Boat lengths , waterline or deck ?
Discussion
When an Ad. gives the length of a boat, is it measured at the waterline or the deck ?. Only on a speed boat it can make a big difference at the bow. Also am I correct in assuming that the length (which ever way) wont include the drive (inboard engine) poking out the back of the transom ?. This is all with regard to storing on land & buying a trailer .
Thanks

Length quoted for most ships/boats is usually LOA - length overall. This is the maximum length of a vessel from the two points on the hull measured perpendicular to the waterline. So, deck (sort of) rather than waterline (which would change depending on the draught of the vessel anyway).
LOA is normally absolute length overall (hence the use of the word 'overall') to include pushpit, pulpits etc etc). After that you have LOD (length on deck) which is effectively the physical hull length (ie without the bolt-on parts) and then you have LWL.
There are other measurements commonly used, mainly for the purposes of registration. For instance, above 24m the rules and regs on driving yachts changes dramatically, so you will always see a variety of yachts measuring in at 23.99m on their certificate of registration which are actually significantly longer in terms of LOA or even LOD. Physical aspects such as bulwarks and bathing platforms are often disregarded as they are not part of the original hull moulding.

i remember back in the earluy 90's when fairline changed their naming/measurement policy for their model range.
you ended up with a targa 30/33, a targa 33/36 and so on... the difference was the LOA to the LOD... quite confusing! (most notably if you said you had a targa 33)
i still laugh when people say that don't want a turbo 36 as they only want the larger turbo 38... same bloody boat chaps!
