Determining the length of a boat
I am trying to find out how the length of a boat is determined for
registering. Is it from the bow to the stern including the pulpit and the swim platform? What if the swim platform is not "fixed" (moves up and down) to the hull. This is for Canadian Waters |

Hi;
It is what form 4A says. I've just registered my boat in Toronto Adam *************** Length overall (LOA) is the length of a ship in metres from the fore part of the uppermost end of the stem to the aft side of the aftermost permanent structure of the ship, not including guards or rubbing strakes, spars, platforms, outboard motors, Z-drives, jet drives, or transom-hung rudders, but is to include any additional enclosed hull volume that is to be added to the hull in the form of detachable or fixed volumes such as blisters, sponsons, bolted stern appendages, etc. (see figure below) ****************** "The "Don"" wrote in message ...

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. Peggie Adam wrote: Hi; It is what form 4A says.

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.

What if the swim platform is not "fixed" (moves up and down) to the hull. This is for Canadian Waters 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. |
