Designer's Briefs


by Derek Ellard Scruffie Marine Designer




In designing the Stornaway Weekender I had one simple aim in mind:

To build the perfect small cruising yacht, the best in the world.

 

To this end, I wrote a set of criteria. It was the boat should have or be...

Safe, seaworthy and a joy to sail.
Able to comfortably withstand winds in excess of 30 knots and seas in excess of 2 metres.
Able to support 4 adults and their gear when fully swamped (7 adults in the open version.)
Very good self righting properties.
Excellent stability characteristics.
Good directional stability and a steady near neutral helm.
Sail herself unaided in most conditions.
Use the mizzen to heave to and reverse the vessel.
Flat packed and shipped anywhere on the planet with ease.
Capable of being built with minimum tools and facilities.
Able to be rowed or motored efficiently.
Able to operate all sail or power controls without leaving the tiller.
Able to rig, launch retrieve and sail single handedly.
Able to easily raise and lower the mast, reef and anchor from the centre of the boat.
Able to brail up the mainsail instantly or completely drop the sail in under 30 seconds.
A boomless main for safety.
A comfortable cockpit and cabin with room to sleep 4.
Space for a cooler, port-a-potti, stove and sink with ample water.
A large canvas hatch.
Ample room for storage.
Low topsides for easy access.
An efficient anchor well.
Self-draining in the cockpit.

Able to be built by a home handyman in under 6 months part-time.
Cost less than $10,000.
Have a draught of less than 2 feet.
Easily trailerable with a 2 litre car.
Able to be rigged and launched in under 20 minutes.
Main yard long enough for boom or awning.
Able to stow all spars in the length of the boat.
Elegant, timeless traditional lines which will look good for generations.
Will hit 6 knots, ghost effortlessly in light airs, take the roughest conditions in her stride and never, ever let you down.

And did we fulfil the brief? Undoubtedly, the boat is a great success and 20 were sold in the first year of full production.

Three years on and Stornaways have been subtly improved and updated. The new Cuddy Cabin Version allows more room in the cockpit but leaves the forward bunks intact. The Camper shares the same layout. New keel and rudder profiles, introduced in 2000, have further enhanced windward ability. An excellent little ship is now even better.





In designing the Shimmy I had one clear objective in mind:

To produce a simple 12 ' family boat that was superior to anything on the market.

The new boat had to be safe & stable enough for beginners or retirees and forgiving when they get it all wrong. Modestly rigged, Shimmy still had to sail well, yet be easily rowed or outboarded. Here, then, in no particular order, is the final list of requirements I set for my brief.

 

The new boat had to have or had to be:

The easiest self-assembly boat of its kind in the world.
Available ready to sail.
An ultra simple, foolproof, boomless, lugsail rig for safety.
Able to be rigged and launched in under 10 minutes.
Able to sail safely in winds in excess of 20 knots and swell of 2 metres.
Able to seat 4 adults in comfort and have enough buoyancy to support them inside the boat when fully swamped.
Enough room for 2 people to camp overnight under a boom tent.
No centreboard or daggerboard.
Neat, efficient stowage for 2 batteries and a decent pair of oars.
Excellent general stowage capacity and both mast and spar should fit inside the boat.
Designed for electric power as well as petrol.
Suitable for commercial operators, particularly in resorts.
Flared forward sections for a dry boat.
Self-draining at seat level.
Easy on the eye but not another clinker clone.
Easily towable with a 1500 cc car.
Able to be rigged, launched and sailed single handedly.
Brand new, fully rigged, had to cost no more than $4,000 as a kit.
A folding bimini top or awning for the tropics.
Draw less than 16 inches (400 mm).
Easy to repair and maintain.
Able to be efficiently reproduced in fibreglass.
Last, but not least, a pleasure to own.

Clearly compromises had to be made to fulfil the very demanding criteria, yet we did it and we've sold 32 in the first three years of production.

Obviously Shimmy is not going to be the fastest thing on the water yet she will reach all day at better than 4 knots with a wonderful steady helm and get you home safely in weather that sends other boats scuttling for shelter.

Annette and I recently sailed our Shimmy in a blustering 20 knots with plenty of whitecaps on a short lumpy chop. With a reef in the main, she was as steady as a rock and although a fair bit of spray came on board most was quickly drained away through the seat level scuppers. At the end of the day only a couple of buckets full were left under the floorboards. It was a wonderful, exhilarating sail and we were both very impressed with the little ship.

 



One of many questions we ask our customers is simply this :

“What kind of boat do you want?”

The answers are, of course, many and varied but quite naturally most people want as much boat as possible for their money. Enter the Scintilla 24 - designed to be the reference point for traditionally rigged trailer sailers - the benchmark.
A boastful claim indeed - empty unless we can back it up - here's how.

Performance
Handing
Building
Safety
Accommodation

Performance - with a standard yawl rig the scintilla 24 will surprise you with sparking performance and sheer versatility. She'll ghost along in the faintest of zephyr yet quickly hit 6 knots or more when the breeze pipes up. A long straight keel, fine underwater lines and a long run to her graceful counter stern equates to a steady helm and an easy motion even in confused seas. Scintilla's low aspect ratio lugger rig means more power low down for less heel and greater stability. This is a modern interpretation of a sail plan honed to perfection over centuries of hard workboat experience. Upwind, as with all traditionally rigged boats, ease her off a point or two and she'll reward you with very good speed and excellent ground covering ability. Downwind she'll look after herself with little or no help from the skipper.

In heavier weather two reefs in the main, one in the mizzen and a storm jib will do nicely. And in case you're caught out in something over force 6 then the reefed mizzen and storm jib will still balance the ship while you bring her home. Coming in to harbour, roller reefing on the genoa and a topping lift on the mizzen allows for delicate manoeuvres under sail. A neatly fitted 4-8 HP outboard, in its own well to starboard, powers you along on the smell of an oily rag and doesn't hang off the stern on an ugly bracket. As an example, under power a 4 HP 4-stroke will cruise at 5 knots. An 8 HP will allow a top speed of 6.3 knots All this adds up to exceptional seaworthiness and exceptional handling without undue histrionics.

Handling - one word will do. Easy. Let's start with rigging and launching - do the whole thing by yourself and if you take longer than half an hour something is not right. The mainstays are already set up, the mast is raised and the forestay and genoa halyard cleated down. The main is up (or down) in seconds and the unstayed mizzen mast simply drops into a slot. Easy! Once afloat all sheets and controls can be adjusted without leaving the tiller. The motor tilts up and out of the way and you can heave-to quietly at any time by simply sheeting in the mizzen and furling the others. Despite a relatively long keel, a Scintilla will turn readily and tacks smartly. That same long keel and an exceptionally shallow draft means she'll power on to windward in two feel of water and hold steady while you walk forward to anchor of reef. Easy !

Building - while other boats can offer some of the features available with a Scintilla, almost none can be built at home from a kit of engineered components. Our RTA (ready to assemble) kits offer not only incredible value but genuine ease of construction. A Scintilla 24 can be framed up in a week and ready to float in another two. Of course fitting out will take a fair bit longer but the point is that very quickly the boat parts become a real boat. You don't have to be an economist to work it out and you certainly don't have to be a shipwright to build it. After nearly a decade of pioneering kit production in Australia we've pretty much got it all sorted.

Safety - our boats are the safest - no arguments - here's why. Firstly, the virtues of a displacement hull, generous beam, wide side decks and proven, simple rig need no endorsements. Add to that lead ballast right down near the bottom of the keel and a boomless main and you have a pretty foolproof combination. These predictable boats will spring no nasty surprises.

Secondly, our boats are extremely tough built with interlocking frames and bulkheads enclosing multiple watertight compartments along the whole length of the ship. In short, we've done every thing possible to ensure the safety of passengers and crew.

Accommodation - OK which trailer sailer can sleep six comfortably, (two under canvas in the cockpit) accommodate a shower, marine toilet and a decent sized galley without looking like a floating caravan? Which traditional 24 footer, seats six in the cockpit, six down below and two on the foredeck? And which can be had in survey to carry eight passengers plus crew? nd can an inboard diesel be almost disappeared beneath the cockpit sole? And is the cockpit self-draining? And is there good sitting headroom? Custom interior?

Answer:

Scintilla 24

So what more do you want? Its got to cost less than any other new boat of its size and type, right? You've got it.




Scintilla & Secret - A Brief Comparison
These two crafts have been developed from separate criteria and although built using similar systems, are quite different.

Scintilla is the largest practical trailerable yacht we manufacture. She is big, comfortable, exceptionally spacious and numerous cabin variations are possible. She does need a two axle, braked trailer and launching and retrieving is certainly easier with two people. The yawl rig ensures easy single-handed sailing, even in atrocious weather. The boat is nonetheless quick, being more than a match for many similar sized boats, and certainly steadier and more sea kindly than most.

Secret was designed primarily for performance and looks. Accommodation is basic but comfortable, being ideal for two but two more can sleep under canvas in the cockpit which seats six comfortably. Her keel is relatively shorter, her ballast ratio higher. The hull form is more rounded with a flatter run aft and the rig is a powerful gaff cutter, an electric auxiliary has been specified. Two versions are available, a Weekender and a "R"(racing) type, both easily launched and retrieved single handedly.
The Secret weighs around 600 kg and thus can be towed by a 2-litre car. Scintilla, by comparison weighs in at around 1 tonne and although our 2.4 litre pickup tows it comfortably.
