  • Metal Fixings or Trunnels

    Metal Fixings or Trunnels

    You are probably aware that we are using trunnels (wooden pegs and modern glues) on Gamecock rather than metal fixings, but do you know why? There are two good reasons, both relating to the environment.

    Firstly, when cutting curved pieces of timber out of planks there is inevitably a high amount of waste: and Gamecock has a lot of curves! This is particularly distressing when the timber is rare and expensive hardwood. So there is an immediate benefit if we can cut the pegs out of the waste hardwood. The fixture is at least as strong as metal nuts and bolts. In a test on the East Quay the Volunteers had great fun using trunnels when moving their workshop, a large metal container full of tools.

    Secondly, we are expecting the use of trunnels to extend the life of Gamecock beyond 60 years. The April 2024 edition of the American magazine ‘Wooden Boats’ has several articles expounding the benefits of trunnels following the capsize in 2017 of a 25 foot Nordic Folkboat built in 1951. When the craft was recovered it was clear that the metal keelbolts holding the one-ton cast-iron keel had come away and all of the ballast was now on the bed of a Norwegian fiord. Outwardly the keelbolts looked healthy but they had corroded to thin needles because of galvanic action and acidity in the oak.

    Apparently as the metal corrodes it diffuses positive ions in to the water so that only electrons remain in the iron and they react with water and oxygen to produce rust. Stainless steel is less prone to this process but the more resistant forms are significantly more expensive and, off course, do not utilise the waste oak. The other consideration is corrosion of metal fixtures from the acidity released by wet, salty timber. Oak has a high level of acidity but even Douglas Fir, popular with boat-builders, can degrade metals. Our Volunteers spent over a Year extracting deeply embedded and corroded metal fixtures from timbers on Gamecock that we wished to retain.

    When trunnels are used they need to be of a similar density to the wood they are fixing. If the trunnel is too dense then it is likely to split or distort the timber in to which it is being driven: if not dense enough then it is likely to come loose over time. So, in the case of the Gamecock the waste oak is ideal for fixing to the oak frames and fits well with our attempts to protect the environment.

  • Pride in Place

    Pride in Place

    Whitstable Maritime has been awarded a ‘Pride in Place’ Grant in support of the Gamecock’s restoration.   

    Canterbury City Council (CCC) is the local lead authority for the UK Shared Prosperity Fund which is a central pillar of the UK government’s Levelling Up agenda and provides £2.6 billion of funding for local investment by March 2025.  The Fund aims to improve pride in place and increase life changes across the UK investing in communities and places, supporting local business, and people and skills.  For more information, visit https://www.gov.uk/government/publications/uk-shared-prosperity-fund-prospectus

    Whilst the fundamental restoration work has been completed, funding is now required for the next stage of Gamecock’s restoration journey:

    • restoring deck-beams and replacing the hull planking;
    • production and strength testing of trunnels (tree nails);
    • developing the Maritime Curriculum including a training programme tailored to the Oyster Yawl;
    • developing educational activities focused on the coast, eg marine conservation, local ecology, oysters and mans impact on the environment.

    The first part of the first plank fitted.

    You can see the amount of twist in the plank. This meant it had to be steamed. Steaming makes the wood go ‘rubbery’ temporarily. It is then clamped into position and as it cools it hardens up again in the new shape.

    Watch this space for more planks being fitted…

  • Dredging for Cockles

    The cockle boats are easy to spot in the Harbour because they are painted a distinctive blue and carry a large hoover on deck that runs the length of the craft. They are here because the Thames Estuary sustains some of the largest populations of common cockles (Cerastoderma edule) in the UK. Reports that the Thames fishery is one of the oldest and most important in Europe with a total of 2560 tonnes of cockles being landed in Kent in 2022, worth over £1.75 million.

    The cockle enjoys clean sand, muddy-sand, mud and muddy-gravel as found in tidal estuaries because they are a shallow burrowing bivalve. They live within the top 5cm of the surface of the mud so they can reach the overlying water for feeding and respiration. Cockles are active suspension feeders using a siphon tube to hold the food suspended in the water column. The shell reaches a maximum length of 5cm. The outer shell is off-white, yellowish, or brown.

    Most cockles live for 2-4 years, but some individuals have been found to be over 10 years old. The cockle’s predators are brown shrimp, shore crabs, starfish, snails, worms, flatfish species and a variety of wading birds such as oystercatchers and knots. Cockles mature after 2 years, spawning in the summer when individuals can produce 200,000 to 700,000 eggs per animal. Cockle larvae are planktonic and spend 3-5 weeks floating in the sea before they metamorphosise and settle on the seabed between May and September.

    The Thames cockle fishery is the only Marine Stewardship Council (MSC) certified fishery in Kent. The fishery is limited to what they can catch during specific months of the year and can only harvest cockles of a minimum size and quantity. This makes sure the shellfish have time to reach maturity and reproduce which is a key part of fishing sustainably. It also factors in the needs of estuary wildlife such as wading birds that overwinter on the tidal banks and feed on the cockles.

    The large pipe on deck is the Hydraulic Suction Dredge used to capture the cockles. This is one of the few methods allowed to harvest cockles and is the most efficient. The Kent boats fish by towing the hydraulic dredge along the seabed at speeds between 2 and 6 knots. The blade on the dredge is set to penetrate a minimum depth of 5cm. and the minimum landing size is 16mm. The fishing season runs from July to October.

  • Size Matters

    The typical Whitstable Oyster Yawl was between 40 and 45 foot in length. There were exceptions, for example the Rosa & ADA (F105) was 47 foot and Thyra was only 36 foot. For the yards along Island Way these were relatively small. Much larger craft were built on the slipways and then let down in to the sea at a time when there was no sea-wall.

    If you are interested in learning more about the larger vessels, then the Merchant Ships of Whitstable by Wallace Harvey (Emprint Publications, 1993) is a good source.

  • Stormy Petrel

    Stormy Petrel (F71) was built in Whitstable as an Oyster Smack/Yawl in 1890 by Richard and Charles on Island Wall. She was owned and fished by her builders, dredging oysters in the summer and used for stow-boating in the winter. This continued until 1928 when she became a watch-boat for the Seasalter and Ham Company, moored at Pollard Spit overlooking their interests in the oyster fishery east of the Isle of Sheppey.

    After World War Two, Stormy Petrel was sold to a barge and smack skipper, and author, Bob Roberts of Harwich. He subsequently sold her to Bernard Rozier, his third hand. In 1962 she was bought by Dick Norris on the Medway and in 1998 he began a refit lasting 3 years. Then in  2018 she was sold to Luke Powell (who trained as a Shipwright in Faversham) and she is now based on the Fal Estuary in Cornwall.

  • Volunteer of the Year 2023

    Volunteer of the Year 2023

    At the recent Whitstable Boatyard Reception, the Charity was pleased to present Peter Kalopsidiotis with a gift in recognition of his contribution as a Volunteer to the restoration of the Gamecock. The Charity has also proposed to National Historic Ships that Peter should receive the National Volunteer of the Year Award. The citation read as follows. Peter joined Whitstable Maritime’s restoration team in 2019 when the Gamecock was lying on a mud berth in Faversham Creek where she stayed throughout the pandemic. It quickly became apparent that he was keen to learn new skills and was soon leading the small group that kept her dry and protected the craft when the wind and high tides threatened to drive her ashore.

    In 2020 the Charity persuaded Whitstable Harbour Board to allow the Gamecock’s restoration to continue on the East Quay of the harbour. Peter organised a successful tow (photo) from the top of Faversham Creek which involved judging the tides in Faversham and Whitstable.

    Once installed on the Quay, under the direction of our new Shipwright, Peter’s team of Volunteers set about removing the rotten timbers and fittings (photo). He forged a good relationship with the Shipwright and it has become an effective partnership with Peter helping to establish a small boatyard and workshop extending to neighbouring premises provided by Brett Aggregates (photo). Peter’s ‘hands-on’ approach involves him being at the site several times a week.

    Peter has joined the Board of Whistable Maritime as the Vice-Chair responsible for the restoration project and actively participates in the purchase of materials with the Shipwright, including visits to the local sawmills who now source our oak, larch and pine. Currently they are stress-testing trunnels and researching sails and rigging. 

    Clearly, many have contributed to the restoration and continue to do so, but Peter has become a key Volunteer in the process and hopefully will become a member of the crew when Gamecock returns to the water in 2025.

  • Money, Yawls & Oysters

    Gamecock is one of the finest examples of her type, but why build a boat dedicated to a single purpose – the dredging of oysters? The answer is money.

    Gamecock is a graceful boat with curved lines running from bow to stern but her design is very functional. The hull is lacking in space because she rarely worked overnight. Her single keel was protected by a metal gutter to avoid damage on the hard sea bed. Most of the work was undertaken on the deck so it was extended to the rear by a counter-stern. Her design was the result of her function and working environment.

    Gamecock was not built until 1906/7 when there were still over 70 Whitstable Oyster Yawls in the fleet. In 1862/63 The Company of Free Fishers and Dredgers of Whitstable sent 60 million oysters to market at a value today of £91,000, equivalent to £11.5 million today. Not every year was as bountiful but Allan Collard, writing just before Gamecock was built, reckoned that the Whitstable Company annually sent 10 to 15 million oysters to market: (quoted by Derek Coombe in Fishermen from the Kentish Shore, published by Meresborough Books 1989).

    With such a precious product lying on the sea bed there was more than one company interested in dredging the Swale, not to mention possible poachers. The main competitors were The Faversham Oyster Co, The Ham & Sea Salter Co, and The Whitstable Oyster Company. To mark their respective territories the oystermen agreed ‘transit lines’. David Roberts, Chair of Whitstable Improvement Trust, has recently researched these navigation aids which he explains as follows.

    The old iron post, now leaning over, situated at the end of Island Wall, on the edge of the Village Green at Saxon Shore, has been in this position since its installation in 1865. It can be safely assumed that there was a marker beacon of some kind in this location long before this date.

    This post functioned as the front marker (landmark) which could be lined up, by fishermen out at sea, with a back marker called the “Cross” (removed in the 1960’s) situated on higher ground just beyond the railway foot bridge at the end of West Cliff.  This line, called a transit line, defined the boundary between the beds owned by the Company of Free Fishers and Dredgers of Whitstable and the Seasalter Oyster Fishery Company.

    The Whitstable Improvement Trust assisted by Canterbury City Council, The Whitstable Oyster Company, The Whitstable Museum and Timescapes Kent considered it important to bring the existence of the last surviving oyster bed boundary marker to the attention of the public by recently making it more visible and installing two information boards to explain its significance. 

    It was one thing to mark out the territory, it was another to police it, especially at night. So the oyster companies employed ‘watchboats’ to guard their oyster beds. These were usually vessels too old for work and the crew were paid a bonus for being on duty overnight or at weekends.
