In this Page Mast and Rigging topics will be discussed. 

Efaki has a masthead rigging with a Rotostay furling gear on Genoa and a classic slab reefing system in the main. When I bought the boat there were only two external halyards on the mast that I doubled as I made holes on the mast and took the halyards inside. There were no spinnaker pole aboard Efaki (which I constructed myself to the exact length of the J of the boat so as not to have a penalty in the measurement system) although there was a spinnaker track installed on the mast and also a block for the toping lift of the spinnaker pole. The back stay was permanent which I changed to adjustable by cutting about a meter of it's length and by putting a system of purchasing blocks 2 :1 (that has to be renewed to be more useable). The Genoa halyard is installed on the furling mechanism and so it is not user friendly or easily adjustable. I plan to change in the future the complete furling system with a newer one as anyway it shows signs of corrosion due to electrolysis that the boat has suffered in the past as there were no anodes or grounding at all.

Following a tip from the Snapdragon and Mirage Association's journal, I changed the bolts that secure the mast base on the coach roof with eye bolts that may facilitate in the future mounting of permanent or temporary blocks etc.

This weekend I had at last the opportunity to go up the mast and make some measurements. Many clarifications have to be made and will be in a next opportunity (as in these measurements the rigging screws length has been included in the total length of most shrouds) but the standing rigging has the following dimensions:

Total Mast height: 9,77 meters.

Forestay: 10,12 meters (to the up side of the drum of the Rotostay furling gear).

Backstay: 9,89 meters (to the shackle of the tensioning gear as shown in picture).

Baby Stay: 5,48 meters (to deck).

Spreader height: 4,93 meters.

Spreader length: 0,92 meters (each - from mast to inside of upper shroud) 

Upper shroud: 4,60 meters (from pin of mast to spreader) + 5,46 (meters from spreader to deck). 

Lower shroud: 5,37 meters (from pin to deck).


These are the measurements of an older (2002) ORC certificate.
