9th May 1999 |
Short rig, 10 to 12 knot wind.. | ||
| Straight from behind. Note the wake. |  |
Beam reach straight towards the camera. Actually planing moderately quickly, but the low rocker means that the bow shouldn't be lifted too far out of the water. |  |
| Photographer (standing on jetty) prepares to jump for it...The rolled up foot of the main can be seen. |  |
The short rig is very stumpy looking - perhaps too low an aspect ratio? |  |
| The boat was rigged with the leech quite open... |  |
The wake seems long and clean. |  |
| Charles Crosby, who gave me a lot of useful second opinions during the design process, made Island Barn S.C. the first stop on his U.K. holiday - two hours before this was taken he was still on the aeroplane! |  |
I think I got the sums on wing angle about right (if nothing else!) |  |

16th August 1998 |
Full size rig, about 8 knots of breeze. | ||
| Upwind - Getting the most out of the boat upwind will be difficult because point too high and you stop, point too low and you're going at high speed with no VMG! |  |
Twist in the rig. The intention is for the head of the sail to twist off readily in gusts to depower the rig. |  |
| Putting the boat in the water for the first time. The wings are folded in, but the rig fully tensioned up. The boat has sufficient static stability not to fall over without the sail up. |  |

Some Off the Water Shots
(Click picture for larger version)
These were taken with the boat on its trailer on the reservoir beach, which is on a considerable slope. You'll notice some rather odd horizon effects!.
October 1999 |
Full Rig, virtually no wind! | ||
| The Mast foot area. Somewhat complicated by the string that holds the wings down. The gooseneck like pivot for the kicking strap takeoff is a Bloodaxe design, and most effective. The short strop and aluminium triangle to keep the bits of the purchase apart is my own idea, and seems to work OK. |  |
String Colours Yellow by mast - Cunningham Pink - Outhaul Blue - Kicking Strap Loose Yellow - Kicking strap coarse White with s/s rings -wing tie down White loose - righting line. |
|
|
Gooseneck Area In order to make the sail roll up neatly there's no luff rope in the reef area, instead just this slider, which was a Caws idea and works well. |
 |
From the Bow. Prodder and lowers keep the bottom of the mast rigid and stiff. Angua Von Uberwald is a female werewolf in books by Terry Pratchett. |
 |
|
General view of Rig controls. The cascade kicker has a jam block on in the middle of the purchase that acts as a coarse tune. Solves the problem of running out of travel on a cascade, and great for easy rigging, but not so hot for repeatable kicker settings. |
 |
From aft. Plenty of room in the cockpit! I think the one wing looking higher than the other is an optical illusion caused by the horizon etc effects, but the wing might be sitting on a righting line. |
 |
|
Working Model Always start with a model to make sure the boat looks roughly like you expect! Its much easier to visualise the look of the complete boat than from a computer screen. |
 |
Design Area The PC, with Hullform on screen, the working model, some reference books, and, as usual, appalling untidy! |
