Understanding The Parts Of A Power Boat


So you just got yourself this kickass powerboat and are all set for an exhilarating ride? Why not take a few minutes to familiarize yourself with its parts and how everything works? It could mean the difference between a breathtaking heart race and a disaster, you know!

Parts Of A Power Boat

If you own a kayak, (whether a sit inside or sit on top kayak) then some of the powerboat parts we are going to discuss below may not be new to you.  Basically, the parts of a powerboat include the following:


This is the waterproof body of a boat. The inside consists of frames that run the length and width of the boat. The hull is actually the part that keeps you dry.


If your motorboat is a recent model, then this part may be missing because nowadays, the engines in powerboats can generate enough power to move them through the ocean. All in all, a keel is an important part of a boat because it keeps it stable.

It is the bottom-most structure on which the hull is built. Aside from providing stability, this part also generates power that pushes the boat forward.


The spinning blades are located at the rear of your vessel. A boat propeller rotates to power the watercraft forward or backward. The way this part works is that it converts the spinning power into thrust that aids with the boat’s movement.


Several powerboat parts fall under this category. The common three include the bow, the deck, and the gunwale.

The way the bow is shaped is that it lifts the vessel with the waves instead of just cutting through them. The curve on the deck, also known as sheer together with the tumblehome and flare also helps in maintaining buoyancy.

Flare is actually the outward turn of the boat’s hull and just like other curves, it too increases displacement. The reverse of a flare is a tumblehome. The gunwale is the upper edge of your boat’s side.

On a side note, the deck is a nice place to pass time with your friends. Just bring a few boat deck chairs and you will enjoy the most relaxing moments of your boating trip.


How well your watercraft handles the speed it moves at partly depends on the chine. A chine is the form or appearance of the hull’s part that sits underneath the waterline.

If it has a round shape or shallow angle, it is referred to as a soft chine. If the shape is square, it’s called a hard chine. Motorboats with a soft chine have stronger horsepower while those with a hard chine provide more stability.



This is the shape of your boat’s backside. The appearance of your watercraft’s tail plays an important role when it comes to preventing the boat from capsizing or somersaulting. Powerboats with a square stern provide a wide surface area for the waves to act upon than those with round sterns.


This is the sunken part of your watercraft that provides space for you, your crew members, and guests. Usually, there is a boat seat where you can sit and relax as you ride. You can also go ahead and add in a boat carpet for extra comfort.  A boating trip should be enjoyable and making your space as comfortable as possible is the first step to achieving that goal.


Another section that is included in our list of powerboat parts is the cabin. This is the enclosed area of your watercraft.

Depending on the size of your vessel, a cabin can house a bunk bed, a bathroom, and could be the perfect storage for your boating equipment. Think about your first aid kit, a boat anchor rope, dry bags, and anything else you don’t need in your cockpit.

Swim Platform

This is the part of the watercraft where boaters can embark and disembark easily for a swim. You can attach a boat ladder for easier access.

Port And Starboard

The port is on the left side of your motorboat while seated facing forward. Starboard will obviously be on the right side. Can’t remember which is which? Here is a quick rule of thumb – the word “left” has four letters and so does “port”!

Globo Surf Overview

Learning the parts of a powerboat can be intimidating but once you got these at your fingertips, riding your vessel and communicating with other boaters will be so much fun. Just remember to observe boating safety whenever you are out there. A life jacket will also be a good companion on such a trip just like it would be on a canoeing or kayaking adventure.
