The onset of the U.S. tax season brought on the worst procrastinatorial tendencies here at Chine bLog Central, causing the main body of the editorial staff to shun the computer for weeks. This ordeal astern, however, I can report, at last, on another day building the Merlin Yawl at the Chesapeake Bay Maritime Museum’s Apprentice for a Day program.
I had left her with just a couple planks in place and returned to find her fully planked, with just some fine tuning of the sheer needed (1 block plane + 2 minutes of work). Inspecting the hull, I found a partial set of graceful, laminated frames fitted inside but not yet attached. Each of these frames for the midsections is a single, sweeping piece running sheer to sheer (see the first image below). They are really an impressive sight.
I briefly got up close and personal with one, in a scraper-and-hardened-epoxy kind of way, before heading to the table saw to start creating the next couple of frames.
Each frame is made up of roughly a dozen 1/8″ strips 1 1/2″ or so wide. We milled them from mahogany.
All these frames are laminated in place, so after slathering each set of strips with thickened epoxy, we wrapped them up, bent them into the boat at a pre-set location, clamped the heck out of them, and wedged everywhere we couldn’t clamp. The pictures give a sense of the process (I hope) and show the results: a couple frames laminating in place, maxing out the boat shop’s clamp supply.

I saw a more recent picture that shows the interior painted, so the building of this great boat proceeds apace. I am REALLY looking forward to the launch in June. We’ll have full coverage here at Chine bLog!
Our friends at the Chesapeake Bay Maritime Museum are putting the finishing touches on some nice restorations (more coming soon and in a recent post), but are thinking ahead to another big one: the bugeye EDNA E. LOCKWOOD.
The LOCKWOOD is 53.5′ in length and is a nine-log boat, meaning her main hull is constructed of nine, dugout, pine logs attached together and given framing and supplemental planking. She was launched in 1889 and restored at the Museum in the late 1970s. The time has come for another restoration. And that means they need to acquire new logs. 60′-ish long, straight, fairly clear, logs, preferably pine.
Do you know of sources, oh readers? Think about it and let the museum know.
Last Sunday I got out to the Chesapeake Bay Maritime Museum again for another Apprentice for a Day outing. Planking was the order of the day, as the lovely Merlin Yawl gets her skin.
I arrived to find the garboard planks glued in place and the starboard first broad strake glued and clamped in. I was pleased to hear that the garboards went on well against my planed keelson, with a minimum of filler goop required (and those spots weren’t mine; that’s my story, and I’m sticking to it!).
The first task was the port-side first broad strake. The prior day’s crew had marked it out, but we started by cutting it (yours truly on the jig saw) and then trimmed it off with hand planes. Happily, my cutting was fairly solid and we had light work here.
The test fit proved fairly successful. Some judicious clamping, pushing, and well-aimed mallet blows, and we liked the look of her. Off came the plank, on went the epoxy, and – boom – both first broads were on.
By this time, the starboard first broad strake had completed its clamp regimen and we could turn to the second broad strake on that side. First we fit a batten along the marks for the next plank, with the batten inside the marks. We then cut up scrap planks to lay between the batten and the first broad strake, joining them with butt-blocks and hot-glue. We then glued on scraps that pointed to either or both the batten edge or a line 3/4″ inside the first broad strake representing the overlap of the second broad strake. By moving this template to the plank stock and connecting the tips of the pointer pieces with a batten, we got the plank outline on the plank stock.
From here, the team split tacks. While some worked on cutting and planing this new plank, I took on preparing more plank stock. And that meant scarfing plywood, something I had not done before. Me and a nice, long plane got to it. It is a little tough to tell from the picture, but the sheets are at a bit of an angle to each other to account for the sweep of the planks. Additional scarfs will continue this sweep; hopefully they’ll get a couple planks out of the completed stock piece (the sheets are fairly narrow).
Finally, to finish this productive day, I went back to the boat and did one bit of final prep for the starboard second broad strake: cutting the gain in the first broad strake at the stem. While a saw cut helped set a nice edge, this was mostly work with a chisel and, for my first time, a rabbet plane. It came out pretty well, I think.
So, another great day as an apprentice. I definitely learned some useful tricks and got practice in areas I hadn’t touched yet. This boat is going to be great and I am eager to see her afloat. Now I have to negotiate for another day or two out there… At very least, she launches on June 8th and I am hoping it will be a fun family outing.
When I have been out to the Chesapeake Bay Maritime Museum I have kept tabs on the restoration of the skipjack ROSIE PARKS. Longtime readers first saw pictures of her in tough shape in 2007 (see right).
By this time last year, there was much better news to report: ROSIE PARKS was well along in a proper restoration. The other day, happily, I found her where she belongs: in the water and looking sharp. Here’s to a great job by the Museum waterfront staff!
You Editor-in-chief here at Chine bLog spent the day over at the Chesapeake Bay Maritime Museum‘s Apprentice for a Day program again today, and, as always, I had a great time. In my haste to get to making sawdust and shavings, I didn’t catch the name of the design [Editor's note added after publication: it is called "Merlin Yawl" and was designed by Kees Prins and Bill Bronaugh] for the boat the program is working on this year, but, unlike most of the others, this is a new design, not a traditional Chesapeake boat with traditional construction. This boat does, however, have a traditional style, but it will be done using lapstrake plywood construction. Today’s focus was the backbone.
Let’s look at the design. She is a bit whale-boatish in appearance, roughly 17′ LOA and 7′ abeam. She is called a yawl and has yawl proportions, but, as is generally the case in small, open boats, she is technically a ketch (mizzen forward of the rudderpost).
Looking at the lines, you can see she’s pretty. Even if she was drawn in 2013, she would look at home a century or more earlier. We here at Chine bLog are generally fans of her basic look: double-ender, plumb stem with a nice round in the forefoot, and somewhat raking sternpost.
When I entered the now familiar building shed, I found the strongback and molds set-up with the keelson laid down and attached to the inner sternpost. One guy was shaping the inner stem. My job was to finish shaping the keelson, then two layers of 5/8″ (I think) angelique plywood [Editor's note: our bad - it is okume] laminated together and cut to shape in plan view. One guy had started to plane the bevels in, and I took over the task today. If you look at the lines, you can see there is a bunch of twist in the garboard at either end, and I had to get the keelson beveled to receive that twisted plank. This is to say, I had to plane in a pretty crazy rolling bevel along the length of the board. You can get some sense of the job from the results pictured here.
We also got the inner stem in (that’s program manager Jenn Kuhn checking it out) and, ultimately, glued it and bolted it to the keelson.
I did the shaping of the keelson from this fitting (at left) to the roughly finished result below. I am fairly happy with the results.
With that done for now, the last prep was cutting the slot for the centerboard. My handiwork here too.
Another guy spent much of the day doing calculations to line off the planking. They will be carrying on with that tomorrow, and I am sorry to miss the task. I got a bit of a flavor of it and picked up some tips. #1 – don’t forget to calculate in the rubrail! They’ll have to backtrack a bit on that tomorrow. I would surely have missed that and ended up with a puny sheer plank.
I tried some new things, learned some good lessons, and had a great time. I can’t wait for round two in two weeks, when planking will be the order of the day! Stay tuned for more on this lovely boat.
On our prior post regarding the Chewonki Institute’s Solar Sail program, our friend Ben Harris was kind enough to provide some great commentary and point out his favorite Chewonki boat, the Crotch Island Pinky. We are posting the photo Ben linked to, the source of which is the Scholarshipwrights of Rockland, which seems to be Lance Lee’s latest incarnation of / successor to / parent organization of the Apprentice Shops he launched over the years. I hope everyone is happy for us to better share this boat, as she is a beauty.
This is a classic Maine fishing craft for sure, so I expect Ben’s description of her, “she was… nimbler to weather, dry, and easy to handle,” stems from some ample development in practice over the years. Thanks for sharing, Ben!
The other evening, the editorial staff here at Chine bLog got flipping through one of the kids’ copies of Ranger Rick magazine, the venerable publication from the National Wildlife Federation. Usually the magazine is a source for pre-teen wildlife education, but this one issue actually contained Chine bLog fodder: a picture of a gorgeous, traditional open boat with a gaff-headed ketch rig. The article discussed a program called Solar Sail, a Maine coastal adventure for teenagers. We had to dive in to this story.
The boat is part of the fleet owned by Chewonki, a one-time summer camp in Wiscasset, ME that has grown into a broader environmental education organization. We know of it first because we spent a week there in fifth grade and secondly because it is just up-river from a former Chine bLog family property. The area is all kinds of mid-Maine gorgeous and the organization well-regarded.

The Solar Sail trip is for girls and boys ages 13-16. It begins with land-based education on sustainability, but then takes to the water in one of these lovely boats for a multi-day camp-cruise from Montsweag Bay to Mount Desert. Obviously the trip is fully “naturally” powered – sail and oar to move the boat and solar for the safety electronics.
We couldn’t find much about the boat itself beyond the pictures. It looks to be about 30′LOA, double-ended, and fully open. She appears to be wooden and has attractive, rough-hewn spars. The rigging looks traditional and relatively simple. I love the plumb stem and raked stern post. Can we convince the kids to join up in a couple years?!
The Chesapeake Bay Maritime Museum has a great fleet and will be the better for adding the restored skipjack, ROSIE PARKS. I have blogged about her before and the museum does a nice job of tracking the update in its blog. I checked in on her while I was there. She’s coming along nicely.
See the “before” pictures in this post from 2007.
It happens all too rarely, but I was able to cash in a Christmas gift and spend another great day with Chesapeake Bay Maritime Museum‘s Apprentice for a Day program. The current boat is an enhanced reproduction (a reproduction with some more modern updates incorporated) of GHOST, a deadrise bateau from about 1920. She is a longtime fixture in the museum’s collection but has not, as I understand it, seen the water in that time. Little is known, therefore, about her performance. She is just shy of 16′ LOA with a beam shy of 6′. In her day she carried a sprit rig with 146 square feet of sail.
I found her reincarnation with two rough side planks clamped on to molds and an oak stem. Her chine logs and transom were in place – check out that upsweep in the chines and the laminated keel – as were the initial stab at that most curious of Chesapeake boatbuilding creations, the chunk bow. Rather than planking the forward portion of the bottom, where planks could get twisted and tricky, the builders took a page from the dugout-builders of yore and carved pieces from solid stock. Arduous, but it did the trick.
Our first task was to fit the bottom-most port side plank (the bottom will be diagonally planked).

Here’s another image courtesy of of Facebook, this one on the WoodenBoat Facebook page: two lovely Friendship Sloops, with full sails set, racing (I believe) at one of last year’s Friendship Sloop Society events. Just amazing boats. Ultimate photo credit, I believe, goes to the Friendship Sloop Society, to which I need to pay more attention.
