Wow. What a simple, straightforward way of demonstrating the forces as you furl. I’d wager it’s actually more helpful than the real thing! I vote for more kitchen sink explanations. “Kitchen Sink Sailing” series. Thank you!
Great clip! Not enough tutorials on YT cover safe and correct in-mast furling. I've already made a similar model to explain it to my ad hoc crew. To get even tension along the luff, I always position the boom to port (with counterclockwise in-mast furling). With a skilled helmsman steering the boat with slight tension, I can furl by hand, but always finishing with a few winch strokes to secure and tighten the sail inside the mast. For those using Selden in-mast furling, I recommend locking the winch at the mast with the ratchet for that extra bit of tension. Last hint, if it is not going according to plan, unfurl and start again...... This is a valuable guide-thanks for sharing!
Thanks Ed. I like to try extremes to help me see what causes problems. Try pulling the boom down far and roll up a little sail. Then unfurl and try rolling it in while someone holds the boom up. You'll see pretty quickly what causes jamming. Now try to find the sweet spot for the boom so the sail rolls up flat. Jamn it no more! 😀
There's an easy way to unblock the mainsail when it blocks unrolling it; just put the boom towards starboard as far as you can, then unroll it. That's all. It will unroll effortlessly
Love the visuals! Super informative. But you use a fair number of terms which I, as a interested but unexperienced sailor, am unfamiliar. Could you please explain some of the terms you used when describing how to keep the sail properly tensioned as it furls?
The 3 edges of the sail are the foot (bottom), the luff (vertical), and the leech (angled). Ideally, you want to keep each of these sides straight as you furl. Loose material, as a result of slack, will fold over on itself as the sail rolls in. This increases the bulk of material inside the mast to the point of overfilling that space, which causes a jam. Also, giving the outhaul a tug a few times as you furl will help tighten the wrap of the sail inside the mast.

About to head out today for the first time with my new boat/mainsail furling; great visual. very, very helpful --- thanks.
