Having previously used the starboard side planking as a template to draw and cut the port side, fitting the port side planking was relatively quick and simple. Busy days full of other obligations have meant that I’ve had to work on the boat incrementally... 20 minutes here, 45 minutes there... but, its getting done.

Thanks to a little help from my daughter, I’m now most of the way through driving the screws to hold the planking down. The new DeWalt titanium drill bits I bought have been a real pleasure to work with, particularly since my older ones had become almost too dull to use.

Dry-fitting the forward port side planking.

February brought with it an unusual amount of snow this year. In addition to school cancellations, there were a few days when I got snowed-in at home. I took advantage of these days to draw out the construction drawings for my Zip on a big sheet of eucaboard.  I drew the frames out as they would overlap one another, based on their shared x,y axis & set-up level. This will be a great reference for checking  the frame parts for accurate shape & for assembling the frames. It is also a very useful tool for checking the relative dimensions of various aspects of the hull.

Last Christmas, I received a copy of How to Fiberglass Boats, by Ken Hankinson, along with the accompanying DVD. I finished reading it recently, and I’ve enjoyed watching the DVD. It’s useful information for those, like me, with minimal experience at working with fiberglass. It takes a lot of the mystery out of the process, and its very helpful to watch someone else actually doing it. 

Additionally, the book is very enlightening about precautions to take when working with epoxy.

With any luck, Ill be able to fiberglass the Utility’s hull before summer.

G9 minus nine

Nine days to go until the G9 Boatbuilders Gathering.

Im waiting on my order of epoxy to arrive.

Todays progress: I got the transom and quarter knees drilled for the transom handles that came in today, as well as the cleats I bought at the G7 Gathering. The transom and the quarter knees still need to be varnished before I attach these items permanently.




The transom handles are Sea Choice 6", chrome-plated zinc. They are attached with stainless steel #10 1-inch self-tapping screws. I dont remember the brand of the cleats... possibly Sea Choice, also. Theyre the inexpensive variety, probably chrome-plated zinc, also. They are attached with stainless steel #8 3/4-inch self-tapping screws.



The other item that came in today was my pair of Perko bow chocks. I was very pleased to see on the packaging that theyre made in the USA.

Epoxy work on seats sheer and Zip parts

The last post left off with my having cut out a piece of Meranti for the rear seat. This weekend, I laminated that onto the A/C exterior plywood... and did a little more epoxy work along the way.
1/4" Meranti top for the rear seat
Just as Id done with the front thwart, I coated both mating sides with epoxy (not thickened), and held them together with concrete blocks and weights while the epoxy cured. I had just enough epoxy left over to also add a 2nd layer to the Zip transom knee.


Laminating the Meranti onto the rear thwart. I used the extraneous epoxy to encapsulate the underside of the front thwart, as well as the transom knee for the Zip.
Regrettably, however... after the epoxy cured, there remained a small gap.

And a dust bunny got stuck in the epoxy on the Zip part.
All this didnt go perfectly according to plan. After the epoxy had cured, I found a gap between the two layers that would need to be filled. Also, some dust had gotten stuck in the epoxy on the Zip transom knee. I am trying for substantially better fit and finish on the Zip, so I sanded off the dust bunny & planned to encapsulate with a third layer.

Logistically, I thought it best to encapsulate the undersides of both seats next. This would be the 2nd coat for the forward thwart. I planned to tilt the rear thwart just a little so that epoxy would run into the gap and fill it. Since I havent trimmed the Meranti top yet, this should help the epoxy flow down into the gap. With the extraneous epoxy, I planned to encapsulate the underside of the sheers on the aft third of the boat, as well as the Zip part.

I ended up having more left over epoxy than expected. So after quickly cleaning them off, I also encapsulated part of the Zip stem and the forward face of frame 5-1/2.


More encapsulation; trying to fill the gap on the aft thwart. Here it is propped up slightly with a scrap of mahogany left over from the quarter knees.

How Many Kayaks Are There

I lifted this photo off facebook.  It shows a bunch of kayaks and canoes all rafted up together to set a Guiness Book world record.  The photo came with the following info:
"The largest raft of canoes and kayaks consisted of 1,902 boats and was achieved at the event "One Square Mile of Hope". The event was sponsored by the Central Adirondack Paddlers Society, and took place on Fourth Lake in Inlet, New York, USA!"
The photo got me to thinking, how many kayaks are there in the world right now?  Probably lots and lots, maybe even millions, thanks to the miracle of injecting plastic into a mold.  This is not intended to be a slam on plastic kayaks by the way.  Even home built skin on frame kayaks in the world right now must come close to the number of skin kayaks that existed at the peak of population in the Arctic. 
Aleut population at its maximum was estimated to be about 20,000.  Perhaps a third of that population was adult males each of whom supposedly had a kayak. So at its peak, there were perhaps 7000 kayaks in the Aleutians.

Completion of starboard bottom

June is upon us once again. I have now been working on my Glen-L Utility for just over two years. A good two years it’s been, too. The little boat and I have both come a long way, in many regards.

I’ve just completed planking the full length of the starboard bottom. It’s neat to think that a year ago, I was installing the sheers.


I should be able to start dry-fitting the forward port bottom this week. My goal is to have the boat fully-planked by the end of the month.

As always, time will tell...



This is what the boat looked like 1 year ago. The sheers had just been installed, and fairing had not yet begun.

Initial fitting of the butt blocks.

Butt blocks dry-fit with screws.

Butt blocks epoxied, screwed & clamped into place. Putty knife at the ready.

Epoxy squeeze-out like this will create a fitting nightmare if you let it cure this way.

Thats what the putty knife is for. Scrape it away before it cures.

Aft section battens & butt blocks drilled & ready-to-go.

Aft panel drilled & ready-to-go.

Starboard bottom, fully planked.

Warm greetings from Barnacle Mike’s crowded little boat shop. You know, one of the great things about the boatbuilding community is the fact that you meet some really cool people, both online and in person. The level of support and insight that you get from more experienced builders who kindly share their knowledge and give advice can truly help a newbie keep pushing his or her project forward. I’m very thankful for that.

An online boatbuilding friend, who has also been kind enough to follow my blog, sent me an e-mail the other day asking about the status of the Utility. It does seem like I’ve been paying a bit much attention to the Zip project lately. Truth is, I have still been slowly, slowly... s-l-o-w-l-y... fairing away at the Utility all the while. Still, his inquiry about its status gave me a little more motivation to get off my “transom” and put more elbow grease into getting the little boat past the fairing stage. (Thank you, Paul!)

So, that’s just what I did Saturday, fairing away at the transom sides until they were finished. The starboard side had a bit more excess material than the port side. So, I roughed it in with the belt sander, then worked it the rest of the way down with the mouse sander. Unfortunately, I did not follow the “best practice” of checking my work frequently with my test piece of plywood. (I thought the transom sides would be a no-brainer. I was wrong.) When I tested my “finished” work with the plywood, expecting to feel a broad smile cross my face as I witnessed my handiwork, I was disappointed to see several gaps appear. The culprit was an overly sharp bevel in a couple of spots. More gaps to fill with thickened epoxy. I’m getting pretty good at that, if I do say so myself.

Needless to say,  I was more cautious with the port side. I also went about it a little differently. This time, I started by carrying the line of the sheer and chine through the transom material first. Then, I “connected” the two spots by fairing the area in-between. This time I alternated between the mouse sander and a small block plane. I worked slowly and purposefully.

The results were much, much better.

I do still have a good bit more fairing to do, primarily in the mid-section of the boat. I also have to make a decision about the chines in that area, (more on that later). I could’ve worked on all this Sunday. However, yours truly decided he needed some time on the water. So, I spent the day canoeing. I’m sure you understand.

By the way, I met another boatbuilder out on the river. He was piloting a very nice-looking red drift boat upriver. It looked about 16’ long. The handsome-looking boat glided smoothly through the water, pushed by a silent electric trolling motor. He proudly said “yes” when I asked if he’d built it himself. He had some very nice things to say about Don Hill’s drift boat plans before we each went our separate ways. 

Yep. You’ve gotta love the boatbuilding community.

Hot Springs Village Archaeological Site

Since we just got done looking at traditional Unangan beliefs I thought I would mention a website that features amulets from The Hot Springs Village archaeological site.   The site lets you rotate the pictures so you can view the amulets from all sides. If youre interested in carving your own, this is a great place to go for source material.
As the home page indicates, the source culture of the amulets is uncertain.  Apparently the place where they were found is right on the border of the Alutiiq and Unangan territories and so which culture made the amulets or whether more than one culture influence them is uncertain.  All the same, there they are, regardless of who made them.
