Boats don't have a high density. It has to be lower than water or they won't float.

- jacquesm 6y agoFair cop.
- praptak 6y agoI was trying to hint at the fact that "boat density" is not a very well defined concept.
- jacquesm 6y agoHehe, but still, it is a very funny remark and it points to a large assumption in the gggp: that all boats will float. They do, right up until you smash them into icebergs and such. On a technicality such an event changes their density considerably, assuming we take that to mean 'everything inside the volume circumscribed by the hull', after all, whether you insert all that water through a hole in the front or in the top doesn't really matter, as long as the air gets displaced that will do the job nicely.
- praptak 6y agoYup, that's what I meant although it is not exactly "volume of the hull". The boat density should be something like "density as you would calculate it for any solid object" plus "all air below the water line". So solid parts always count and air only counts if its below the water line. This way Titanic counts as just a heap of steel (and doesn't float) and Ever Given counts as steel-air mix (and floats).
