Into Panama City Beach

The inlet to Panama City is straightforward, but the little turn off to the left to Panama City Beach is tricky, with the channel right close to the beach and a red daymark warning not to head through what looks like the main channel. The image is of our track into the marina which has its own channel tricks.

Into Panama City

I went below and slept and then came up on the 2 AM watch. The owner who was getting off watch said it was boring. I think differently. The boat seemed to jump to life when I got into the helmseat. We were peeling waves off the bows and leaving them in our wake. I was looking at a peculiar star [...]

Key West North

After our rest stop in Key West we headed out into the Gulf. The diesel generator that wouldn’t start was found to have some sort of starter problem. Either the starter motor was bad or perhaps the battery had only enough oomph to click the starter solenoid but not turn the motor over. We did not [...]

Bahama Track

So we are back in St Marys, back in the boatyard, the gulag. Nothing has changed, still the same boat and no rush to launch. Kaptain Ken has got his boat off the marsh, but now he doesn't have the time to talk. I do the laundry and get a shower. Shave the handsome beard off my face.

Arrival and Departure

I made a concoction out of the last remains of mahi mahi. The mahi was trimmed of any bones and cut into large cubes. It was then browned on all sides in a pan of olive oil and black pepper. Then diced onions, red sweet peppers, and mushrooms were wilted in the pan. The whole mess was added to a [...]

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.
