Cope Aluminum Boat Designs A large number of aluminum single hull (monohull) boat designs (plans) that serve a variety of purposes. These include Orcas, Outbacks, Sitkas, Sportsters, Sport Fishers, Crew Boats, Crab Boats, Dive Boats, and Patrol Boats. Incredible Boats From Great Designs. To build a great boat you have to have a great design. Our naval architect uses a semi-monocoque design that takes advantage of the aluminum's plate strength. You may be familiar with this design type in the carbon fiber car bodies of both Indy and Formula 1 cars where there is Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen no true frame the skin is. All designs for aluminum construction are included here. For further study, we have books available in the Books, DVD's and Audio section of our store at your left.

Every material used on our boats is meticuously researched and tested for strength and durability. Click each heading for more info. Every step of Aluminum Boat Design Plans Queen our building process is precise, controlled, and quality checked along the way. Pacific Boats has built earth friendly products since A Pacific boat's Aluminum Boat Design Plans Queen light weight makes it more fuel efficient than a comparable length fiberglass boat. Have you ever asked yourself "where do all the old Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen fiberglass boats go?

Fiberglass does not break down. Over the years, this has become an environmental issue. Home Recreational Commercial About Contact. Pacific Skiffs, Inc. Marine Grade Alloys. We use only the finest materials available. The series of marine-grade alloys are specifically made for full-time saltwater applications. This Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Queen Design Plans material is applied to the self bailing deck and consists of a phenolic, alkyd rust-inhibiting etching primer base and alkyd enamel topcoat surrounding an Aluminum Boat Design Plans Queen aggressive non-skid abrasive.

Not for the faint of heart, nor the bare of foot, this material is similar to the new bed-liner material you may be familiar with as an aftermarket application in pick-up trucks. It gives you tough, durable, surefootedness in all weather conditions. Along the length Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen of the chine is an extrusion that both the side and the bottom plates fit into. This high impact area is then double Aluminum Boat Design Plans Queen welded on the inside the entire length of the boat.

This level of quality is unheard of even in custom alloy boats. Router Cut. In Aluminum Boat Design Plans Queen fact, there can be many suitable approaches and variations. Second, there is no reason why you can't build your own aluminum boat Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen in your own garage or backyard that looks identical to one produced in a factory, and with similar weight and strength qualities even if Aluminum Boat Design Plans Queen you don't use the same mass production methods, or have access to sophisticated, specialized equipment and proprietary materials.

Consider the following. Because production builders are always thinking up ways to cut labor and material costs, and time required to build boats, they evolve specialized methods and materials Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen that help toward these ends even if there is not necessarily any improvement in the boat itself. For example, they may use special proprietary Aluminum Boat Design Plans Queen extrusions to expedite some assembly process such as joining side and bottom plating at the chine see Fig.

But when building your own boat, you may not have access to such a specialized member, nor could afford it or the shipping in the small quantities you'll Aluminum Boat Design Plans Queen need even if available.

Alternately, your chines might then be backed with a simple round bar Fig. None of these methods is necessarily superior, but just different due to circumstances.

Also, production builders often make up sophisticated re-usable production jigs over which pre-cut hull panels are assembled and welded first. These jigs may also rotate to facilitate high-speed welding, with internal members added after the hull is removed from the jig. But Aluminum Boat Design Plans Queen when building your own boat at home, it's just as likely that the boat's internal framework gets built and set up first, Aluminum Boat Design Plans Queen with plates fitted over this, marked to shape, cut to suit, and then welded in place after.

In Jet Boat Design Plans Queensland other words, the boat's Aluminum Boat Design Plans Queen framework becomes the forming jig and stays in the boat; you make it and pay for it only once. In either case, end results are much the same and with comparable boat quality. Using a frame substructure for setting 20 Foot Aluminum Boat Plans For Sale up your hull has several advantages for the do-it-yourselfer Aluminum Boat Design Plans Queen typically working alone. First the frame substructure makes it easy to assure hull accuracy that is so important to ultimate performance in a powerboat.

Second, the framework makes it possible to build from "off-the-shelf" materials and shapes available anywhere for lower costs and easier material purchasing. Finally, the Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen framework makes it easier to form hull members in place and during weld-up since clamps and other devices can be readily used most anywhere Aluminum Boat Design Plans Queen as required, acting as extra pairs of "helping hands" in the process. Factory production boatbuilders often use specialized forming equipment not always available Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen to amateurs, or use forming services that might be provided by metal suppliers when quantity requirements are high.

Conversely, a design for the do-it-yourself builder would more likely specify internal longitudinal stiffeners i.

Either method gets the job done but the latter is easier and cheaper for most building their own boats. First, a disclaimer. But in reality few do-it-yourselfers want to pay the price for the service. But steel is considerably heavier than aluminum, so boats designed for steel are usually designed for greater displacement.

Thus, if the boat is built from aluminum, it won't be nearly as heavy and may therefore float higher in the water. The consequences for a semi- or full-planing powerboat might be so Aluminum Boat Design Plans Queen Design Aluminum Queen Plans Boat much the better since the lighter aluminum boat will need less power and fuel.

But in converting slower displacement-type powerboats from steel to aluminum, you might need to add ballast into such a boat done in aluminum to bring it back down to its original lines. This Aluminum Boat Design Plans Queen may place the center of gravity too far below that of its steel brethren and result a snappy, jerky motion.

So instead, you may Plans Boat Design Queen Aluminum Aluminum Boat Design Plans Queen want to place some of the added weight higher up. But again, best advice is to consult the boat's designer. Aluminum is not Aluminum Boat Design Plans Queen as strong as steel so some compensations must be made if using it in place of steel. Without getting too technical, with aluminum used Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen for shell plating e.

Put another way, to get the same strength as steel in an aluminum hull, it needs to be approximately half the weight of steel. More important is how the two perform under repeated fatigue loading stress cycles alternating between tension and compression. Tests show Aluminum Boat Design Plans Queen that for a similar number of cycles, steel stays above its yield strength threshold. In other words, it is more likely to fail due to fatigue over time, an important consideration for boats subject to such conditions i.

The point is that if you decide to adapt Aluminum Design Queen Plans Boat a steel design to aluminum, you'll need to increase scantlings i. But by how much? Converting from steel to aluminum is fairly straight-forward mainly because the members used are much the same in configuration and the methods of design and construction are similar. And while there are Aluminum Boat Design Plans Queen standards-making organizations e.

After all, we're talking relatively small boats here, and as we'll see, the sizes, types, and thicknesses of members Aluminum Boat Design Plans Queen readily available and suitable put some practical limits on what can be used to frame up and plate a metal boat in the first place. Consider plating thickness. On the steel boat, this is more often based on the practical minimum necessary to ward off corrosion over Aluminum Boat Design Plans Queen time, provide decent welds, and a thickness adequate to minimize unsightly deformation.

Thus 10GA. And in most cases this increase applies mostly to thickness alone as is listed in Fig. An operating premise is that steel boats in the size range discussed are almost always stronger than is Aluminum Boat Design Plans Queen necessary; this due to the nature of the material, for reasons previously noted, and the fact that the shape of most boats adds strength Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen in and of itself, and often where it does the most good such as in the bow.

Thus there is some latitude in the conversion process - we're not talking rocket science here. So using the example, 10GA. In other words, multiply the thickness of the steel Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen member by a factor of from 1.

Tip: Start with 1. That's basically all there is to it. In the above and referring to Fig. These members are common in steel boats rather than using formed or extruded members such as angles, channels, tee's, etc.Aluminum Boat Design Plans Queen

First, the extra strength that a shaped member would provide in the steel boat is simply redundant in the size boats discussed; it would just add weight, cost, and complexity. Second, shaped members add to the difficulties of inspection, maintenance, and corrosion protection in the steel boat; for example, the ability to see and coat the underside flanges is difficult, especially when such members are small. However, in the aluminum boat in Fig.

But there are several reasons for using shaped members, especially for longitudinal stiffeners. First, such members are stronger. Or put another way, you Aluminum Boat Design Plans Queen could have the same strength in a lower-profiled shape than with flat bar. And the added strength in the aluminum boat is a Aluminum Boat Design Plans Queen plus. Another benefit might be more usable interior volume. And because marine aluminum requires no corrosion resistant coating and won't rust, the shaped members don't add to maintenance and inspection difficulties as in the steel boat.

Finally, shaped members, especially those of symmetrical section such as Aluminum Boat Design Plans Queen tee's and channels, are easier to work. They tend not to be so floppy, and bend more uniformly than flat bar. The downside is that extrusions cost more than flat bar or the sheet stock one can use to make flat bars, and may not be readily Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen available at least in the size you want. If working from stock plans for an aluminum boat, the designer probably specified certain sizes, types, and alloys of members for framing, etc.

But deviations may be possible. Most designs have some latitude in alternates that can be substituted. For example, angles can be substituted for tee's and vice versa. Channels can be made from split square or rectangular tubing, or even Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen split pipe if somewhat larger than the specified channel. You could even fabricate Aluminum Boat Trailer Kits For Sale Queen your own sectional shapes from built-up flat bar. Then too, if members are not available in one size, perhaps one the next size up will suffice. However, you should always consider the consequences of added Aluminum Boat Design Plans Queen Aluminum Boat Design Plans Queen weight that such a change might make.

Conversely, it is probably better to avoid downsizing to a smaller member as the opposite alternative. To Aluminum Boat Design Plans Queen the novice, there is a bewildering array of aluminum alloys available.

But for the welded aluminum boat, the choices narrow down to the so-called Boat Design Queen Plans Aluminum marine alloys in the and series, the latter typically being extrusions.

Yet even within these series there are still many alternatives. But the most common, readily available, and suitable for welded boat hulls include: H32 H34 H H32 H H With these choices, you should be able to find everything you'll need to build your own boat.

However, the designer may have already taken this into consideration if is specified. Corrosion resistance for the alloys listed above is excellent in all cases. The material has good corrosion resistance also and is commonly used for Design Plans Queen Boat Aluminum extruded shapes. Many have substitution guides you can use to suit what's stocked.

Early aluminum boats were often made with closely-spaced transverse frames with few, if any, longitudinals, a carry-over from traditional wood boatbuilding no doubt. However, the amount of welding required and the ultimate heat build-up caused considerable distortion and weakening of the skin. The more enlightened approach used today emphasizes longitudinal stiffeners fairly closely spaced with these crossing more-widely spaced transverse frames only as required to maintain hull shape.

In fact, some smaller welded aluminum boats may need few if any frames Aluminum Boat Design Plans Queen at all, especially where bulkheads may serve double duty. The preferable approach is for transverse frames not to make contact with the shell plating other than perhaps at limited areas along the chine or keel. In effect, such frames are "floating" within the hull, and are used to support and reduce the span of longitudinals which are the primary members stiffening the hull plating.

About the only case where a transverse bulkhead Boat Design Plans Aluminum Queen needs to make continuous plating contact is if it is intended to be watertight. Even then, such a practice tends to distort the plating Aluminum Boat Design Plans Queen and is often readily visible on the outside of the boat. In short, general practice is to NOT weld plating to transverse frames or Aluminum Boat Design Plans Queen bulkheads even if such members touch or come near the plating. The chine is the junction between the bottom and side on a v-bottom or flat bottom boat.

On high-speed planing boats, this corner should be as crisp are possible, especially in the aft half of the Aluminum Boat Design Plans Queen hull. The reason is that water should break free from the hull to reduce frictional drag at speed, and not climb up the topsides. As Aluminum Boat Design Plans Queen shown before, Fig. Backing members such as in 'C' and 'D' help tie frame members together when setting up and help define the chine line to assure a smooth, fair curve. Otherwise, a backing member is largely optional. If a special extrusion as discussed before is available, Aluminum Boat Design Plans Queen these are acceptable.

The example in 'E' includes a built-in spray deflector, and can be bent along its length as required to conform to Aluminum Boat Design Plans Queen an ever-changing angle between the side and bottom that commonly occurs. Side and bottom plating fit into the slots which are then welded continuously.
