remasting



Because Jarred had replaced all the standing rigging, from hardware at the mast and the deck to the Dymeema lines, remasting was a moment of truth. Five of those Dymeema lines (forestay to the bow and the four shrouds on the sides) have only a couple of inches of adjustment in them, and those inches are really destined to accommodate future stretch, not past mistakes. And it wasn't just about measuring - each line was stretched after Jarred spliced them together. 

The other three (backstay and running backs to the stern) are quite adjustable so involved less nailbiting. 

Also getting a 100 pound, 37 foot long post that is top heavy onto a specific spot on a floating boat takes three people and some concentration. Even the outgoing tide was a minor factor for the crane operator since the boat was slowly dropping while Jarred attached all the lines. 


It all went fine though, except for the use of a borrowed pole to reorganize a couple of lines that were tangled. 
standing rigging was stretched between a big dock cleat and our truck with a come-along.

about 2000 lbs of tension for prestretching. the rounded plate at the top of the photo is the type of hole that is in the mast, and the spliced line that loops around the eye attached to it is part of what needs stretching. the truck started to slip at this point so Jarred had to put it in four wheel drive, although the e-brake is in the rear and so it's pretty easy to make the truck slide when it's empty in the back.
cleared the light pole by a couple of inches.

mast in place. the forestay and shrouds are hooked up, Jarred is attaching one of the running backstays.
Dyneema lines are spliced around teardrop shaped "terminators" that Jarred made, which in turn are hooked up to turnbuckles which are the only adjustment for length in the system, which in turn are hooked into loops bolted into the hull.
all standing rigging (except the backstay) attached and taut enough to hold the mast up, ready for final tuning back at our slip.
