Wooden ships comments on this Tandem 40
The Tandem 40 is a one off custom yacht designed to the very precise brief of the first owner who required a comfortable cruising yacht for blue water voyages that also had the performance and speeds of a race yacht. The original owner stated that she would drive unusually well upwind in brisk conditions due to her high stability and power, but off the wind the design of her stern sections will allow her to semi-plane in strong breezes.
This yacht has several very distinctive features all designed in for specific reasons. The bow has been cut flat in order to increase the foredeck working space, and the beam is very exaggerated compared to her length in order to maximise the waterline length while allowing for water ballast tanks to be installed at maximum beam for additional righting effect. The incredible flare on the hull, particularly around the midships, will not go un-noted. The underwater shape has been carefully designed with quite a deep forefoot and sharp entry to dampen the slamming and help her slice to windward. Her keel is a tandem ‘wing’ design with two vertical plates joined along the bottom edge by cast iron ballast weight. This keel has been recognised as a superb offshore cruising and racing design, allowing maximum stability and righting effect without dramatically increasing draft, showing off its main benefits in a brisk seaway.
This is a very modern yacht in every respect, except she is constructed in timber as this creates a very strong and lightweight hull and is a cheaper option than carbon fibre. She has flat bow with a large foredeck area, wide side decks going aft to a transom stern with distinct tumblehome.
Built by Farrow and Chambers, Grimsby, in 1995 to a Warwick Collins/Stephen Jones design.
Constructed of epoxy strip planking using mahogany and cedar employing the ‘Speedstrip’ method of jointing. Laminated spruce frames at 2’ centres. Hull is finished in an epoxy cloth sheathing.
Laminated spruce back bone with floors of marine plywood, epoxy bonded to the hull.
External cast iron tandem ballast keel fastened through the back bone with stainless steel keel bolts
Marine plywood deck, epoxy sheathed and finished in non-slip deck paint. Teak toe rail and capping rail.
Teak varnished coachroof coamings with epoxy sheathed plywood coachroof deck, finished in non-slip deck paint. Aluminium framed windows in the coamings.
Self draining cockpit constructed of marine plywood. Bench seats port and starboard with gas locker to starboard. Varnished wooden tiller steering with aluminium stock to GRP rudder blade.
Large spacious foredeck with a vast amount of working space created by the bluff bow. Twin aluminium bow rollers in each corner with two Delta anchors. Electric vertical axis windlass on the centreline with aluminium fairleads and cleats.
Very wide side decks due to the flare in the topsides makes moving about the deck safe and easy. High upstanding toe rail with a scrubbed teak capping rail all round with stainless steel stanchions and guard wires set slightly inboard of the toe rail. Shrouds come to the inboard side of the decks so there is no need to duck around them while moving fore and aft
Low profile coachroof with Lewmar skylight hatches and stainless steel safety rails around the base of the mast for anyone working in that area in rough seas.
Cockpit is set right at the aft end of the boat with no aft deck. Canvas sprayhood with removable cockpit tent provides an extra useable interior space when the weather is poor. Aluminium mooring cleats and fairleads with a stainless steel pushpit.
Masthead bermudan sloop on a deck stepped aluminium Proctor mast with two sets of spreaders.
Slab reefing aluminium boom with 3 reef points, all reefing pennants are led aft to the cockpit. Lazyjacks with a stack pack system to simplify sail handling. Adjustable rod vang.
Harken roller furling genoa. Track across the coachroof to take the self tacking jib when using that sail.
All Harken deck gear with Spinlock jammers.
Stainless steel discontinuous rod rigging, new in 2007. Discontinuous rigging is where there is a separate length of rod between each spreader or mast section. This boat has two spreaders, therefore three mast sections, so has separate pieces of rod rigging each side for the cap shrouds. This is common practice for modern race yachts and performance cruising yachts.
Single cap shroud with twin lowers to stainless steel riggings screws and internal chainplates. All chainplates are fastened through structural bulkheads which are bonded to the hull from the bilge to the deck head, spreading the load from the rigging right through the hull.
Split adjustable standing backstay enables the crew to alter the bend in the mast, optimising performance in upwind and downwind situations.
Twin alloy spinnaker poles.
All working lines run aft so all winch work is done from the safety of the cockpit, with the primary and secondary winches on the coachroof deck at the forward end of the cockpit either side of the entrance hatch.
Pair of primary Harken 52 self tailing 2 speed electric winches with controls on the cockpit thwarts.
Pair of secondary Harken 42 self tailing 2 speed manual winches.

Single stainless steel fuel tank located on the centreline with 136 litre capacity.
Single stainless fresh water tank with 182 litre capacity with electric pressure pump.
The design of the yacht incorporates a wood/epoxy water ballast tank either side of the hull running from the deck head to the cabin sole level with a combined capacity of 909 litres. This can be used for carrying fresh domestic water, or can simply be used as windward ballast tanks to improve the trim and performance of the boat while sailing upwind. 12 volt electric transfer pump to move the water from one side to the other when tacking.
Hot water from and engine calorifier with additional immersion heater for use when connected to shore power.
Companionway with sliding hatch and wash boards from the cockpit with steps down into the saloon.
Quarter cabin to port with a large double berth, standing headroom inside the door and a hanging locker.
Main heads to starboard with Jabsco manual sea toilet. Corian sink unit with hot and cold running water and a shower. Wet room style heads compartment with a sump for the shower drain, pumped out with a 12 volt sump pump.
Galley in aft port corner of the main cabin is laid out in a U-shape. Corian worktops with large amounts of storage behind and below the galley units.

Double corian sink unit with hot and cold pressurised water. Drains overboard.
Large stainless steel lined 12v fridge beneath the worktop
Part of the galley forms the engine box on the centreline with a hinged corian worktop lid. This is a great way to make use of the space available while hiding the engine within the joinery.
Chart area to starboard with aft facing seat and chart desk. Incorporates a large hanging locker, and bookshelf for the essential pilots and almanacs.
Main saloon is spread across the full breadth of the boat with full standing headroom.
Settee to starboard, large ebony saloon table slightly offset to port with L-shaped settee to port around the table.
Drinks cabinet beneath the table with ample storage in lockers behind and beneath the settee berths.
Very practical non slip black rubber floor matting throughout the main cabin sole.
Door to starboard of the mast going through to the forecabin.
Heads to port with Jabsco manual sea toilet, small sink with running water and a shower. Similar shower sump to the aft heads with 12v sump pump
Large sprung double berth in the forecabin with various hanging lockers and storage cupboards.
Access to the anchor locker at the forward end of the berth.
Full standing headroom at the entrance to the forecabin with Lewmar skylight hatch above.
The interior has been designed by someone with experience of being aboard a yacht at sea. Although not finished with lavish amounts of varnished mahogany, it is spacious, practical and comfortable. The galley is large while still allowing the crew to wedge themselves in if necessary. The non slip matting is easy to clean and safe when wet, there are carefully placed hand holds and an abundance of storage lockers, with somewhere to hang wet weather gear near the companionway without having to take it all the way through the main cabin.
