Buying Guide

Keel Protector Buying Guide

Yes, a keel protector is not like a phone or laptop that you have to dig into to know which ones are the best. It is quite a simple but handy item to have. However, there are still certain things that you need to be aware of.

Without primary knowledge of the keel protectors, you will just go and buy any. And while it may work and protect your boat from a few scratches but it might not be the optimum solution.

Thus, you have to ensure that you buy the right thing. And for that, we are here to help you out. You see, we have dug deep and found out the main things you should focus on while buying an aluminum boat keel protector. Here they are-

Compatibility Of The Keel Protector

The first and most important factor that you have to ensure is the fact that the keel protector is actually compatible with the aluminum boat or not. You see, there are many keel protectors in the market.

But not all of them are for aluminum boats. The majority of the time keel protectors are made for fiberglass boats since they are quite fragile and prone to scratches. However, don’t be disheartened, there are some that work on aluminum.

Now, it is difficult for keel protectors to stick to the aluminum surface. This is because the aluminum oxide that is present on the surface of boats does not let the protector adhere to the surface properly especially if the aluminum surface is painted.

The keel protectors need to be specially designed so that they can be stuck to the surface of the boat. Otherwise, you will see the keel protector coming off quite easily leaving the boat out in the open for any scratches.

Adhesion Property Of The Protector

Another thing to consider is the adhesion property. If you didn’t know already this is the amount of sticking power a keel protector has. Now, in this case, you do want a strong adhesion. This is because the boat will be going underwater.

Thus, the pressure it will feel from the water colliding against it will be quite high. Hence, you want the keel protector to stick to your boat. Thus, it is important to have something quite powerful to overcome the tides themselves.

Appropriate Size To Cover A Boat

One more factor that does play significant importance when choosing the keel protector is its size. You see, the size of the keel protector has to be the right amount otherwise it will not cover the boat.

And quite often we look for something that can cover the boat from all angles. This way, the boat stays well-protected from all angles.

So, how much aluminum keel protector do you need for your boat?

Well, we wish that the answer was straightforward. But the thing is the amount needed actually depends on the boat’s size. Plus, the width and length of keel protectors vary.

However, to give you a general idea we have prepared a list. This shows the length of keel protectors needed for boats of various sizes.

5 ft 16 ft

7 ft 20 ft
8 ft 22 ft
9 ft 24 ft
10 ft 26 ft
11 ft 28 ft
12 ft 30 ft

Easy Installation Factor

How to install an aluminum boat keel protector?

To install a boat keel protector you have to first mark the place. Then clean it using alcohol. After that, position the keel protector and bend it over a bit. Lastly, remove the liner to adhere the protector to the boat.

Should I put a keel guard on my aluminum boat?

It is a given fact that aluminum boats are quite scratch-resistant. However, a little extra protection can never go wrong. So, with a keel protector, you can keep the aluminum guard safe from all first scratches and dents.

Do keel guards affect performance?

No, the keel guards do not hamper the performance of a boat in any way. They, in fact, help to increase the speed and handling capacity of the boat sometimes.

Do I need a keel guard on my boat?

In general, a keel guard is not necessary on a boat. However, there are some boats – such as centerboard boats – where a keel guard is required to protect the propeller from hitting the ground while the boat is dockside.

If you’re unsure whether or not you need a keel guard, it’s best to consult with your boating dealer or manufacturer.

What are the 3 types of the keel?

There are three main types of keel: a flat keel, a bar keel, and a duct keel. Each has its own advantages and disadvantages.

A flat keel is the simplest type of keel and is usually found on smaller vessels. It’s just a narrow strip of metal that sits on the bottom of the boat and helps to keep it from floating. Flat keels are generally less stable than other types of keels, so they’re typically only used on smaller boats.

A bar keel is similar to a flat keel but has an extra support structure along one side. This makes it more stable than a flat keel, which makes it ideal for larger boats. Bar keels also tend to be more efficient in water because they help prevent the boat from bouncing around.

A duct keel is unique because it doesn’t have either a flat or bar surface. Instead, it has several small tubes running along its length. These tubes help to create more lift and make the boat more stable in water. Duct keels are usually only found on larger vessels because they require more support to stay afloat.

That’s about it for the best aluminum boat keel protector.  We hope that by now you got an idea of what to expect from a keel protector. Make sure you choose the right one for you.
