Types of jon boat covers

Universal Standard jon boat covers

The standard model comes in lengths from 15 feet up to 30 feet long for those who want more coverage than what's offered by a smaller size.  It also helps protect against dirt, dust, and bugs when not in use.

Elastic Jon boat cover

Standard Jon boat cover vs Elastic Jonboat Cover

A standard jon boat cover is made from one piece, so there are no seams that might split when put under pressure. The elastic models on the other hand have four pieces that can be pulled tight around the edges using adjustable straps so any gaps will not result in water getting into your boat while it sits outside awaiting use next season. This increased security comes at an additional cost however because these models tend to come at higher prices than their counterparts who require simpler techniques like tying them off with bungee cords.

Trailerable jon boat cover

A trailerable jon boat cover is designed to fit over your Jon Boat and connect to the tie-down points on either side of the Jon Boat. Some trailers have a tongue at one end which you can use to attach it securely with bungee cords or ropes, while other trailers may only be able to accommodate an elastic strap that will hold its front loaders in place.

Custom Jon boat covers

Custom covers for jon boats are made from a variety of materials. The most popular material is canvas, which can be water-resistant or fully waterproof depending on the type and strength of fabric you select. They also come in many different colors that will perfectly match your Jon Boat's paint job to keep it protected year-round.

What materials do jon boat covers come in?

There are a variety of materials that vary from heavy-duty canvas to lightweight polyester. The most popular is the breathable fabric because it offers superior protection with lower maintenance, but for an added cost. Polyester Jon boat covers are the lightest. They can be folded up to a small size for easy storage, but they do not provide any protection from fading or UV damage because they have no breathability. So they should only be used with boats that will stay in one location all season long as if you put them on and then take them off, the cover will have to be re-stretched every time. Their advantage is that they are lightweight and waterproof but with no breathability - if you do not want your boat's paint job to fade, it would be best to get another material. Canvas Jon boat covers are a heavier weight than polyester, and also more waterproof. They provide protection from fading and UV damage but they do not breathe so condensation will build up inside the cover - which can lead to mildew or mold. If you get canvas models then it is best if your boating season lasts less than six months as these products need to be taken off every few weeks for airing out (and because of this, they should only be used with boats that stay in one location all time).

Polyester Jon Boat Covers VS Canvas Jon Boat Covers

Aluminum boat covers usually come in two types: polyester and canvas. The difference between them is that while canvas models are more lightweight, they aren't as durable or waterproof. Polyester models provide great protection from the elements and they also repel water which means that it won't get inside your cover if you're using a polyurethane-coated fabric. But they may not be so breathable - meaning condensation will build up inside it and produce mildew or mold unless you have an air vent on top of the cover (which helps prevent this). Canvas models don't offer as much protection because they are lighter in weight but the canvas is stronger than cotton cloth and better at resisting damage by UV light.

What is the best material for aluminum boat cover?

It depends on the size of your Jon boat. If you are looking for a model that is easy to store and remove, then go with a lightweight slipcover because it can be stored more easily than its heavier counterparts.

They are heavy and expensive but will protect your Jon boat from everything the elements can throw at it. Tip: Good model should be big enough to cover both sides of the boat.

Is flat bottom boat cover worth it?

These bags are often made from the same materials as the actual boat cover to provide maximum protection and minimization of material wear and tear.

The attached carry-bag is just as sturdy as the cover itself - but carelessly storing can lead to damage such as from animal scratches or pest infestation.
