The val IIIs looked fast. There was also a constant camber version of a val/tremolino that was 30' and folded for transport. I bet that design is still fast by today's standards.

Cirrostratus 10m

These drawings came from this site:
http://www.multihull-maven.com/Boats/Cirrostratus_10
Check it out there is some interesting ideas on this boat, notably the wishbone cutter rig and the bomb bay doors behind the forestays which store the hanked on headsails below decks. I also like the central position of the motor. Not so keen on the twin cockpits but with the aft cabin I guess you can't have everything !

"Wishbone cutter rig"....I had to look back at my old submission to Multihulls mag and Rudder mag to see if I had adopted a wishbone boom for my mizzen sail on my cutter-ketch arrangement.

1974-75
http://www.runningtideyachts.com/archives/OrgMagArt.php

1974
http://www.runningtideyachts.com/archives/Ruddermag.php

Turns out I had not yet adopted that boom arrangement in the original concept?

So what did I come up with? Lets call it a marriage between a cutter and a ketch without the mainsail. The original design was published in Yachting 1974 and in Multihulls 1975. Rudder magazine also made note of it in 1974. It was "A Unique New Cruising Rig", designed to go on a 55' cruising cat I was working on at the time. It didn't get built and neither did the rig. Like a bear, it went into hibernation.

Didn't one of the early eighties English trimarans apricot or paragon use a form of bomb bay doors to assist in head sail storage. As well was there a problem due to the fineness of the main hull.

A write up by Derek Kelsall about the trimaran Toria's success in the 1966 Round Britain Race. Scans from the November 1966 edition of the Trimaran Association of Australia newsletter.

A link to a delivery of Moxie to Europe which ended in the Azores.
http://www.wingo.com/newick/moxie/index.html

And a very vivid recollection of that trip by Lia Ditton, who was one of the crew on Moxie on that delivery.

there was another Cirro

I had a fair bit to do with Robin - I built one of his boats.

XS had no problems going to Antarctica - Robin and Terry got very cold. Terry couldn't fell his fingertips for a couple of months afterwards. As far as I can recall the motor fell off its mounting hinge and trailed by its cords. The boat got absolutely hammered by amazing katabatic winds that they ran away with just before landfall. They were in sight of land all day but never got to set foot on Antarctica. Robin has done heaps of miles and it was some of the worst weather he has seen.

There was a larger Cirro - Twisted Sister was an 11 metre version. Basically the same. Cirros would have more room than a Newick of the same length but the Newick has a really nice cockpit.

The bomb bay doors were on Irens designs 1986 designs as well IIRC. They were replaced.

I scanned this from an 'primer' on how to race multi-hulls. No. 127 is the one I owned for some years...some years ago.

Do you remember who designed the Cougar? It seems to resemble a MacAlpine-Downey design like the Thai Mk 4 or Shark but its not listed under his designs that I can find. Thanks for the picture and info.
