    Ordering new sails - set wind speed?

    Absolutely always talk to your sailmaker about the conditions, both wind and waves, you want a sail to be optimized for. Also make sure you talk about the maximum wind you want to be able to use the sail in.

    SoCal PHRF Corinthian rating

    While they may not be a bad idea the implementation of the adjustments is terribly out of line. Two Cal 40's; one with a brand new tri-radial dacron main and genoa, and a flat deck furler that has a plastic foil and looses only 4.5' of luff length. The other with a laminate main and genoa with hanks. The Corinthian boat rates 18 seconds per mile better than the other. Does anybody really think you can do anything to make one Cal 40 18 seconds a mile faster than the other one? In the above example I have a hard time believing it would be worth 3 seconds per mile just because the genoa is a bit heavier and maybe a second or two because of the weight of the main. Of course if the laminate sails have taffetas on the outside then probably no difference. PHRF needs to talk to a lot of people and do some serious research about how much the listed items actually increase performance. Then Corinthian ratings could be a good thing.

    I would wait for Ballenger.

    N2E Wx Thread- Could Be Interesting

    Make sure you don't set your auto pilot at 2 in the morning and take a nap. There appears to be some dirt on your route. :-)

    Maibu Return Race

    Anybody going from Newport Beach to MDR and back tomorrow for the race. I’m looking for a ride both ways. Thanks Harry

    Sail: how much is shape and how much is material?

    Shape is everything. How long the shape lasts is determined by the quality of the material.

    Creating performance targets

    We find that if you sail your targets, and your targets are accurate, you will be sailing the correct angle which give you the best VMG. Any higer or lower and your VMG will not be as good. Targets are as much for, or probably more for, proper trimming, crew work and helming as opposed to picking the correct angle. In fact upwind I have never sailed on a really good boat that looked at the Target TWA upwind, we always compare BSP to Target BSP. I also think you will find changing your heading by 1 degree will not give you a .1 knot increase in speed.

    Creating performance targets

    Of course the problem with that is if you have two boats that are the same and boat one sails a two hour race at 5.7 knots while boat two sails the race at 5.8 knots, boat two will be .2 miles ahead at the finish. The biggest problem with having Polaris based on your own sailing ability rather than the potential of the boat, is that when you start sailing better you will have times when you will be sailing faster than your targets. When racing with real targets one of the important things is to not sail faster than your target. If you are that means you are not pointing as high as you should up wind, or you're pointing to high downwind.

    Creating performance targets

    The problem with that is as LionessRacing said, it will be impossible for you to get accurate Polars that are any better than your own ability. While that may be fine for a select few, it is far from optimum for most of us.

    Creating performance targets

    You can get a Performance Package for US Sailing that will have all your calculated Polars and Targets.

    Exp/B&G: Relative Bearing to Mark

    Not sure what you mean be relative bearing but Expedition will certainly display bearing and range to any mark you have in your active course.

    Computer wireless remote screen

    You can also use Ventus PRO. It gives you the ability to view any Expedition data on a smart phone or tablet and also gives you control of some of the most important functions in Expedition. And much easier to view and faster response times than a virtual desktop.
