Answering Luc's questions:
The other boats in the race were just the average yachts you can find in any (Dutch) harbor. Real racers do not participate in this kind of low level racing. I don't think I saw any yacht longer than 13 meters.

The Balestron rig could be improved: flatter profile, more sail battens. Specially in the jib, that always has a curved forestay on this type of mast. Fixed boom, well balanced twisting fathead mainsail, bigger surface (+ 30%).

I made sketches for a 2 x 54 m2 mainsail rig (schooner rig). This would bring the Texel Rating (TR) down from 115 (present balestron) to 91. The theoretical maximum windspeed for sailing with unreefed sails would go from 20 to 15 knots.
For a 3 x 44 m2 mainsail rig the TR is 96 and the theoretical maximum unreefed windspeed is 17,25 knots.

These numbers are not more than a vague indication because the TR is based on traditional rigs. It calculates the third sail as if it is a (not very efficient) mizzen.

It is a pity that experimenting on the scale of the Blind Date is so expensive.
Small scale models do not reveal the full truth, because the place of the weight of the crew plays such an important role.

On the Blind Date we have to steer with the rudders and the sails. We can not use the weight of the crew.
My main objection against the balestron is that it does not do much for the steering.
So on shallow water, when we need to get the rudders up, we can easily loose control.
The rudders also do work on low speed, for instance half way a shunting maneuver.

I imagine a well balanced proa must be able sail long distances steering itself.
Well trimmed mainsails of a schooner rig could do that job. We also need a well shaped leeward hull.
A Hobie16 comes close to that way of sailing, however it would be even more stabile when the rig was placed on the leeward hull, like we have it on a proa.

This 'hands free sailing' is a very complex game, with waves and wind gusts and the different courses we may want to sail.
One thing I can say is that all forces should be close to the center of the ship.
That is why I want to try masts that tilt toward the windward side, just like the 'natural' angle of a windsurfer mast.

All four 'official' Blind Date schippers were on board, but Henny and Fredjan have sailed only once or twice this season, due to busy schedules. Jan Schippers, the initiator of the Blind Date project has not sailed because of shoulder problems.

The bad start of most other ships showed the low level of the competition. Soon we passed the two yachts before us and then we saw the whole field behind us become smaller and smaller. Some ships had trouble keeping their spinnaker full and we even saw one ship turning over in a gust.

He spent the first five minutes of the race programming his iPhone. After that we found our way with our eyes closed, inventing yet another meaning behind the name Blind Date.

In light winds they are much harder to beat. The course had no legs straight into the wind, so the keel yachts did not have much advantage of their ability to point a little higher than us. (Upwind we sail a 50° angle with the true wind).

Of course they could not find a proper handicap for us. They gave us a handicap that put us on the last position. Modest as we are, we were not bothered by that at all. We had decided by then that this would be a one time experience anyway (these races are held every wednesday evening), because of the lack of competition.
