When we’re investing money and time into something, it’s not unusual to want to name it. We do it with most of our vehicles, from cars to motorbikes and motorhomes to boats. It kind of gives us a sense of personal ownership. It’s no longer a lump of metal or wood; it’s something we have an emotional attachment to. After all, these are vehicles that you may have a wonderful adventure with or even make into your tiny home.[Read more…] about How to Name Your Boat
If a car driver uses ‘cruise’ to control a car, the vehicle will achieve its maximum performance efficiency. To do something similar for a sailing boat, you would need to calculate the hull speed. This will give you the average speed that suits the type of craft you are sailing. That’s why you need to know how to work out the average speed of a sailboat.
What is a Sailboat?
It’s a boat that primarily uses wind to propel it forward. There are other factors, such as tidal direction and design of the boat, that also help to move a sailboat. For the wind direction, a sailboat uses sails instead of an engine. Although some sailboats are also fitted with small engines to help with docking, among other things.
How Do You Calculate a Journey?
In the 15 century, Columbus’s Caravels sailed across the Atlantic at an average of 8 knots. We haven’t moved on much at today’s average speed of a large schooner, which is around 10-12 knots.
Remember that 1 knot is about 1.15 mph.
Sailing a boat is a challenge and takes skill to start, and significant talent to excel at, with specially built racing yachts achieving much faster speeds. A large schooner can cover up to 200 miles a day, but the speed will depend on a few important factors. See our article on how long to sail 100 miles for more information.
For top speeds sailing boats rely on the ocean current and the wind. It takes time and patience to plan for both of these factors to flow in the direction you want to sail.
The initial calculation for a long journey can be made with a simple calculation.
- How many miles you are going?
- Divided into how much time you want to take to complete the journey.
But, for a sailing boat, whether that calculation is ‘do-able’ will depend on three very important factors:
- The length of the sailing boat.
- The type of hull.
- The wind speeds.
These three factors are vital in calculating the average speed of a sailing boat.
Why Does Length of the Sailing Boat Matter?
Generally, the longer the boat, the faster it can cut through the water. A large boat is considered to be over 50ft long. For instance:
- A 16-foot boat can move up to 5 knots per hour.
- 50 ft boat can move up to 7 knots per hour.
- 244ft boat can move up to 16 knots per hour.
Showing that size makes quite a difference to speed when it comes to sailing boats.
What are the Two Main Types of Hull That Affect Speed?
There are two main types of hull, that play a major role in the speed of a sailing boat.
A ‘mono-hull ‘is used in an everyday sailing boat. You may also hear it called a ‘displacement hull.’ It’s also a single hull and is placed under the water. This type of hull pushes the water away from the boat, so the craft can move smoothly as it cuts through the waves.
To move faster, the hull needs to above the water level. This is also known as a ‘planing hull.’ The situation of this hull makes the craft quite buoyant, so it’s less stable. That’s why a sailing boat with a planing hull needs more than one hull, which is known as a multi-hull. Catamarans are common multi-hulled sailing boats. You may find pontoon boats as well as others that fit this category as well.
These are the favorable hulls for racing boats.
What Does Wind Power Mean?
One benefit of using wind to power your craft is the beauty of how you can utilize nature instead of an oily engine. Going faster with wind power means it will not harm the craft in any way if it’s done right.
What is the Average Speed of a Sailboat?
There are a ton of variables that go into the average speed of a sailing vessel, including the wind and water condition, the skill of the sailors, the type of boat, etc. But we can give some general ideas using the following estimations.
To calculate the average hull speed of a monohull, the length of the boat is the most important factor. When we talk about the length of the boat, it is the waterline length (LWL) that matters, and not the overall length (LOA).
The LWL is the part of the boat that sits at the waterline level. Also, note that the LWL is always less than the LOA.
What is the Scientific Calculation for the Average Speed of a Sailboat?
This is where you’ll need that scientific calculator so you can work out the square root of the LWL.
Let’s take a boat of 35ft in over length (LOA).
It’s LWL, from bow to stern and not including the rudder, will be approx. 28ft.
First, calculate the square root of the LWL, which for 28ft is 5.3 (rounded)
Next, multiply the square root of 5.3, by 1.34. (This is the accepted scientific measurement of the wave crest between the bow and the stern. The wave crest creates the bow wave in the wake of the boat).
Our calculation now looks like this:
5.3 x 1.34 = 7.09
The average speed of a 35ft (LOA) sailing boat is 7 knots.
Here’s the same calculation for a 15ft (LWL)
Square root of 15 = 3.9 (rounded).
1.34 x 3.9 = 5.189 which gives us 5.2 knots. (rounded).
To increase speed, you would need to learn how to harness the wind and the tide in your favor.
Speed, for many, can be a real adrenalin hit. The present world record speed for a sailing boat was achieved in 2012 at 68 knots (78mph).
Whereas, the average speed of a high-end racing sailboat is around 15 knots (17mph). This type of sailboat tends to be lighter. Plus, it will most likely have a double, or even triple (tri), hull, hence the planning effect.
But a cruising sailboat tends to go at an average of 5 -8 knots.
The longer the sailboat, then the larger the crest wave. This results in it moving forward at a bigger distance than a smaller boat creating a smaller crest wave.
The shape of the hull also affects the speed. Imagine a fat-tub of a hull to a boat; it’s going to move much slower than a slimline hull, even if they’re equal in length. Design plays an integral role in speed.
Plus, regular maintenance of your sailing boat too. This also helps to ensure its efficiency to reach top speeds. Sails must remain intact with no tears or holes and be properly tensioned. The mast must be solid. The skill of the sailor is also an essential element in achieving top speeds for a boat. Only a skilled sailor can take advantage of the winds and tide.
There are a few pieces of marine equipment that you want to pay particularly close attention to ensure functionality. Some of these may be necessary in case of emergencies, while others may help to prevent those very same emergencies from occurring in the first place. Bilge pumps fall into the latter category.
As the name suggests, a bilge pump is a pump that is used to remove water from a ship’s bilge. Most of the time it’s just removing small bits of rainwater, errant wave spray, etc., that get into the boat. But not always. Sometimes it’s working to remove water from the vessel before the boat sinks!
Whether you’re going to be relying on a single bilge pump or multiple ones, you’ll want to be sure that the model you select is capable of reliably removing water from your vessel. Unfortunately, it’s hard to know what to expect from a bilge pump until you get your hands on it. This is where our review guide will come in handy.
Over the course of today’s guide, we’re going to take a look at ten of the best bilge pumps on the market, and we’ll compare and contrast them so you know exactly what to expect.
We’ll start off with the Best Boat Bilge Pump, the Attwood Sahara S500.[Read more…] about Best Boat Bilge Pump

When you look at your boat’s floor, do you think “hmmm, not such a good look?” If so, it’s time to switch out your floor. But what to get? There are many types of boat flooring, each with advantages and disadvantages.
In this article, we’ll look at several of the most popular Boat Flooring Options and give you some context to help choose the right material for your needs, your vessel, and your budget.
Why Choosing the Right Boat Flooring is Important
It might not seem like it, but boat flooring is critical for a variety of reasons. It not only allows you to decorate your boat according to your preferences but it also protects some portions of the boat from damage. And in certain cases, the right boat flooring also helps to prevent those on the boat from slipping and damaging themselves!
A steady grip can life and death.
The windlass makes operating a boat so much easier. This age-old invention has helped bring up anchors for centuries.
Today’s anchor windlasses are electrically operated and designed to quickly drop and lift your boat’s anchor into the ocean. Depending on the size of your boat and the quantity and types of anchors you have, you may need one or more windlass.
Anchoring your boat is often one of the most dangerous parts of boating. If you ask any experienced sailor, almost all of them will have at least one story of the time they sliced their hand open tossing the anchor, or got off-balance and busted their behind on the deck.
A mechanical windlass allows the anchor to be instantly dropped or withdrawn from the boat just like a winch. No more sketchy balancing acts on the tip of your boat!
In today’s article, we’re going to take a look at some of the top windlasses on the market. We’ll start with the best anchor windlass, the Lewmar V700.
