More fairing on the Utility This time the transom

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.

Still fairing

The long, slow and laborious process of fairing continues. I was happy that over the weekend, I did make port and starboard contact at the bow. Although its hard to tell if its just the angle of the photo, it looks like I need to balance the symmetry of the joining sheer lines. I also have a small gap there on the front starboard side that I need to fill with epoxy.

The great news is, even though fairing is taking a long time, it is getting closer to being done.

Fairing day part 1

today, I sanded away all the high spots on the seams, and shaped the centerboard trunk slot using a router, and 7" disc grinder (aka wood eraser).  My arms are sore, but things are relatively fair.  I will need to order the fiberglass this week.   The plan is to use wide 6 oz cloth cut on a 45 degree bias, then apply 6 oz cloth over the whole hull.  This will be a long and tedious, messy task but will add value and years to the boat as well as much needed protection from rocky beaches.  I will put the keel on afterwards.





the PVC roller system is working very well to get this in and out.

The Utility Chines finished Fairing completed

I have finally gotten the 2nd set of additional chine strips shaped down to my liking. Im predicting that all of the faired surfaces will still have to be adjusted a little when the planking is being fitted. Thats fine. For the most part, however, I believe the fairing phase is basically done.

The first part of the planking stage will be to cover the transom with a layer of the Meranti Hydrotek. My goal is to bright-finish the transom, and I want it to match the deck. Before I can add another layer onto the transom, however, I have to sand down some remnants of dried epoxy.

Here are some iPhone photos of the progress:

I have to sand off these bits of dried epoxy before I can add another layer onto the transom.

Fairing the Utility

I have been slowly and cautiously fairing the Utility. I still have a long way to go, but I am making progress.

"Fairing," in case you didnt already know, is the process of beveling all of the parts of the sub-structure of the hull (frames, stem, chines, breasthook, transom, etc...), so that the plywood planking, when added, will have properly-angled surfaces to mate to.

For the newbie amateur builder (ie: Me), its probably the most daunting and intimidating step of building a boat. However, its a necessary and extremely important step.

I started by fairing the aft bottom section of the boat. Testing with a couple of plywood pieces shows that Ive got some slight gaps between the outer floor battens and the inner surface of the bottom planking. Im planning to fill these gaps with thickened epoxy when I attach the planking.

Ive done preliminary fairing on the bottom of the chines up to the forward frame.

Over the last several weeks, (since adding the chine strips described in my last post), I have been fairing the forward bottom section. Most of this work has been on the starboard side. Ive been using the Rabl method for fairing this area. The Rabl method was developed by Sam Rabl, and is described in detail on the Glen-L website here: http://boatbuilders.glen-l.com/3820/fairing-by-the-rabl-method-2/

For me it is slow work. Ive been using a couple of sizes of hand planes and a belt sander, and checking progress frequently with straight edges and my plywood test pieces. My recommendation to the new builder beginning the fairing process would be to simply take your time. Proceed slowly, check your work frequently, and expect this stage to take a long time. Its easy to try to hurry the work along, then inadvertently create gaps or gouges that youll have to fix. (Trust me.)

Ive still got a long way to go, but I will share some photos of the progress so far.

More fairing work has been done on the starboard sheer than on the port side so far.

Fairing and keel

August 15th, 2014

I am finally closing in on the final stages of hull finish prep.  The third coat of epoxy just about filled the weave, and then the boat gets a quick sanding (three hours) to remove the globs, and just a fraction of the remaining bumps from the glass.  Next,  a fill with fairing compound, hand sand with the long board, then fill and fair until I get sick of it.  The keel will be installed afterwards as well as the centerboard gasket, then primer on the hull prior to turning.  The goal is to get the boat back upright and the majority of the interior finished prior to the weather window closing in at the end of October.

6 oz glass set in 3 coats of epoxy that have been squeegeed on.

got the first coat of fairing compound (WEST 407) on it today.  It takes about three hours to apply a thin coat all around.  Shame is, I gotta sand most of it off to find the low spots.  Sundays project.  Hopefully painting by Labor Day.

August 26, 2014
8 hours of sanding later...I would highly recommend a thicker coating of fairing compound.  Too late now.  Just order more microballoon filler.  Arms hurt, ears, hurt, much sandpaper, Sanding sucks.  Oh...the bottom is ready for primer and the keel.

Sides tomorrow.
