Originally posted by na grohmití View PostMany years ago I took the drawings from that issue and redrew them on double scale. It makes for a great wall decoration.
Oddly while the compartments may have slightly different uses now (in particular on 02 deck) structurally and layout wise, little has changed.
A model of her anchor handling arrangement remains in use as a training aid at NMCI. It was unique at the time, and the design has served the ship well.
It always interests me though that in each drawing, the heli on deck is a Lynx, not a Dauphin.
P31 has in my opinion (and many who served on her) been a fine design of ship. A second in class could only have been an improvement, had it happened. Her retirement is inevitable. My only hope is that her sturdy design finds a new use to a future owner. I believe she is well suited to being converted for use as a survey or research ship, should use as a coastguard vessel not be appropriate or available.
I remember a 3 page folding pull out in Cara,
the lease for 242 was not renewed

Britex also works..
The Bits and pieces the British aircraft industry build for the F35 is all they have left to pin their hopes on. The Sea Harrier FA2 was a far superior aircraft, which could have benefited from further upgrades, as the land based GR9 version did. Indeed after the premature retirement of the FA2 (likened to the conquistadors scuttling their ships when they reached the Aztecs so the crew could not mutiny) the GR9 served adequately aboard ship.For now, everything hangs on implementation of the CoDF report.

Originally posted by Graylion View Postyou just calculated the volume of a block. For a ship you'll need the block coefficient, for simplicity's sake assume .5 so we are talking ~6.3 Gg displacement
Block Coefficient Cb is likely, I hope, closer to .75, especially if the stern is near full width and immersed at operational drafts. the tonnage may be approaching 9000 tonnes. I should have included Cb. The volume given was not of the block but of the amount of water displaced by the ship immersed to 5 meters.It's the volume of water adjusted by the SG of water in which it floats to give displacement.Last edited by ancientmariner; 10 January 2018, 08:56.

Endurance Class: 141 * 21 * 5m, 7.6 Gg. This gives a Cb of .513, So I'd say .5 is a decent approximation.

Originally posted by ancientmariner View PostI concede your principal point. The ship in loaded terms would be close to 8000 tonnes. However the requests for expressions of interest will be around a ship 130 X 20 X 5 meters approx. If the ship has a chance of Home maintenance then it must be no bigger than 140 X 21 X 5.5 as the drydock locally is constrained in beam width of ship. A ship with uplift of 2000 tonnes, properly outfitted for role, and with topline defensive equipments should be more than a toy.
