Been doing other things, also a bit lazy in this semi-summer weather we're having in Auckland - but have finished the under sections, coved the insides of frames and have laid up one laminate on the table for the first top section skin.

Looking good so far in my book.. Can't wait to see a video posted of her sailing. Good luck on the continuing work Gary.

Off topic from Sid. New and skinny, square top main for Groucho, designed and being laid out by Stu at Dave Giddens' Auckland loft. The 500mm wing mast chord makes it not so extreme in aspect ratio.

Sid will be tentatively sailed at the mouth of the creek and probably won't go past the harbour bridge for a long time while I learn how to handle the crazy thing. I've no idea how it will perform ... but Groucho's new main (probably way less than half the weight of the old, heavy, Dacron one) will definitely not slow that boat down. Not that there was any stability problems with Groucho's wide beam and foils before.
Proportionately Sid is lighter (maybe all up 240kgs) than Groucho's 650kgs - but Groucho is a monster, longer, has a high Bruce Number compared to the new boat's refined? but smaller area wing. Who Knows?

That looks like some complicated software they use there gary, although the price on the bottom right corner looks good

G'day Gary,

I just found this on Small Trimarans.

http://www.youtube.com/watch?v=-4IUi...ayer_embedded]

I recognize the launching and sailing area as the Broadwater here on the Gold Coast Australia. I seem to remember several posters thinking that "Sid" would be good with a swiveling beam system. Well here it is. Interesting it was designed/built 15 years ago.

Tony

Yeah correct about vehicles and video date, but check the comments section talks about Cliff Roberts' 15 year project.

Wow! Thanks for this, Tony. Manual altitude control on a fairly large foiler is
almost unheard of and spectacular in that it obviously works. I kept looking to see some sort of altitude control system(wand ,feelers) but there was none. And fully submerged T-foils must have some sort of altitude control. Then I saw the writing under the video: footpedal controlled flaps! Very cool! And a very beautiful boat....

Good after noon Gary,

Has there been any more progress on Sid, or have you been busy clearing up other work.

Hi Warwick,
Right now I'm longboarding and straightening the trailing edge. The wing is completely skinned and one coat of paint applied (which showed imperfections), the sheeting and bracing positions have been attached (thimbles glassed and carbon-ed on) - other fiddly work, checking for pinholes in the skin, filling, lightly sanding, also sketching out a (slightly radical) colour scheme.
Before I skinned the central section, I was able reach over at the centre to grip lightening holes and lift the wing up pretty easily onto my knees and wave it about like a giant fan, but now with everything covered, there is nothing to grip. Will weigh it properly once painted.

Wing, almost ready to shift. Working on the short mast, in front, on sawhorses.
Bit disappointed with my 3ox glass skinning, too many wrinkles ... but what the hells, will see if the contraption works first, then, maybe hunt down some 1.5mm foam (does it exist?) to glass laminate ... and rip the old stuff off.
The other jpeg is the canting and swiveling bearing (not the rotting timber brace). Bearing will be glued into the short mast later; there is not enough room to shift wing and folded short mast as one unit around the side of the house - will do that later.
