Two ofthe boats have already sailed torVenezuela and the remaining fourare at various stages of fitting outand trials.The FPBs were designed by VosperThornycrott to meet the specificrequirements of the VenezuelanNavy. The contract for their designand construction was placed inApril. 1972. and valued at over £6million.The 37 metre boats have steelhulls driven by two diesel engines atspeeds of up to 30 knots. Three ofthe six carry a gun armamentconsisting of a 76mm Oto Melaragun mounting with associatedNuova San Giorgio NA 10 fire controlsystem and smaller weapons, whilethe remaining three are to carry atwin Otomat anti-ship missile systemand 40mm gun.The 76mm Oto Melara gun isa fully automatic weapon capableof rates of fire from single shots upto 85 rounds a minute. It is a veryaccurate, well tried gun,comparatively light in weight andvery suitable for the larger types offast patrol boat. It has a range ofover 16.000 metres. Where used inconjunction with ELSAG fire controlequipment, as in these boats, it iseffective against missiles, aircraft orships and can also be used forbombardment.When the mounting is ready to fireand switched to remote control thefirst 80 rounds can be fired with thegun completely unmanned, afterwhich it is only necessary to reloadthe revolving magazine. Thecomplement of each boat is Captain.three officers, four petty officers andten ratings, with spare accommodationfor two more.The hull design is a development ofearlier Vosper Thomycroft steel FF*Bforms, having modified round-bilgesections, a spray-deflecting knucklein the tops ides forward, and a spraystrake between this and thewaterline. the afterbody has a firmrounded bilge and deadrise reducingto about 3 degrees, straight buttocklines and a substantial skegThe aim has been a good reserve ofbuoyancy forward, deflection ofspray and solid water, and goodrunning characteristics at speedand in following seas. Thesecharacteristics have beenconfirmed on trials.The hull structure is of wektodsteel, on the longitudinal systemwith deep framing and longitudinalgirders and stringers.
