Dover Harbour Board's Pilot and Harbour Patrol launch, DHB Dovorian, moored to the Marina Reception Pontoon against the Crosswall Quay of Dover's Tidal Harbour and Marina at low tide, 6.58 am on Tuesday, the 19th of April, 2011.

The short tunnel to the non-tidal Granville Dock behind the Dovorian was probaly a sluice gate but has now been bricked off.

By the by:

There's a similar but much longer tunnel leading from the Tidal Harbour to the non-tidal Wellington Dock, out-of-shot to the right. Having come prepared wearing wellingtons, I went down this tunnel after taking the above photo because I had noticed the day before that the original sluice gate still seems to be in place (I could see water gushing in from the top and sides at the far end).

This was just a recce and none of the photos I took were particularly good, although I know what to do next time (I think). Anyway, while I was paddling about, and getting incresaingly nervous about water bubbling up through a crack in the floor a few yards from the tunnel-end, I forgot that everything I touched and brushed against spent a great deal of its time completely submerged. When I got home I was astonished to find I had cycled through town looking like The Thing from the Swamp!

Back to business:

Out-of-shot to the left is the RNLB 17-09 City of London II lifeboat (below the Lifeboat Station) and P275 HMS Raider, a P2000 "Archer Class" Fast Training Boat.

P275 HMS Raider, along with P165 HMS Example (ex-A153 XSV Example) and P164 HMS Explorer (ex-A154 XSV Explorer) arrived in Dover Harbour on Monday, 18th of April, on an overnight visit.

DHB Dovorian was christened by the wife of Robert Dibble, the then Chairman of Dover Harbour Board (now Roger Mountford), on the 11th of October, 2006, joining DHB Director (at least, I think that's her name!) in performing the dual roles of harbour patrol and pilot service.

The twin-screw and twin-rudder Dovorian was built by Goodchild Marine Services Ltd of Burgh Castle, Norfolk, who announced in February, 2011, that they are to build a similar harbour patrol vessel for the port of Calais in France.

Also (1):

Dovorian is a well appointed launch, fitted out to a high standard. A portside helmsman position was chosen and the controls fall easily to hand. In addition to the engine and gearbox controls and instrumentation the boat is equipped with a Simrad CA44CRT radar with a 10inch display and Simrad GPS. The magnetic compass is a Plastimo Offshore 135 instrument and Raymarine supplied an ST 60 speed log and depth sounder. Radio communication is provided by an Icom IC-M601 DSC waterproof VHF set and an ICOM IC-M1 Euro V waterproof handset. (1)_

The hull and superstructure is moulded in accordance with Lloyds Register of Shipping SSC rules appropriate to Pilot Vessels and complies with the requirements of the MCA Harmonized Workboat Code of Practice for Pilot Vessels - category 3 (1)_

The one-piece Glass Reinforced Plastic (GRP) hull was built by Aquastar of Guernsey (Channel Islands) and based on their Aquastar Nelson 42 hull.

Of historical interest (3):

Pilots in the Cinque Ports were originally high-status seamen who were vital to the Channel passage trade, being hired to conduct ships through the dangerous Dover Straits, to the ports of Holland, Flanders and France, and to the entrances to the Rivers Thames and Medway.

The Dover Pilots formed a fellowship or association, supervised by the Court of Lodemanage (held in Old St James Church), which set itself up with regulations and officers in 1526 partly in order to keep the work to themselves and also to fend off foreign competition. They took turns in piloting ships and were required to be constantly at sea in readiness for incoming and outgoing ships who needed their services.

...In 1988, due to improved radar, communications and traffic control, the Cinque Port Pilots were disbanded and local pilotage passed to harbour and river authorities.

When in range of AIS, the vessel's current position is shown at:

DHB Dovorian Pilot and Harbour Patrol Launch

The Automatic Identification System (AIS) is an automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships and AIS Base stations. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.
