This is our new mainsail, designed, built, and
delivered to us in Mexico by Dave Benjamin
of Island Planet Sails. My biggest concern ordering this new sail was that it wouldn't solve any of the poor sailing experiences I was attributing to our old mainsail, that my lack of knowledge about sail trim was the real culprit. So I was very pleased when we sailed with this for the first time and realized a HUGE improvement. We have about 1,500 miles on this sail so far and it is doing well. |
It occurred to me that many non-sailing folks—and maybe day sailors—assume that anyone who casts off in a well-provisioned blue water boat is at the top of their sailing game, that they have tens of thousands of miles under their keel and are able to squeeze the last tenth of a knot of boat speed out of any point of sail.
This past week, I came across a classic DVD stowed aboard that I’d never watched: The Shape of Speed. In it, Lowell North and his friends (a Who’s Who of sailing luminaries) go over strategies for trimming the mainsail, headsail, and spinnaker. The audio is clear and the supporting video footage is excellent. The onboard presentation is calm and matter-of-fact, and often using the words basic and simple. I don’t think I understood 50% of what they said.
When we raise the main aboard Del Viento, I’ll trim it using the mainsheet and traveler car—not using any proscribed formula, just doing what I need to do each time to position the boom for the point of sail, eliminate any sail flapping, and make sure that the shape is pleasing to my eye.
According to The Shape of Speed, a sailor should move the mainsail’s point of maximum draft (measured by a percentage of the chord length) by taking in the outhaul, easing the baby stay, tightening the running back stay, and adjusting the cunningham so that it is not too slack and not too tight. Then one should sight the top batten from the edge of the boom and use the mainsheet to address too little or too much twist. Then it’s best to use the leech telltales for more precise trim. Oh, and “in puffy conditions, the traveler must be tended constantly.”
Whew! Where do I put my beer while I do all of this?

There is nothing wrong with knowledge, and for skillful sailors—racing sailors for sure—all the information related in The Shape of Speed is second nature—and they go fast. In fact, the more of this information any cruising sailor knows and can put to use, the better. But it just isn’t necessary to make a passage, or to cross an ocean. Like Del Viento, many cruising boats don’t even have much of the equipment aboard to effect the basic sail trim described by Lowell North and his friends (no adjustable back stay or second car on the genoa track to adjust sheet leads).
To the hopeful cruiser I say: don’t be daunted by too much information. Like many pursuits, sailing can be as simple or as complicated as you want it to be. My instructions for someone with cruising dreams begin with learning the basics of theory and terminology (even from a book, like I did) and then:
- Sail in all types of conditions throughout the year (warm weather, cold weather, light air, during small craft warning, with sails reefed, in the rain, in the fog, at night, overnight) until you feel comfortable heading out. Because, as Capt. Ron said, “If anything’s gonna happen, it’s gonna happen out there.”
- Practice anchoring and docking.
- Know your boat’s systems and have the tools and spares aboard to resolve the common problems.
And be open to the unexpected events. They’ll come in time—and maybe scare the heck out of you when they do—but you’ll learn from them, exactly what you need to learn. With experience, you’ll gain the confidence to expand your comfort zone and be in a position for more challenging unexpected events, thereby further increasing your experience and confidence. You may never learn precisely where your mainsail’s maximum draft should be, or how to get it there, but you’ll be ready to cross oceans.

As Bill went by, the captain came out from the bridge, at least 12 stories up, to give a wave, probably because we headed up to let him pass. |
Miguel, Very well put regarding sail trim. I spent years racing (even got to race with Lowell North once) specifically to learn more about sail trim and I'm still learning. Most cruising boats are not set up with all the bells and whistles to take full advantage of sail shape and that is as it should be. Most of us are cruising to enjoy the adventure and lifestyle. As you've indicated, one of the beauty's of sailing is the opportunity to learn more about the sport, which serves to enhance the experience. Cheers to the crew of Del Viento.
ReplyDeleteWe try to race every week so as to learn as much as we can about sailing and about sail trim. Its been enlightening. Comically, our boat doesn't even have a traveler. Only a main sheet that just goes to the boomkin.
ReplyDeleteI am a cruiser, not a racer. I have often said that if you spill your beer, you are sailing wrong. Great post.
ReplyDeleteI love the picture of your girls and their new friend. A story in a photograph. And great support for your premise that sailing is probably not the Most Important Thing.
ReplyDeleteGreat post! Since we're just learning, this is encouraging to read!
