When recorded in 1924 Chinese junk “da tuo” (“Big Pull”) “Hong Kong Trawler” was the generic name given to large local fishing sailing junks in the waters around Hong Kong, Macau and Southern China with LOA (length overall) 72 – 86 feet (22 – 26.3 m) and beam upto 20 feet (6.4 m). This class includes junks ”xia jiu tuo” (in Cantonese “ha kau tuo”), ”qi bang tuo” (in Cantonese “chat pong tuo”), “zan zeng” or “heng zeng” (in Cantonese “cham chang” or “vang chang”).

Da Tuo is normally a gill-net trawler working fishing grounds where the seabed is smooth, flat sandy and rock free.

Traditionally fishermen are “tan ka” who lived onboard with their families. From October through May, the typhoon off-season, the larger junks would spend 7-10 days at sea at upto 100 nautical miles offshore working in pairs trawling a 250 foot (76 m) net..

HMS SHANNON was a 38-gun Leda-class frigate of the Royal Navy. She was launched in 1806 and served in the Napoleonic Wars and the War of 1812. She won a noteworthy naval victory on 1 June 1813, during the latter conflict, when she captured the American Navy's USS CHESAPEAKE in a singularly bloody battle.
Career
Josiah and Thomas Brindley built SHANNON at Frindsbury in Kent and launched her on 5 May 1806. She spent her first seven years under the command of Captain Philip Broke, who was transferred from DRUID and took command of SHANNON in June that year.
Home waters
SHANNON was quickly put into service. She formed part of a squadron under Commodore Owen that was patrolling off the French port of Boulogne. On 8 October she took part in the bombardment of the town using Congreve rockets.
Her next task was sailing in 1807 with MELEAGER to protect the whale fishery off Greenland. Despite encountering ice on 7 May 1807, they were able to push through, reaching the southern part of Spitsbergen on 17 June. There the two ships surveyed the Bay of Magdalena, at a latitude of 80°N. They eventually reached a latitude of 80° 6' N before the ice stopped them. They then turned westwards and reached the coast of Greenland on 23 July. The island of Shannon is named after the ship. SHANNON spent the early autumn cruising from Shetland. She then left, returning to Yarmouth by the end of September, where she cruised off the Downs. She put into Spithead on 28 September to refit.
By the end of 1807, France had invaded Portugal, and SHANNON joined Sir Samuel Hood's expedition against Madeira. The British took the island without firing a shot. Captain Broke then escorted the transports that had accompanied the fleet back to England, where they arrived on 7 February 1808. SHANNON put into Plymouth before returning to patrolling in the Channel.
On 20 July SHANNON was in company with SURINAM and ÉCLAIR when they captured COMET. Then on 21 August, SHANNON was in company with SURINAM and MARTIAL when they captured ESPOIR.
In November 1808, SHANNON took the French frigate THÉTIS in tow. AMETHYST had shortly before captured THÉTIS, which later entered service as HMS BRUNE.
SHANNON spent 1809 with the Channel Fleet and on 27 January captured the French 14-gun privateer cutter POMMEREUIL Broke sent the prize into Plymouth.
On 1 June 1811, SHANNON returned to Plymouth and was put into the dock where her hull was re-coppered. After this was completed, she sailed for Portsmouth to complete her refitting and resupplying in preparation for being assigned to foreign service.
The American coast
Broke and SHANNON were ordered to sail for North America as tensions between Britain and the United States escalated in the run-up to what would become the War of 1812. SHANNON sailed from Portsmouth and arrived in Halifax on 24 September 1811 after a journey of 45 days.
On 5 July 1812 Broke took command of a squadron consisting of SHANNON, AFRICA, BELVIDERA, AEOLUS and later GUERRIERE. Vice-Admiral Herbert Sawyer then ordered him to carry out a blockade of American ports.
Broke's first success came on 16 July when he captured the 16-gun American brig NAUTILUS s off Sandy Hook. NAUTILUS had been on a cruise from New York.
Later in the evening, the squadron spotted and gave chase to USS CONSTITUTION as she sailed from Chesapeake Bay to New York. The chase lasted some 65 hours, during which both pursued and pursuers had to tow and warp. BELVIDERA eventually managed to come within gunshot of CONSTITUTION on the afternoon of 17 July, but a lucky breeze blew up, and CONSTITUTION's clean bottom allowed her to make good her escape.
SHANNON's next duty was to meet a convoy homebound from Jamaica. An American squadron under Commodore John Rodgers had sailed to intercept it. SHANNON ensured the convoy safely passed the Great Banks, before she returned to the American coast. She put into Halifax on 20 September to take on provisions. Sir John Warren arrived while she was in port, and took up the post of Commander in Chief of the North America and West Indies Station. He then despatched SHANNON with the schooner BREAM to rescue the crew and offload the money being carried by the frigate HMS BARBADOES, which had been wrecked on Sable Island.[4] While carrying out this mission, SHANNON encountered and subsequently captured an enemy privateer schooner, Wily REYNARD on 11 October, that she took back to Halifax with her.
On 31 October, while SHANNON was cruising with TENEDOS, NYMPHE and CURLEW, Broke captured the American privateer brig THORN. THORN was armed with eighteen long 9-pounder guns and had a crew of 140 men. She was three weeks out of Marblehead on her first cruise. Sent to Halifax with a prize crew, THORN was subsequently purchased and renamed as the Nova Scotia privateer brig SIR JOHN SHERBROOKE.
Sir John Warren was at Bermuda during the winter of 1812, and left Broke in command of the Royal Navy squadrons operating on the coasts of Nova Scotia, New Brunswick and New England. In December Broke took the SHANNON and escorted a homebound convoy half way across the Atlantic, returning to North America by sailing round the Azores. In 1813, Captain Oliver arrived on the station aboard the 74-gun third rate VALIANT, and took command from Captain Broke. Broke continued to deploy with his squadron until SHANNON and TENEDOS became separated from them in a gale. They decided to steer for Boston, reaching the port on 2 April. Having observed the activity in the port, they returned to their squadron and reported the presence of the American frigates CONGRESS, PRESIDENT and CONSTITUTION. In their absence, CHESAPEAKE had entered the harbour through the eastern channel.
Captain Capel aboard HOGUE ordered SHANNON and TENEDOS to watch the port from close inshore, while the rest of the squadron cruised in the offing. On 16 May SHANNON and TENEDOS chased a large armed ship under American colours, and forced her to run aground near Cape Ann Town. SHANNON anchored close to the grounded ship and fired a few shots to disperse a number of militiamen who were assembling. Lieutenant George Watt of SHANNON then managed to bring the ship off the shore without loss. She was the French corvette-built privateer INVINCIBLE, of 16 guns, originally named INVINCIBLE NAPOLEON. HMS MUTINE had captured INVINCIBLE NAPOLEON in the Bay of Biscay but the American privateer ALEXANDER had retaken her. A prize crew from SHANNON sailed INVINCIBLE for Halifax but the American privateer TEAZER captured her again and sent her into Portland, Maine.
On 25 March SHANNON took on stores of water and provisions from TENEDOS, which was then detached, with orders to rejoin the SHANNON on 14 June.
Fighting the CHESAPEAKE
Issuing a challenge
During his long period in command of SHANNON, Broke had drilled his crew to an extremely high standard of naval gunnery.
"The weekly routine at sea was for the watch on deck to be exercised at the great guns on Monday and Tuesday forenoons, and in the afternoons the first division of the watch was exercised at small arms. Wednesday and Thursday forenoons saw the watch on deck at the carronades, and in the afternoons the second division of the watch at small...

This stamp shows us a sampan used as a handline fishing vessel, details of a sampan you can find in the index, otherwise I have not any detail on this vessel.

Handline fishing, or handlining, is a fishing technique where a single fishing line is held in the hands. It is not be confused with handfishing. One or more fishing lures or baited hooks are attached to the line. A hook, fishing lure, or a fishing jig and many times a weight and/or a fishing float can be attached to the line. Handlining is among the oldest forms of fishing and is commonly practiced throughout the world today.
The fishing bait can be still fished, trolled or jigged up and down in a series of short movements. Often handling is done close to the bottom of the body of water but can also be done near or on the surface.

Salt Water Handlining
Ocean handlining is often used to catch groundfish and squid but other species are sometimes caught, including pelagic fish. Sea handlining a good way to catch larger oceanic fish.

Freshwater Handlining
Handlining is also used for catching fresh water fish. Panfish, walleyes, and other freshwater game fish can be caught using handlining fishing techniques. Handlining can be practiced from the shore or from a fishing boat. Walleye anglers practice handlining over moderately deep water in a drifting boat. Handlining is also practiced by ice fishing anglers.

Handlining Techniques
A jigging motion can be used to attract fish which are normally caught while trying to strike the lure but they can also be snagged by the hooks as they investigate the jigged lure. The lure can also be fished motionless and the angler feels for the bait to be picked up by a fish and then sets the hook after waiting for the fish to fully take the bait. After a strike occurs the hook is set and then the fish is hauled in and the caught fish is removed.

This two stamps shows us fishing vessel which use longlines to catch fish. Of the two vessels depict I have not any information. Wikipedia has the following on the longline fishing vessels.

LONGLINERS: use one or more long heavy fishing lines with a series of hundreds or even thousands of baited hooks hanging from the main line by means of branch lines called "snoods". Hand operated longlining can be operated from boats of any size. The number of hooks and lines handled depends on the size of vessel, the number of crew, and the level of mechanisation. Large purpose built longliners can be designed for single species fisheries such as tuna. On such larger vessels the bridge is usually placed aft, and the gear is hauled from the bow or from the side with mechanical or hydraulic line haulers. The lines are set over the stern. Automatic or semi-automatic systems are used to bait hooks and shoot and haul lines. These systems include rail rollers, line haulers, hook separators, dehookers and hook cleaners, and storage racks or drums. To avoid incidental catches of seabirds, an outboard setting funnel is used to guide the line from the setting position on the stern down to a depth of one or two metres. Small scale longliners handle the gear by hand. The line is stored into baskets or tubs, perhaps using a hand cranked line drum.

In 1981, Bermuda issued a stamp (SG435) showing a privateer, the "Devonshire" approaching a Spanish ship. In fact the ship was British and had its nationality changed by the designer changing the flag.download/file.php?mode=view&id=16958

The book "In the Eye of All Trade: Bermuda, Bermudians, and the Maritime Atlantic World, 1680-1783" by Michael J Jarvis has a B&W plate of the painting that clearly shows the real flag.download/file.php?mode=view&id=16958

Jarvis also describes (p242)how Devonshire nearly captured a Spanish warship despite its Captain being killed. Under another captain the Devonshire did capture a couple of superior Spanish privateers.
