Solitaire 1740
Solitaire 1740
Schionning Designs presents the Solitaire 1740 cruising catamaran, a design intended to challenge the large production manufacturers in Europe with very heavy products.
The Solitaire was initially intended as a production design, but is now available as a pre-cut kit and this will ultimately mean she is lighter, stiffer and with as much room as the big production vessels.
Her primary design feature is an efficient performance sailing catamaran with high bridgedeck clearance and angled tunnel panels to minimize slamming. She has a strong beam / length ratio and strong sail area / displacement ratio. Yet the Solitaire has our best interior volume ever allowing multiple versatile layouts and the payload to compliment it.

The Schionning Designs Solitaire 1360 Multihull Catamaran offers similar internal comfort and space to the production boat competition, but she is far lighter, stiffer and stronger with better waterline beam values and higher power to weight ratio.
This is a serious blue water cruiser capable of taking you around the world with high mileage daily runs in comfort and safety with minimal slamming.

On the propulsion side she has an efficient alloy mast and boom fully battened deep roach main, single line main reefing in the boom, roller furling headsail, and furling screecher on the prodder. A para-spinnaker finishes off her downwind capability. A simple, fast, and efficient rig.
Engine power comes from two 20 kW electric motors and a single 80 HP shaft-drive with folding props set comfortably forward for easy access from inside the hulls. This hybrid system will power all the equipment and air conditioning. There are large water and fuel tanks to ensure that the vessel is fully self-sufficient while away from the dock.

Radical Bay 800
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.

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.

Tracer 1500TRi
Tracer 1500TRi
Trimaran
Introducing the new 1500TRi, the first member of the new Tracer Series of performance cruising trimarans from Schionning Designs. Designed to blend the performance of a trimaran with liveable interior accommodation and create a stable, aesthetically-pleasing cruising platform that can take you anywhere in the world.
The 1500TRi exterior is a little different to many of the standard trimaran designs we've become accustomed to.
Large spacious cockpit areas are located on either side of the cabin, with the helm stations positioned wide on the aft beam giving excellent visibility forward, as well as clear sight of sails and telltales. Lines run aft to the helms with winches and sail controls mounted close by for ease of operation.
The large cockpit areas will be fantastic for swimming, sunbathing, storing dinghies & equipment plus just a great spot while underway.
A 19 metre mast can be rotating carbon or a standard alloy option, but with the performance aspect of this design carbon is recommended. She has fixed rudders on the floats, however this will not be an issue and she will still be able to beach easily. Kick-up rudders are an option if desired and depending on your intended use for the boat. A single 30-40HP diesel is the recommended motor option.

G-Force 2350
G-Force 2350
The G-Force 2350 is currently the biggest Schionning design to date (not including concept designs) and one example is operating as a charter vessel in the Caribbean.
Measuring in at a staggering 23.5 metres, and 10 metres wide - the parameters have really given the design team a blank canvas with which to create the flagship of our company.
This design is perfect for charter work, and one example of this design is currently working in Bermuda however it is customised and not a performance vessel.
The G-Force 2350 began as an exclusive custom design however is now available for amateur and professional construction. Any of our recommended Schionning builders on the production page could deliver a beautiful example of this design.
