General

The Challenge 67' Class yachts were designed for The Challenge Business by David Thomas, specifically to race around the world “the wrong way”. The design brief called for exceptionally strong, seaworthy, fast, attractive, modern, steel yachts that were able to sail to windward across the Southern Ocean in relative comfort.

 

Safety was paramount both in terms of structural strength and crew safety. Because of the One Design nature of the race, the design was not influenced or distorted by any rating rule and a sensible displacement was specified. Other important design considerations include, ease of access to the structure, equipment, systems, wiring and fittings for maintenance and inspections both at sea and in harbour. Every piece of equipment had to be robust enough to survive a race around the world with minimum maintenance.

 

Many of the design principles were based on Sir Chay Blyth’s (then unique) experience of sailing around the world single handed against the prevailing winds and currents.

 

Devonport Yachts (DML) were chosen to build the fleet to Bureau Veritas highest notation. The construction method allows relatively simple and cost effective alterations to the interior layout.

Broker's Comments

During her career with Challenge Business and with the Ministry of Defence DISCOVERER has safely sailed many thousands of miles. She is now being offered as is, where is, and prospective purchasers are encouraged to examine the yacht carefully to satisfy themselves as to her structural and operational state. She has a new rig and mainsail, but requires a full inspection of her bilge area to be re-coded to Category 0 as well as communications equipment and a new cooker.

Construction and Fit Out Detail

The yachts were designed to be exceptionally strongly built of steel in order that they could face all that the Southern Ocean might throw at them, with absolute confidence. The hulls are constructed of high tensile steel shell plating over “T” bar longitudinals and angle ring frames. A full depth skeg and ertalite bearings provide support for the steel rudder and good engineering ensures absolute reliability.

 

The entire deck and superstructures are of stainless steel in order to reduce maintenance to a minimum. The stainless steel fuel, water and sullage tanks are provided with good access for cleaning. The International Paint coating systems are the best that current paint technology can provide with the result that on return from the world’s toughest yacht race, the yachts looked as if they had returned from a summer cruise.

 

Above the waterline the hull and deck are lined with approximately 60 mm of sprayed Polyurethane foam to provide thermal and sound insulation. The extensive use of Warerite laminates in the interior fit out, ensure light, bright accommodation, which is easy to maintain and keep clean. Maple hull liners and Afrormosa trim are highlighted by the white bulkheads and provide a warm comfortable feel to the accommodation.

 

Hull Shell Plating & Stringers: British Steel- 50A Steel

Hull & Deck Framing: British Steel- 43A Steel

Deck, Deckhouse, Coamings & Plinths: British Steel- 316 Stainless Steel

Ballast Keel: Cast Iron by Iron Brothers Ltd

Keel Bolts: 16 x 30mm Bolts

Interior: Marine plywood with Warerite laminate surfaces

Interior Trim: Afrormosia and Maple bright work in accommodation, Iroko bright work in sailroom

Non Slip Deck Covering Material: TBS.

 

In 2005/06 it was found that the plating thickness in the hull beneath the waterline on DISCOVERER was unacceptably thin. Accordingly, Berthon removed the interior joinery, shot blasted the whole interior bilge, cut out all areas of thin plating and re-plated these areas. This involved around 70% of the original plating between the aft and forward watertight bulkheads. The steel work was then repainted. The bilges were repainted in 2008 prior to her last circumnavigation.

 

DISCOVERER was purchased from the Challenge Business by the Ministry of Defence and has been used for training purposes up the present. Since this time she has had water tight bulkheads fitted, has had a full repaint & has been routinely maintained to a high standard. She had a new spar, standing and running rigging in 2013 as well as new mainsail.  She has been coded to MCA Category 0.   She is not being sold in class and requires a full inspection before she can be recoded together with new safety and communications equipment.  The Notifying Body will require a full inspection of the bilge beneath the tanks before they can re-code the yacht.   

Rig

Type: Bermudan Cutter

Mast & Spars: Atlantic Spars Ltd, Brixham, Devon

 

These were new in 2013 and are painted in Awlgrip white. At that time the standing and running rigging was also replaced and there are Antal ball bearing cars on the mainsail track.  There are 2 aluminium spinnaker poles

Deck Layout & Equipment

The deck layout was designed to be safe, seaman like, efficient and provide as much protection for the crew as practically possible, even in extreme Southern Ocean conditions. The deck hatches are defended from wave action by plinths. Dorade vents keep the accommodation well ventilated even in extreme conditions.

The aft cockpit is particularly comfortable and the bridgedeck area ideal for corporate entertaining.

 

During their circumnavigation's both Mike Golding and Sam Brewster illustrated that the yachts can be sailed single handed fast, safely and efficiently.

 

The deck equipment was selected for its efficiency, robustness and ease of maintenance. All the equipment used fully justified its selection and remains in good condition.

History of Challenge Yachts

Yachts Challenge Business 21, 22, 23, 24, 26, 27, 28, 29 & 30 were part of the ten strong fleet which raced around the world in the British Steel Challenge in 1992/93. During the autumn of 1995 they underwent a series of detailed surveys and inspections. Whist the yachts and all their systems/equipment were found to be in exceptionally good condition, they underwent a major refit. DISCOVERER was built as CHALLENGE BUSINESS 30.

 

The refit amounted to a virtual rebuild with all the systems and equipment being replaced. This included new plumbing, wiring, engine, generator, batteries, pumps, deck equipment, steering gear, mast, spars, rigging and sails. Exactly the same amount of equipment and components were supplied to the “original yachts” for their refit as for the new yacht build. Shot blasting and repainting further ensured that the yachts were returned to 'as new condition'. As a result it was virtually impossible to identify from which build period each yacht originated. The specification was identical to the newly built yachts, as was their structural and cosmetic condition.  In 2013 she was further refitted with a new rig and full service of all her systems before a further sailing programme was undertaken.

 

Yachts Challenge Business 31 through to 35 were built during 1994/95 and launched, together with the refitted yachts, in April 1996. All the Challenge 67' yachts benefited from the lessons learned in the outstandingly successful British Steel Challenge, with many detailed changes/developments being incorporated during this refit.

 

The Challenge Fleet sailed a combined distance of over two million miles since the proto-type was launched in 1990. The fourteen strong, BT Global Challenge fleet proved to be extremely reliable with identical performance.

Conclusions

The Challenge 67' Class yachts have proven themselves to be outstanding yachts; they are probably the strongest and most seaworthy fleet ever to have raced around the world.

 

The yachts have an almost legendary reputation for their performance in difficult conditions, comfort at sea and confidence inspiring ability. Their strength and ability also makes them ideal for high latitudes and gives almost unique access to many places that are inaccessible by other means.

 

The design lends itself to a wide variety of uses as well as Ocean Racing. The deck layout and accommodation makes the yachts suitable for corporate entertaining, adventure sailing, chartering and private use. The accommodation layout could be economically and quickly changed by virtue of the fact that the bulkheads do not penetrate the cabin soles.

 

The Challenge 67' class yachts quality equipment and sound engineering ensures reliability and low maintenance costs. The frequent and stringent regime of surveys and inspections has illustrated that well built and maintained steel yachts can race around the world at least twice in the World’s toughest yacht race and still remain in Bureau Veritas highest notation. The surveys also show that the yachts are in extremely good condition and ready for further Challenges.
