The America’s Cup racing began with a four race trouncing of Oracle by Emirates Team New Zealand. The Kiwi’s lead at every mark and were able to sail less than perfectly and still win 4-zip. The speed differential between the boats was more marked than the Kiwi’s advantage over the Swede’s. [...]

Pure Sine Wave

I missed out on the final race of the Louis Vuitton competition and it was the Kiwi’s who seemed to have come up with the boat speed to finish off the Swede’s who had looked so fast. The Swede’s had been the only team to dominate Oracle in the round robin series. The talk is that Iain Percy will [...]

Carb Die It

The big day of Louis Vuitton racing arrived with both pairs of semifinal competitors at 3-1 and three races scheduled for each pair. It was possible for both semifinal races to be decided today.

It rained and rained, a steady train of thunderstorms came up from the Gulf, across Florida, and dumped rain and an F1 tornado. There were intervals between the storms when it was possible to poke your head out and do something, then downpours. The starboard upper shroud was relashed, so now all of [...]

I always take it that maybe I’m depressed when I stop cooking or photography. There is also the possibility of manic behavior in the kitchen or behind the camera. When I start picking images off the internet or saatchiart.com, which is also on the internet, and do not capture my own images, or when [...]

It may seem that we are sitting around watching America's Cup boats sailing and not getting anything else done. That is only partially true. The heat wave makes working in the afternoon very difficult, so it is a good time to take a siesta, but on America's Cup sailing days the racing comes on in early [...]

Chainplates

The punch list for getting the rig ready to restep the mast included torquing down the beam mounting bolts and installing the chainplates. It was important to check the beam mounting bolts because the rig pulls on the hulls and if the bolts are loose the hulls can become canted. Some of the rigging cables are cut to fit and would therefore be an incorrect length. The result would be finding out later that the beam bolts need tightening, and whoops!, the sailing rig doesn’t fit anymore.
.
It took 2 days to mount the chainplates, way longer than I expected. One problem was a heat wave, hitting 98 on successive days. The chainplates have bolts that pass through them, then through the hull skin, and are secured with nylock nuts inside. This means a lot of climbing up on deck and then down in the hull to hold the nut with vice grips or a wrench, then going up and down outside to turn the bolt and tighten it.
.
Each bolt in the chainplates is a unique length. Some are passing through several backing pieces of wood, some are passing through a stringer, and all had to be checked for proper fit. My solution was to shove a lot of bolts into the chainplates to dry fit them, then climb up into the hulls and mark in a notebook which bolts are too long or too short. Then go back outside and rearrange the bolts until all were the right length.
.
Next was a trip to the hardware store to purchase 3/8-16 stainless steel nylock nuts, after spending considerable time looking for the ones I took off not that long ago. When the chainplates were removed, they took with them some of the glass surface of the hulls and some bedding compound, probably 5200. This all had to be ground off the chainplates. I found using the multitool with a scraper blade removed the most material the fastest, then a quick clean up with the angle grinder and flap disk made the chainplates look as good as new.
.
Carefully keeping the bolts in order and not mixing them up, Bed-it butyl caulking was wrapped around the bolts just under the head, then around the shank after they were inserted through the chainplate. Next came running up and down, in and out, putting fender washers and nylock nuts on each bolt, tightening it, then moving on to another.
