Blood Sun

Things are beginning to heat up in Bermuda with the new America’s Cup catamarans practicing ahead of next months round robin sail off, followed by the Louis Vuitton Cup, and finally the 35th America’s Cup between the Louis Vuitton winner and Team Oracle USA. If you search myislandhomeBDA at Youtube, [...]

Boat Name and Logo

The port outboard hull side received a coat of arctic white with a little dark blue pigment in it. I’m not sure how much difference it will make compared to the cabins and deck which are untinted. The crease in the hull at the sheer automatically creates a different shade of color between the cabin [...]

Attacking the Topsides

It was possible to make a time lapse video with a couple of problems. To get the mast and crane in the pictures, I shot in portrait mode. Plus I was using Canon’s “L” size for the photos. The video application is looking for landscape mode and a smaller sized frame. So, the video comes out [...]

furball Catamaran Dinghy

Richard and Gill launched their little catamaran dinghy that Richard built from plans. They named it “furball”, as that which is spat out by the larger cat-amaran. Here is a link to more photos of it:

Capn Andy/mild winter
Webb Chiles is off at sea again, rounding the Cape of Good Hope in Africa and heading up North. Here is his yellowbrick tracking site: https://my.yb.tl/gannet. I noticed that he has fired right out of the gate with a couple postings of 8 knots plus, in a 24 foot boat.
.
I made a jig out of a short piece of cedar stringer stock, about 4 inches long. I cut a rabbet and drilled a couple of holes in it to use as a drilling guide. The rabbet holds the jig against the edge of plywood, and the holes, 3 inches apart and 5/16“ from the edge, are used to drill the holes for stitch and glue construction. One hole has a sheet rock screw partially threaded, so after you drill the first hole in the plywood, the tip of the screw is centered in the hole and the remaining hole in the jig lines up your drill for the next hole in the plywood.
.
After drilling the holes (50), I used some donated solid copper wire, about 18 gauge, to twist and tie the panels together. Only the keel edges were tied, the bows will be done later. I used 5mm ply to cut out three bulkheads, one for amidships and two 3 feet forward and aft of amidships. The bulkheads were temporarily pushed down into position, forcing the hull into shape. I had to get a look at it.
.
Next I cut out butt blocks, more like butt plates, 4 inches wide and extending from gunwale to keel. Two plates to each bulkhead. They serve to spread out the pressure of the bulkhead against the hull side so that the hull side doesn’t have its ribs showing. At the amidships bulkhead I added 3mm thick hardwood splines that ran fore and aft across the edge of the bulkhead to keep the hull sides fair. They were about 8 inches long and bisected the butt plate into two smaller plates on each side of the bulkhead.
.
The whole shooting match was dry fitted with a hole drilled just under the gunwale on each side of each bulkhead, dynema string threaded through the holes and over the top of the bulkhead in a figure 8 loop, and the loop tightened with a spanish windlass, forcing the bulkhead downwards, and pulling the gunwales up tight against the bulkhead edge. The positions of the butt plates, splines, and bulkheads were marked and labeled so that they could be reassembled for the final gluing.
.
I had expected the seam at the amidships bulkhead to need trimming, but it wasn’t necessary. A mix of epoxy was brushed onto the gluing surfaces, then mixed with “glue strong” filler and applied to one side of each glue joint. My mix for “glue strong” is 4 parts of colloidal silica to one part of milled glass fibers. The pieces were assembled again and the spanish windlasses were wound up. The pieces were finally tapped into position with a small hammer. The joint between the bulkheads and the butt plates was filled with the epoxy mixture. Later they will get filleted when the keel and bows are filleted.
.
The photo is of the midships bulkhead. It has the spanish windlass of blue dynema line over its top and the white piece of wood used as a handle to wind it up is there with a clamp to keep it from unwinding. The butt plates and spline can be seen jammed against the hull side by the edge of the bulkhead. The pencil line across the bulkhead is the normal gunwale height and it intersects with the gunwale on the right. The gunwale on the left is higher, raised so that the deck will have an angle to match the crossbeams, which curve downwards to the ama. This picture was taken while dry fitting the bulkheads. Later they were glued in permanently.
