Agree
Timothy, I too feel your pain - I'm going through it now. Alan gave me a lot of advice as well especially around rig tuning. That definitely helped ensure the boat is doing the best it can. I think the bottom line for us is realizing that VMG is key, the wind varies across the course, the tide varies, the currents vary, and there are lots of things affecting our performance against other boats even directly next to us...
What I've started doing now is focusing on how to make our boat sail its best, ignoring the competition (to a reasonable extent - I still want to kick their butts) and focusing on getting to the mark as efficiently as possible. I focus on finding the best wind on the course (watching the wind lines), finding the pressure, understanding the preferred tacks, and tacking/jibing with the lifts/headers appropriately to make the best way.
It's hard, but at least for us, we're starting to understand at least some of the secrets behind sailboat racing. The realization is just because they (the competition) are doing it that way doesn't mean that we can too b/c everything varies.
I added a ton of stuff to our little boat and figured out I'm going to make myself nuts if I keep analyzing everything so much at which point its not even fun anymore. Now its time to master the controls and be aware of the environment.
Anyways...my 2 cents...
Paul.
