I agree with AGage who keeps signing in as "sol", if 76T's Defender is included in this fleet all bets are off.

That's the one without the spin ;-) The lobe is ability to chase apparent wind deep. It's still forward of beam at TWA140.

Polar is "raw" VPP output. No runs below 20deg (vs 30 for the IMSYC fleet).

Actually, it's tough to get a spin to perform due to some hiccups in the rule. Not sure if the IMSYC group found/fixed/plugged the holes, but the Lines Processing Program bases weight of the rig assigned to the main (%mast+sail) as .5*foot-length^2 rather than .5*foot*luff... Additionally, the weight of jib overlap doesn't measure in.

This means that you can put a 60m wing mast with no headsail on the boat for "free" apart from higher centre of effort, while a long boom really kills you. Hang a "blade" tacked just in front of the mast with whatever overlap you want (unconstrained by the rules, we'll rig a boomkin) and you have a lightweight rig with tons of power.

Here's the "wide" version of the minimum displacement hull.



The overall flare is a single plane defined by the depth requirement and prismatic coefficient. Bow/stern flare adjusts to meet displacement. A knuckle in the intermediate station ensures convexity with all flat surfaces. Righting moment at min displacement is ~40% more than the min beam version. Submerged hull is identical. This is the symmetric version.

Sorry - a bit heavy for SOL... anyways, you can see I had fun.

Very welcome UC...

Is comments like yours that make it entirely worth the effort to publish - although obviously once written for personal use its not a whole lot more work to make public, but I also want to ensure that others have access to anything I write - I feel such an open policy is the fairest... And if something I write helps me, I wouldnt feel the same if I did well unless it was freely available...

Ideally I would like to make a few of them 'browser applications' so that Mac and Linux users have equal access ;-)

Africa by Sea - Abidjan to Swakopmund


Our exploration of Africa by Sea continues. Next, it’s off to Swakopmund, on the water’s edge of the Kalahari desert. It’s a wind-blasted coast, and a venue of choice for those seeking to set wind-powered speed records. More likely than not, we’ll have to beat into it in our Steinlager II, to finally find some shelter behind the walls of Platz am Meer where there is a marina of sorts. Only 2200nm!
