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.

Sea Shanty 1600

SDI Sea Shanty 1600 Power Catamaran Schionning Designs International

Sea Shanty 1600

The Sea Shanty evolved as an idea of Jeff's to create a large stable cruising platform, able to carry enough of the cruising toys to make it a real home away from home. The huge cockpit and multiple cabins make the Shanty into a real palace on the water. Motorbikes or a small car could be loaded via the aft ramp, if desired.

DESIGN FEATURES

A world cruiser, she has a generous payload to afford luxury.
Not all of the internal furniture is built in, household items may be used.
Moderate cruising speeds from 9-12 knots up to 24 knots.
Combination of strip planking and flat panel construction.
Fantastic for those that wish to escape it all and explore the globe.

CONTACT US FOR MORE INFO

“Sea Shanty”, the name conjures up visions of thatch, sand, and crystal clear water. Simplicity, practicality, and the great outdoors, this is exactly what she’s about. The Sea Shanty is based on the hull form of our very successful 16m Ferry built in Australia and used in Vanuatu to carry passengers around the islands.

While she was being built, Lorraine and I spent some time cruising on our Trimaran and we kept coming back to the idea that the Ferry would make the ideal platform for a comfortable world cruising home.

Whilst we love life aboard, we also miss our toys and comforts, pets, family and space whilst cruising. We like to keep active and felt that a large seaworthy platform with simple but stylish accommodation and a large outdoor area was very desirable.

So the design evolved. Where the Ferry needed decent displacement to carry 75 passengers the Sea Shanty needs the displacement for home comforts plus fuel and water for extended ocean passages. As a passage maker, speed was moderated to a comfortable mile eating 12 – 16 knots and a bar crossing sprint of up to 20 knots.

Construction is our proven Schionning build system that has been producing beautiful catamarans for over 20 years - the high tech composite materials, including pre-laminated panels and some strip planking (to achieve the soft curves of the design). West System epoxy and S-Glass (lighter yet with the same strength and stiffness of standard fibreglass) cloth is used for the shell construction. Carbon options are certainly available and quite popular, however these choices need to be made by you the owner, to produce an end result that is within your chosen budget.

CONTACT US FOR MORE INFO

As a designer you’ve got to love those few clients who want something different and way out there. The Growler 1500 GTR design concept is for one of our loyal repeat owners, this being his fourth Schionning and happily loved them all, why wouldn’t you, most of them new cutting edge sailing cats but now looking at the growing power cat market he’s again thinking way outside the square.

We are using the new Whisper hull form we have been developing over the last few years, shallower draft, lower drag ratios and yet still having the superb soft ride and sea keeping ability of our VT series. She has generous hull beam giving huge accommodation in the hulls and high load values. Styling follows our G‐Force trend with the reverse bows, but has the sleek yet aggressive Growler Power Cat look, flexing those muscles.

Growler 950 VTR

Growler 950 VTR Power Catamaran - SDI - Schionning Designs International

Growler 950 VTR

The Growler 950 VTR is an evolution of ideas from various clients asking for the same overall design concept. A modern, sleek power cat that is fuel efficient, is ideal for overnighting and weekending and can be trailered home for storage (with a permit in some states).

CONTACT US FOR MORE INFO

This has lead to the development of the Growler 950 VTR. Her sleek looks are sure to turn heads in any anchorage or the local boatramp, and with just two 90hp outboards she will get you there in no time – and in comfort!

The patented and well-tested Vapor Trail hull shape is known for its wave-piercing characteristics - cutting through the heaviest swell, and her high bridgedeck clearance will ensure zero slamming.

The forward cockpit really opens up the aft area into a platform ideal for fishing (game chair mounted between the outboards?), swimming, sunbathing or just for deck chairs and socialising.

The Growler 950 VTR is available in a Stealth version and a Flybridge version. You can see these displayed in the photo gallery.

Growler 880 GTR

Growler 880 GTR Power Catamaran Exterior CAD Designs - SDI - Schionning Designs International

Growler 880 GTR

SDI Growler 880 GTR is Fast, Fun and Ballsy, our new Growler 880 GTR power cat is perfect for week‐ending and coastal cruising.

You’ll be very surprised at how much room is inside this ‘small’ cat – there is plenty of accommodation for a big family, including a good sized private head and shower. If you’re more likely to enjoy fishing with a bunch of your mates, we’ve got that covered too.

CONTACT US FOR MORE INFO

We have used our new “Whisper” hull shape on the Growler 880 GTR, a development from the VT hull form using the wide hull beam but with “soft” V entry giving a similar seaworthy ride but having the advantage of shallower draft for shallow areas and beaching.

Quick to plane, we are using 115hp outboard engines on Stealth 1 she will cruise comfortably at around 18 to 20 knots with a top speed of 28 – 30 knots expected, but if you use more power, you’ll get more speed. The Whisper” hulls will deliver incredible comfort and safety, even in rough sea conditions, much like our well proven VT’s.

The Schionning Designs Growler 880 GTR wide hulls offer very good volume inside providing unusually good accommodation in a cat this size and yet still offer very good fuel economy.

There is an excellent building project blog by The Boatbuilding Boys, Troy Smith and partner Brad in Sydney, NSW - see their project and progress here.

Prowler 1040 GTR

Prowler 1040 GTR Power Catamaran - SDI - Schionning Designs International

Prowler 1040 GTR

The Prowler 1040 GTR looks quite like the Growler VTR, both sharing the new ‘Schionning’ sleek, stealth styling above water but the underwater shape is quite different. The Prowler GTR has a standard semi-displacement hull shape.

CONTACT US FOR MORE INFO

This is a very efficient hull that travels through the water so doesn’t plane or achieve the very high speeds of the Growler but she is however more economical for longer distance travel and she’ll cruise comfortably and efficiently from 0-22kts.

The hull is rounded so construction uses strip planking for the hull bottoms but the rest of the boat is supplied in a flat panel pre-cut kit for easy building by anyone.
