Default Re: 25 seafari questions - weight calculations

Quote:
I just looked at the BUC website and the 2003 2509 WA Trophy OB model is listed as 4400 lbs net weight. The net weight of a boat is based upon buoyancy, and is the weight of the hull, plus power, fuel, persons & gear. It is also called displacement.

For example, my 20' Seafari has a listed hull weight of 1800 lbs. My motor weighs 375 lbs, I carry 28 gallons fuel, and I have a max capacity of 9 persons, or 1455 lbs persons and gear. If we go with the max of 1455, the equation looks like this:
Hull - 1800 lbs
Fuel - 168 lbs
Motor - 375 lbs
Persons/gear- 1455 lbs
Net Weight or Displacement - 3798 lbs

For your 25' Seafari: Hull - 3000 lbs, 105 g. Fuel - 630 lbs, 7.4 L sterndrive(1982 weight w/ TRS) - 1244 lbs, Max capacity persons & gear - 1619 lbs = 6493 lbs net weight.

So an "apples to apples" comparison using your examples is:
2509 Bayliner Trophy = 4400 lbs net weight or displacement
25' SeaCraft Seafari = 6493 lbs net weight or displacement

In no way am I opposing what you are saying. In fact, my signature should read "wisdom is learning from Fr. Frank" by now but this topic is of particular interest to me. Not just because we're talking about my favorite 25' boat but also because I'm in the scale business.

On the Railroad, we refer to net weight as the weight of product in a rail car not including the light weight. The 2 added toghther would equal the gross weight.

In my mind, displacement should be the gross weight.

Are the terms different on the water

BTW Nuthinfancy I`ve never had the opportunity to check the dry weight of ours but I think Fr. Frank`s right on at around 6 to 7000 lbs displacement according to the guy that stores our boat for the winter (although he hasn`t actually weighed it). I guess he just has an idea compared to other boats he stores.
