The weight of the vessel as could be measured on a scale versus the calculated displacement are not quite the same, though the difference is not enough to concern boat owners. Displacement is the volume of water that is displaced by the hull of the vessel measured in pounds or tons. This derives from a math calculation made by naval architects during the design process. No one actually ever physically measures the displacement of a hull as that is far too costly to do. Displacement as a representation of boat weight is no longer used by pleasure craft builders, though it is always used for ships. more

So which is the proper length to use? Since the pulpit does not represent useable space on the boat, the proper length to use is the length exclusive of the pulpit, or LOD, though that number is most often expressed as LOA.

Then you have to figure weights added during fitting out. Typically, this will be about 10% of the dry weight, assuming that you are not making any major additions like a tender, davit or other particularly heavy additions. here

Confusion can arise because the pulpit is an integral part of the deck. Therefore, to call it LOA is not inaccurate. Some refer to length with and without pulpit, which eliminates all confusion. If the builder leaves any doubt about this, be sure to clarify it.

Do You Know What Dry Weight is When Towing Your Boat? more

When new boat owners purchase a boat, they often do not think about what they are going to do with the boat if they need to transport it from one place to another. When driving your boat form one marina to another, or when driving to take it into storage, it is common for the boat owner to drive the boat onto a trailer, hitch the trailer to his or her automobile or truck, and two it to the destination.

You will also need to be aware of the towing capacity of the hitch you purchase, and for the same reasons. If you use a hitch that’s not rated for the tow load of your boat and trailer, the hitch can break off, leaving your boat behind while damaging the rear end of the vehicle. here

However, while we all see boat owners towing their boats behind their vehicles, many new boat owners do not realize that they when they buy a boat, the deal doesn’t necessarily include the trailer. Sometimes, though, a dealer will include a trailer at a reduced price in order to sell the boat as a package deal, but is much more likely that you can get such a package deal when buying a used boat from a private owner.

In reply to the OP, the claimed dry weight of a design could be wildly wrong for a production boat. Nothing unusual in using 5% more resin in the hull, different fittings, optional extras.
Personally I would want a good margin for this, plus loose kit etc. [links]

Something like a farm trailer might be nominally a 'half ton trailer' to carry half a ton, but it will have a plate on it giving the tare. [links]

May be different elsewhere of course. [links]

Thanks for the prompt reply.
Yes, it all adds up and quickly! That was my doubt because the boat I am looking at right now (a Shark 24) has a dry weight of 1T, give or take one kg. My trailer is rated for 1300kg but the trailer itself weighs 280kg, so it is virtually on the limit, giving me only a 20kg threshold. and over here in central EU, the road side police can be a real pain even if you have 1kg more. here

I am selling Cookie Jar and searching for another boat. Although It may seem obvious from the concept of "dry weight" itself, my issue is related to trailer-sailers and my question is "will I be able to pull it or not". and that may be the "small" difference between pulling it myself or having to pay for transport, what would eventually render the deal useless due to costs.

No, Trailed weight is the all up weight of the trailer and its load. The trailer plate should indicate the maximum permissible load, to which the weight of the trailer is added to get the Trailed weight and the manufacturer of the towing vehicle will have set the maximum allowed. It doesnt necessarily solve the problem to pile all the heavy gear in the car to reduce the trailed weight. The towing vehicle will have a MAM figure specified - maxim allowable mass, which is the all up weight of the towing vehicle, its load, plus the trailer and its load. Down here on the S Coast Plod has regular campaigns to check private vehicles towing anything, caravans, boats or whatever. A worryingly high percentage of towed loads are found to have dangerous faults including insecure loads and overloading. BiL now retired was a French Gendarme. He warned me that they were very hot on overloaded cars and often stop and check a loaded GB car because they are often above the manufacturers limit.

Before you get too involved with come-alongs and frames read the above. here

My son has a 3000 lb chain hoist hooked up to a frame made of 6x6 uprights and a 10 foot 6x6 overhead beam (all sistered 2x6's) in his garage. he says he has lifted over a thousand lbs before, no problem. Using two slings and a spreader bar I can borrow from work, we'll lift the boat just enough to clear the trailer and pull it out. I use slings, up to twenty feet long to lift 1800 lb electric motors, 500 lb pumps, stainless steel piping bundles and carbon steel square tubing bundles. The gear we have will handle this boat as long as it is done safely and correctly. A 4 foot spreader bar, the smallest we have, is rated to lift 2000 lbs. Using a double sling basket from a spreader bar will cut the weight in half for for each sling. We can lift the boat ok, I'm not worried about that. Balance is a key word here. The boat must be precisely balanced between the two slings before I'll feel comfortable. A tag line or two can be used to help steady the boat even more. Here's a couple of diagrams from a safety manual they gave us at work to illustrate. I intend to lift the boat a smidgen off the trailer and see how the cross beam reacts. If I feel it's ok to proceed, we will finish the lift. We're still in the planning stage and I wanted to know how much my boat weighed and was not sure exactly what dry weight entailed.

um. why are we slinging such a little boat?

Why don't you simply (?) take it to a truck stop and get on the scales. Subtract the approximate weight of the trailer and you have your weight. What's a trailer weight? 250ish#? [links]

My opinion is you would never get it back on the trailer. easily, of course. Pulling weight and lifting are different mechanics.
