It would be much easier to determine the weight of the water it displaces, if you are unable to place the boat on a scale. Place the boat in the water, mark the water line on the hull. Remove the boat from the water and measure the dimensions or volume of the hull below the water line. then multiply this dimension by the density of water, 62.4 lbs/ cu. ft. (or 1 Kg/dM). The result will be the empty weight of your boat.
for instance a flat bottomed boat, 18 ft long, with a 6 foot beam, drafting 4 inches will displace approximately 36 cu. ft. of water this corresponds to a weight of 2220 lbs.

to calculate the recommended occupancy for any boat under 20ft: length times width divided by 15 L x W / 15 = Maximum occupancy
Not necessarily. The amount of water displaced by a boat depends on its weight and design, not just the material it's made from. A heavier metal boat can displace more water than a lighter fiberglass boat, but if the fiberglass boat is larger or designed to carry more weight, it could displace more water. Ultimately, displacement is determined by the volume of water pushed aside, which is influenced by the boat's overall weight and shape rather than material alone.

The weight of a 17.5 ft fiberglass bass boat typically ranges from 1,200 to 1,600 pounds, depending on the design and features. Factors such as the boat's construction, materials used, and additional equipment like motors and electronics can also influence its overall weight. Always check the manufacturer's specifications for the most accurate information.
To calculate the buoyancy of a cardboard boat, you need to determine the weight of the water displaced by the boat. This can be calculated by multiplying the volume of the submerged part of the boat by the density of water. The buoyant force acting on the boat is equal to the weight of the water displaced.

Fiberglass is actually very flammable.
To calculate the depth a boat is submerged in water, you can use Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the water displaced. By comparing the weight of the boat to the weight of the water displaced, you can determine the depth the boat is submerged. This can be calculated using the formula: Depth submerged = (Weight of the boat) / (Density of water * g), where g is the acceleration due to gravity.
To calculate the weight of ballast for your boat, first determine the boat's total weight and the desired center of gravity. A common rule of thumb is to add ballast equal to 10-15% of the boat’s weight for stability. You can also use the formula: Ballast Weight = (Total Weight x Desired Stability Factor) - Current Weight. Ensure that the ballast is distributed evenly to maintain balance and safety while sailing.
I would think a fiberglass boat is better than a wooden boat because a wooden one can rot and would be hevy to move weres the fiberglass boat wont rot and is light so would be easy to move.
A sponge and some fiberglass sealers works the best on a fiberglass boat. There are other fiberglass cleaning material available depending on what your particular need is. For just basic cleaning, I would go with the sponge and fiberglass sealer.
