Growler 1500 GTR

SDI Growler 1500 GTR Power Catamaran: modern, sleek, fast, fuel efficient; ideal for long range cruising and live-aboard.

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

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).

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

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.​

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.
