Upside down!

The boat is now flipped upside down. Hopefully this is the only time it ever ends up that way! :) The first step is the plane down the chines a bit, then to fill any gaps and / or stitch holes. Then, once everything is nice and smooth, fiberglass!

Thwarted again!

...well, maybe not, but it is a good post title... Anyway, the thwart tubes are now installed, but lets back up a bit. After completing the cockpit rim, I planed and sanded the deck and deck-to-hull joint in preparation for fiberglassing the deck. Once that was smoothed to my liking, I rolled out my fiberglass and cut it to fit. I ended up with three sections; one that covered the forward and starboard decks, one that covered the port deck, and one that covered the rear deck. Since I was cutting these pieces out of "extra" fiberglass, it was just easier to do it this way. Here are a couple pics showing the glass laid out:

Wetting this out was pretty straightforward. I started using a foam roller and plastic spackel knife, but ended up not using the roller that much; it was easy to spread the epoxy and work it into the cloth with the knife.

Then, last night, I cut some big holes in the boat! Fortunately, they are above the waterline... The holes are for the twart tubes which provide structural support to the decks and gunwales, as well as holding the akas for the sailing rig. I epoxied the tubes in place and applied some fillets to the inside and outside joints. I also added some small strips of fiberglass tape around the internal joint to make sure everything is nice and strong. Here are some pics:

And finally... I got the rear seat supports dry fitted. This was definately a challenge since everthing is curves and angles. I started by cutting out a scrap of chipboard to the size of my seat. I then laid it in place, took some measurements, and cut out my first attempt at a seat support. After plenty of re-cutting and planing, planing, and more planing, I got everything to fit nice. The funny thing about the pictures is that the seat supports look crooked and out of square, but in fact, they are the only square, plumb, and level thing on the boat!

Mostly finished cockpit rim

Well, the cockpit rim is almost completely done. Since the thwart tubes are covered in this cool looking carbon / kevlar sleeve, I wanted to see if I could find something similar to use as the outer fabric reinforcement on the cockpit rim. After some searching, I found that U.S. Composites caries 4" wide carbon / kevlar tape (all the way on the bottom). So I ordered some, and it is now epoxied on. It happened that it was really hot and humid the day I did this, so I needed to work really quickly. I managed to get everything laid up without losing any batches of epoxy, so I was happy about that. The nice part about the heat was that a few hours later, the first coat was pretty much hard, so I did my fill coat right away. After letting things cure for a day, I am really happy with how it looks. I cleaned up some of the edges with a chisel (the ONLY way to cut epoxied kevlar) and ran a fine grit sanding block over everything. Once the boat is painted, I will add a coat or two of varnish, and it will really glow.

More cockpit progress

I have a couple days of progress to report... I did get the riser filleted and taped, that went really well. I once again used a disposable plastic frosting piping bag to apply the fillet, and I am loving how easy they make it. Unfortunately, I have only one left... need another trip to Meijer! Next, I cut out the coaming flange (flat part). I used my last remaining big piece of plywood, and made the flange out of only two pieces. Tonight, I glued the flange on. I don't have enough long bar clamps, so I resorted to painters tape to hold it down. In a few places, it didn't want to lay flat, so I just layed a couple blocks of wood across the boat to keep everything nice and flat. I also applied a coat of fairing putty (epoxy + microspheres) to the deck and deck joint since I am planning to fiberglass the topsides soon.

And last but not least... I epoxied the cool kevlar / carbon sleeve to the outside of the fiberglass thwarts. The thwarts are hollow fiberglass tubes that will eventually hold the akas when the sailing rig is added. Besides looking cool, the kevlar / carbon sleeve should make them a lot stronger and stiffer.

Cockpit coaming riser

Over the past couple of days I have gotten the cockpit coaming riser installed. I am making it out of two layers of 6mm plywood instead if the designed 4mm. My reason is so that I have a thick enough rim to install some screw-in snap studs, so I need the rim to be at least 3/8" thick. The snap studs are for the cockpit skirt I am planning on making. One of the Watertribe rules for semi-open boats is substantial decking (which the XCR already has) and a full skirt based on the one described in chapter 7 of Cliff Jacobson's book "Expedition Canoeing." Anyway, both sides of the riser are installed now, tomorrow it will be filleted and taped.

Cockpit coaming begun...

Last night I went to work on the coaming riser clamp with a hand plane. The coaming riser should be vertical, so there needs to be a rolling bevel cut into the riser clamp. Working with the plane is always fun, I love making nice wood spirals. Especially cedar ones, since they smell so good :)

After a while however, I decided to switch over to the belt sander with a 50 grit belt which made very quick work of finishing things off. Then the boat went back inside (it was outside so I didn't cover the garage in sanding dust) where I started on the coaming riser itself. I cut some 6" wide "strips" of 1/4" plywood and clamped them with the bottom edge of the plywood just below the bottom edge of the riser clamp. Since the riser is intended to be 2 1/2" tall, I used a pencil and a block of wood to scribe a line exactly 2 1/2" above the deck all around. Tonight I plan to start cutting and gluing.
