Following contacts with British Waterways we got permission to take Invicta through Standedge tunnel under our own power.

This was part of BW’s trials being carried out to establish the effects of fume build ups in the tunnel. They had been trialling various modern craft with low level exhausts but were now ready for testing a boat with a vintage engine with roof mounted vertical exhaust.

Invicta fitted the bill nicely as so we became the first boat of its type to pass through the tunnel under power.
The intention was that the BW pilot would steer the boat and the owner travel on the electric tug or in the boat cabin under “house arrest” so not to present a safety problem if they came out on the deck.


As the controls were unique to Invicta the BW pilot agreed for Brian to be on the boat to advise and attend to the engine during the trip.
Claire was allow

ed to stay in the cabin but Sue had to take Rufus over the top of the hill as pets are not allowed in the tunnel.

Shortly after setting of it became apparent that it was better that Brian steer to boat and the BW pilot advising the best speed and positioning within the tunnel. By combining or relevant skills we had a pleasurable trip.

Unfortunately we became wedged in the last narrow pinch point just before we reache

d Marsden. After backing up and retrying 3 times and still not getting through we reversed to an adit where the assistant BW man went to summon the control centre.

They advised that the level was 3-1/2 inches b

elow normal and we shouldn’t be having trouble. Brian reckoned it was at least 5 to 6 inches below normal by look

ing at the tide mark on the tunnel wall and the levels observed at lock 32W where Rufus had been playing (see previous blog post).


We returned to the pinch point and tried again but became stuck again. Fred Carter the BW pilot suggested we “legged” Invicta through we agreed that it was th

e action of the propeller that was causing the boat to be lower in the water that if it was being towed or legged.
With the three of us using boat poles and hands on the tunnel roof and walls Invicta edged her way forward as if the obstruction was not there.
Ten minutes later, we emerged at them Marsden portal thus completing the first ever trip by a vintage engined boat.

Brian also went into the history books as being the first private boat owner to steer a boat through the tunnel since 1944 when the canal was abandoned.
As the exhaust pipe was removed which is designed to split the flow of gases to each side

the force of the exhaust hitting the tunnel brought down a lot of shale and debris which covered both of us and the back end of Invicta’s roof and sides.

The tug convoy arrived about an hour later as we travelled much faster than they did.


Brian wrote a full formal and report of the trip and sent it to British Waterways, The Huddersfield Canal Society and

Waterways World

Magazine to record the event and gain publicity for the canal.


For the technically minded the full report is set out in the next blog.
