More details of the trunnell boat or Poole canoe

Thanks to John Button I now have a bit more information about one type of the low-powered Poole canoe motor boat otherwise known as a trunnell boat – a 20-footer.

Clicking on the image above will take you to the Save Old Seagulls website new page – to find the pdf you’ll need to scroll down some way.

John says 15hp that generally enough to make these boats perform very well even when laden with fishing gear – and adds regretfully that there’s not much left to catch in Poole Harbour these days.

Myself, I’d have guessed a rather smaller power plant would deliver pretty adequate performance most of the time, but as always I’m always open to being corrected.

John says the boats are sometimes called floorboard boats by the locals because that’s what they’re made of. Some of them will be in action between midday and 3pm this Saturday as part of the town’s piractical celebration Harry Paye Day – if it doesn’t get rained and blown into oblivion. For details see the organiser’s website.

Thanks John!

Here’s an earlier post about Poole canoes.


Poole canoes – the motorised flat-bottomed skiffs of Poole Harbour

Poole canoes, photographed by John Lockwood

Home Built Boat Rally UK (HBBR) member John Lockwood has sent me these photos of a British Isles flattie I hadn’t known about until recently: the oddly-named Poole canoe.

The British Isles aren’t generally thought of as the home of flat-bottomed boats, and I can’t tell you how often I have told me that a flat-bottomed boat can’t work. And yet, there are quite a few around our inland waters and even on our coasts, including the turf boats and flatners of Somerset, the punts of the Rivers Thames and Cam, various gun punts, the Fleet trow and the Wexford cot. And, of course, going up-scale a range of lighters and coastal barge types including the celebrated Thames barge have flat bottoms.

So I was pleased a few weeks ago to learn of the Poole canoe a few weeks ago, and I’m now grateful to John for capturing these slender flattie skiffs with his camera before the original wooden boats disappear. I have the impression that they range up to around 22ft by 4ft or a little over. Thanks for the informative shots John!

A message from ‘Tranona’ on the PBO forum suggests that the boats built in the area for use in Poole Harbour were built by eye – and that British Seagull proprieter Mr Weyhope spent years experimenting to get the best speed out of the boats driven by a Seagull 102 model, which I’d guess was a 2hp type. Looking at the boats in these pictures, they mostly have the small amount of rocker I would expect for a low powered boat, though one or two seem to have rather flatter runs, which would suggest they were intended for a bigger power plant.

In this connection, some weeks ago I put up a post linking to an online ad in which someone was selling an old Seagull outboard still in its original packaging, and accompanied by a set of drawings for building a flat-bottomed skiff, which I suppose is likely to be one of Mr Weyhope’s designs. I’ve posted a tiny thumbnail of the drawings at the bottom of this post, and although it only affords a little information there seems little doubt that the ‘20ft trunnel boat‘ it presents is a Poole canoe, or something very like it.

I must say that I’m particularly interested in these boats at the moment, as they are so similar to a design project I’ve been working on for a friend for some time, and I can’t help feeling that they’re a kind of endorsement of the basic idea.

My project is a little different – my ‘client’ wanted a flat-bottomed design he could build in his garage and that would work with a 4-5hp motor rather than Mr Weyhope’s 2hp model – but the drawings I made before I’d even heard of the Poole canoe seem very like the South Coast boats. See my initial drawings here.

I plan to complete them as soon as I can decide whether the end of the prop should be inside or outside the transom when raised – I notice that the long wells seen in most of these photos imply that the prop is inside the well when the motor is raised – and yet I wouldn’t want to find a flailing prop in my well after hitting an underwater obstruction. Does anyone have any insights on this question?

By the way, I gather GRP Poole canoes are still made for fishermen by Salterns and that the yard has developed a higher powered 22ft model designed for sun bathing, fishing and exploring Poole Harbour, and powered by a 30hp electric start outboard. It even comes with a sun deck, picnic table, cool box, navigation lights, fishing rod holders, a tray in the stern for ring netting and flush decks. All of that seems a long way from the boats in the photos!

Thanks for the shots John!

Worm in old Poole Harbour carving threatens UK wood jetties, archaeology and boats

Merman carving found in Poole Harbour contains warm water ship worm

decent royalty-free images of the blacktip shipworm – please
point us to any you know!

An old carving found off Poole Harbour by Bournemouth University archaeologists has been attacked by a warm-water ship worm that could threaten boats, archaeological sites and wooden structures around the UK.

The carving of a merman in the Swash Channel near the entrance to the Harbour is said to be an important find, but the discovery of the warm-water ship worm Lyrodus pedicellatus or blacktip shipworm in both the carving and in timbers of the wreck could be rather more significant.

‘The presence of this type of borer can be interpreted as an indication of global warming, as it typically lives in more temperate waters, such as the Mediterranean,’ said one of the academics, Paulo Palma.

‘If this species of ship worm continues to spread at its current pace it poses a major threat to all submerged wooden structures around the British coast including jetties and piers, as well as to our underwater heritage.’

It seems pretty sure that this creature eats wood, it’ll attack many of our most important old boats too.

Undergraduate marine archaeology students from BU have spent the last three summers mapping the Swash Channel wreck which emerged in 2004 following dredging work. The wreck is believed to date from the early 1600s, although its exact country of origin remains unknown.
