Cockpit Rim

I decided to go for a fiberglass rim again. This time, I went for fat 10 oz. fiberglass. The stuff is hard to wet out with epoxy, which it drinks up greedily, but I hope it will build the thickness up faster.
I used various rolls of tape to hold the foam down. I used 5 layers of 10 oz. glass, and finished with one layer of 4 oz. It appears to be thicker this time.
I also cut the hatches out today. The usual amount of shaping and correction.

Skeg Control Box

I had tried routing a fancy control box from a single block of wood, but I really couldn't get satisfactory results. I ended up using the box I made according to the plans, made of many little pieces of plywood.
 Filleted & glassed to the underside of the deck. I turned the boat upside down to do this, and made an amazingly silly mistake:forgot that left is right/vice versa when upside down, and installed it on the left side! I was concerned about not interfering with the knee braces, and put it rather far forward. I hope that I can reach it.
Had a little trouble finding where to drill into the cavity, and nicked the box a little. Repaired it with dookie fill, and routed out the hole. Doesn't look bad.

Back To The Deck

My random orbit sander bit the dust. I replaced it with a big, 6" job that has variable speeds, and two diameter-of-orbit settings. I always thought it easier to do a small job with a big tool, than vice versa. The new tool really made sanding the deck a breeze.
Glassing the deck went easily, except for one glitch: I discovered that the 30" glass wouldn't cover the deck the widest spot! I improvised with a patch, that I think will blend in o.k.
I think I may have finally gotten the hang of saturating fiberglass, after five builds. The trick seems to be to saturate the glass evenly, always using enough resin to fully saturate the glass. Whatever it is, it must be one of those "indescribable knacks", because no matter what I read, I had to get the hang of it myself!

Closing The Clam

I did, this time, use the spreader sticks of the recommended size in the hull, after glassing the interior. It may have helped a little, but the hull still shrank.
I resorted to using the spreader sticks, tethered with strings, to spread the hull. Oddly, the hull was wider  than the deck, near the bow. I resorted to using two Big "ol Clamps to pull it back together: 
This time, instead of using the pre-made 9 oz. tape, I made a long 2" strip of 4 oz. glass for the inside seam. The usual scramble to wet it out with epoxy.

Back To The Hull

Opening the slot for the skeg. This was fairly easy to do with the router. It looked straight from the inside, but it looks off from the outside. I think this may be because the strips were thicker on one side, however, when I insert the blade, it looks straight. We will have to see...
Glassing the hull. This time, I tried using plenty of epoxy to saturate. Lots of it ended up on the floor. I avoided trying to "push" the resin into the glass, and there doesn't appear to be any ripples.
I also figured that the only places I ever get any abrasion damage (barring mishaps) are the bow & stern, so I went for 3 layers of fiberglass in those places, the rest is a single layer

The Interior

I decided to do lots of the fairing work with the boat still on the strongback. It seemed like a lot  of work this time around. Strange, how different parts of the project increase or decrease in difficulty each build.
The deck was easy to remove. The hull, of course, wasn't. I ended up having to saw the beam in half again, but fortunately, nothing was glued together this time. I was thinking about saving the forms & strongback intact, but on second thought, the whole thing is too massive & heavy to have lying around. I'll just save the forms.
Lots of grinding, scraping. etc. on the interior. As usual, it got pretty thin in some spots, but I just "went for it" with a 40 grit sanding disc.
I had a bit of a revelation while trying to fair out the ends. On my stitch-and-glue builds, the instructions have you make a fillet, then apply the glass, and wet it out with epoxy. It occurred to me that I could do this in the areas that I couldn't reach, and the thin spots.
Worked like a charm! You can see some haziness where the filler mixed with the clear epoxy, but the whole thing came together well, with few or no bubbles. To think: I had been doing a fillet, then laboriously grinding it back down. I'll probably do this on the underside of the deck, too.
I did the footbrace kit as on the last build. Pretty easy, once I figured out where to put them.
The skeg box glued in. I decided to try to center it  on the keel, instead of putting the whole box through the hull. The string is there to align it to the boat, but I did a lot of adjusting & tweaking to make it look straight. I also put it somewhat forward of where the instructions recommend. 
Glassing the underside of the deck went fairly easily. I used the putty-fill technique as above, with good results

The Deck

My first two attempts at a deck design didn't work out how I planned them, so I fell back on a Big Skunk Stripe down the center:
Still interesting how the size & shape of the boat seem to change with progress. Its starting to look like a short, fat, kayak.

Flipping 'Er Over

I completed stripping the hull, and of course, ran out of strips. I cogitated for a while about whether to get more light-colored wood to match the hull, or get some darker stuff. I went for the darker stuff, because the lighter stuff doesn't contrast much with the basswood.
On the last build, I tried to fair the hull before stripping the deck. I ended up removing too many staples, and some of the forms wanted to fall out when I flipped the boat, causing problems. This time, I rough-shaped the stem & stern, and left most of the staples in. 
The spine, forms, and hull weigh what seems like 100 pounds. I hung all from the rafters, using my roof tie-downs for ropes, screwed hull-shaped wooden blocks to the I-beam, and flipped 'er over.
Now I finally have to decide on a deck design.

Stripping The Hull

The most fun part of the build:watching the strips take on the curve of the forms, and a "boat-like" appearance.
I noticed that this kayak has a harder chine where the bottom meets the sides, so I used two 3/8" strips at that point. The usual mess of glue drips, steps between strips, and Occasional Brute Force. I did some heat bending at the stern, but it was easier than the Expedition Sport's. 
End pieces, using the usual barrage of clamps, tape, staples, heat bending, etc.
I think that the last time I used an internal strongback,  I inadvertently ground the strips down too far, through the masking tape, exposing the form to glue drips. This time, I tried another skinny strip of tape to try to keep the glue out.

Starting to Strip

Milling the strips went routinely, except that I'd almost forgotten how "physical" and dusty the job is. Again, I ended up with strips 3/16" thick, and decided on a 5/8" width this time. I hope that the smaller strips will be easier to twist into place.
I built the "cross trees" and "outriggers" the same way as the last time, except that I bolted the short boards into the platform, and left the long boards loose. 
The first little cheater strips are in place. I finally figured  out to make the second ones shorter than the first, reducing the number of cheaters needed.

Strongback

After doing it both ways, and realizing the ups and downs of each, I have to conclude that its generally easier to get things aligned when using an Internal Strongback-especially the bow & stern sections.
I had to do a little pulling & tweaking on the spine in order to get the centerline on the forms to line up to the string, but it seems to have come out well. I adjusted the bow & stern sections using shims, and held them in place with glue blocks.

Starting In Earnest

It seems strange, how much I "forgot" about building between last year and this year. I tried building an I-beam twice, using dimension lumber, before giving up on finding boards with no twist or warp. I finally went for this "composite" stuff:
It weighs tons, but it appears to be dimensionally stable. I'm doing an internal strongback again, this time, and after doing it both ways, I think that this technique better insures "straightness". 
The "spine". The Strongback Jinx  was in-I made the first one 1/2" too small! This is poplar ply. I found that the forms fit a little too tightly, so I actually ran the whole beam through the surface planer. It was a a little bit too much to handle, so I widened the holes in the forms instead.

Skeg Plans

I decided to build a skeg & housing from scratch. This gives me something to work on & get psyched for the build. I want to complete as much of this as possible before glassing the hull interior, so I won't get hung up in a lengthy process while the hull wants to shrink & distort.
50-page building manual, and lots of small plywood parts, all of which have to be epoxied, and many fiberglassed. I had to order some rather expensive stainless steel parts. 
Nicks plans call for building a closed box, making a hole in the hull, putting the box through the hull, then trimming to the hull. I'm going to shape the box to the hull interior, and make a slot for just the skeg.
I could not get a feel for what has to be done just by reading the manual. I had to get my hands on the work, following the instructions, before I "got it".
After cutting the bottom of of the box, I tested the skeg blade for fit. I broke the hinge. I glued it back together, then broke it again. I decided to duplicate the blade in Lexan:
It was pretty easy to trace from the wood, and I don't have to worry about waterproofing. After some adjustments, it fits fine.

New Things

For various reasons, I decided to donate Outer Island II to a nonprofit organization.
I was in a stressed-out condition for most of the time I was working on it, and it was not my best work.  I somehow managed to feel rushed & driven while working on it, instead of relaxing & having fun. In the end, I just didn't like it.
That being said, I'm using my trusty Outer Island I many times this summer, as usual repeating my favorite trips. 
However, that does not mean that I'm not going to build another kayak! I'm still looking for a smaller "go-to" boat. I looked at Vaclav's Cape Ann Storm LT as a possibility. At 16', even the designer recommends the use of a skeg. I posted a question on the Guillemot message board, and got the usual flurry of responses, and it got me psyched up for another build.
Sometimes, I start a build with a detail, like the carrying handles. This time I ordered Nick Schade's (50 page!) plans for a home made skeg box. 
I guess this qualifies as The Start Of A Build, so here we go! Its only September, I can take my time this time.

Done!

Off to the traditional lake for a tryout:
And of course, the traditional Trophy Shot:


I was actually surprised at how very similar the handling is to my first Outer Island. It may cruise a little faster-it was easy to maintain at 4 mph, and sprinted to about 5. The stability is almost identical to O.I. #1, which was slightly surprising, because I  built it to the design length this time, and I expected it to handle just like Jay's, with the stiff tracking and solid secondary stability. It must be a Mystery Of Kayak Building-how two people can build to the same specs, and build two different kayaks.

Outfitting

Went fairly easily & routinely. The hatches, grab handles, and deck rigging were done almost exactly as the last two builds, with one difference: I made a simple loop on the foredeck for my GPS.
I carved the foam seat as usual. I found it interesting that the side brace foam pads had to be of a different shape and position than I expected, and that the foot braces had to be  extended to the third-to-last adjustment point.
Also, I confirmed that it is the cockpit size, more than the cockpit height, that allows butt-first entry into the kayak.

Finishing

I decided to finish the boat with automotive clear coat paint instead of varnish. I liked the idea of doing all the coats in the same day, instead of a week. I hung it up, because I was afraid to rest the kayak down on new coats of paint. I went through five cans of clearcoat, using about one can per coat. The coats seemed rather thinner than I wanted them to be, but I avoided runs & drips. I hope the coating is thick enough to be sanded & polished out.
Wet-sanding an 18' kayak goes much better when done in the backyard. I sanded with 500 and 1200 paper, then used the R.O.S. with a foam pad-rubbing compound, then polishing compound. It looks more like a semi-gloss finish at this point.
After a whole lotta sanding & buffing, I decided that I didn't like the look that I was getting. I used the wax remover, sanded one more time with #1000, and went for varnish.

Cockpit Coaming

I decided to go for a molded fiberglass coaming. The plans for the Cape Ann came with appropriately-sized strips of mini cel foam. Glassing the deck went well, and I cut the opening to the size of my old templates. After trying a few things, I found some thin, junky plywood for the mold:
This was easier than it might look. I trimmed it down to the height of the foam pieces, and taped the foam down.
Next time, I may figure out a way to bevel the piece of foam & eliminate the gap caused by the curvy parts of the deck. It seemed like a big gap to be bridged only by tape. 
I covered the whole thing with shrink wrap.

The layers of fiberglass. I started with 6 oz. glass-the bias-cutting thing really does help it work around curves. After four layers of 6 oz, and two of 4 oz, I thought I had built it up quite a bit.
After much scraping, grinding, fill coating, and sanding, I trimmed the edge, and tested the fit of my spray skirt. It fit just fine, and the whole thing released pretty easily from the shrink wrap. I gave it a coat of epoxy primer, and several coats of black paint. It was easy to bond it to the deck with dookie.
After some laborious trimming & sanding, I decided that it looked too "sinister" or something, and repainted it my favorite Jolly Green:
As I mentioned above, I thought I had built up quite a bit of thickness, but this came out to about 1/16". It seems strong enough.
The side & knee braces went routinely & well.

Closing The Clam

This was the toughest one yet. "Everyone" says to put the forms back in the hull while it sits after glassing, but I guess you have to do it immediately, which I didn't. The hull & deck mismatched by as much as one inch in places. My Home Made Aluminum Tool wouldn't even stretch it out enough.
I ended up putting spreader sticks across most of the hull. Tape wouldn't hold the two halves together, so I "tack welded" with epoxy. I tied strings to the sticks, so I could pull them out after the epoxy set. It worked!
I used 9 oz. tape to put the halves together, making the usual mess.

Footbrace Stud Kit

Instead of drilling through the hull, I decided to go for these glued-in studs.
Kit from CLC includes some fiberglass tape. Vinyl tape protects the threads. I put them in before joining the hull & deck. It was all easier than I thought it would be.
