A question about boat weight and displacement
 
writes:

You have not answered: What state do you live in?


This is relevant to the weight of a boat how?

How anonymous do you intend to remain?


As much as possible. I have several concerns, all of which are
not relevant to the questions being asked. If I lived in North
Carolina, the vessel would weigh the same as if I lived in North
Dakota.


Go down to the local county fair.
There's a guy there who for $2 will guess your weight. Bet he does boats, too.
That's what you're expecting the people on
this group to do.....guess the weight.

I'd ask "where's the boat now", but probably get a smart ass reply about how I
still hadn't told you what the boat weighed.

That's too bad, because if the boat is in a yard with a Travelift, many of
those lifts are equipped with a way to measure the actual weight of a load.
Anything else, whether based on dimensions, listed displacement,
or whatever is a SWAG, and not even all that S in the end.

This mimara guy is a known troll. Remember a while back when he was
pretending to be some foreign guy?



No, I'm new here.

$99,000 !!!! For that much you could buy a REAL truck.

Since you are not sure about the F150 or F250, then you should get a F650.

As far as I know displacement = weight.


Somehow, this doesn't sound right to me.

Certainly the weight of the boat will displace the amount of
water with that same weight (hence the term displacement).


If something displaces X pounds of water, it must weigh X - n to
be able to float. It must weigh less than the amount of water it
displaces, else it will have neutral (or worse, negative) buoyancy.


You aren't thinking this through completely. A boat's weight is equal to
its displacement. In other words, the weight of the amount of water it
displaces (or moves out of the hole in the water it makes when floating) is
equal to the weight of the boat displacing that water. If a boat displaces
X pounds of water it weighs X, if it weighed X-n it would only displace X-n.
If it weighs more it will displace more water until you get to the point it
can no longer displace more water as it has sank/submerged. In a sense, any
boat floating is at neutral boyancy (it is neither rising out of the water,
nor is it sinking) but has lots of reserve boyancy (the part of the hull
above the water line which would displace more water if it was forced down
into the water) to accomodate additional weight that may be added. Or to
provide freeboard to keep waves from coming abord, wahtever. There are a
number of different way displacement is listed. Others get into that in
later posts. I though I'd try to clear up this aspect here.

Having said this, how do I determine how much it weighs, from
limited information, without being there to weigh it?

That said, for documentation purposes the Coast Guard refers to
a tonnage (don't recall if they call it displacement) that relates
only to boat volume, not the weight.


This is very interesting. It also has nothing to do with what I
asked originally. I cannot see inquiring of the Coast Guard about
the tonnage or volume of a 28 foot motor boat. What can they tell
me about how much this vessel weighs, by me inquiring about the
volume of the boat?

I do not understand where you were going with this.

Do you have anything to add that will address the original question?
