Into the Monastery

Every once in a while I will look back at this blog of a year ago to see what I was doing then. I was wondering what the weather was like. It turns out it was milder, no surprise. I was working on the exterior of the boat and building the outrigger canoe.

Bon Voyage Crawdad

The cold snap, which is the coldest weather I have experienced down here in St Marys seemed to persist longer than forecast, about a week. It has been freezing overnight and most of the mornings, temperature going down to 28 on successive nights. This is nothing compared to what people up North are [...]

The Penguins Have Us

The coooold snap that is freezing us to death is only affecting the Keys a bit, maybe ten degrees less, so 50‘s and 60‘s instead of 60‘s and 70‘s, or 70‘s and 80‘s. The Keys and Bahamas are where to be in the dead of winter.

Happy New Year Chart Wrap Up

It is Sunday, New Year's Eve Day, and I have come down with a cold. My chart work is finished. I can't imagine going outside to work on the hull bottoms now. I may run out of paper towels to sop up my runny nose.

When THE COMPUTER GUY was talking to me about running shell scripts to convert old charts I had mentioned I liked to manually crop each chart and save it from the image manipulation program. Every chart. He looked at me funny. The shell scripts are ways to do a lot of that manual data processing and [...]

Sir, Render

The procedure to convert old electronic charts in the tiled .pcx format to charts that newer nav programs can use involves bulk processing with shell scripts. The shell scripts I needed to use are located in a compressed archive called pcx2tif.

Nina and Pinta at St. Marys

Capn Andy/Warm Spring
When I received the various parts, hulls, etc. that became Kaimu, it was on Good Friday the 13th back in ‘01. Easter Sunday ‘02 found me in New Smyrna Beach, Florida, up the mast and repairing the main halyard. A biplane came in over the treetops on shore and buzzed me while I was up there. It was early in the morning. I was wondering what that pilot was doing out early on Easter morning. He was probably wondering what I was doing up on that mast.
This Easter I was getting over the flu and next door they were getting their catamaran lowered from its raised position, which enabled them to repair the rudders and bottoms of the keels. Now in the lowered position they were ready to launch, and eager. In my last post I provided a link to photos of the crane lift, but somehow they were sorted out backwards, so it makes more sense to look at the photo album from the end. It starts with the crane approaching, and so forth.
I needed to put a coat of arctic white on the epoxied wooden portlight bezel, but that wouldn’t take much paint of all. A small batch of paint is about 5-6 ounces, which is about a fifth of a quart. A quart is said to cover 100 sq ft, so a small batch should cover about 20 sq ft. I added the two forward compartment hatches to the paint job. They are about 4 sq ft each side, top and bottom, so the pair of hatches would need 16 sq ft of paint. It looked like a perfect match. I mixed up a batch and began painting, first the inside of the first hatch, then the topside, then the inside of the second hatch, and what?, I was running out of paint after only 12 sq ft of painting. This also has implications on the amount of paint needed to paint the hull sides. 660 sq ft.
The replica ships of Columbus came to St. Marys at Lang’s Marina and we toured them and took a bunch of pictures which are uploaded to Flickr at:
If you put your cursor over a picture it will reveal a descriptive file name, such as, “Pinta view forward”. I tried to get photos of every rigging detail. The Nina replica has been called the most authentic recreation of a Spanish caravelle.
