Displacement
editDisplacement is given as 2620 tons. This vessel is 396 feet (121 m) long and 56 feet (17 m) beam. That's a pretty large ship and 2620 tons seems very low. I checked the length on Google Maps and my measurement is very close. It's not possible to check the other dimensions. Displacement in tons is usually estimated by a formula: Displacement (Tons) = L x B x D x C / 35 where L = length in feet, B = beam, D = depth (i.e., the amount of water it needs to float when loaded), and C = the Block Constant. The Block Constant C is essentially how much it looks like a box: if it is in fact a box shape, C = 1. It's not a box and C is usually in the 0.5 to 0.85 range. Assuming it is 0.5, the most conservative, this calculation comes to 8000 tons, more or less. This looks like a far more realistic number to me for a 120 metre ship.Cross Reference (talk) 01:13, 10 February 2021 (UTC)
- As you say, it's was nonsense as written - it was in the article from early days, and I think 2,620 is probably the ship's NRT, for what that is worth. For the moment, I have replaced that by the more commonly used, and sourced, 4,576 GRT, and will come back to the article in the next few days. Davidships (talk) 02:37, 10 February 2021 (UTC)
