We've all heard the term "Shipshape," meaning to keep things neat and tidy. So when it comes to your hull, decking and other parts of your craft that get exposed to the elements, it's a sound piece of advice.

Below the surface, your vessel is continuously under attack from all manner of corrosives and organisms. And it doesn't end there. The deck and exterior are prone to just as much weathering and deterioration.

The sea is a harsh environment, and you need to keep on top of your maintenance. One of the easiest ways to prolong your vessel's life is to keep everything shipshape, clean and good as new with the best boat soaps.

With that in mind, I investigated the sea of products (see what I did there?) to offer a list of some of the best boat cleaners and marine soaps available.

Below the Surface

Your boat is continuously exposed to damage from the moment it enters the water. So, what are the common causes of corrosion and deterioration?

Salt

Salt will do untold damage to your hull if left untouched. It destroys, it fades, it weakens and it bleaches.

If you don't believe me, see what damage salt water does to a car. I lived on the south coast of the UK for many years and saw the evidence of what salt in the atmosphere could do to rust and the paintwork of a car.

Luckily, your boat will either be constructed of wood or fiber-glass, two materials well suited to this kind of punishment. However, that doesn't mean you shouldn't maintain them.

Algae

In southwest Florida, in 2018, an algae crisis was declared. A carpet of the stuff swept into the marinas and ports, coating every vessel's hull in green gunk.

It was hazardous to paint, with warnings that it could cause damage. It was even claimed dangerous to human life.

If these harmful algae are left untouched, it coats the surface of your hull and releases toxins that could cause blistering to your surface.

Barnacles

Whenever I see the word "Barnacle," I always end up pronouncing it like a pirate. Who else does that?

Barnacles are damaging little critters that stick to the underside of your hull. Once attached, they can be difficult to remove, and if you're not careful, you cause damage when doing so.

They're the scourge of boaters around the world and an inevitability of the boating life.

Worms

In some parts of the world, the teredo worm will burrow through wooden hulls, much like the woodworm does on dry land.

Your hull is then peppered with tiny holes, and we all know what a hull full of holes means. Before long, you'll find your boat on the bottom of the ocean.

So, now you see what you can't see (Is this making sense?).

How Often Should You Clean Your Hull?

A lot depends on your location, usage and the water temperatures you sail in. If you notice a loss in performance or handling, it could be that you have a lot of algae or barnacles attached to the hull, which can impact how the boat behaves.

The general rule of thumb is you should jet wash and clean your hull every three months. This is the ideal, especially if you have a smaller craft that you can drag out of the water on a whim, but for larger vessels, it might not be practical. In this case, it would be wise to conduct a bi-annual or annual inspection.

Multi-surface Cleaners

For the lightest of cleaning tasks, it's possible to purchase a multi-surface cleaner that caters to wood, fiberglass, steel and all other elements of the exterior of the boat. Better Boat's Boat Soap is one such product that cleans hulls, wood, glass and steel in a spray application.

It comes in one-gallon containers and is always handy to keep aboard for the day-to-day chores. You can even use it for pots and pans.

It helps to create a water-repellant barrier and protects against the rays of the sun. These products are inexpensive, and any novice boater can use them.
