Taking a measure of your boat cover size is not just about getting the right fit. It's about ensuring the performance and durability of the cover that protects your precious watercraft. Why you ask? Let's delve into the specifics.

When it comes to safeguarding your boat from the elements, getting the accurate dimensions of your boat cover is crucial. A properly sized cover provides optimal protection, reducing the risk of damage from sun, rain, snow or dust. It also minimizes moisture buildup, which can lead to mold, mildew and other unpleasant issues.

But what happens if the cover doesn't fit right? An oversized cover flaps around during trailering, resulting in potential wear and tear. On the other hand, a too-small cover might not fully protect your boat or could even cause stress on certain parts due to strain.

Does this sound complicated? Don't worry! You don't need a degree in marine engineering to get this right. With our comprehensive guide, measuring your boat cover size will be as easy as sailing on a calm sea. Ready to embark on this journey? Let's get started!

1. Understanding the Importance of Accurate Dimensions

Choosing the right size for your boat cover isn't just about looks. It's a crucial factor that affects how well the cover works and how long it lasts. Here's why getting the measurements right is so important:

Trailering Issues

A boat cover that doesn't fit snugly can cause big problems when you're towing your boat:

  1. If the cover is too big, it acts like a sail, catching the wind and making it harder to tow. This not only makes driving more difficult but also uses up more fuel.
  2. On the other hand, if the cover is too small, it won't cover the whole boat properly, leaving some parts exposed. This can lead to the cover coming loose and flapping around or even coming off completely while you're on the road.

Installation Difficulties

Putting on a boat cover should be simple, but if it doesn't fit right, it can make things much harder:

  1. When a cover is too tight, it's tough to fasten the straps or zip it up properly. Sometimes you have to use a lot of force, which could end up damaging both the cover and your boat.
  2. If the cover is too loose, there will be extra material that needs to be tucked in or secured somehow. This can make it tricky to install correctly and might even cause water to collect on top of the cover when it rains.

Having accurate measurements means that your boat cover will do its job well, protecting against these common problems during towing and installation. By measuring carefully, you'll get a cover that fits perfectly, making it easier to put on and giving your boat better protection.

Next, we'll show you exactly how to measure your boat so you can find the perfect fitting cover.

2. Step-by-Step Guide: How to Measure Your Boat Cover Size Properly

Accurate measurements are the cornerstone of selecting a boat cover that fits perfectly. The process involves two key steps: measuring the boat length and width. This guide will walk you through both procedures, ensuring you get the most precise dimensions for your vessel.

Measuring Boat Length:

The boat length is measured from the tip of the bow to the furthest point on the stern. This includes any protrusions beyond the stern such as swim platforms or motor brackets. Here's how:

  1. Start at the tip of the bow: Place the end of your tape measure at the very front of your boat, also known as the bow.
  2. Stretch tape to stern: Extend your tape all the way to the farthest point at the back of your boat, or stern. Be sure to include any fixed protrusions/bimini or hard tops in this measurement. The tape measure must go all the way over the top of the boat.
  3. Consider aftermarket extensions and options/upgrades: If your boat has additional elements like swim platforms, motor brackets, or manufacturer options/upgrades, include these in your measurement.

Remember, these extensions can affect the cover's fit and performance, so it's essential to account for them.

Measuring Boat Width

The boat width is often referred to as beam width and represents the widest point of your vessel. Here's how:

  1. Locate widest point: This is usually found in the middle section of your boat.
  2. Stretch tape across: Extend your tape from one side of your boat to another, making sure it crosses over the widest point.

Note that removable items like bumpers or detachable parts should not be included in this measurement. The goal here is to measure only permanent parts of your boat's structure.

Tips for Accurate Measurements

  • Use a flexible tape measure: This type of measuring tool can easily navigate curves and corners on your boat, giving you a more accurate reading.
  • Measure twice: A common rule in all types of measurement tasks. It helps to confirm the accuracy of your dimensions.
  • Record your measurements as you go: This prevents any confusion or memory errors later on.

By following these steps, you'll have the accurate dimensions needed to select a perfectly fitting boat cover. But what if you're considering an oversized cover? The next section will delve into the pros and cons of this choice.

Outboard Motors

Measure with the outboard motor in the stored position, when ordering allow between .05 and .75 extra in length to allow the cover to wrap underneath the outboard motor.

3. The Pros and Cons of Oversizing Boat Covers

When choosing a boat cover, you might consider getting one that is slightly larger than the exact size of your boat. This is known as oversizing. While there are advantages to this approach, it's important to also think about the potential disadvantages.

Pros of Oversizing Boat Covers:

  • Enhanced Weather Protection: An oversized cover may extend beyond the edges of your boat, offering additional shielding from rain, snow, and UV rays. This added coverage means less exposure for your boat's surface and more defense against weather-related wear.
  • Space for Accessories: Boats often have extra gear such as antennas, fishing rod holders, or trolling motors. A slightly larger cover can accommodate these items without stretching or stressing the material.

Cons of Oversizing Boat Covers:

  • Aesthetic Concerns: A baggy cover may not provide the snug appearance that many boat owners prefer. Excess material can gather and create an unattractive look that doesn't complement the sleek lines of a well-maintained vessel.
  • Wind Damage Risk: Loose fabric is prone to billowing in strong winds, which can lead to tearing or abrasion. Additionally, the movement might chafe the boat's finish or even cause the cover to detach and become ineffective.

By considering these factors, you can make a better decision on whether getting a slightly larger cover is right for you. It's important to remember that while having some extra room can be useful in certain situations, too much excess can create new problems that affect your boat's protection.

4. Seeking Expert Advice for the Right-Sized Cover

Finding the perfect boat cover can be overwhelming, especially when it comes to getting the right fit. While knowing how to measure your boat cover size is important, getting advice from experts can be incredibly helpful.

Why Seek Expert Advice?

Boat professionals have extensive knowledge and experience in the industry. They can provide valuable insights and guidance on choosing the best cover size for your specific vessel. Since every boat is unique, with different designs, models, and manufacturer options, there may be certain factors to consider when selecting a cover. For example, let's say you own a fishing boat that has a custom T-top installed.

 This feature could significantly affect the type and size of cover you require. In such cases, consulting an expert becomes invaluable as they can navigate these specific situations and ensure you get the best fit and protection.
