MUMM36 ACE First Sail

Sunny and 20 degree Celcius, perfect for the maiden sail on the new race boat.

On Thursday night, the guys got the rig tuned up, boom on, and mainsail on the boom.

Traffic was terrible; took almost 90 minutes to go from Whitby to National.

Carson could unfortunately not be there.

We spent an hour power washing the outside.
I hooked up the many wires for the masthead wind instrument and displays.
They all worked!

It was blowing 20 knots constant from the west.

We hoisted the Dacron delivery main and a #3.
After the hoist we realized that we had forgotten the battens in the head sail.

Going close hauled 30 degree to the wind doing over 7 knots upwind.
The gusts were up to 30 knots, and the boat just took it; drop the traveler and pinch up.
The runners require attention in the tacks and gybes!

We could have used a reef in the main.



Fly Porter

 

I took over the helm at the west end of the lake and we gybed back towards Toronto.
Point of sail was then on the beam.
We were regularly doing over 8.5 knots, and in the puffs we hit 11.2 knots!
Completely under control; AMAZING



This shows the rig well
Blue lines are the running backstays
Grey check stays below them
The backstay is in the upper right
The line in the bottom left in the main halyard holding the boom up

The runners attached where the forestay is attached and keep the rig up.  Tension the runners, and it applies force to the headstay.  This removes any sag in the forestay for good upwind pointing. In the headstay attachment point in the bow is a B&G load sensor.  This interfaces with the B&G instruments and show how much headstay tension is being applied.  Going upwind, we tensioned the runners a lot and the display showed .31   Think this might be percentage of maximum tension.

The check stays run down the mast, under the deck, and up to the cockpit floor to the mainsheet trimmer station.  When the backstay is tensioned, the mast will bend depowering (flattening) the main.  So the check stays will remove some of the bend in the mast to power up the main sail.  This is useful when tacking to power up the main to accelerate.  Once you get up to speed, let off the check stays for pointing.
