JOHN C. Contemporary plywood hulls can be elegant and refined. In order to attain the level of form and finish seen here, a marine wood for boats 7000 must be careful in choosing stock.

A great deal has changed in the world of plywood since those masters of the medium made the recommendations quoted. The prospective plywood boatbuilder of wades into a thicket of unenforced standards, uneven quality, and outright flim-flammery. I started building boats in the s. The exterior-grade AC fir plywood that Dynamite Payson advocated was already in precipitous decline. Even if you could find a panel not riddled with core voids, it marine wood for boats 7000 be warped like a potato chip.

Modestly good underlayment-grade lauan plywood could still be had, but the paper-thin face veneers and crumbly core that distinguishes lauan today would be the norm by the wodo s. Okoume was the stock in trade when I joined the nascent Chesapeake Light Craft in Strong for its weight and with a pleasing honey-colored grain figure, okoume is a marine wood for boats 7000 choice for lightweight stitch-and-glue boats.

This veneer is sprayed with glue and stacked to form a panel, with each layer laid with the grain oriented 90 degrees to the previous one. Plywood quality varies depending upon its wold use, and builders should be well acquainted with grading standards.

Wood all marine plywood is made by peeling a giant continuous sheet of veneer off a spinning log, like tissue paper off a roll. Plywood made of such veneers is known as rotary-cut plywood.

Sliced and ribbon-stripe panels are common in marine grades, but are used mainly for decorative joinery. Rotary-cut veneers are dried with great care to a moisture content of less than 8 percent. While much of the marine plywood used today originates in the forests of equatorial Africa, all of the veneer is dried elsewhere, mostly at mills around the perimeter of the Mediterranean. Equatorial Africa is damp, and plywood made there would warp the moment it arrived in a less humid climate.

The veneers are sprayed with glue, stacked up with the grain of each layer at 90 degrees to the next, then squashed in a heated press for a few minutes. Thicker plywood takes longer to cure. It has to do with managing moisture content, veneer orientation, and veneer thickness.

Plywood in which veneer species are mixed, or in which face veneers are too thin compared to the cores, are especially susceptible to warping. At the end of the production line, the plywood is trimmed and stacked for shipping. Veneer quality is the primary difference between marine plywood and the stuff at the home center. The best imported marine panels will have face veneers without blemishes, patches, or seams in the veneer.

Average and better marine plywood will be free of marine wood for boats 7000 voids. Watch out for overlaps of the core veneers, which create weak spots and cause an ugly crease in the surface veneer.

Glue for marine plywood is a settled science. It will be either phenolic resin or melamine. In marine wood for boats 7000 experience both are equally durable. The phenolic glue is black and will show up more readily if you sand into it. The melamine glue is somewhere between clear and milky-white, and some builders prefer this for panels in which sanding might reveal the glue lines. To qualify as marine plywood, a panel must have no voids.

It must also be assembled using marine wood for boats 7000 durable glue, and must pass rigorous testing for longevity. A few suppliers will make up long panels to order, sparing you the trouble of sharpening your plane and cutting scarf joints. Ask to see marinee sample of a scarf joint before emptying your wallet.

The APA started life as the Douglas Fir Plywood Association, a name that stirs nostalgia as a source for funky boat plans in the old days. Like most, this is a voluntary standard, though in my experience marine wood for boats 7000 domestic marine fir is uniformly high quality.

BS is the coin of the realm, the sine qua non of plywood grades. The important thing to understand is that it is a voluntary standard. British Standards are issued by the BSI Group, which operates under a Marine wood for boats 7000 charter and administers national marine wood for boats 7000 for British manufacturers.

The U. Almost any one of those features would disqualify plywood from use in my shop, and it illustrates the variability of quality permitted under the standard. A lamentable amount of plywood no better than home center underlayment is advertised as BSwith unflinching villains ready to sell the stuff to bargain-hunting boatbuilders.

Now officially retired, BS persists as a recognized standard for slightly lesser plywood. For those keeping track, the new equivalent is BS EN Purchased from the better mills, BS plywood is usually just as pretty as BS Any charlatan can slap flimsy okoume face veneers onto Chinese poplar, have a stamp made, and call it BS So how do you find the good imported stuff?

Research the reputation of the plywood mill and marine wood for boats 7000 supplier before you buy. The companies that have been around a long time have a track record of consistent quality.

Douglas-fir marine plywood is strong and rot resistant, but due to its unstable grain is a poor choice for fine finishing unless sheathed in fiberglass. As of this writing it remains marine wood for boats 7000 only widely available domestically grown marine-grade plywood. All veneers are Douglas-fir or western larch.

While this was once open to some debate, in it almost goes without saying that marine fir plywood should be sealed in fiberglass or epoxy or. The face veneers feature abrupt transitions between marine wood for boats 7000 and soft grain, which makes a smooth surface difficult to achieve without a stabilizing coating of epoxy. Stick with the A-A variety, which means both face veneers are reasonably clear.

And count on fiberglassing and painting the plywood. Meranti plywood is a good, economical choice. It is heavier and stiffer than its closest competitor, okoume. It was developed as a weatherproof material for the manufacture of highway signs, and it tor indeed take paint well and is durable.

The paper coating gives the normally rough fir face veneers a smooth, hard, paint-ready surface. Epoxy and fiberglass stick to the phenolic coating just fine.

Meranti belongs to the family Dipterocarpaceaelowland rainforest trees markne are native to Southeast Asia. Excessive marin illegal logging and the fact that some Dipterocarpaceae species are endangered has led big-box stores such as Home Depot and Lowes to limit its use in the United States.

Relatively inexpensive in marine-grade spec, meranti appeals to amateur boatbuilders. Most meranti is a better fit with the BS stamp. Thicker panels 9mm and up have a more marine wood for boats 7000 quality, perhaps because the economics of thicker panels work better for the plywood mills. A thick panel and a thin panel both eat up the same two valuable face veneers, but the mill can charge a lot more marine wood for boats 7000 the thick panel.

Meranti is denser and some 10 percent heavier than its competitor, okoume, and a little stronger. It has a dark color sometimes resembling walnut.

Okoume is 70000 most common choice for small-boat construction: it is soft, flexible, and light. Aucoumea klaineana is an African hardwood found in the Congo Basin. Okoume is now so ubiquitous in small-boat construction that it scarcely needs introduction.

The color ranges owod blond to reddish-brown, sometimes within marine wood for boats 7000 width of a single face veneer. A cubic foot weighs just over 25 lbs. As the wlod popular of the tropical imports, okoume is available in a large variety of thicknesses, from 1.

Marine wood for boats 7000 water will turn okoume into mulch, and soon. Designers always specify marrine epoxy or fiberglass coating. Okoume and epoxy belong together like beer and pretzels. Using okoume as a core material in epoxy-composite assemblies results in wondrous feats of engineering: dinghies that weigh 80 lbs, kayaks that weigh 40 lbs, canoes that weigh 30 lbs.

Okoume is the easiest to bend of the popular marine plywoods. Boats designed woos it, especially of the stitch-and-glue variety, might be difficult to assemble if bowts stiffer material such as fir or meranti were substituted. Consult the designer before swapping species. Sapele is a tall deciduous tree, a relative of African mahogany.

Most of the sapele that finds its way to the United States is harvested boags Cameroon. The veneer has a lovely fudge-ripple-swirl figure that most find irresistible under varnish. The glued-lapstrake plywood boats of Iain Oughtred or John Brooks, for example, are an excellent fit for sapele. Like okoume, sapele is made into plywood at mills all over the world, and panel quality ranges from calamitous to surpassing.

Vendia, a plywood made of Mariine pine, is the newest thing on the plywood market. It is strong and stable, like all plywood, but because it's made from sliced rather than peeled veneer it resembles solid wood. The pulling boat below is made of it. Not all marine plywood marjne imported from Africa and Southeast Asia.

One example is Vendia of Finland, who offer an unusual sliced veneer plywood made of slow-growing Finnish pine see review, WB No. The result has the strength and stability of plywood but looks a lot more like solid timber. Glued-lapstrake boats built of Vendia Marine Plank are strikingly handsome with a clear finish.

Nevertheless, Vendia Marine Plank may point the way to the future of boatbuilding plywood: local species sliced into high-quality panels in small, artisanal batches.

Before you visit the lumberyard or wood shop, decide whether you need a light wood such as for spars, oars and dinghy parts , or a dense, heavy wood for hardware mountings and other fittings.

Iroko and Rhodesian teak � not a true teak but a much tougher wood � are two common teak substitutes. Similarly, spruce, pine, and fir are frequently graded as equivalent in the Marine Wood For Boats Designer Pacific Northwest: the letters SPF are stamped on lumber to assign this aggregate designation.

Moreover, within each wood species there is a great variety in color and grain. Odd as it may sound, put your nose to the wood and smell it. Take a deep whiff and try to remember the scent; this is sometimes the best guide in matching wood species. Ask around at marinas or visit wood shows and specialty stores.

Hardware megastores usually carry only a few wood species such as oak and pine and fir, and much of the wood is damp. Instead, look for a supplier who deals in kiln-dried hardwood and woodworking tools.

These outfits are typically well-staffed and well-stocked. The science of wood decay is inordinately complex, but much of it comes down to a single factor: moisture content. Ask the shop staff about their policy. Many wood suppliers have stacks of wood outside. No matter how enticing these look, avoid them. Wood stored outside is wet, and finding dry wood is your most pressing concern. Wet wood is difficult to work, is prone to decay, and will shrink over time.

Find wood that is stored in a heated, insulated building. Naturally, the best boards are always at the back or bottom of the stack. Check the moisture content. If the wood feels or smells damp, move on.

Dry wood tends to be rough and splintery on the surface, whereas wet wood fibers feel smooth to the touch. In place of a moisture meter, this shorthand might help, but be aware that wood dries from the outside in, and dryness on the exterior by no means guarantees dryness throughout.
