Your diagram of the dagger board position is in a vertical angle 90 degrees to the water surface, it is pointing straight down. Lateral resistance is 90 degrees to the boat’s direction of travel. Now apply heel. The angle of lateral resistance is pointed more downward, lift is pointed more upward to the water’s surface. The more heel the more the angles change until you capsize and the daggerboard is parallel rather than vertical to the water surface. Now my question, what are the positive or negative affects of these angles? Sailing the Laser flat or some heel? What are these forces doing when the heel angles change?

Found this video to be really helpful. Thanks!

Great video, thanks

Thanks for all the great content, I really enjoy watching all your videos

Your content is good, your illustrations are mostly good… sometimes takes a minute to understand what view you are showing. Please try to eliminate um’s and uh’s … they are 20-30% of the words you say and promote sleep.

This videos are _so_ good, thank you!

VERY nice explanation, thanks mate!

With a more rounded shape you have more power and more heeling power so until the main start bulging you can sail closer to the wind to keep a flat and balanced hull

Really insightful- thanks for producing these videos!

Do you have any videos about reading the wind or gusts?

Thanks for posting. I always thought you should keep the boat as flat as possible but that 5-10’ wiggle room is a good idea.

Sweet

How can we get the slides?

Thanks for putting this together. Very well explained.

A polar velocity diagram would be clearer to explain. 🤔

You put so much effort into your work!

Really great talk Maura! Very on point and aimed at sailors!

Thanks, very clear story, very useful

Great lecture today , thank!

C’mon. 30 mins of prepping your illustrations please.

Work on less “ummm”s and “ahh”s when speaking.

Could you do a video on torquing?

These analysis videos are gold man!

Thanks a lot. Your videos are supporting me too much. 🌹🌹🌹🌹🌹

Good stuff!

Very good explanations and illustrations. I learned a lot! Thanks!

What advantage does this provide? Is it like a quick pump of the sheet? What happens if this occurs while going up and down waves?

Well done! fantabulous explanation and video taking..... the finger positioning is really good for us viewers..... keep the good work up

Brilliant session, Sir!!!!!!!!!!!!

Thanks for uploading it folks as I missed you last night. Super useful resource!

very useful video. hope to see more. thanks Ian

Thanks for taking the time to go through this.

These are really interesting and great videos, thanks for posting them!

At 1:05 what I said was a bit misleading. With Rules 13 and 18.2, the tacking boat has to be able to complete the tack without the starboard boat having to alter course at all to avoid breaking rule 13. Then after the tack is complete the starboard boat must not have to point above close hauled to avoid the boat that tacked rule 18.3.

Ian I like your video. Could you please make a video on main sheet management, how to sheet in quick, how not to get it tangled up, where to keep it, I waste so much time on keeping it towards the bow...

Next video. How to replace a radiator

Came here to learn sailing rules in Swedish. Did not disappoint.

At 3:49 I said “Green is definitely ahead of Red”, I meant to say that “Green is definitely ahead of a line coming off Red’s transom”. If this was a race, Green would be behind red at that point.

You should totally add those variations Ian! I'll try the opti hop, it seems harder but I'm always willing to take up a challenge. By pre roll do you mean heeling to leeward in order to get the boat to head up, before heeling to windward and getting the boom across?

That's a blast from the past... little Max went on to make the Candian national team! There are several variations that I would like to add to this video as the sport has progressed in the last 6 years and I have learnt more through sailing and coaching, but one important change is that if you have the coordination, you should not put your back foot across the hiking strap before the tack. New talented sailors from the Opti class have brought the Opti Hop with them. If you can jump across the boat and land with both feet in the hiking strap you get twice the power and it is probably better for strain on your windward knee, but it is significantly more challenging. Also pre-role in light wind is back in style and is widely used.

I wish there were more videos like this. Anyway, thanks for sharing! Gotta love the commentary

Ian, this is by far the best explained and detailed video on roll tacking, I think you don't get as many views as other videos because they have fancy editing and music, but your explanation is more thorough.

Thanks!!! Yours videos really helped!

One of the only laser sailor who play the main.

Thanks for sharing!

Thanks for the videos, you are great instructor.
