Sail # 3 - 2nd. test

When I saw the weather forecast said some 8-9 m/sec from SW, I thought "This is good. More wind, more waves. Time for another test."


The start of the trip was too much into the wind, so the first two kilometres was with no sail - or at least I did not get anything from it. Having paddled a bit off-shore, to reach a better angle for using the sail, I raised the sail, and headed off.


I did a few crossings into the wind. As you can see, here the speed gained a km/h or so. I was paddling very light during these three 'legs'. Finally, when I turned at Assens harbour (going north), the speed picked up. I did not paddle at all since then.


0-2 km is where I get some distance from shore, going south.
2-4 km are the three legs.
4-7+ km. When in position from where i wanted to return, I turned the boat, an headed back. For these last three kilometres, I did not paddle at all..!! In spite of this, the speed was between 7 and almost 9 km/h on this last leg. Maybe I got better in holding the mast vertical. Maybe I got a better trim. Wind change, change of course - I do not know.

Videos as evidence :-)







Sail # 2 - 1st. test

After I had tested how to roll with the sail, I was ready for a gentle test. I took place in 6 m/sec westerly wind. A fine direction for testing on flat water, in the harbour of Assens.


The test went quite well. I was able to cut about 45 degrees into the wind. Most efficient was probably from 90 to 135 degrees.



We soon ended outside the pier, getting the feel for a bit of waves - this was not a problem either.



Sail # 1 - mounting.

Putting a sail on our kayaks, has been in our minds for quite a while. After thorough investigating (!!), we chose Flat Earth Code Zero sails.

This photo from seakayakphoto.com He has been a great source of inspiration, to this project.

  

The mounting took place at Jan Senecas place, all four boats more or less concurrent.
