Catamaran Building Blog Manual
Leopard owners all have different plans and ambitions with their sail or power catamarans. Some take their yachts on extensive travels, others stay closer to shore. The most important part of travelling farther away is being able to get your engines Blog Catamaran Building Manual serviced. All Leopard catamarans are powered catamaran building blog manual Yanmar engines.
On buipding latter, the drive catamaran building blog manual from a Catamaran Building Blog Manual sail-drive to a V drive, as the HP engines are not available as a saildrive. The largest saildrive by Yanmar is 80HP, and this is basically the same engine as the 57HP but with a turbo intercooler to get the output to 80HP.
However, this comes Catamaran Building Blog Manual at a cost as the price for larger engines blot higher as manuql. Once a catamaran reaches hull speed, it reaches the Blog Building Manual Catamaran point of diminishing returns: if you push the engine to higher rpms and buildong go faster, the fuel catamaran building blog manual goes Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual up exponentially, and the boat-speed goes up just a little bit. Your yacht also pushes a much catamaran building blog manual wake and Catamaran Building Blog Manual you see the stern of your Leopard go buildiing.
Leopard sailing catamarans have a displacement hull, not a planing hull, otherwise one could hang 2 x HP outboard engines on the back and go really fast!
On all Leopard sailing catamarans the engines are located in Building Catamaran Blog Manual Catamaran Building Blog Manual the aft transoms, separated from the aft cabins by the aft bulkhead. Our engines and saildrives are reverse-mounted, that means the sail drive Catamaran Building Blog Manual sits in front of the engine. This does not change anything on the dynamics of the propulsion, however, the advantage is that there is much more space in the aft cabins.
The fuel tanks are located in polyethylene plastic fuel tanks underneath the bunks. If Catamaran Building Blog Manual ever the need arose to remove the tanks, it would be a relatively easy task. The weight of the engines and tanks is Building Manual Blog Catamaran carefully balanced with other equipment on board so that your Leopard will have an even trim. Power catamarans are very weight sensitive, and Catamaran Building Blog Manual Catamaran Building Blog Manual due to the fact that the engines on the 43 PC have an output of 2x HP and the 51 PC has 2x HP, the transmission to the propeller is through a straight shaft.
The insulation of the engine bay, the liner catamarann the engine hatch ensures a very dampened noise level while lbog. Leopard offers the optional bow thruster only on our flagship, the Leopard On smaller Catamaran Building Blog Manual Leopards there is simply no need catamaran building blog manual it: with catamaran building blog manual that are 20 or more feet apart, Catamaran Building Blog Manual Catamaran Building Blog Manual and a bit of practice, you can dock a Leopard quite easily.
The first production catamarans with electrical engines were launched 15 years Manual Blog Building Catamaran ago, and the fact that no production builder is currently using electric drives is a statement that the available technology is not ready Catamaran Building Blog Manual for marine applications.
However, Leopard is keen on less fossil fuel usage and solar panels can be fitted on any model Leopard Catamaran. Lead Catamaran Building Blog Manual Acid are the standard type batteries offered on Leopard catamarans, but most Leopard buyers opt for the upgraded AGM batteries. They were originally developed for military aircraft and power, weight, safety, and reliability were paramount considerations.
As ofLeopard offers Lithium batteries as an option Catamaran Building Blog Manual Catamaran Building Blog Manual on the Leopard Lithium batteries are the next step in battery efficiency. They are light weight, and they can be discharged much more than Lead acid and AGM batteries.
However, this comes at a cost: Lithium batteries are catamaran building blog manual. At present, this catamaran building blog manual not possible on our catamarans.
As technology advances, we expect to offer this on other models as. At Leopard Catamarans we believe in tried and tested systems. The technology found on Leopard catamarans can be easily serviced and maintained with common Catamaran Building Blog Manual Catamaran Building Blog Manual knowledge of systems. If your Owner Manual does not answer your questions, Leopard has an experienced and qualified Technical Department on stand-by to support you with anything you made need as a Leopard Catamaran Owner.
Where are the engines and fuel tanks? Differences with the power Catamaran Building Blog Manual catamarans The engines on board the Leopard 43 PC and 51 PC are located underneath the aft beds.
Do I need bow thrusters? Are electrical engines an option? Should I upgrade to AGM batteries? Will I be able to run my air conditioning off of batteries? Peter Catamaran Building Blog ManualCatamaran Building Blog Manual rong> Wiersema. Subscribe Here!

The downside Blog Catamaran Building Manual is that it takes less time for marine growth to cover a larger fraction of your hulls, which can easily cost you a knot of two of boat speed.
So clean your hulls regularly. Tip: No one ever tells cat buyers that two hulls are more Catamaran Building Blog Manual work to maintain. Invest in a Hookah to save time. Stay light Cats derive their speed and fuel efficiency from their lightness. In Building Manual Blog Catamaran particular, keeping weight away from the bows and off the trampoline maintains forward buoyancy and reduces pitching.
NB: I used to keep Manual Blog Building Catamaran my kayak on the trampoline until it practically bounced off during a rough crossing of Backstairs Passage. One engine is enough Having two Catamaran Building Blog Manual engines is great for safety, but when cruising, one engine is usually enough. Running both engines will typically only add another couple of Catamaran Building Blog Manual Catamaran Building Blog Manual knots of boat speed. Here is why. Everything had to happen before Tuesday, us moving out, the hull, trailer, turning and the Goolwa Catamaran Building Blog Manual WoodenBoat Festival.
Also joining us was Graham Crane and the mighty Morgan Clarke. All six of us keen to see this through or Catamaran Building Blog Manual perhaps wanting to gawk at whatever happened.
At this time, none of us were sure of how this was to be accomplished. I am sure arguments at this stage could have wrecked the hull, or one of us. This control line was to be critical because the center of gravity is just below the lead, and once it began to turn, it was likely to swiftly run away from us.
Once the weight was off the building frame, we could cut that away and leave it free hanging, and use manpower Catamaran Building Blog Manual Catamaran Building Blog Manual and blocks to stabilise. This was very quickly achieved, a matter of thirty minutes. Once it was freely dangling, a control line was attached to the same lift point, but coming out from under the hull, off to the side and up. With some further effort, we stabilised it on this side, and swapped the main lift point to exit the inside of the boat, and lifted once Catamaran Building Blog Manual Catamaran Building Blog Manual again.
Within minutes, the boat was aloft and the trailer was being backed underneath. It was truly marvellous. All the worrying had distilled Catamaran Building Blog Manual Catamaran Building Blog Manual down to a brilliant series maneuvours. We were all beaming with pride and relief. Graham jumped in and designed a method to cap off the entrance flush so we could lock it all up, while I returned to the shed to tidy up for the new Catamaran Building Blog Manual Blog Catamaran Manual Building Building Manual Catamaran Blog Catamaran Building Blog Manual Catamaran Building Blog Manual owners.
That night I went to bed with the boat locked up and snug. First good sleep in months. Significant thanks must go Catamaran Building Blog Manual to Robert for picking up the lead, Morgan and Seb for their energy and great work, and Ian, Marrack and Graham for Catamaran Building Blog Manual being so level headed, strong and supportive. While I get my thoughts together to tell of the past six months, I dug up Catamaran Building Blog Manual a couple of articles that mean a lot to me.
Please take time to read them both, they appeared in the Australian Amateur Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual Boat Builder, both written by Robert Ayliffe. I chose to use 16mm ply and laminated Model Boat Building Jig Manual it on the hull. Because of the significant amount of rocker longitudinal curvature , the plywood would need to match the curve.
After setting out some plastic sheeting to prevent it prematurely glueing to the hull, I held the layers down with straps and cross bars while the glue cured.
This went well. The dowel is being used to clamp the ply shoe down as the laminating cures. I then attempted to glue the forward shoe down in one go�which I rapidly realised was a huge mistake. Not only is the hull curved longitudinally, but it also has a gentle Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual cross curve, which is a part of the Mark 2 design refinements. This cross curve meant the ply would need to be made Catamaran Building Blog Manual Catamaran Building Blog Manual to curve in a second dimension, which is effectively impossible when dealing with thick ply.
Therefore, the ply would need bedding in a Catamaran Building Blog Manual Catamaran Building Blog Manual significant amount of thickened epoxy to support it. And, you cannot mix up that much epoxy at once without it curing in your Catamaran Building Blog Manual Catamaran Building Blog Manual hands. After throwing away the first litre of mix, by scraping it off the hull as it hardened, I cut the sections Catamaran Building Blog Manual Catamaran Building Blog Manual Catamaran Building Blog Manual in quarters, with scarf joints, and set about fixing them one at a time. Just after I attached both fore and aft sections, Robert, Morgan and Seb stepped in and began the push to getting the boat turned.
It was their filleting, fairing, fibreglassing and finally Catamaran Building Blog Manual antifouling that got it turned and in the new home.
The bow section being shaped by a planer. Looking forward pre-fairing. The bow Catamaran Building Catamaran Building Materials Market Blog Manual Catamaran Building Blog Manual knuckle added to with epoxy mixed with high strength filler. A fall while off-trail bushwalking in October apparently tore a ligament allowing bones Catamaran Building Blog Manual to rearrange themselves in my left dominant wrist.
At the time I ignored the hurt, but during it got worse so I pursued a gradual escalation of medical intervention. That ended with an attempted reconstruction in November Once into the wrist with his knife, the Catamaran Building Blog Manual Catamaran Building Blog Manual surgeon discovered too much arthritis to proceed.
Apparently the left wrist is riddled with it, quite a mess. There are also signs my right wrist may also be arthritic. So he set about performing an arthroscopic cleanup. I could never sustain fairing with a torture board Catamaran Building Blog Manual Catamaran Building Blog Manual for long, and was sore for days afterwards. The whole thing has left me feeling pretty down and rapidly aged. I am writing Catamaran Building Blog Manual this in March feeling about as recovered as I will be from the arthroscopy and news of the reality.

So how did Catamaran Building Blog Manual turn the boat get turned over? Night crew. Once the design details and pricing are confirmed you are ready to place your order. The Catamaran Building Blog Manual kit arrives at your workshop door, usually by container, as a stack of 1. The shipment will normally include additional reinforcements, resins, and ancilary products as specified by your designer.
Unpack the shipment and stack the panels out of the way of the space where Blog Catamaran Building Manual the panels will be joined. The panels have a scarf join called a Z join that facilitate the join without needing tapes. The joining can be done with a heated Z press that cures the epoxy join quickly.
Alternatively they can be joined with clamping pressure. If the panel are are being joined with the Z press you will need an elevated work bench the full length of the longest panels you are using. Panels are being joined into a single long panel by painting the surfaces of the scarf join Catamaran Building Blog Manual Catamaran Building Blog Manual with epoxy screwing through plywood battens that have a release film applied to one side.
Once the joins are cured the panels are Catamaran Building Blog Manual stacked to one side until they are needed for the job. The inividual parts should not be cut free of the panels until Catamaran Building Blog Manual they are required. Bulkhead and floor panels will be needed before the hull sides and cabin top so they should be left to the front of the stack wherever possible.
When assembly is ready to begin the individual parts are separated from the panels by cutting the joining tabs. It is likely you will be building onto moulded hull bottoms that have been built from strip planking or another method of building moulded components. The process for building moulded components is described in another article.
As the panels are assembled onto the job you will need to apply glass tapes to the joins as specified in your plans. Panels can be surfaced and coated Blog Catamaran Building Manual Manual Blog Building Catamaran inside and out with high build while they are on the workshop floor to minimise fairing time once they are assembled to the Building Manual Catamaran Blog boat. The paint on the panels shown here has been kept back from the edges to provide a good bond for the tapes.
