Kenia issued in 1989 a set of five stamps which show monuments in Kenia of which two stamps depict a dhow see: viewtopic.php?f=2&t=12908&p=14118&hilit=dhow+Kenia#p14118

The 3s40 shows also a pillar placed by Vasco da Gama’s crew in Malindi of which I found on the internet:
The pillar is one of the oldest remaining symbolic Portuguese monuments in Africa. Built in 1499 by Vasco Da Gama, the great Portuguese explorer, the pillar was a sign of appreciation for the welcome he received from the Sultan of Malindi. Da Gama was said to build this pillar everywhere he visited. The cross sign on the pillar was tested and found to be made of Lisbon limestone, proving that it is the original cross, placed at Malindi in 1499.
According to recorded history, it was in July 1497 that Vasco Da Gama, with a fleet of four vessels the SAO GABRIEL, SAO RAFAEL, BETRIO and a 200 Ton store ship sailed from Lisbon, Portugal. He had three interpreters – 2 Arabs and one speaker of several languages. On April 7th, the expedition reached Mombasa and on the 13th anchored at Malindi where he established amicable relations with the Sheikh of Malindi, Ahmed Bin Majid. On 20th May, 1498 Da Gama returned to Calcutta India after 23 days at sea.
On his return voyage the fleet made again a call at Malindi, were he arrived on the 07 January 1499, after a passage of 132 days and many of his crew died of scurvy at sea. Da Gama decided to burn down SAO RAFAEL. As a mark of discovery, he created a Padro (Pillar) at the Sheikh’s house made of Libson limestone and bearing the Portugal coat of arms.
In view of the Odium, it was removed and re-erected. When Malindi became Portuguese Northern Headquarters in 1512, the Padro was not mentioned by the Portuguese travelers in mid-16th century. It may have fallen down and then re-erected again with its cone shaped support before the Portuguese moved to Fort Jesus, Mombasa in 1593.

The fishing junk used in the Thua-Thien-Hua Province area and mostly seen in large groups in the cities of Hue and Quang Tri or sometimes on the rivers and inland waterways.

She are constructed from 5 poorly squared and loosely fitted yellowish-brown hardwood planks, which are literally sewn together. Not any frames are installed. She are widely seen on inland water ways and rivers but rarely seen on the open sea, she are not seaworthy.
She are rigged for one or two lug sails and mostly used for fishing, but also used as a cargo carrier, houseboat or ferry. The type has a long bowline and prominently raised stern. The type is seen also without sails and powered by long sweeps or poles.
Now mostly motorized by a small 6hp engine. The vibration of the engine gives a lot of problems with the water tightness of the hull.
Some thwarts installed are supporting the cabin top and are secured with long iron spikes. The water-tightness is put on the inside of the hull and can easily repaired without hauling the boat on shore.
An outboard rudder is fitted which extend below the hull, and can easily re-moved when in shallow waters, a sweep is then used as rudder. She has not an anchor and are moored to bamboo poles.
Has a bamboo shelter of 8 feet which is made of woven bamboo strips, sealed with vegetable oil. Sometimes more shelters are made, and when fishing or carry cargo the shelters are stacked upon one cabin, or left on the beach.
When fishing she leave port before sunrise and returning before sunset. The junk is not fitted out with any navigation lights (1962).
Fishing is done by a trawl net astern or between two junks.
The junk is now more often used as a family home and some junks have been seen with a family up to 10 persons, which are farming or doing other work ashore.
Building time is about two to three weeks and cost around US$ 100 in 1962.

Dim. length 6.83 – 14.08m, beam 1.04 – 1.98m, draught maximum 0.49m

The junk depict on the 20d stamp of the Da Nang area is a traditional Vietnamese boat, the origin of the type is obscure, and the boats have a woven bamboo bottom sealed with resins. Otherwise wooden planking is used. Others are built with a complete wooden hull.

The bamboo bottom is very resilience against the shock of beaching the vessel, the bamboo bottom has been regular replaced at least every 5 years, but is not expensive, bamboo is plentiful, and the crew can do it herself. Most of this boats are built by the owners and she are built in a small clearing near the beach. The building tools are very primitive and have been used for centuries. The junks are constructed from green lumber, crack will soon appear in the wood and seams opened. The frames are added last. The bamboo bottom is pressed into the upper hull.
She are designed as a fishing junk but can also carry cargo, when fishing is not possible due to the weather.
Fishing is done mostly with pair junks which tow astern a purse type net or a smaller circular net
Most are day fishers sailing from the port around 21.00 to 05.00 in the morning and returning between 15.00 and 19.00 where the fresh fish is discharged at the fish market.
The type of junk is tender and during heavier breeze conditions she heels dangerously and a hiking strap or board has to be used by the crew.
Nowadays she are more motorized.
The type when sailing has from 1 to three mast with a yard and boom, when the sails are not used the crew roll the sail around the boom. The yard and boom are mostly made of bamboo, the sails are mostly made of finely woven palm fibre, which have a short lifespan, but she are not inexpensive and light. When leaving port or entering sweeps are used.
The smaller type is open while the larger ones are fitted out with shelter cabins which are made of woven bamboo lath sealed and coated the same way as the basket bottom. Sometimes the junk has up to three cabins. When fishing this cabins are stacked together to give more working space to the crew.
When a family own the boat and live on board one cabin frame is attached to the gunwale, living accommodation is very simple with only straw mats as bunks. Others the crew is living ashore with their family.
In the 60s most of this junk were not fitted out with navigation lights and only carried a bamboo flare to indicate the position.
These junks often have a round basket boat on board for tending the net, not any lifesaving equipment or spare parts are carried on board in the 60s.
When she are fitted out with a diesel engine in the basket bottom junks, it is supported by thwartship members which in turn are secured to the more sturdy side planks of the frames.
The engine power is 5 – 20 hp.
For maintenance the junk is beached and sailing rig removed after she is capsized and the hull can be cleaned and re-caulked and re-coated with vegetable oil, when she is fitted out with a bamboo bottom the inside and outside are brushed with a bamboo brush where after she is resealed with compound made of ground bamboo and resin, then recoated with vegetable oil.

Dimensions: length 4.88 – 9.14m, beam 1.01 – 2.29m.
Crew 3 – 6.

In the XIV-XVI centuries in the composition of combat squadrons and detachments of ships sent to geographic expeditions, specifically included small deck sailing-rowing vessels - frigates, which served messengers of high-speed ships. The sailing rig of such frigates consisted of two oblique Latin sails. The displacement reached 60 - 80 tons. Crew-12-15 people. Usually, when a combat frigate or research vessels follows a squadron of squadrons, the messenger frigate was towed by one of them.

GHE GIA: A fishing vessel used in the province Quang-Tri, Vietnam, she is small boat, which mostly sails in large fleets while fishing with a drifting net.
She are very seaworthy in often very rough seas on this coast.
Built with a narrow beam, and the use of a hiking board https://en.wikipedia.org/wiki/Hiking_(sailing) made this crafts almost uncapsizable.
The floor timbers are in flat sections on the bottom and angled on the bilges. The futtocks are canted to match the body plan of the planking.
The fastening of the planks of the hull are with iron boat spikes.

This first appears north of the Col de Nuages. The planks are fastened through their edges by the use of large spikes driven laterally into triangular notches and holes drilled with a bow drill, all on the interior of the vessel. Everything is then puttied.

The rig has two sails in “la buon” with a very long yard and boom spread them on the relatively short masts. The boom and the yard, of the same dimensions, are both seven meters long, for a height of at least five meters on the main mast.
The advantage of these sails is that they are easy to brace in order to obtain a large leeway surface necessary for drift net fishing.
The use of bowlines (ed note: to control the leading edge of the sail) is constant, and the hiking board is run out to windward, at the slightest breeze.
The masts can be raked fore or aft and the shrouds are set up with large wooden thimbles and lanyards to holes bored through the frame heads.
Let us mention that this boat, during fresh breezes, uses a stay rigged to the stem at the very end of the vessel. Because of the length of the sail, the yard takes on a rounded shape, very typical.
The lack of centreboard and the slender shapes of the boat indicate that this craft can only sail before the wind.
