Jib trim on a catamaran - tips for upwind sailing

This video is all about understanding the basics of jib trim on a catamaran. In order to get the best out of your vessel you need to understand your headsail. You need to know what sail shape you are aiming for, what leech profile you should have, and what your telltales should be doing. In other words, you need to understand the optimal interaction between your headsail and the wind.

Maybe slightly different sea states but similar angles, the motion appears better than Ruby Rose's Seawind 1370?

[@HH44_OC]

What app are you using to display angles and speed?

[@youngbarnacles]

We have a Sailmon sailing display unit. More info on it and other stuff we use is on our website youngbarnacles.com/boat-systems/

How does your rotating mast affect foresail handling and trim? Best sailing instructor I ever had drummed into our brains about looking for "flow"; air flow around our sails, and water flow around our foils and hulls. You would have loved her. Thanks again!

[@nutsandbolts432]

Great info. However, it seems like most of the information has to do with why a sail is made in a particular way. The only thing we can control is sheet tension, and car position. However, if you had an adjustable back stay, I guess you could add or loosen tension on the forestay changing the shape of the jib a lot. Biggest takeaway, adjust to apparent wind, not true wind.

Oh man that’s some fussy shite lol! Now is I possible to make all these things happen or are there allways compromises? You must be worth a fortune to those race guys!

G'day, great video & my question is also to do with your rotating mast & your display. I too have a rotating mast & have been trying to find a compansator? For my display. I have all Ray Marine gear & they have one but even they tell me it doesn't work so what do you use & where are your wind speed/ direction aerials mounted i have thought about having 2, windward & leeward on the aft corners of the boat so i can just switch to the windward aerial after each tack but this is an expensive exercise building 2 towers, etc & i still don't think I'll work properly. Also what display & aerials are you using, very good. PS. I also have a Catana (custom) the first ever built. It was built while L.C. was drawing the plans for the French production company. Started as a 40 now just under 44. Has had the transoms extended & the bows straightened up. Robbo Gotcha Covered

when you mention 8-10 degrees and for cruisers 10-12 degrees angle on the jib, do you mean that relative to the boats centerline? I love your stuff. technical , and to the point.

What did you do to reduce headstay sag? More shroud tension?

[@youngbarnacles]

To reduce headstay sag we needed to reduce the rake in our mast. To do that we shortened the forestay. We covered what we did in our previous video kzbin.info/www/bejne/d5zSmmSafrCse9ksi=L_Cddps8g-pORzot

Really nice that you don't make assumptions about peoples knowledge. Cheers for the vid.

[@timmitchell8784]

Thank you so much. Great talk on trimming. You explained it so nicely my wife was fallowing and finally understood it.

[@Kingsoly]

Thanks luv your tech videos you make what bends my mind come to simple terms

[@pmorph]

Excellent! I'm going out on my wee Pescott next weekend to practice!

[@roberthauser5635]

Shayne you’re the best! Thanks for sharing!

[@StingrayBay]

Awesome it does make sense! Thanks so much for taking the time to show us all! Love it!

[@simonhantler8062]

thats good info, im learning and the way you explained made sense to me.

[@carlospereira9838]

Thank you for your explaining this in detail. This will help a lot of people new to sailing.

[@mathewmacpherson857]

That was a great video. Thanks for the master class.

[@barilro]

Great job. Thank you
