Bram;

I didn't bring up the fully battened/light hull quote, it was Furtive.

Where the quote was and those it was aimed at, it may well have been reasonable - but it WAS there on the site as he had said.

About "As for Huntington Lake:  There was one Asymetrical Canoe and one Swift Solo there--no Mustos, no IC's."

Sorry, I thought Huntington WAS Jericho 2004, where the top SS was beaten by an AC and 3 ICs (according to Bob Lewis and Anders on the US IC site, where I got the two events confused).  My mistake.

About "The only single-handed mono out there that I am not willing to put up money against is the AC (the other three sail single-hander) unless we agree that we will not sail in above 10 knots of breeze."

Whenever I've been able to get what seems to be good info about the relative performance of the UK ACs/MPSs/RS 700s, it seems that they are all very similar in pace in the medium range with the AC possibly stronger in 10-18 or so and the MPS likely better in more than that. Maybe my info is wrong, but it seems fairly good.

Given that the British seem to (generally) find that the MPS and 700 are about as quick as an AC in 10 knots plus, and you imply the AC is as fast or faster than the SS in 10 knots plus..................Hmmmmmmm.

I am of course in no way an expert but surely have the right to raise such matters (when my info comes from good sources ie top Canoe sailors, desigenrs and top sailors of 700s and MPSs etc).

While I happen to love jibs, it IS interesting that some VERY smart designers with loads of success in high-performance singlehanders are agitating to open the Canoes up to cat rigs. I
hope you're right and the sloop is quicker but surely, balancing the sloop supporters against cat-rig supporters like Steve Clark, Andy Paterson, etc, we must allow a lot of room for doubt and this doubt should be aired.

I've never had any trouble understanding your belief that maximum beam is linked to gustiness, difficulty of handling and the number of crew. This concept (in part)  has been mentioned since John Westell's day, and it was very well known back in the '80s in the 18' skiffs.. Other very well known designers have similar objections to wide trap singlehanders.

Despite understanding the concept and respecting those who believe in it, I am not 100% sure it is defintely correct and therefore I felt it was OK to raise doubts about its application.

I just wonder whether the problems with wide beam etc  in gusty conditions (which have never been in any doubt) are enough to outweigh the advantages of wide beam etc  in "normal" winds.
For example, both the Moth and Canoes are  hard to handle yet neither Moth nor (Australian) Canoe sailors find that it is better to give away some of their RM in gusty conditions by sitting much further inboard on the plank or wings. Even in conditions like the Brass Monkey regatta in Sydney this spring (about 50% retirement rate due to VERY gusty conditions) the Canoe that was 5th in the world (last time he raced) and the Moth that was 1st in the world were fully out in the gusts (as far as I could see, I was damn busy racing 'em!). Therefore the world-class Mothies and Canoe sailors feel that maximum RM is the way to go even in extremely gusty conditions, on less stable hulls than that of the SS. If you don't WANT maximum RM, just move inboard - but if you have the option of going wide it seems incredibly valuable.

I'd assume that in the gusty stuff, a top-class singlehander on a trap could have just trapped high and moved onto an  intermediate position like dual world Contender champ Arthur Brett often did.
And  I would also assume that when the wind steadied down, each inch more beam would have been a fraction more speed - no way am I going to go to a shorter plank on my Canoe!

That's the sort of reason I wondered about the relatively narrow beam of the SS. Maybe it's different with traps (which is what Julian says). But the fact that (as I understand it) the MPS and 700 can pace it with the AC in 10 knots + indicates that they DO go very well in often-gusty British conditions. A former world Contender champ reckons the MPS is EASIER to sail than a 14, ergo gusty conditions may not be such a problem for singlehanded skiffs.

I DO (as I said) believe that easing the jibsheet can be very important. So I agree (for what its worth) that your system may well be an advantage.

That doesn't mean (a) we have to just accept the SS system blindly without mentioning that on other craft it has not worked so well (even when I wanted it to!).

(b) that we have to accept that the jib system will be enough to make up for what seems to be (from my non-expert viewpoint) a lack of hiking power compared to the MPS and 700 (which DO seem to be as fast in 10 knots plus as the AC).

I certainly agree with you that the rack may be undervalued, as shown by Canoes and Skates.

Anyway, thanks for the post. It would be fascinating to get all the candidates for the title of fastest singlehanded mono together. I'll have to leave it to others as I'm leaving tomorrow for the first of 3, 4 or 5 national titles I'm doing this season.

You've got the Swifts, Anders can represent the Canoes very well.......just got to get some of the British 700s and MPS and an Aussie or British Moth along! I'd certainly put money on the SS in the light stuff, but the all-round champ.......hmmmmmm.

People like a good contest, there will be eyeballs for this event. This should bring nothing but good publicity even to the penultimate skiff, whatever one that might be. It could be a good crow bar to heighten the awareness of the MPS and crack open the door of the US market where I think it might do well.

I’m not sure I want to mention it and I'm sorry to bring up the semantics thing again but the MPS literature does indeed say the MPS is "the fastest boat of its type" after having raced in multi-boat fleets. Now the Swift Solo has raced plenty of other multi-fleet races, and the MPS.  The SS has consistently won against the MPS, so would that marketing claim on your web site pass your ASA smell test? Currently the SS is the only one of the two with evidence that either is faster. Perhaps you would agree that both boats are the easiest to sail and fastest boats of their type.

Sandy, we love sailing skiffs and if there is a good event looming then we for sure would like to get involved; as for commercial contribution that would be a decision for Victor Boats.

With regards to performance claims we don't lead with any performance claims; you have spotted a bit of copy for the brochure that states what we have evidence for right now and it is clarified. There are many boats of different types that I believe are faster e.g. AC, foiling moth, Tornado etc ...

If a new class comes along of a similar type that we get any resonable data on we would review that claim. One boat racing against another tells you little (probably nothing); you need to compare fleets to remove the crew skill factor which is THE biggest factor in these types of boat.

Anyway ... i think the "my boat is faster than yours" discussion is very dull. If you care ONLY about speed get a multi hull.

regards,

Rick

PS The posts on this thread are getting too long for me now ... if I have missed somthing that people expect me to respond to please pm me ...

I agree with you Rick. This whole thing is getting a little academic and dull for me too. I'm with Michael Jocelyn that these boats are just a blast to sail.

The fight for the fastest is of little importance to me. After some checking, I am way too big for a Moth unless it blows 30 and if it does here, it is more like 10 - 50 and very nasty. I love to build boats and tinker so the Swift suits me great. I also like having a jig and masthead kite.

I have only been out in winds 20+ a couple of times and the boat was easy for me to handle. I think if I had forgot all the hype about how hard skiffs are to sail, I would have had more fun.

It sounds like there is something in the works for this summer so we should leave all the chest thumping for after the races are run. The sad thing is that since they will be on the West coast of the US, I don't think the Ausies and Europeans will accept the outcome. Home turf, not the best in the world, ..... on and on. They'll have to get someone to build Swifts and put on an open race in thier own home waters before they accept the results. Oh no they won't. Just look at the pissing contest between the 18's and Tornadoes.

I just hope all this banter brings more attention to all of these boats and we develope a large group of siff sailors in the US.
Live large, love life, and sail fast.

... As for the claim the Swift is "the fastest single handed skiff available" --I believe that and am willing to put my money where my mouth is.  I would hope that every other skiff class would express their doubts about my statement and put up some money as the Mustos are about to do. 

...production skiff that is faster around the track, get it to Seattle and take some of my money home with you.  We’ll both have a lot of fun and I’ll even put you up and feed you for the weekend (Jane’s a great cook).

Bram,

Good to see someone finally making what is the essential point: that it's the dynamic performance of systems that matters, and that goes for the foils, sails, rig, hull... everything. People become fixated on specifications and lose sight of the fact that sailing is normally undertaken in anything but steady state conditions. The variables of what we blithely call 'wind' alone, ie. speed, direction, gradient, turbulence are in constant flux (not to mention the non-linear response of the sails, mast, rigging, and controls), and therefore so is the required righting moment. As in everything, an 'optimum' exists only for a limited set of conditions, and it is the design that matches the current conditions best and longest that will win on the day. On the Voodoo, we have decided to 'max it' as that is our philosophy and we want to push the envelope. Some guys look at the size and height of our rig and shriek, but they've never sailed a skiff with adjustable uppers and an active rig before.

As to your open invitation, we'll be taking you up on that this summer when we have some production boats. Until then, take care.

Dan,

It's good to hear from you and to see you getting it wet.  We should have a lot of fun this summer in the Seattle / Vancouver area with so many new Swifts coming on line, your boat, and some Mustos.  Single handed skiff sailing is the future of sailing (this statement should be good enough to fan the flamers a bit--don't you think)

I appreciate that you've had the balls to have a go at it.  I'm sure you've also found that S/H skiff design requires new thinking and that makes it an exciting exercise.  I believe that the integrated systems that SH skiff designers will design out of necessity (the mother) over the next couple of years will have significant application to other dinghies.  

I saw that you were going to a on boom cleating system and wanted to share a couple of photos with you.  I had tried the typical head knockers and some other systems but found the one in the picture to be head and shoulders above the rest (these are unside down) It does need to be placed fairly far forward on the boom and the angles from the Fredriksen ratchet to the cleats take some tweeking to get just right, however, once you get it there, I think you'll be convinced. The second picture is an addition to help those with less patience because, theoretically, the angle will be more forgiving. I've not actually sailed with it yet.  If you want to try this sytem the dimensions are in the Rigging Guild on swiftsolo.org.  The second system is made up from Servo cleats with the addition of some 1/8" ID thinwall stainless.  You don't even need to weld the tubing--just slip it over the cut ends of the Servo guides.

Best of luck and I look forward to sailing with you in the summer.  Let me know when you want to come down and we'll put you up.  I do live an hour from Shilshole but I'm driving there most days anyway.

Bram,

It'll be great fun, and don't worry..we'll pick you up on the way to Shilshole.

I have to say I really admire all you've put into the S/S, all your years of experience and innovative talents are there to appreciate. Can see what you're doing with the mainsheet system. We just got ours hooked up the other day so I don't have a closeup, but I think you can se it in the photo. It's similar to yours, except that we have cheek plates with a cam cleat mounted on them so it swivels with the bail. Ours would be lighter and works well so far, but we'll see how it works in heavier air.

You can also see the vang and downhaul led to the racks with bungies taking up the slack.  The photo below shows you the hull underbody. Safe to say we've gone in different directions here, which brings me to another point. Boats are like food: one man's meat is another man's poison and people forget it's all about fun. There is no better or worse for everyone, just individual preference. People should get out and sail as may types as they can, just as they should travel to other lands, experience other cultures. There may well be no place like home, but how boring if we were all the same.

Cheers, Dan

Dan,

It looks fast.  We will have some good fun this summer!

Your mainsheet fitting is the style that I had tried. It is lighter and you can buy it in the store!  The issue I had with it was that I needed to move far aft when it was blowing above 15 before initiating the bear away in order to keep the nose out.  It wouldn't let me do it.  (may not be a problem on your boat but I'd have to guess that it might be).  The problem with my system is that it requires a hard vang in order to keep the boom from rotating (for obvious reasons).  On the other hand, the eccentric cam lever is actually quite light, powerful and simple. 

Anyway, if I can help in any way, contact me at bdally6107@aol.com.  We'll likely bore the crap out of these guys by discussing this kind of detail here.

Best regards,

Bram

The shape of the bottom looks like she'll be blazing fast up wind but you had better get off the bow if you want to turn fast.

I have a kayak I built that has a thin bow like that. I tracks great but turns like the QEII.
Live large, love life, and sail fast.

You're probably right, Bram. I'll 'bow' out now...and thanks for the tips, we'll be in touch.
