Agree I was just curious what the effect of not having the heavy mast installed (especially one that sits way up at the bow) would have on speed. Not much from the test data and fouling on the hull and prop affects speed much more. Carter's Archimedes solar boat project got me thinking in a "what if" mode. Since my 25 plus year old sails are starting to show their age. I was wondering if I remove the mast and cover the boat with solar panels what that might do. 5K$ for a new sail would buy a nice number of solar panels. Of course an ideal solution would be the sometimes promised solar panel sailing fabric but, I won't hold my breath waiting for it to appear.

Your data matches up pretty darned close to what I would expect. Adding weight, while increasing the mass, does not substantially alter the LOA, which is the prime variable in just how fast a boat can move through the water. Acceleration and Deceleration would be affected to a greater degree, but not the amount needed to maintain a certain speed through the water. 300lbs on a 16,000lb vessel, would be so slight (about 1 percent variation in the power required) that your data will be more susceptible to variation in measurements.
As you implied in your comparison to the 2011 data, a clean prop makes a heck of a lot more difference than a few hundred pounds of weight.
