Cruising On The Clipper

It was a beautiful day for sailing. We sailed with a group of 50 persons today, tacking from Muiden to Volendam with 20 knots of wind.
Then later on the day, we sailed back to Muiden. For this upwind leg we decided to use also this 'watersail'. It is fastened under the boom, to catch more wind. It hangs just above or in the water, so every bit of wind is used.
It was great fun!
