At night, a rowboat must display a white light visible from all directions. This can be achieved with a lantern or flashlight. Additionally, if the rowboat is underway, it should also have side lights: a red light on the port (left) side and a green light on the starboard (right) side. These lights help other vessels identify the rowboat's orientation and direction of travel.

To determine how far below the surface of the water the boat's bottom is, we can use the principle of buoyancy. The weight of the boat and its cargo (5000 N) must equal the weight of the water displaced by the submerged portion of the boat. The weight of the displaced water can be calculated using the formula: weight = volume × density × gravitational acceleration. Assuming the density of water is approximately 1000 kg/m³, the volume of water displaced is ( \frac{5000 , \text{N}}{9.81 , \text{m/s}^2} \approx 510 , \text{kg} ), which corresponds to a volume of approximately 0.51 m³. Given the area of the boat is 4 m², the depth the boat sinks is ( \frac{0.51 , \text{m}^3}{4 , \text{m}^2} \approx 0.1275 , \text{m} ) or about 12.75 cm below the water surface.

Cabezas Raft was blown ashore on the coast of Puerto Rico. Specifically, it landed near the town of Fajardo, which is located on the northeastern part of the island.

The Hadza, a hunter-gatherer group in Tanzania, traditionally do not use rafts. Their lifestyle is primarily centered around foraging and hunting on land, and they typically rely on walking or swimming for water navigation. While they may have occasional interactions with water bodies, there is no evidence to suggest that they employed rafts as a means of transport.

Water moves a raft primarily through the principles of buoyancy and displacement. When a raft is placed on water, it displaces a volume of water equal to its weight, allowing it to float. As water flows around and beneath the raft, it creates pressure differences that push against the bottom and sides, propelling the raft forward. Additionally, currents and waves exert force on the raft, helping to move it along the water's surface.
