process of readying the spinnaker for hoist. I have found that all of the this activity slows the boat when sailing close hauled as compared to when the crew is sitting still on the rail. My solution to this has been to slightly overstand the mark by a boat length or two so I can come off the wind a little bit. This mitigates the affect of the crew moving around and I sail faster. Anyone else do this? Am I just being an amateur?
