Hull or Topsides

[lanason]

Reading MBM today - I was amazed how many small sports boats now have the windows (so called) in the Hull and not in the topsides. From the front, the boats look like bathtubs - much nicer to have windows in the Superstructure and a lower, sleeker looking boat.

Dont know whether my boat is big or small. But all my holes are in hull. I, we have to remember to shut them at sea. Or maybe sink!! But the headroom and the wide cabin. Plus the easy walk roud flat deck make up for that. Smaller boats with hull windows should be firmly shut IMHO. hull

'Hull is the underwater bit'? I don't think so. My windows (ports) are in the hull (or topsides) not in the superstucture and my boat looks OK. Also gives more use of interior space.

AFAIK the topsides is the part of the hull above the chine and below the hull/deck join ie the bit of the hull which is out of the water. Agree with you though. This type of boat is disparagingly referred to as a bubble boat in the US

Come on Haydn, everbody knows the P35 is the height of stylistic good taste. I'm talking about those Yank sports boats with no sidedecks where you walk thru the windscreen to get to the foredeck and which look higher than they are long

[hlb]

Used to have one of them. Finnished up getting made a set of three foot high railings so not fall off!!

Where's Byron when you want him ???
I have a similar definition of hull and topsides to you. However this means that most round bilge displacement boats won't have any topsides cos they dont have a pronounced chine and the hull/deck joint is usually at deck level. I don't think that this is correct as I've frequently been told by owners of yachts to "MIND MY TOPSIDES YOU FOOL"/forums/images/icons/wink.gif
So come on all ye olde salts what are the correct definitions ??

topsides = from waterline to deck.
Hull is what the builders designed to go in water, take off deck, superstructure etc, and the physical bit that sits in the water is the hull (this includes the topsides if all built in one structure)

[hlb]

This must be of course complete rubbish. Bredan is obviously still in panto mode. It might be caled top side but it is still the hull. This idea of water line is crap anyway. My water line is all over the bloody boat most of the time. So even the fly bridge must be hull. I rwest my case!!

[BrendanS]

Freeboard is the vertical distance between the water line and the deck edge (or gunwale)

Gunwale is not join, on a wooden boat it is the topmost plank, though other definitions include:The upper edge of a vessel's or boat's side; the uppermost wale of a ship (not including the bulwarks); or that piece of timber which reaches on either side from the quarter-deck to the forecastle, being the uppermost bend, which finishes the upper works of the hull.
Usually means the upper edge of a boat's sides, usually with railing

So it's le height of the topsides n'est ce pas.

<hr width=100% size=1>

 

[hlb]

Yes Yes. But is it not fair to say, that the freeboard is just a part of the hull. It is used mainly to discribe how much hull there is above water. (So it dont splosh in). So good boats have bigger freeboards. Still hull though.

[BrendanS]

Nope. Topsides can be at an angle, so longer than the vertical height of the freeboard.

See? .... easy peasy

[BrendanS]

No, freeboard is a measurement, a distance, not part of vessel. Topsides is actual bit of boat above water
