Lewmar portholes and hatches are synonymous with quality and reliability in the marine world. If you're looking for spares for your Lewmar boat porthole or marine hatch, you've come to the right place. We offer a selection of models, from Low Profile to Flush, to perfectly suit any type of boat.

A watertight seal is essential for comfort and safety on board. That's why it's crucial to use genuine Lewmar spares. Our seals and handles are designed to withstand the elements and marine corrosion, ensuring long life.

Fixed, opening, and sliding boat portholes and marine hatches are available. Opening models offer excellent ventilation, while sliding ones are ideal for tight spaces. Before ordering, carefully check the measurements of your boat porthole or marine hatch to ensure compatibility.

Why Choose Genuine Lewmar Spares?

Using compatible spares may seem like an economical solution, but it often turns out to be a mistake. Non-original spares can compromise the watertight integrity and lifespan of your boat porthole or marine hatch. With genuine Lewmar spares, you're assured of a product tested and approved by experts.

The Officina Basile Tip

Maintaining your boat portholes and marine hatches is essential to prevent leaks and structural damage. Regularly check the seals and handles, and replace them if necessary. A small investment in maintenance can avoid costly repairs in the future.

• Fast shipping throughout Italy.


• Warranty on genuine Lewmar spares.

If you also need to replace the screws, we recommend always using AISI 316 stainless steel screws to resist corrosion. And if you need to seal the boat porthole, use only specific marine-grade sealant. Also, check out the section dedicated to windshield wipers if you need perfect visibility.
