Brendan is wrong again.

"Freeboard" is what my kids have and and the "gunwale" is what we have on the bow for shooting dolphins.

Finally a sensible solution - thanks John.

"Hull" is where they made my caravan and "Topsides" - refer to the flesh supported by a Wonderbra.

Merry Xmas and Happy New Year to you all.

The topmost plank of the hull is the sheerstrake, and the gunwale is an addition to that (it is an addition to the hull planking) a small wooden strake sometimes added to this is called the gunwale capping. If bulwarks are fitted the gunwale will be above this - but sometimes the bulwarks are referred to as gunwale.
Generally the term gunwale refers to the top plank (above the sheerstrake) in an open boat, which would be the bulkwarks of a boat fitted with a deck.
Topsides is the hull area out of the water (freeboard). The bit in the water is the 'wetted area', sometimes called the waterplane area.

Nice summary

I think what is confusing people, is that they are trying to apply these terms to modern grp powerboats, and the terms don't often apply to that style of boat. There are no Gunwales, Sheerstrakes nor Bulwarks on most modern powerboats

Even then, the terms seem to apply to different builds of boats, and there are differences of opinion into exact terminology?

Topsides and Freeboard are much easier to apply. Hull above waterline, and vertical measurement of the same - though even that is open to discussion. In a sportsboat, the deck and hull lines are not the same, as the hull is joined to the rest of the boat below the deck line?

Agree, the best summary. I tend to prefer topsides to superstructure for small boats. To me, superstructure applies to big ships, liners, etc like the new QM2.

By the way, from pictures she looks like a real ship - not like a glorified block of flats afloat.

As she's a real ship I will expect her to give way to me 26' under sail in mid channel - OK!
