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.
