Description
The winter cover for the Valiant 520 rigid inflatable boat is an essential piece of equipment to protect your boat from bad weather, UV rays, and dirt during the winter months or when it is not used for an extended period.
Since it is easy to handle, you can also put it back on between launches during the season.
The boat cover made by SNA is made from a high-quality marine material, composed of polyester coated with PVC on both sides and lightweight, 325g/m², which is half the weight of a truck tarp. The color is gray.
The cover protects the entire boat, from the front (the bow roller which remains accessible in 95% of our covers) to the transom, excluding the engine so that it can be fully raised. You will find covers to protect your outboard motor on our website.
The tarp is attached to the float's fender (also called the anti-chafing strip, it absorbs shocks so that the float is not in direct contact) by hooks held together with a bungee cord. For balanced fastening, the bungee cord (thick elastic) passes through eyelets distributed all around the tarp's perimeter. To prevent the stainless steel eyelets from contacting the float, we sew a PVC flap underneath the eyelets. The plastic hooks attach to the gutter located underneath the fender. For all fastening details, please refer to our video installation tutorial.
You will notice that installing the boat cover requires no drilling.
We use all the natural attachment points already present on your inflatable boat.
The cover made for you after your order is a custom-made cover, meaning that it takes into account the specific features of your Valiant 520 boat.
We check the position of the console when it is bolted, the presence of a bimini, a roll-bar, railings...
For example, the position of the console when it is not molded must be confirmed with a measurement form that we send you after your order or that you can fill out immediately by downloading it.
The bimini and roll-bar options must be indicated by selecting the option when adding the product to your cart. There is also a measurement form to fill out so that we can plan the necessary openings for the roll-bar legs.
We anticipate everything as much as possible so that you are fully satisfied with your purchase.
The boat cover is equipped with a vent to ensure ventilation under the cover.
All seams are made with UV-resistant sail thread, which ensures very long durability for the covers.
The cover is delivered to you in a bag.
The boat cover will help you reduce maintenance and repair costs in the long term while allowing you to spend more time enjoying your leisure activities.
Please note that this full cover must be removed before driving on the road.
During the boating season, it is also useful to have console and seat covers that you put on each evening instead of using the mooring cover.
Finally, you can be reassured by the exceptional quality of our boat cover, also commonly called a mooring cover, even though it is more difficult to install when the boat is in the water. Manufactured by our company SNA in Morbihan, which has been your trusted partner in marine protection for 13 years.
