The waterline length (originally Load Waterline Length, abbreviated to LWL) is the length of a ship or boat at the point where it sits in the water. It excludes the total length of the boat, such as features that are out of the water. Most boats rise outwards at the bow and stern, so a boat may be quite a bit longer than its waterline length. In a ship with such raked stems, naturally the waterline length changes as the draft of the ship changes, therefore it is measured from a defined loaded condition.
Length at the waterline is often abbreviated as lwl, w/l, w.l. or wl.
This measure is essential in determining a lot of properties of a vessel, such as how much water it displaces, where the bow and stern waves are, hull speed, amount of bottom-paint needed, etc.
In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or draft. Higher beam and draft causes higher resistance against the water. This maximum speed, also known as theoretical hull speed, can be calculated using the formula (sqrt of LWL) x 1.34.
How to Calculate a Boats Waterline - Archimedes Principle
This video explains a simple way to calculate the waterline for your cardboard boat. This method works well for most boats that do not have noses that coming out of the water at a angle. The video is meant as a fallow up to my how to build a cardboard boat video and should help new builders understand more about boats. Here is the math I used bellow if you need it...
1. Calculate square ft of boats bottom
2. Total up weight of people who will be in boat and the boat
3. Divide total weight by 62.43 to get cubic ft needed to hold boat up
4. Take cubic feet(step 3) and divide by Square ft (Step 1) this gives water line in ft
5. Divide by .083 to get inches for water line

How to Precisely Measure the Waterline Inside your Boat
Since I want to install a bow thruster in my boat, which has quite a shallow hull, I need to know exactly where the waterline is located. In this video I show you how you can find the waterline from inside your boat. This can be useful if you want to install anything that penetrates the hull, like a through-hull fitting or the above mentioned bow thruster.
