Kings Easton displacement figures

[Rhapsode]

Can anyone tell me why the Nic 36 has a displacement of 7640 Kg – 426 Kg more than the Nic 38’s 7214 Kg. and why the Nic 39 at 10,550 is 3286 Kg more than the Nic 38?

Seems odd at first glance that the smaller boat has a bigger displacement than the 38 and that the 39’s displacement is a massive 3 tonnes more.

I am posting this response for Jeremy Lines, who is retired C&N, but was a principal involved with the Nic 38 builds.

Our displacement figures were normally shown as Half Load Condition which was with all normal cruising gear aboard, tanks half full, a small amount of stores but with no people or personal gear. The Nicholson 36 was shown as 7.52 tons with 3.15 tons of lead. The 38 as 7.1 tons with 2.65 tons of lead. The 36 had a heavy construction with a complete wood framed deck as compared to the 38’s GRP deck. The 36 had a much taller rig and was for racing whereas the 38 was for cruising with much more form stability. The 38’s attracted much more cruising gear so there will be few 38’s under 8 tons. Their sinkage will be 0.39 tons per inch. The 39 is a much larger yacht, over 3′ longer on the WL and a foot more beam. Displacement increases as the cube of the dimensions.

Thanks Marilyn and Jeremy, all clear now.
