HMT Gulland and the Loss of Arab Trader off Mombasa
HMT Gulland was an Isles-class trawler built for the Royal Navy during the Second World War. Designed for anti-submarine patrol and other naval duties, the vessel was sold to civilian owners after the war and eventually lost off the coast of Kenya in 1951.
Wartime Service and Design
The Isles-class trawlers were working vessels adapted for military use, measuring 164 feet in length with a beam of 27 feet 8 inches. Displacing 545 long tons at normal load, they were powered by a single triple-expansion steam engine fed by a cylindrical boiler, capable of reaching 12.25 knots. Each ship carried a crew of 35 to 40 officers and ratings, along with up to 183 long tons of coal for fuel.
Gulland was one of several trawlers converted for Royal Navy service during the war years, when fishing vessels and similar craft were pressed into military roles. The class proved useful for patrol work and other duties that did not require the speed or firepower of purpose-built warships.
Postwar Changes and the Final Voyage
After the war ended, Gulland was placed on the disposal list and sold to Belgian owners in March 1946. The ship changed hands again the following year and was renamed Henken. Two years later, she was sold to Arab Navigation and Transport Company in Aden and renamed Arab Trader.
On 13 April 1951, Arab Trader grounded three miles north of Mombasa while sailing from Aden to Mauritius with a cargo of lentils. Heavy seas soon flooded the engine and boiler room, and the wreck settled on the reef with the main deck awash at high water. With no salvage capability available in Mombasa and the cargo rendered worthless by seawater, the ship was abandoned as a total loss.
Wreck and Rediscovery
The vessel broke up in the surf following the grounding. The remains were later demolished with explosives, leaving little visible trace of the ship. In the 1970s, during an extremely low tide, wreck material was rediscovered in front of the Reef Hotel, consisting of scattered steel plate and machinery on the edge of the reef.
Understanding Trawler Conversions
Fishing trawlers like Gulland were valuable to navies during wartime because they combined shallow draft, reasonable cargo capacity and manoeuvrability in confined waters. Triple-expansion steam engines were the standard propulsion for merchant and naval vessels of this era, using three cylinders of increasing size to extract maximum efficiency from steam pressure. Indicated horsepower measured the theoretical power output of the engine based on steam pressure and cylinder dimensions, while actual speed depended on hull design and load. Deep load draught referred to the depth of water the ship displaced when fully laden with cargo and fuel, affecting where it could safely navigate.
