Determining the length of a boat

That's a bit different from the US Coast Guard definition. Here, (actual
wording is mine...I don't have the form in front of me) the LOA is
measured in feet, and is measured over the centerline from the foremost
part of the hull (which would not include anything integral to the
deck), excluding any bow pulpits, bumpkins or other appendages, but
INcluding rub rails...to aftmost part of the hull, excluding any motors,
mounting brackets, davits or other appendages attached to the hull. That
would exclude any bolted on swim platform, but would include swim
platforms that are an integral part of the hull mold.

So technically the same boat could be considered to be 2-3' longer in
Canada than in the US.

None of the above applies to harbor masters' definition of length...they
include everything that occupies space.

Thanks Adam,

I found the document you listed below. So, The way I read this.. one
would messure from the bow to the end of the swim platform.......

Thanks again Adam.

That's how I understand it. The one bugaboo around here (Oregon) is the
width ...if a cop pulls you over, they drop a plumb bob from the outermost
'anything' down each side of the boat and measure the distance between the
points. This is for the purpose of ticketing you for towing something wider
than allowed without a proper permit. Licensing and dock rentals appear to
use the USCG rules for length.

You could also measure it by the International Tonnage Convention of
1969.

Basically the greater length of either stem to centre of ruddder stock
or 96% of the waterline length at the waterline at 85% of the least
molded depth. Means with a vertical stem and Titanic style cruiser
stern a vessel can be longer than 24m overall, but less than 24m under
this convention. In fact one can get away with about an extra 90cm of
boat length.<!-- ~MESSAGE_AFTER~ -->
