It is identical to the Essential, the difference being: it is not custom-made, it varies in increments of 50 cm. To ensure it still fits the size you need, we have sewn the tack point a little higher, allowing for adjustment. The excess fabric can be rolled and secured on the roller.

To order, it's very easy:
- Choose the size corresponding to your luff length (if you do not know it, I am able to provide you with the theoretical value for your boat)
- Choose the circumference at the listening point among 3 possibilities (38 or 48 or 58 cm)
You receive your Genoa sail cover ready to install. (for example, your luff measures ...) 13.30ml, Order the size 13.50ml)
To take care of your zipper, We recommend tying a bungee cord between the slider body (and not through the zipper pull hole, see illustration photo) and the balcony, for example, which will help absorb the tension on the zipper.
Let us now discuss the marine canvas that we have selected. For the manufacturing of our genoa covers. This high-quality American material offers a multitude of advantages.
- It is breathable, which means it can expel water from the inside to the outside, but this property only activates in the presence of a force such as sunlight or an artificial heat source, thus raising the temperature inside the cover compared to the outside.
- Its tear resistance is remarkable, making it a durable and reliable choice.
- It is also waterproof or water-resistant. Although the seams may leak for a while, these leaks are usually temporary until dirt clogs the needle holes. In case of heavy rain, leaks may occur due to the spray effect, which is attributable to the lack of a polyurethane coating on the fabric, making the material more breathable.
- A DWR (Durable Water Repellent) coating is applied on both sides, creating a water-beading effect. However, this feature fades over time and can be reapplied. It is important to note that this does not affect the fabric's inherent water resistance. Additionally, to prevent mold formation, an antifungal agent is also applied.
Maintenance of this nautical fabric is simple and effective:
- Clean locally using a soapy solution made of a mild detergent and warm water.
- Rinse thoroughly with clean water to remove the soap, then let air dry.
- In case of mold stains, prepare a solution with one (1) cup of bleach and half (1/2) cup of mild detergent for 4 liters of water.
