Kelly wants to build a faering

I need more tension on the luff, but it was my second sail.
Kelly, from Kerrville, Texas, is thinking about building a faering to sail and row primarily in a wide, deadwater river area with submerged cypress stumps. He wrote me with a couple of questions.

"I believe the length of Atkin's plan is preferable to 16'6'' in Oughtred's Elfyn design. However, Atkin's plan is described as finishing at 600 lbs.  Understanding that includes lead ballast, more meat in the keel, and so on, I'm concerned about draft.  Oughtred's plan says it finishes around 150 lbs."
A friend of mine, John Kohnen, told me Atkin said in one article the boat would weigh 600 pounds. In another he said it should weigh 450. I need to find a truck scale near a place with a boat ramp so I can weigh mine. My guess is that it would be closer to 450. Although I'm a belt and suspenders kind of builder who tends to overbuild things, I tried to rein myself in during Ravn's construction.

The design calls for 106 pounds of lead in the keel and I put in 98 pounds, according to my bathroom scale. I used purple heart wood for the keel, which is pretty heavy and with my tendency to overbuild, I thought I'd knock off a few pounds so I wouldn't come in too heavy. As far as I can tell, she floats right on her lines, so I think I succeeded.

I would not leave out the lead. The lines of the Valgerda are, according to Atkin, taken right off a Hardanger Fjord faering. Traditional boats built with modern methods (stitch and glue or glued lapstrake) usually end up lighter than the original. I think this would be true of Valgerda. If she didn't have the additional lead in the keel, you would have to add ballast inside to bring her down to her lines. I don't like the idea of lead pigs (or rocks) sliding around in the bilge. Were I to have inside ballast, I think I'd use sand bags, but that would be a hassle too.

I made the keel six inches shallower than on the plan making the draft about 12 inches instead of 18. I also gave her a little more skeg than Atkin drew. My reasons for these changes were these: I wanted shallower draft to make her easier to get on and off a trailer and because my primary cruising grounds include the beautiful coastal rivers of Oregon. The shallow bars require a shallow draft and good directional stability when you are on top of a wave (hence the increased skeg area). Beaching is easier too with less keel. Another possible advantage is a little less wetted surface, which would make her easier to row and may provide a little advantage in light air.

The only down side to the changes is that the deeper keel that Atkin drew should - theoretically - go to windward better. If you want a boat that you can tack upwind in a narrow channel, Valgerda is not your girl, even with the deeper keel configuration. In that situation, I drop the sail and row. That said, I am happy with my boat's windward performance: she is close winded, won't stall in a tack if you have enough way on and the right tension on the luff rope, and if she makes any leeway it's too little to notice.

An East Coast builder, Rick Nardone, built a Valgerda about the same time I built Ravn. He eliminated Atkin's fin keel too, opting to return to the more traditional faering keel, which is about four inches deep. His boat draws about 10 inches. Rick's been a real busy guy and I've only received one rowing report from him, so I don't know how she sails. That's another approach you might consider. (I think his boat may be for sale, by the way, if you want to skip the hassle of building a boat.)

I agree with you that Oughtred's faerings seem short. Modern Norwegian faerings are 18 or 19 feet long and the older ones, like the one buried with the Osberg ship, were more like 22 feet. Oughtred's  
Arctic Tern and Ness Yawl designs are the length I would consider, but there's something I really like about the three-strake faerings.

If, however, you decide you want something lighter or with a centerboard, by all means go with an Oughtred design. They are beautiful boats and, by all accounts, stellar performers. DO NOT put a centerboard in the Valgerda. I think that would really mess the boat up for little gain and a lot of unnecessary complication.
"Also, I'm curious as to whether or not you considered building in solid wood. After pursuing many boatbuilding sites now, I nearly have the impression that building a traditional craft in traditional style is less work than modern plywood and epoxy.  Not that simple, I'm sure."
By no means is building in solid timber easier. It takes more esoteric skill, is less forgiving and materials are harder to come by. (To build Valgerda, for instance, you would need board 22-inches wide and about 20 feet long for the mid-plank. Good luck finding that!) Then, once you have her built, the fun really begins. A traditionally-built faering needs to spend its life in the water or out of the sun and dry wind in a boat shed. Keeping a traditionally-built faering on a trailer - especially in a dry, hot place - would simply kill it.

Adrian Morgan, a boatbuilder in Scottland, built an all-wood version of one of Oughtred's faerings. Check out his blog and web site.
  
Now, about Kelly's shallow lake with sumps: I built my boat with just such conditions in mind. Where I sail there are lots of rocks just under the surface and plenty of deadheads too. I haven't had any collisions yet, but I put a double layer of 6-ounce fiberglass cloth below the waterline and built my keel and stems extra tough out of purple heart. I'm confident she could take a pretty good hit.
I don't think Kelly could go wrong with Valgerda or an Oughtred design. I told him another design he might consider is the Sellway-Fisher Kari 2.

The important thing is to build one. I hope I can post photos of his progress here soon. The world needs more faerings!

  1. Brandon,

    It's nice to see that one of us gets to use his Valgerda. Ravn is GORGEOUS.

    As you say, I have been extremely busy - new job, a wreck of an antique house, and all of the regular day-to-day stuff has kept me from making any progress on Dark Secret's rig. Hoping to have her wrapped up for this spring, but...

    I'll post again soon.

    Rick
