The search, discovery, refinement, and resource control of fuel has a rich and very sordid history. But just like a conversation on a boat…
The rules make it very clear: safety is paramount, and you must always maintain a safe distance from other vessels.
A semi-displacement hull is designed to offer a balance between the high-speed capabilities of a planing hull and the efficiency and stability of a displacement hull.
To be prepared and understand electrical power usage on a modern vessel, it is important to learn a few basic terms and concepts.
“Weighing the anchor” simply means raising it. However, forgive your crew member if they yell back “40 pounds” after you ask them to weigh the anchor.
Here again, we are discussing catamarans and twin-drive monohulls for the sake of their similarity and non-duplication.
A planing hull is designed to rise and glide on top of the water at higher speeds, rather than plowing through it like a displacement hull.
Mooring a vessel means attaching it to a float that is firmly and permanently anchored to the sea bottom.
Marine engines on powerboats, whether gasoline or diesel, use two primary cooling systems to manage engine temperatures: the raw water system and the coolant water system.
