Tiernan adds that the reason most boats for sale today are made of fiberglass is that they can be made by semiskilled and unskilled workers who are cheaper to hire than the skilled craftspeople needed to build a wooden boat. Another is that when we build in wood or commission others to do so, we are helping to maintain an important tradition.
I wonder also whether the argument that building from wood is environmentally friendly has really been made. PS Fans of the US designer John Atkin will be interested to know that Tiernan is currently weblogging the build of a clinker-built Atkin Ninigret. PPS I’d draw your attention to some of the comments below, particularly those of West Country boat designer, occasional building and general sailing man John Hesp.
Gavin, most of Tiernan's list deals with the engineering advantages of wood, as if we bought boats based on these facts.
Trees have been growing, falling over, rotting, releasing CO2 into the atmosphere for years and it hasn't caused a massive increase in atmospheric CO2. I do see what you mean – it seems unreasonable to reduce these issues to numbers and engineering criteria when one of the key reasons we go boating is often to get away from such prosaic considerations.
Nevertheless, these issues are worth considering as I'm sure your inner designer will concede, and the environmental questions are much more subtle than most of us thought at the beginning.
And of course, carbon emissions are tightly connected to economic activity and human activity in general. On the other side of the issue, some fraction of whatever carbon there is in a plastic boat will remain locked in the material for a very long time. You don't think you've been led down the garden path by what sounds a rather journalistic BBC article? Ironing and washing, to be fair – both need more heat where cotton shirts are concerned.
One interesting little tidbit I read recently is that the meat industry in one way or another, contributes significantly more to global warming than transportation, worldwide.
One other nice thing about wooden boats, which has already been touched on a bit, but a nice one is gives pleasure to people, even when they aren't normally interested in boats. If the global warming cost of fossil fuels is added to that fuel we find ourselves playing a very different game.
Did you know that one barrel of oil contains the same amount of energy as 12 men working for one year?

Frosty Previous Member   Rowlocks for rowing boat Is there a position the oars should be on a rowing boat in terms of length from stern or the like etc? Most good boats have two oarlock positions and the seat has two or three mounting positions depending on the size of the oarsman, how many people are onboard and wind, sea direction. Upwind in a seaway I like to slide the seat forward and use the forward oarlock positiion .
If you are using wooden thole pin style oarlocks, its easy to have two or three oarlock positions.
I hav'nt got any rowlocks yet but will probably get the ubiquitous pin with a horse shoe type. It has a moulded in seat about 18inches from the transom so ile probably have to row in reverse unless I glass in a new seat which is not out of the question. Frosty Previous Member   Well If I have no seat yet or rowlocks where do I start .
Location: Washington When I was building my dinghy I was building from plans so I put the seat where they said, but if I had to do it over again I would lower the seat about 3 inches.
Step #1 draw a chaulk line on a leveled floor to represent the center of the boat stem to stern. Step #2 about half way along that line draw another line at 90deg to represent the beam of the boat.
Step #3 lay a 2x4 on edge along this beam line using it as a reference and fix the 2x4 so it remains on edge. Step #4 locate the center of the transom beam wise and draw a line down to it's bottm edge.
Step #5 place the boat on top of the 2x4 like a see saw alinging the bow and transom center line up with the stem to stern line in step #1. Step #6 balance the boat see saw style on the 2x4 on edge and you have located the approx center of boyancy. Step #7 on the exterior of the hull mark the location of the 2x4 where it exits from under the hull. Step #8 measure back between 12 to 13 in from the aft edge of this rowing seat on the gunnels and there is where i'd put my oar locks. Note, you might want to do a mock up on seat height, oarlock position, to fine tune to compensate for body trunk length, arm length, and the length of the oars you will be using.
Frosty Previous Member   Ok I put a piece of 1 inch PVC pie under the 1 inch keel. I could extend the seat a few inches forward and use that, it would mean that I could use the transom to brace my feet but the oar position looks very far back at 2 feet from the transom in a 8.9 footer. Originally Posted by viking north Ok, i'm a little confused, I thought the seat was fixed in place and we needed to locate the position of the oarlocks.

Location: Eastern NC Yep, you can't beat getting in the boat and trying them out before a permanent installation.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Location: Tasmania,Australia Self Righting Rowing Boat I think this story might be newsworthy enough for its own thread - thanks to Corly.

Location: Essex UK Out of interest years ago i built a Pete Culler Whitehall pulling boat. In the end we had to tie a 56ld weight to a bit of line on top of the mast to hold her down. A while ago I spent a season cruising in a very capable light dory I'd designed, the trips ranged from a week which took me from Dargaville down the Kaipara harbour to Helensville, to an afternoon trip up to Riverhead and back.
It's a lovely way to see the coastline, surprisingly fast in the right sort of boat and a lot easier than shouldering a pack through the bush, a doctor friend tells me that fixed seat rowing is one of the most beneficial and least destructive forms of exercise. I sold the dory to fund the next design and build project, but I missed the ability to be afloat within moments, and the glow of well being after a good hard row down the channel. Joansa, the name is derived from our family, is an adaptation of a late 1800's Chamberlain Dory skiff, native to the inshore fishing industry of the north east coast of North America. My modern day version is light enough to put on a roof rack, fast enough to win races and carries enough weight to take the three of us and gear on a weeks camping holiday. Joansa proved popular, she is a very pretty craft that attracts a lot of attention and plan sales have been so good that at least two boatbuilders took them on as a stock boat.
Our Joansa did a lot of miles for us, travelling quickly and easily – some of the mileage done under power with our 2hp Honda outboard but mostly under the oars she was designed for. Here at Gig Harbor Boat Works, we build ten different boat models from 8 to 17 feet in length. The Melonseed is a refined design from the sportsmans boat used on the bays of the Jersey Shore and the Chesapeake. The 16′ Swampscott Dory is an excellent open water and expedition classic small boat. The Lobster Boat is an excellent fishing boat, as a small motor will get you out to that hot spot fast, yet she rows easily for a slow troll.
The 14′ Whitehall is a classic small boat design suitable for rowing, sailing or low impact slide seat rowing exercise.
Just under 12 feet in length, Scamp boasts an unusual combination of features that give her the unique ability to explore waters too shallow for a larger boat, while retaining most of the bigger boat’s comforts and capabilities. The 12′ Point Defiance traces its heritage to the fleet of efficient, seaworthy small boats  from the early 1900s that were used for salmon fishing in the tide rips and chop at Point Defiance, Washington. A great knockabout small boat, suitable for cartop transport for boating on inland lakes and the inner harbor, and also makes an excellent yacht tender.
An ideal size for a yacht tender, it is small enough to sidemount on the yacht transom, and it tracks exceptionally well for towing. A lightweight 8’ boat that has good rowing qualities, sails like a champ, motors 8 knots with a 2 h.p.
And of course, please Contact Us with questions or if you need help finding the right boat. Boatbuilders teach each other, and the skills have long been conveyed by oral transmission. But if we only build boats out of oil, and keep a constant number of trees, there will be a nett increase in CO2.
I became aware of this when a BBC magazine looked at the issue and decided that the heat consumed in ironing a cotton shirt meant that poly-cotton shirts were a better environmental deal; so it seems to me that we should consider all the inputs and outputs, not just the obvious ones. Gaseous hydrocarbons are often very powerful greenhouse gases, and if a boat needs eight coats of varnish every two years, what's the impact of that? I wish someone would give me some nice, clear well worked answers that left me knowing where I was on all this, and that I could quote when the issue arises. I can guarantee that the energy expended per year ironing my cotton shirts is less than it takes to make a years worth of polyester shirts…. And it seems to me that I've never even owned an iron that got hot enough to iron a cotton shirt properly!
We should use wood because we want to, and save our agonizing about our carbon footprints for the times when it really counts.
I am not about to give up my roast lamb, but cutting my meat intake in half would do me good, and probably make a more significant dent in my carbon footprint than all the other little fiddles one reads about put together. The difference in the reaction of people when I am paddling some rental day-glo plastic fantastic canoe, and when they see me in my little varnished oak and pine S-O-F canoe is remarkable.
I seem to remember writing about the issue years ago, and finding that the energy savings from triple glazing can take a century to pay back the investment.
What's needed is some sort of mechanism where the cost of dealing with CO2 problems are paid for by the sources of CO2, then triple glazing and the like would look a lot more attractive finacially.
If person A manufactures a triple glazed panel using oil based energy sources the cost of energy is very low but the CO2 generated is very high. The cost of the triple glazed panel goes up slightly because of the embodied energy, but the cost of the energy being saved over, say, 20 years is a very worthwhile saving.

If you require further details regarding the transaction data, please contact the supplier directly. Transfer this to the inside of the boats sides and you have the approximation of the center of the width of the rowing seat. The effect of the passenger(s) on the trim also depends on the weight of the passenger(s) relative to the empty weight of the boat.

Worth, Tx, USA I don't think I would want to drag along that much of a boat.
Worth, Tx, USA Actually I couldn't get the link to work - it just sat there and churned.
I missed being able to take wife and daughter with thermos and picnic lunch exploring places as dissimilar as Westhaven Marina and the upper reaches of the Puhoi estuary. I fancied one of the classic round sided dories, the last one had been of the better known straight sided type adapted to plywood and to our our local conditions. This required a boat that was stable and fast, had a high carrying capacity, and was easy to handle even when short-handed.
Swampscott Dories were launched off the beaches of Massachusetts for fishing and lobstering, as well as used in the North Atlantic for fishing on the Grand Banks.
Our version of this classic small craft offers tremendous versatility; it can be rowed either tandem or solo, is a delight to sail, and can easily accept an outboard motor to make an excellent fishing boat.
With our busy working and family lives I have no hesitation in saying that we own and use at least one boat that we wouldn’t be able to keep up it on a DIY basis if it was made from wood. For example, when wood eventually rots its breakdown must release carbon dioxide and the much worse global warming gas methane. If the returns are so small, I'd suggest there are likely to be other areas we could cut down on that would make more of a difference. If person B manufactures the same panel using energy from photovoltaics the cost of energy is very high, but the CO2 released is very low. So here are the basic steps i used on the Shelbourne dory to locate the center one man rowing position. However I would make this the forward edge of the rowing seat to allow the boat to sit better on her floation lines. With this new boat I'd a mind to try for the efficiencies of the the more complex round bilge shape while trying to stay with the dories simple construction. They will help you decide whether or not you can build the boat but do not provide sufficient information to actually do so. Here is a photographic overview of all the boats we build, by size (from largest to smallest). The resulting design marries the best attributes of the classic Whitehall and New England Dory hulls. At the turn of the century, Whitehalls were a popular work and recreational boat in the harbor, carrying goods and people. So what is the lifetime cost of a wooden boat to the environment compared with a plastic one?
With regard to the maintenance I was referring to epoxy encapsulated wood like the Ninigret I'm building. The recession might have lowered energy costs, but I can see us coming out of it with soaring energy costs. It may or may not be the center of bouyancy with one or more passenters in the boat positioned so the boat floating with the desired trim. Sit up straight on the seat, have someone view how she sits on her lines and fine tune from there. With the Thole pins attached to the oars by a spliced lanyard (donut) the oars cannot be dropped overboard. While shooting the capsize shots, we found she had an interesting tendency to right herself even with the centreplate raised, the weight of the plate & buoyancy of the wooden spars was enough to set her rolling upright. Today’s adventuresome boater will find its carrying capacity suitable for long trips. Maybe plastic boat owners are more inclined to motor than sail, and maybe plastic boat owners are more attracted to resource hogging marinas?
Sure, we need a reasonably big car to haul the family around, but could we get away with an overgrown go-cart for the commute to work?

Just to add a factor that seems relevant, what is the contribution to global warming made by the drying of spirit-based paints and varnish? The idea with 1 rower is the center position with the seat approx CB location on her lines.

Your arm length does play a role here for comforth of rowing so a little trial and error is in order with some means of using a C clamp as the oar lock.
Also you can fine tune your boats trim with a rock or bag of sand.This dory design is a real rowing machine.
