Crafted in mahogany and tropical hard woods, the hulls are assembled one at a time, using traditional plank-on-bulkhead modelling techniques. After the bulkheads are laid and the hull lines trued, the hulls are planked with individual wooden stripes to form a smooth silhouette. The model is then hlul, hand painted and varnished to a mirror-like finish. They are then mounted on ready to hang wooden plaque, each is complete with an engraved brass nameplate.

Gordon Kerr, Duffy Down Under chief executive. They work harmoniously in the Gold Coast Marine Park with its varied fish life, dolphins, turtles and whales. As an added bonus, the electric boat motor is allowed in the Gold Coast areas where petrol-powered boats are forbidden. I firmly believe Duffy Electric Boats and the new Duffy 22 model will be ideal for those waterways,' noted Marshall 'Duffy' Duffield, company founder. About Duffy Down Under Pty Ltd Duffy Down Under is introducing Duffy Electric Boats to the Queensland marketplace by raising the profile and awareness of these unique outboards electric motors , which are available for sale and also for hire seven days a week weather permitting.

The company also offers catering in partnership with local restaurants as well as group events and theme events. More at duffydownunder. The company currently produces over eight different electric boat motors models.

Each Duffy model is constructed from the highest quality materials in a company-owned factory located on over six acres in Adelanto, California.

Duffy electric boat motor are emissions-free and low-maintenance. Up to the present time the electric boat motor owner has only had available one type of battery chemistry to provide propulsive power for their electric boat motor no matter whether the electric boat is an inboard or outboard motor. This battery type is of course the lead acid battery. There are two main variations to the lead acid battery depending upon its specific application.

Broadly speaking the lead acid engine start or "cranking battery" in its intended application is designed to provide a short, high power burst of electrical current to crank over either a petrol or diesel engine while starting.

This is the type of battery which commonly provides house power on boats as well as presently being the most common type to power electric boat motors. Both types of lead acid batteries however have severe limitations.

In addition lead acid batteries contain nasty chemicals such as sulphuric acid and toxic heavy metals like lead which are potentially hazardous to the environment. Lead is a very heavy metal and for many years the search has been on to make a better battery that is also lighter in weight. Lithium is the logical choice since it is the lightest metal known to man. However in addition to being extremely light in weight, lithium is also extremely reactive and for this reason pure lithium metal is never found in nature.

Lithium metal is manufactured from lithium salts which are extracted through mining activities mainly from brine lakes. It can also be extracted from sea water. Lithium ion batteries have been available for several years for many consumer applications which most people would be familiar with. As with lead acid batteries, lithium ion batteries also are available in several chemistries, each having their particular good and bad points.

The earliest lithium battery chemistries which became a commercial reality and which are still in use today for consumer items like mobile Lithium Iron Phosphate LiFePO4. Li-Co batteries have high energy densities but have the disadvantage that in large format applications and in cases where many separate cells are used which can potentially become unbalanced during several charge cycles, they can pose a dangerous risk of fire or explosion is a possibility.

While these batteries are generally considered quite safe in small format applications such as for mobile phones and the like generally one cell only is used therefore this is why the battery voltage of a typical mobile phone battery is 3. Unlike the hazardous nature of the earlier chemistry lithium battery types, lithium iron phosphate batteries are extremely stable and safe to use.

This safety combined with their light weight has found wide use for these batteries for military applications and now for the emerging electric vehicle markets including electric boats.

They are in fact even safer than lead acid batteries and do not suffer from some of the problems which are inherent to lead acid batteries such as, thermal runaway, sulphation when left in a discharged condition and high rates of self discharge if not used.

Lead acid batteries generally have a life of only a few hundred deep charge cycles while a quality LiFePO4 battery can typically be charged in excess of times. Though not as high in energy density as the earlier lithium battery types, the lithium iron phosphate battery still has a far higher energy density compared to the lead acid battery as can be seen from the graph on the left.

In recent years large format LiFePO4 batteries have been made to replace lead acid batteries and these batteries are now being widely used for battery packs to power electric vehicles as well as hybrid electric cars. They are also being used in high power electric cordless power tools.

The benefits to the boat owner of a quality LiFePO4 battery are many. Normally the electric motor requires a voltage of 36V, 48V or higher voltage while 12V is required for house power, radios, Lithium battery bank navigation lights, etc. It is very bad practice and still used by some manufacturers to simply tap off 12V from a single battery in the main battery pack to supply this lower voltage.

This can lead to uneven discharging of different batteries due to varying loads which can further result in some batteries being over charged while others end up being less than fully charged.

Another major factor which should be taken into consideration when replacing a lead acid battery with a LiFePO4 battery is that due to the higher energy density and greater performance of the lithium battery often a smaller battery can be used which will provide equivalent or better performance compared to the original lead acid battery. This difference in performance can clearly be seen if both battery types are compared side by side in high current drain applications for example if used to power an electric boat motor at high power settings.

What many people fail to realise about a lead acid battery is that its capacity Ah rating is usually specified at the 20 hour discharge rate. At high rates of discharge the effective or "real" battery capacity is reduced considerably due to "Peukert's Effect". A typical Ah lead acid battery when discharged in an hour or two may have an actual measured capacity of as little as Ah. LiFePO4 batteries are not negatively affected in the same way by Peukert's Effect as are lead acid batteries.

When a lead acid battery is connected to a load such as an electric motor for example the voltage slowly continues to decrease until the battery is completely discharged. By contrast the discharge characteristic of a LiFePO4 battery is quite different.

Therefore a LiFePO4 battery can be almost fully discharged yet it will provide very close to the same power as when it was fully charged. Another great benefit of Lithium Iron Phosphate batteries for boating applications is due to their inherent safety features. Since they do not produce flammable hydrogen gas under any circumstances even if overcharged a LiFePO4 battery can be safely installed in a confined place in a boat or ship without fear of a fire or explosion occurring.

There is absolutely no maintenance required so a battery can be fitted into an out of the way space in an electric boat such as under seats, under stair wells, in the hull, etc. Due to slim cylindrical nature of many LiFePO4 cells a custom battery of virtually any shape can be made which will fit into any tight space in an electric boat. Battery cells can even be fitted inside a mast or inside hollow railings.

Another advantage of LiFePO4 batteries is their rapid charge capability. High quality batteries can be re-charged extremely quickly. For many electric boats this rapid charge capability will be a godsend. Weight is another factor of concern to owners of electric boat motors. A Lithium Iron Phosphate battery is usually about half the weight of an equivalent capacity lead acid battery. For example the photo of the battery bank below shows a large LiFePO4 battery bank used to power three motors fitted to a 55ft electric racing catamaran.

It was originally planned to fit more than half a ton of AGM lead acid batteries to this boat before the owner learned of the benefits of LiFePO4 batteries. Due to the many benefits the owner of the boat decided to install LiFePO4 batteries instead and was able to reduce the total weight of the battery bank by more than half with the total of all twelve batteries weighing in at less than kg. To sum up, an overview of the benefits of Lithium Iron Phosphate batteries:.

C or more without any degradation in performance. There are already several brands of LiFePO4 batteries which are available to boat owners and are suitable for powering many kinds of electric motors from tiny trolling motors to large inboard electric motors of several horsepower. The prospective battery purchaser should be aware that the majority of the LiFePO4 batteries manufactured in China are of very poor quality and correspondingly provide poor overall performance.

These batteries will also have a shorter life than a quality LiFePO4 battery. Only high quality LiFePO4 batteries should be used by the electric boat owner so as to provide peace of mind in terms of battery reliability.

If a battery manufacturer is not prepared to stand behind their own products by providing a lengthy factory backed warranty then it is best to steer well clear of these companies so as to avoid any possible headaches in the future. For example some manufacturers will simply crimp end terminal caps on the cells while other manufacturers will spot weld or even fully laser weld the cell ends.

Obviously a cell which is merely crimped will be cheaper to manufacture than a cell which is fully laser welded. By the same token the crimped cell is also more prone to fail prematurely due to slow ingress of moisture, humidity and other atmospheric contaminants which in a laser welded cell are totally excluded from entering the cell for the life of the cell.

Video one is an introduction to building the frames. When building frames the typical method is to use a drawing of the frame as a guide. I am using this system that will automatically give you the shape of the frames by building them on a jig using 3 points. Because the laser cut parts are exact copies of the edges of the frame what you will be doing is lining up the edges of the frame parts.

Part 2 i use Super glue to glue the joints between the frame parts because all i want to do at this point is get the shape of the frame. On another build i used 5 minute Epoxy to build the frames and that worked out just fine. Using the Epoxy one little draw back is when toy are lining up the edges your fingers get glue on them and you end up with epoxy on the face of the frames.

Another tip is to let the wood glue sit in a container and it will thicken up. Once the glue gets thick it also becomes tacky and you do not need to clamp the parts together. Epoxy does not work on all types of wood. As an example at first the Epoxy held but a couple years later the epoxy failed. There are woods out there that are oily or have their own resin in the wood which are not compatible with epoxy.

This is why for any job like gluing the frames together i will use Wood glue as my first choice. The finer the grit the less you can remove in on pass, so it takes several passes through the sander. More passes more time and more cost added to the sheet. Wooden ship model building is a hands on process of working with wood and finishes are part of the process.

Wood will move with changes in temperature and humidly so the building is a process of fitting and sanding parts to fit are part of it. Personally i like scraping the surface as you can see in this next video.

I only clean the char on the inside because once the hull is assembled it is harder to sand the char. One concern was the difficulty of cleaning off the char and another concern was when sanding off the char you are removing wood and the parts would no longer fit. None of these were true the char is only on the surface and not "burned" into the wood unless the actual cutting was done wrong because you can burn the wood but a good laser cutting will not have such a problem.

Now as far as sanding off to much wood to the point the parts will no longer fit is another myth. When sanding or scraping off the char you are maybe removing just a few thousandths of an inch, besides that when i set up the laser cutting file the cut was offset a few thousandths so you would have to literally grind off quite a bit of wood to get a bad fit between joints.

PART 8 This is about building in a jig. Just because you are using a jig it is not fool proof and you can end up with frames out of place. PART 9 Back in the day when Harold Hahn introduced the idea of building a framed hull in a jig many builders jumped on the idea thinking it would solve all the problems of setting frames.
