The Great Race

Results

Word is that it is a course record!

Conditions were generally 15-20 knots from the east. Those that experienced it can give a better indication.

Jack also competed finishing in 2:53:20, about 8th across the line.

Rob Green also competed, however succumbed to the conditions and pulled in to Victoria Point, about half way, after too many crashes.

Markla and I piked on the Great Race, preferring to sail at Lake Samsonvale on the Sunday. We had our own mini marathon that was completed in about an hour. Not much of a marathon so they sent us out again for a course race. I spent the race chasing A's, losing to them upwind (geez they can point), and catching them downwind, (hunting the wind pays in marginal stuff). Markla spent the day in the piss, I think he's forgotten how to sail on flat water since the nationals.

count teh convolutions

bow is to the right in all renders.

the pushrod input is the pair of rod ends in olive colour on the right hand side. the pushrod is not perpendicular to the centreline, hence the rod ends. 

this goes into the first rocker (pinkish). it has the same ratio and phase as the wand lever so the rotation of the bolt at the bow is exactly telegraphed (not sure if this is important, but may help with future development). 

phase can be adjusted on this rocker by spinning (nigga) the on board bolt,  draging the right hand side of the green linkage around that arc track. this is set up for adjustment on the land only. i may add a nob (ur) to the top to make it adjustable from the cockpit. 

green linkage is a turnbuckle that is needed to use the extreme range of the phase adjustment. for minor adjustments to phase, it shouldn't be required, the brown rocker just won't stand up straight. 

brown rocker is the gearing. spinning the bolt drags the input pin up it's track. going up amplifies the signal. it has a rope guide on one side only that moves with the rocker, however i expect it will be able to be adjusted from both sides of the boat, it will just need to remain rather tight, and i may need to make some sort of lead for it. 

next is a blue linkage made from a turnbuckle. this acts as a dial. just before it exits the machine there are two nuts on either side of a plate. these are limit screws that mean no matter what you do upstream, it will bottom out on this plate before damaging the centreboard pushrod. will also be a convenient way to see what the flap is doing. 

bearings are to be pressed in, then retained with worm screws. i have just bought some shock aborbers to add into there somewhere (probably on the pink one, with a screw to adjust lever to for dampening). wand length, bungie and wand stopper will also be run to the tramp, seperate to this machine but equally complicated. 

all plate parts are watercut 4mm aluminium hard coat anodized. bolted to the boat with 5x M5 countersunk fasteners into a carbon channel bonded to the deck.
