Mozambique’s Navy gets $550,000 boost Mozambique’s Navy is being boosted by donations of vessels worth some $550,000 from Washington. Three patrol boats worth $140,000 were donated and handed over at a ceremony in Maputo. They will be used forcoastal patrols and humanitarian relief operations. The US chargé d’affaires, Mr Daniel Johnson, said a separate donation of eight or nineboats worth $400,000 would be made shortly.Mozambique’s new naval commander, Admiral Patricio Yotamo, refused to give reporters any information on the number ofpersonnel and vessels he had under his command. The 200 men operate two South African-built Namacurra class inshore patrol boats and some motor boats on Lake Malawi.
South African inflatable boat manufacturer Mako Marine has concluded the delivery of a number of inflatable boats to the Armed Forces of Mozambique (FADM).Mozambique's President and Commander-in-Chief Filipe Nyusi on 15 February inspected the newly delivered Mako Defender 470 boats, which were acquired to replace old and damaged boats. The Mako 470 is a fully inflatable model with a rigid aluminium floor and Hypalon (hydrocarbon resistant material) pontoons, reinforced for military use. It is powered by a 50 hp Yamaha outboard engine, which was selected due to its simplicity, ease of maintenance and ready availability of parts.During his tour, Nyusi visited the Marine Corps Barracks, Artillery Practical School and Maputo Naval Base. He inspected the more than half a dozen Mako boats that were recently delivered to the Forças Armadas de Defesa de Moçambique, along with crew training. This took place from 14 to 17 February at Catembe Military Base outside Maputo and saw eighteen people attend the course.[continua]

a trimaran offers greater stability, higher speed, better fuel efficiency, a shallower draft, more deck space, smoother seakeeping, and damage tolerance compared to a traditional ship, but it also comes with drawbacks such as more complex construction, higher costs, structural stress on the hull connections, greater maintenance needs, port limitations due to its wide beam, and reduced maneuverability.
A couple more tradeoffs worth mentioning: hull volume, and its corollary - capacity - and excessive stability.Compared to a monohull that either uses equal weight of materials or is of similar dimensions, a multi-hulled vessel has less internal volume as an inevitable consequence of having a big hollow space between the hulls. Combined with the more complex construction, that also makes them less cost-effective except in cases where high sustained speed is required. Which is why cargo ships are almost universally monohull, as are most blue-water warships.There is also very much a thing as being too stable. A ship with high stability has a very fast roll period; essentially the time it takes to do the full back-and-forth motion of a roll, then recover to neutral from it. Which is good for staying afloat, yes, but a snappy roll also means the motion of righting is more violent, leading to greater seasickness, and throwing of personnel around, to the point where they might be incapacitated. A good example of this is the Spearhead-class EPF, which has speed restrictions in higher sea states not because the hull can’t take it, but because everyone would be too busy puking their guts out to man their stations - in the same vein, this is why Independence uses a hybrid trimaran hull with a standard bow.

Em pdf por enquanto, agora a Marinha vai ter tanto dinheiro que até vai conseguir fazer a manutenção aos seus navios... talvez.
