Building a Brown/Bieker Proa: Dry Fitting first Ama Hull Panels
http://proa32.blogspot.com/2015/06/dry-fitting-first-ama-hull-panels.html
Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Thursday, June 18, 2015. Dry Fitting first Ama Hull Panels. I got the bulkheads firmly attached and then moved on to the main ama panels. These were wired together at both bows and then dropped as a envelope over the bulkheads. Some of the bulkhead tabs required sanding to fit into the slots. The glass and epoxy had widened them. Future builders may want to skip glassing the tabs as much of it is sanded away.

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Friday, August 29, 2014. Poster on Proa Roots. I saw this large poster in Hanalei, Kauai. It shows a few proa-like designs and has a map of migration and trading routes. Wednesday, August 27, 2014. After an Absence, A New Clamping System. This Spring and Summer, I spent quite a bit of time refitting our large boat and then I spent some time out on the ocean. I'm back at work now. Task time: 6 hours. Poster on Proa Roots.

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Wednesday, October 29, 2014. Finishing Up Stay Bulkheads. I needed to seal the exposed "endgrain" of all the laminated layers. I decided to try using a slit section of carbon sleeve. The knit sleeves tend to wrap nicely around corners. Here is a shot of the wet-out carbon which took the shape pretty well. I then layed the final covering layer of cloth over the edge of the sleeve. Task time: 5 hours. There will be one ligh...

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Saturday, August 8, 2015. A couple weeks ago I flipped the ama over and started work on the interior. The keel panels needed taping with two or three layers of fiberglass. Fillets were applied to the keel seam and the bulkhead intersections. Task time: 110 hours. Total project time: 770 hours.

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Monday, February 16, 2015. The plans call for four hat-shaped brackets on the back of the main bulkheads to carry the akas. These are simple e-glass structures. Further structural steps on the akas will keep them from laying flat, so these need to be moulded now. Task time: 8 hours. Total project time: 490 hours. Saturday, February 14, 2015. I ended up laying battens on the sides to dam up fairing compound. I then san...

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Monday, June 15, 2015. The new laser arrived and bulkhead alignment has started. The laser makes it pretty straightforward to align the panels relative to one another. June 16, 2015 at 10:38 AM. Im struggling to get a sense of scale. How far above (below since its upside down) the water. One is the horizontal beam? Are the reference lines scratched in my the CNC machine or have you drawn them on? June 16, 2015 at 8:40 PM.

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Saturday, July 11, 2015. The ama has been making good progress. The keel panels went on. Next the seams got cleaned up and filled where the wires had been. The wire holes were closed. A main task before moving on was fairing the chines, bow and keel. Here is a bow filled and capped with a thin strip of glass. I wanted to fully close the seam. Here is the glass draped and partially smoothed. Task time: 50 hours.

Building a Brown/Bieker Proa. Construction of a 32 foot Jester Class Offshore Proa. Sunday, March 1, 2015. I have come across some great discussions of building issues for longevity of plywood boats. The first source is from John C. Harris at Chesapeake Light Craft. A 15 year old CLC Eastport Pram, perhaps oversanded during the build. The second paper is from Jim Brown. And is titled Building for Longevity. From the Searunner Construction Manual. I found this over at Small Trimarans. Carefully avoid any ...
