MUMM36 ZAMBONI Dismasting

ZAMBONI haulout is less than 2 weeks away.

Time to get the mast down.

Phil and I got to the boat at around 3pm and proceeded to remove:

  • vang
  • boom
  • cunningham
  • mainsheet
  • backstay
  • running backstay(s)
  • pole downhaul
  • halyards out of clutches
  • mast displays

Phil and I did some measurements with a long tape measure.

  • 7'-6" from downhaul block to bowsprit block
  • 45'-4" fractional spin hoist
  • 52' masthead spin hoist

We will use these to create asym tack strop (use the pole downhaul to adjust), and figure out our code 0 and potential fractional asym.

Kris and Michael came and we moved the boat over to the masting area for 5:30pm.

John Crawley was there to do measure the boat for ORC/IRC ratings.
In the above photo, the spinnaker pole on the lifelines was used as a reference to measure the distance from the shear to the black band on the mast to determine the height of the main above the shear line.

The mast came down very quickly.

John had to hookup a load sensor to the crane and re-lift the mast to find its weight (138kg) and balance point.  This mast is definitely heavier than the old mast, so we might get an adjustment on our ratings.

We had a mishap: once of the saw horses collapsed and the mast fell to the ground breaking the B&G wind instrument.  Hopefully just the cups are damaged.

While putting the mast in the rack we noticed a stress crack of the mast at the partners:

This will need to be addressed by Klacko Spars who built the new mast 2 seasons ago.
