Prowler 1500

The Prowler 1500 is a semi-displacement power catamaran design, following a more traditional style in comparison to some of the more modern power designs such as the growler series.

Prowler 1500 Study Plans - PDF Coming Soon

The bows have been kept quite square and sharp, and the cabin features large wrap around windows and angular styling. The foredeck runs forward to the front of the bridgedeck providing a wide spacious area for sunbathing, enjoying a glass of champagne or giving storage space for dinghy or other cruising toys.

The layout is open plan and offers a surprising amount of interior space and accommodation due to the Prowler’s wide hulls—significantly wider than that of her Alaskan sisters. This extra width does allow a little more freedom when configuring the layout and combats the ‘stuffy' enclosed feeling that being down in the hull can bring.

The Prowler 1500 is a large displacement hulled cruiser that will sleep 4-86 family or friends comfortably. She has a very large light ‘n airy galley and saloon allowing full-size appliances. The cockpit is also designed for entertaining, cooking, toys, and fishing. The flybridge is generously laid out which could also covert into a premium berth. The upper deck also has wide possibilities for storage or entertaining.

The Prowler 1500 is a large displacement hulled cruiser that will sleep 4-6 family or friends comfortably.

Radical Bay 1060

The 1060 would make a fantastic small cruiser and couple safely carry you and your crew to any tropical destinations.

Radical Bay 1060 - A3 Study Plans

Radical Bay 1060 - A4 Study Plans

The Radical Bay 1060 is the bigger sister to the 8000, and provides that little step up in accomodation, space and performance. Again a standard rig is an option, however the composite bi-plane carbon masts are still the recommended configuration.

Unlike the Radical Bay 1060 has a spacious hard-floored cockpit with ample seating for all the family and friends and comes with the option of either single aluminium mast or bi-plane rig.

The Radical Bay 1060 has a very usable interior with a tidy galley area, a head and shower aft port-side and accommodation for 6 people - 2 double and 2 single bunks. A small dinette doubles as the second double bunk with a fold down dining table.

The Radical Bay 1060 utilises strip planking construction to provide a cheaper, quicker and easier build. The boat can be transported in a shipping container in three sections should transportation be necessary. Whether you're looking for a simple, fun weekender or a light live-aboard, you cannot go past the Radical Bay 1060.

Radical Bay 800

Schionning Designs Radical Bay 800 is a small weekender or coastal cruising catamaran, that still has enough sea-keeping ability to cross an ocean or two. The bi-plane rig provides amazingly easy sailing. which truly must be witnessed to believe.

A standard rig is an option and is at the owner's discretion. There are a number of Radical Bay 800's on the water, and many have done very well in racing events in Australia and Asia.

For the Radical Bay 800, I have chosen a simple hull form, with a vee section forward to stop slamming running aft to a flat exit to reduce hobby horsing. The asymmetric hull shapes as used on most of our designs benefit the boat in a number of ways.

The layout is surprisingly comfortable for such a small cat especially with good speed being kept in focus: the fwd bunks are comfortable and an aft "double" can easily sleep two friendly people. I have added a cockpit in each hull, the cabin offers some protection but mostly to have a comfortable sitting position with good visibility protected from those annoying unexpected splashes that sneak up through the tramps now and again.

She is definitely the future, an amazing looking, fast, exciting, simple and cheap to build cat. No such thing? True until now. She is a very safe, easy to handle coastal cruiser, a little cat a couple could live on for months at a time and yet easily demounted to transport anywhere if sold.

Arrow 1201

The Arrow 1201 promises the same sailing experience and performance of the 1200 version yet with a revised interior and cockpit giving more options.

Schionning Designs International presents the Arrow 1201 Catamaran,

The Arrow 1201 promises the same sailing experience and performance of the 1200 version yet with a revised interior and cockpit giving more options.

The Arrow 1201 has the same layout to the Arrow 1280s : 4 berths and 2 heads. Other layout options include twin owner’s hulls, or Stbd owner’s hull with Port guest hull, or 5x berths & 1x head/shower. See more details showing the 3 cabin version with stbd owner’s hull and port guest hull. The helm options are: Central Raised Helm (shown), bulkhead helm (twin or single), or dual tiller steering. The Stbd berth has been widened to be a full queen with great volume inside. This required a reshaping of the cockpit compared to the Arrow 1200. The Navigation table is now cleverly in the saloon allowing closet shelves below in port hull.

kit materials' Contents

So if you order a Schionning kit, what exactly is going to arrive? See an overview of the materials you will receive, and what each is used for during the build process. Fibreglass cloth or tapes? Microspheres, Microballoons or Microfibers? Take a closer look and you can answer these questions.

Our Schionning Kits are a no nonsense, common-sense approach to building a boat. We offer great service, fast delivery and access to anything you could need for your boat straight from the supplier to your door. Our construction plans and kits are sold with 100% professional boatbuilder support via phone and email, any time you're unsure or just need a second opinion, we're here.

Our kits contain all of your basic materials to build your boat to a faired shell stage, ready for painting and fit-out. We have sail-away costing estimates available for all of our standard designs, and this will give you an accurate idea of the overall cost of your project. This costing varies depending on your level of finish, as you can imagine different options vary greatly in price.

Below is a quick glance at what your Schionning Kit will include and what each item is primarily used for, we hope this is helpful and if you should require more detailed information please don’t hesitate to contact our office.

What do I actually receive?

DUFLEX PRE-LAMINATED PANELS

DuFlex pre-laminated panels are the main and most important material used in our kits, predominantly in the flat panel designs, however they are used in Strip-planked designs also, though to a lesser extent. These panels are 2400mm x 1200mm and are CNC routed to speed up build time on our Wildernes X Series, as well as some of our power designs. For internal furniture, a paper honeycomb core is used instead of the end-grain balsa wood core that is used for main structural areas. The use of this is purely to save weight in the shell and therefore produce a faster, more responsive catamaran.

KINETIX LAMINATING RESIN & HARDENER

Kinetix Laminating resin is used on all of our designs and is used for laminating the strip-planked areas, so round-bilge designs will use it more often whereas our flat panel designs not as much.

The reason we use Kinetix is that it has a much higher heat resistance than West System epoxies and for larger surface areas that will be in direct sunlight it is the safest solution.

The Kinetix resins are mixed by weight/volume at a mixing ratio of 4:1.

WEST SYSTEM EPOXY RESINS

The West System range is the most widely used composite epoxy system in Australia and the World when it comes to marine applications. Trusted and recommended across the globe, these products are used for most of the gluing applications involved in your build. Pumps are sold for mixing the resin and hardeners, at a ratio of 5:1. The pumps ensure that 1:1 pump ratio will equate to exactly 5:1 resin to hardener. West System hardeners come in a variety of drying speeds from Fast to Slow and everything in between. This is important when certain jobs require more or less drying time, or when working in different environments and temperatures. The West System fillers are Microlight, Microfibres and Microspheres and these are used for either fairing, gluing, filling or coving in corners etc. These powders are mixed with the resin and hardener to form a putty of desired viscosity.

FIBREGLASS TAPES (DOUBLE BIAS)

These double bias fibreglass tape rolls are used for the joining of panels in our flat panel designs, or in round-bilge designs to a lesser extent.

Anywhere that DuFlex panels need to be joined, tapes will be used.

The smaller rolls come in different widths for ease of use and to save time on cutting larger rolls of cloth.

CARBON FIBRE CLOTH

Carbon fibre is used on a number of our Schionning Catamaran Designs and can be incorporated into any design to save on weight and increase the performance capabilities.

Carbon comes in unidrectional and double bias, however is much more expensive than standard fibreglass (as one might expect). It is very similar to work with, however the resin choice may change when using carbon.

FIBREGLASS CLOTH

Fibreglass cloth is the strength and stiffness that holds your boat together, this is used in most areas for strength and is used in a variety of techniques depending on the area or job that is being performed.

Fibreglass is one of the most widely used materials for low weight and high strength properties.

The Kit Process

Building your own boat can be a daunting prospect, however to demonstrate each step in the kit assembly process, we've created this guide for you to study. As you can see our kits are the ultimate in building efficiency and have been streamlined over 30+ years to ensure that you're on the water faster and with less effort.

How does it all go together?

STEP 1

The first step to building your dream catamaran begins with a strongback – this is a square frame used to position the temporary frames that will be used to form the hull shape. This frame will be set up and must be square and accurate, a string or laser level can be used to achieve this.

STEP 2

Once you have released the pre-cut frame panels, they are erected along the strongback in sequence. The hull panels will be laid over this framework to form our hull shape.

STEP 3

Here we can see the hull has now been taped and glassed, ready for turning soon. Once this has been completed the hull will need to be rolled over and the process repeated to produce the second hull. The use of flat panel construction techniques and the time-saving element of pre-cut kits really becomes noticeable. Having this head start is invaluable and could save almost 1000 hours on your build. (Wilderness 1100 design shown.)

STEP 4

The fairing is now complete, this is done using a filler compound mixed with our West System epoxy resin and applied to the surface of the hull. This process is to ensure that when painted the boat will have a smooth and glossy appearance, and as a general rule the more painstaking the paint-job and fit-out, the higher your resale value.

STEP 5

Now comes the turning of the hull! There are many different ways to do this, some involve cranes or complex equipment, however the smaller designs can simply be turned with a few extra pairs of hands, or a block/pulley set-up. Once both hulls are turned the tops of the bulkheads will be used to join the two hulls, and then the bridgedeck component will be installed underneath.

STEP 6

The hull now turned, the second must be positioned and aligned before the large bulkhead panels are used to fix these together. Once this is complete, she will start to look like a catamaran!

STEP 7

The forebeam is now installed along with the striker attachment fitting, as shown above. The bridgedeck is installed shortly after and taped onto the bulkheads with webs installed, this now completes what is a quite stiff and strong platform to work on.

STEP 8

Now that the bridgedeck is in place, the forward webs and dash will be fitted. At this stage, all furniture and internal work begins, with the main panels left off for ease of access when working.

STEP 9

The internal furniture is now installed, if you chose Kit Option 2, this furniture will be pre-cut to your previously decided upon layout. If you chose to receive blank panels, this is the period in which your internal living areas are to be built. This construction uses paper-honeycomb Duflex panels, as these are superior in weight when used non-structurally. Cabin soles, engines and daggerboard cases are also now installed.

STEP 10

The transoms and cockpit area are now completed, along with the targa bar, if you’ve chosen this option.

STEP 11

The next step is our hull-to-deck joins, side decks and close the shell. As you can see strip planking methods are used here to ensure a pleasing design to the eye. This technique is not difficult and the planks are once again glassed in place to ensure again stiffness and strength.

STEP 12

The cabin roof will have been built seperately from the boat, and dropped onto the bulkheads when needed. The cabin sides are then installed and we have a cabin. The next step is to carefully mark our window lines and get cutting.

STEP 13

Cutting of hatches, portlights and your saloon windows is now done, edges must be cored. Interior and exterior painting can now be completed after fairing.

STEP 14

Fairing is now completed and your final finish needs to be achieved. How extravagant you want to get with paint choices and decals is up to the owner and the project budget.

STEP 15

Fairing is finished up and the shell is ready for painting. This is as far as the Schionning kit will get you – from this point on the finishing touches, rig and deck hardware, equipment and appliances must be installed along with finishes such as carpet, roof linings etc. We can supply you with a rough sail away estimate based on other finished projects of a similar size when enquiring about a design, so don’t hesitate to email us if you’d like to investigate further, the build process can take a while to get your head around and we certainly understand that.

STEP 16

Once installation of major systems and finish has been completed the boat can be launched. Again this is something that should be planned beforehand however our designs can safely be loaded onto a flatbed semi-trailer sitting solely on their bridgedeck without any problems. So as long as you’re within a reasonable distance, a simple truck hire should be sufficient for your launch.

STEP 17

Once the mast is stepped, its time to go sailing!

THE LAUNCH

Building your own boat is a rewarding experience and you’ve built a valuable asset on which you can make a considerable profit. If you have any questions regarding build options or designs, please contact us by email, or via the contact page.
