D4 Inside Seams

Day two of the dinghy build started out with me finishing wiring the hull bottoms together on the centerline of the bottom panels. This was much easier than the wiring of the chine edges of the bottom panels and the side panels.

D4 Dinghy Day One

A Wharram Pahi 26 had been anchored in the river nearby the boatyard and was hauled out with the travel lift. I went around to look at it and talked to the owner couple. I was surprised that it had been built in Martinique in 1988. The boat is more than 30 years old.

D4 Redux

The inflatable (deflatable) dinghy I had bought was deteriorating. It had bottom seams separating. It is a West Marine branded dinghy made out of PVC. HH66 is the adhesive to reattach the seams. A friend had a similar problem and bought the same adhesive. I was waiting to hear from him how it worked [...]

The Clincher

We decided to go to Amelia Island for the day, probably to the beach. Our plan to cycle around on the Raleigh 20’s seemed like a bad idea, Bleu can’t keep up with a bicycle for very long and when he quits he quits. So we would walk, where?, Fort Clinch State Park. She has a forever pass for Florida [...]

Zen and Bike Maintenance

Eloisa rolled into the boatyard after a long drive down from the mountains. It was getting cold and isolated up there. I had a nasty toothache and we went to Southern River Walk. Bleu, her black American cocker was showing a bit of plumpness. I had had a sandwich and some wine already, so I didn’t [...]

Sink the Bismarck

I continued reading Richard J Evans - The Coming of the Third Reich. It is chilling to read how a cultured, disciplined country can descend into a horrible Armageddon, not once, but twice, and bring the whole world into wars of might and ignorance. I don't know politics, but this book is a revelation. [...]

Proa Design Pt V

27 February 2013 | Bodkin Inlet/Chesapeake Bay
Capn Andy/winter
The recent winter weeks have me occupied reading information about other DIY proa aficionados. Almost all of the boats are self designs, although there are a few designers offering proas. Wharram is one, and mainly offering paddling outrigger canoes that can have a sail added. Gary Dierking has a line of designs that have been well sorted out. There are no proas that fold up like a folding kayak. There are a few skin on frame designs, and my idea that a flat bottomed design was best for skin on frame might not not be true, but I will finish this one before I try something else. Building a non-folding design is very easy. Wharram's outrigger canoes are suggested for the first time builder to get experience prior to building one of the larger designs.
.
The outrigger float that came out too small would have to be replaced and in order to use the Hulls design software to create a new float design, I had to find out why the scale came out wrong. There is a disclaimer that the Hull software doesn't work properly with “some” printers. I tried redesigning and printing. The scale came out wrong and the shape had large wiggles in it. There is a suggestion to use a CAD program, export the design as a DXF file, and print from the CAD program. I had previously used a freeware program from Bentley to view DXF files and it had a print function.
.
First I had to find out why the scale changed or didn't change on the designs from the Hull application. I found that using the rescale function would change some parameters on the drawing page, but the table of offsets in the data section wouldn't change. Perhaps the “lock bulkheads in Z position” effects this change. When I did that and when I drag and dropped the length on the drawing, the table of offsets changed. The file was saved, checking the DXF box in the save menu, and then loaded into the Bentley viewer. The tabloid printer was used and the shapes printed out with no swiggles and the scale measures out correctly. Now the model can be rebuilt with the proper sized outrigger and we can test it when the weather improves.
