How close to the wind can your boat sail?
There is a good reason that Manufacturers do not publish an angle at which their boats point. There are a lot of factors that affect pointing ability of any given boat and frankly simply reporting compass angles tells you very little. For example compass angles do not really account for leeway or VMG. For example, in a high wind, and comparatively flat water, my compass readings could be well less than 80 degrees tack to tack, but my best VMG (especially when leeway is factored in)occurs at something closer to 85 degrees tack to tack. In lighter air, like most boats, my Farr 38 has the best VMG when sailed at tacking angles approaching (and in some cases exceeding) 45 degrees. To really get a single number that is really meaningful out of all of this, you really need to collect VMG generated using GPS data synched with calebrated wind instruments over a long period of time and in a variety of conditions. This would produce a polar diagram which of course provides the most useful information about how well as boat sails to windward in a range of conditions. Today most decent sailboat builders publish velocity prediction program generated polar diagrams for their boats.
I also question the data that you have recieved to date. The Pearson 30''s (by which which I assume you do not mean the 303 which does not point as well, or the earlier 30 foot Pearson Wanderers/Coasters which point far worse than the 303 or 30, nor later Pearson Flyers which point a little better especially when leeway and VMG are considered), that I have raced on, have not had a problem tacking within 90 degrees tack to tack so the reading of 65 degrees seems way off.
