Trikini 23 August 3rd 2003

After several attempts to find a proxy to restore the vessel failed I bite the bullet and in July started work on doing it myself.

One problem was the loss of 2 computer HDD in 95 hours . We had spent 2 weeks converting the paper drawings of the 23 to CAD which was a real project and planned on saturday morning to copy to a CD. Then when we booted up Saturday the HDD was dead. Had a new Maxtor and spent the weekend rebuilding the set up and on Monday it failed. While both WD and Maxtor stood behind and replaced the drives it created a real and a stress factor that took a while to untangle.

With a single box restored and the other two sitting there to be done (and still sitting) we turned back to the Trikini 23.

I first considered a radical redesign. make it a demountable put more sail on a taller mast and make it a mini D racer, but simply put the cost seemed excessive since this is a straigh glass hull andso heavy for its size , then the usage made trailering as easy as the 6.47 attractive, and all the components for the swing wing were sitting here. The mast was in excellent shape. we had both the original 6.47 sail recovered from Bacon and a new 150 sq.ft main off the Trikini Spyder.

I wanted to be able to get out of the rain, take a nap, have a porti potty and some basic electronics aboard. That dictated more of a cabin. Using the wings for a berth rather than the main hull tunnel berth

So most of the plans were listed on the previous page went out the window

We had demounted the ORs , removed the pivots and redon the interior structure.

First major decision was to move the cuddy wing and forward cross arm 18″ forward

The second was to go back to the daggerboard system. The trunk was there but it had been capped in the cockpit and sealed on the hull and foam cored

Third was to move the mast step forward of the Daggerboard Trunk

Fourth was to extend the cockpit aft to the rear CA attachment point , pull the aft cabin deck and extend the cockpit sole through the transom.

Fifth I decided to use the 7 degree dihidral orf the race and not the 5 degree of the 6.47 so use wedges at the attachment points to give a 7 degree dihedral .

So the first work was cutting and chopping and then last week we started putting things together

I have redone the Drawing conversion. This involves first scanning the drawings in sections using a legal size scanner at 200 dpi. The sections are then merged in paint shop pro and cleaned up of background clutter using flood fill and saved as 256 color BMP. I then run the drawing thru a raster to vector converion program which produces a vector line drawing saved as DXF. That is put into ACAD. It is a single lawyer and has a lot of partial lines and missing things. I then set up a series of layers and set up a grid and the lines wanted are traced and then saved. finally the imported layer is deleted. I’ll include some drawings in here. It is quite a project.

Here are more photos taken as we go along
