Here's some short drone video without sound of Emilia sailing close-hauled with the genoa. Any comments would be welcome as to sail trim.

Hello Johann

Is there no limit to your talents? Not only do you provide us with superb photography, beautiful music, entertaining articles, demonstrations of proficient seamanship - now you are a drone expert!

Frankly your sails look to be pretty well set to me. But then I am not the most knowledgeable at sail trim; I tend to set sails so that they seem "about right" and then play with their trim and see what the speed differences are. 

What speeds were you achieving? And what was the wind speed? (The sea state looked to be moderate to slight to me)

Best wishes


Richard

Hi Johan

I agree with Richard!

Itís great that you keep this thread alive and adding a new feature Ö. Drone footage 😃

This one is great and I think it indicates that a larger head sail than the jib has a significant impact on boat speed - especially in light winds.

BTW, I am thinking about getting a new main and was actually windering whether all the battens need to be full lenght or only the two battens at the top.

I believe the main will actually drop more easily and better when only the two top battens are full lenght.

What is your experience?

I don't know about my drone skills. The only skill I have developed is to bring the drone back and land it on the palm of my hand and that has cost me some blood.

The wind picked up while the drone was in the air which made me realise that I could actually fly it when the wind is 6-7 m/s. Otherwise I would not have dared to send it away. I think we reached 6 knots at the moment.

I think most sail makers recommend only the two top battens to be full battens. The two lower ones are then allowed to follow the shape of the sail rather than to create it. They can then be perpendicular to the leech instead of perpendicular to the mast. My new sail is easier to hoist than my old one.

The great thing about the genoa is the possibilities that arise when you can move the sheeting point. It took me a while to figure out how far out the genoa should be sheeted to make the tell-tales fly when beam reaching.
