British Registered Ship


For Sale  -  US$115,000



Here's what you don't get with Sunstone. There is no pressure water, no shower, no hot water, no water-maker, no generator, no freezer, no electronic autopilot. Nor do you get all the maintenance which goes with most of these items of equipment.

Here's what you do get with Sunstone. You get the opportunity to add your history to that of a unique yacht, which is robustly constructed, well maintained, a delight to sail and will always take care of you no matter what the conditions. You also get the pleasure of hearing daily in the languages of as many countries as you visit,

"Nice Boat!"









Sunstone (ex Deb, ex Dai Mouse III) is the first S&S design with a fin and skeg-hung rudder configuration. This design break-through is confirmed in Lines (2002), Olin Stephens' book of his own 49 favourite designs. Olin says of Sunstone that she '. . . has probably had the widest spectrum of usefulness of any designed by S&S.' He also says, '. . . her consistent winning record under a variety of rating rules has amazed all who have witnessed it.' Sunstone was also the home of her current owners, Tom and Vicky Jackson, for several decades and carried them around the world and from Alaska to Cape Horn.

Sunstone is a delight to sail. She is beautifully balanced and easily driven despite her heavy displacement. Many centerboarders have less than sparkling windward performance. This is not true of Sunstone, while she is also quick on a reach. Because her skeg-hung rudder is well aft, Sunstone is much more responsive and manoeuvrable than most long-keeled classic yachts. Though she does not have any current handicap rating, Sunstone has been officially weighed and measured for IRC. She has also been computer measured and inclined for IMS and so should easily be rated for ORCi. Sunstone has had an excellent racing record spanning 30 years under IOR, IMS, IRC and PHRF (see attached summary).

Sunstone has thrived through her wide range of 'usefulness' because of her break-through design and extremely robust construction. She was built by McGruer of Clynder in Scotland to Lloyd's 100A and launched in the Spring of 1965. The hull is planked in 1 1/4" Honduras mahogany, apart from four planks of teak in the garboards and teak bulwarks and covering board. All frames (on 9-10" centres), are large section, laminated afromosia, as are the wooden knees and floors, fastened with silicon bronze screws and stainless steel bolts. The hull is bronze strapped from the chainplates diagonally down to the rabbet. The hull is close-planked and splined. The robust construction and splining has allowed her to keep her brightwork finish as well as her fair hull shape.


The coach house sides are solid 1" teak, through bolted to the carlin and deck beam ends. The coachroof is ply, covered with resin impregnated cloth and painted. The deck is teak (renewed in 2000) on ply with ash deck beams. Planks all have long scarfs which bridge two frames. The skeg and rudder are laminated afromosia with stainless steel strapping. The spine of the boat is of composite construction. The keel is laminated with no scarfs. Throughout the central section of the boat floors are of stainless steel plate, bolted either to the very long stainless steel maststep or to the stainless steel centerboard case, which lies under the saloon cabin sole. The centerboard case extends through the lead keel to form a shoe under it.


Sunstone's principal dimensions are approximately as follows:


LOA 39'9"      LWL 29'     Beam 11'6"     Draft 5'3"/7'2"

Disp 22300lb                SA 710sq ft (main+100%fore)



Sunstone's construction and accommodation plans



In order to cope with the varied demands made on her there have been a few changes to Sunstone's original configuration. These have always been made to maintain her classic appearance and character without any changes to the hull or basic rig dimensions. Sunstone was originally tiller steered; that tiller is still aboard and can be refitted if the steering pedestal is removed. The cockpit was rebuilt in 1996 with a few minor changes to its configuration to make it more efficient and comfortable.


For serious cruising heavy bow rollers were added, which are removable for racing as is the boom crutch in the cockpit. Originally ground tackle was only rope and minimal chain with a large capstan on the foredeck. The capstan was removed and a modern windlass added on the starboard sidedeck over a chain locker for 60 metres of chain. These changes have kept weight out of the ends of the boat.


She has always had an aluminium mast; originally this had a single pair of wooden spreaders. The mast was replaced in 1992 with a double spreader configuration, but keeping the same mast height, while the very high boom was lowered slightly to give the mainsail a somewhat longer hoist. The mast has always had fore and aft lowers, but it is possible to remove the forward lowers for racing and substitute a babystay. In 1996 a 'Solent' stay was added to allow the setting of a battened blade jib or storm jib. This stay is easily removable.


Sunstone is a centerboarder. However, unlike many of the CCA centerboarders, such as Finisterre, she has enough draft and stability to make her stiff and safe in heavy weather. As Olin says in his chapter on design for heavy weather in Heavy Weather Sailing (Adlard Coles, editor Peter Bruce); 'Among S&S designed centerboarders, Sunstone seems a good example of a centerboarder suited to heavy weather sailing.' The unballasted centerboard is of stainless steel. It originally gave a draft of 9'8". For rating reasons under IOR a removable stop was put in to reduce this to 7'2". This reduced weather helm and still gave outstanding windward performance. The top of the rudder originally came level with the waterline. To increase efficiency a fillet piece was added to the top to bring it near the hull, making it more like later S&S rudders. There have been no hull modifications.





Unlike many classic yachts of her age Sunstone has received consistent attention to her fabric and equipment throughout her life. That maintenance and her original robust construction have meant that no extensive rebuilding or refastening has been required.

Sunstone's main saloon (Some details may have changed since this photo)





Though there is a pipe cot in the forecabin, it has always been used only for storage of sails and equipment. Because no refrigeration or cool box was built into the original accommodation, there is a 12v Waeco portable fridge on the floor area of the forecabin; this unit can also operate from mains power through a bulkhead mounted transformer. One of the two house batteries is to port.


Aft of the forecabin to port is the heads with a Raritan marine toilet and a wash basin. There are four lockers and several small shelves. The largest of the lockers is partly taken up by the holding tank. There is room for a larger holding tank if desired.


Opposite the heads were originally two hanging lockers. The doors of these are still in place, but the forward locker is mostly taken up with the chain locker, while the after locker has some hanging space, but also contains the windlass motor.


The main saloon has two settees, the seats of which can be pulled out to make more comfortable berths. Originally there were two pilot berths. The mattress area of these berths has been converted for stowage and mahogany bookshelves have been installed outboard. The stowage and shelves are easily removable if it was wished to restore the berths to their original use by the addition of mattresses. There are large lockers in the settee backs, with water tanks and more lockers beneath the settees. There is also room for significant stowage in the bilge. The diesel heater is against the forward saloon bulkhead. The solid teak table folds neatly around the mast. When unfolded its leg is easily secured to the cabin sole with thumb screws. It has two leaves and seats six.


The floorboards of the cabin sole are solid 3/4" teak and holly.





Aft in the main saloon to port, there is a half-sheet sized chart table with chart stowage beneath . The electrical panel is outboard of the chart table seat. The main hatch is offset to port. This allows for a sink and counter centrally to starboard of the ladder. The engine is under the sink unit. The cooker, counter tops and galley stowage are to starboard. The large, three burner and oven Heritage LPG cooker is original equipment.







The offset hatchway also gives space for a proper aft cabin, which is relatively unusual on a boat of this size and age. This cabin has two large and comfortable quarter berths and a small sink in a counter top, with shelf space for large books or manuals. There are two seats and four large stowage lockers and one drawer. The additional locker beneath the port seat is mostly taken up by one of the house batteries.









The main hatch is covered by a fold-down pramhood. There are two large cockpit lockers and a smaller lazarette locker aft of the cockpit coaming. The radiused deck aft of the wheel and the wide cockpit coaming give a comfortable steering position at the wheel whether standing or seated. The B&G instruments give not only wind, speed and depth information, but also performance information based on the boat's polars and waypoint information from the GPS. There is a manual bilge pump under the deckplate aft of the coaming.


The highly geared Whitlock Cobra steering system gives excellent 'feel' as it has a large wheel and direct mechanical linkage to the rudder with no wire or chain.
