It oxidizes. A zinc block on a boat is called a sacrificial or cathodic anode. It reacts better with the electrolyte (salt water) than the metal on the boat.
To make foil float with pennies, fold the foil into a boat shape with raised edges. This shape creates buoyancy to support the weight of the pennies without sinking. Make sure the edges of the foil boat are securely folded to prevent water from seeping in.
An old chestnut this one. Whilst in the boat, the anchor displaces its weight in water, when under the water and lying on the bottom, it only displaces its volume. As it is made from iron which is much denser than water, its volume is much less than the volume of water which equals its weight. So it will displace less water than before it is dropped.
The windward side of the boat is the side of the boat that the wind is hitting. the other side of the boat that is sheltered from the wind is the Leeward side. In other words ... the windward side of the boat is the side that is closest to the source of the wind.
To effectively maintain a salt water toilet on a boat, regularly flush the system with clean water to prevent salt buildup, use marine-grade cleaning products to keep it clean, and inspect and replace any worn parts as needed to ensure proper functionality and cleanliness.
These guidelines are for larger outboards with planing type hulls, not displacement hulls. Your reference point is the lowest part of the hull, or keel. When the anti-ventilation plate is in line with the bottom of the hull, this is Standard. The engine can be raised 1in. ( 25mm ) above standard for every 10 MPH ( 17km/h ) above 40MPH ( 64km/h ) So if the boat can do over 40MPH ( 64km/h ) the engine can be lifted 1in. If the boat can do 50MPH ( 80.4km/h ) it can be lifted another 1 in. and if possible and the boat can do 60MPH ( 96.5km/h ) the motor can be lifted another 1 in. So if you have an outboard that can run at 60MPH (96.5km/h ) then your engine should be no less that 3 in. above the lowest part of the boats hull. But.... For every 12 in. ( 305mm ) the outboard is behind the transom, or a notch in the transom, the engine can be raised 1 in. ( 25mm ) above standard. The rule in the outboard set up buisness, is that water exiting the bottom of the hull, when on the plane should not be flowing over the top of the anti-ventilation plate, but below it, this reduces drag on the lower unit.
The duration of The Glass Bottom Boat is 1.83 hours.

The distance between the bottom and the keel of a boat is the draught (British English).
The space between the boat's keel and the bottom is the draught.
It is the boat's draft.
to replace the paddle boat and create a faster boat! that was technology back then!
