Julian Bethwaite on Fast Handling

by Pam
With Julian outside Bethwaite Design - March 2012
So, I really wanted an answer to the question in my recent post, Fast Handling vs. Natural Handling, so I asked Doug if he would ask Julian Bethwaite if he could answer it. Of course, he could, and he did!

Julian Bethwaite is the son of Frank Bethwaite. In addition to working closely with his father, he is an extremely talented sailor, and an extremely talented designer. Pretty much all high performance dinghies can be traced back to one of Julian’s designs, in addition to the asymmetrical spinnaker, the upside down vang, and some trapeze thingy. I met him briefly, shook his hand, snapped a picture with him and was suitably impressed with how laid back and super cool he was. Then, we later saw him flying across Sydney Harbor testing out some new rigging on one of those numbered ‘er’ boats. I envy that man’s lifestyle. 

So, here’s the question I asked and the answer I received:

My Question:  Frank's work with the simulator helped him see the difference in fast vs. natural handling. How do you take the fast handling know how on a dinghy and transfer it to fast handling on a bigger boat? Specifically, how does a good dinghy sailor transfer fast handling knowledge to a bigger boat that far outweighs him and doesn't respond to his body movement, and, similarly, how do I apply it to a full rig Laser that outweighs me and doesn't respond to my body movement when the wind picks up?

Julian’s Answer:  Regarding the simulator, the fact you can have 1-2-3 people sailing the same course, under the same conditions and the same people do it consistently faster, and you also have print outs of their tiller movements, their sheet movements and their hiking responses or their preemptive moves, then with some deductive analysis that dad was so good at, the differences and the consistencies in those that do and those that do not, stand out and scream at you.

Then with a tad of taking a "natural" sailor and suggesting "fast" techniques and seeing if there was a corresponding increase in their simulator performance proves the point. As mentioned to get that to come across to on water performance had a few more hurdles to jump, but again, he got there.

Regarding reaction to a boat that may weigh many times more than the crew, like a yacht, I find the biggest issue is being preemptive and also getting the boat in balance. If you know what to look for and again, sailing simulator will teach you that, but so will a good coach, then getting any boat in balance will make it go so much better, dare I say automatic. Regarding yachts, a few years back I sailed on a boat called Occasional Course Language or OCL for short, it was a Farr 40 but designed for ocean passages. Consistently we found the boat had lots of weather helm, and we also found it was not quite stiff enough (taller Carbon mast may have done that).  So we went from a L keel to a T and added 500kgs [1100 lbs] plus we also extended the fin aft at the keel line maybe 300mm [approximately 1 ft]. Moved the CLR [center of lateral resistance] aft, helm went back to a appropriate windward helm, boat went 5 degrees higher and about 0.5 knots faster on average, it just did not slow down.

So long way about answering your question, but that, a) getting the boat in balance and b) being preemptive so seeing the gust coming, luffing before it hits, getting the traveler down before the gust, and then squeeze everything back on before bearing away which is all simulator learning, all makes a significant difference.

My Observations:  If I read between the lines, first, I think if Julian had sailed a C Scow, he’d probably redesign it.  And second, I believe he’s telling me I can learn to sail a full rig Laser in wind.  Not that I’ll be competitive against a big guy, but it should teach me plenty about balance and anticipation.  Doug thinks he can teach me those things so we’ll see how the winter goes.  Of course, it’s always possible that the first face full of freezing cold water will be the end of my sailing until summer.

Laser Cheat Sheet

by Doug
When I was 20 and living in my native Montreal, I bought myself an unusual $1,800 present - a one-way ticket to Sydney. Yes, I was restless and yes, that's what it cost back in 1971. One of my goals was to crew on one of Sydney's famous 18-footer skiffs. But the skipper that I was introduced to talked me out of it. He said, "For every hour on the water, you'll have to spend three hours working on the boat." I asked, "What would you do if you were me?" He paused and then said, "I'd call a gentleman by the name of Frank Bethwaite."
2012 with Frank in North Sydney
Thus began a 40-year friendship with the most remarkable man that I have ever met. Frank was the father of the NS-14, a very simple but wicked fast development class with a small sail and no trapeze. Yet it planed upwind. Every high-performance dinghy in the world can trace its roots back to the NS-14 and, of course, Frank's son Julian went on to design several classes including the 49'er.
2012 Pam with Julian at Bethwaite Design
So at the ripe old age of 20, I became the race secretary of the NS-14 association and a protégé of Frank Bethwaite... talk about luck!!!

1971 Frank and Julian sailing their NS-14

[I took this picture in at Northbridge SC. There's an interesting story behind it that helps explain why jibs are so efficient, and will be the subject of another post. Frank used this picture in his first book High Performance Sailing.] In spite of its high performance, the NS-14 was actually designed for husband and wife crews. So one of the challenges was finding a simple way to set up the controls. Frank had a brilliant solution. For the three wind settings (light, medium, and fresh) he had "datum marks" of one, two, and three red dots on all of the controls. Every NS-14 Frank built had these so that anyone could set up the sails perfectly every time.

Fast forward 38 years and Pam is interested in learning how to race a Laser. We would talk for hours and she would always say, "Make it simpler." So I would write things down - how to set up the controls, the strategy for starting, playing the competition, etc. But it seemed that every time we talked about it, she would say, "Make it simpler." The result is the cheat sheet in the right column which I laminate and give out at clinics. Much of what I know is here.  The purpose of the cheat sheet is to allow anyone to set the controls correctly for all lake conditions and simply focus on boat handling and tactics.  The controls should be the easiest part of sailing a Laser.

A disclaimer: The settings I recommend are basic and have served me well when sailing on lakes in Dallas.  There may be variances that others use that work but these settings should be competitive enough to keep you at the front of the fleet.  Major events like world championships tend to be in open-water and these settings are different.  Coincidently, Brett Beyer has written about this in Frank's upcoming book and he has generously agreed to give his perspective of settings in a future post. Describing my cheat sheet will take several posts - we'll start with the three columns that, not surprisingly, can be traced back to Frank's datum marks.

When you buy a boat, you're really buying three for the price of one, but only one of them has to be fast. For the one that you sail in light air, you have to be smart. Speed without smarts means you'll go quickly the wrong way. For medium conditions, you need absolute speed so you need to be fast. For above a certain wind strength (15 for me), boatspeed goes out the window and its all about conditioning, so you need to be fit. Setting up and racing a Laser is all about being smart, being fast, and being fit.

Your weight determines your strength and weakness. If you do not weigh much, you need to be smart and win the light races. If you're weight is average, you have a chance of winning in all conditions but you'll need boatspeed. If you're heavy, you had better be in shape.

I do not know of any single person who is the fastest in all conditions, so it's best to perfect your own conditions and then be reasonably competitive in the others. For example, a race in Laser world championships will not start in very light conditions (darn!) so I need to be really fast in medium conditions and hopefully fit enough to hang on in windy conditions. My finishes in a 72-boat fleet at the 1999 Master Worlds made this really clear - in conditions under 15 they were 1, 1, 1, 1, 2, 3 but over 15 were 7, 8, 9, 10, 10. I have worked hard to improve my heavy-air sailing but sailors from countries that produce great heavy-weather sailors (AUS, NZL) are now getting really fast in the lighter conditions, as we saw recently in Brisbane. Laser sailing will continue to evolve.

In another post, we'll look at setting up the controls before the start and then going upwind.
