Bespoke Manufacturing for Professionals and Private Owners

At Canaldock, we do more than just offer standard weld-on products from stock. We provide portholes, scuttles, windows, and watertight doors designed entirely to your specifications, tailored to your vessel and your most demanding projects.

Whether you are a shipyard or the owner of a barge, houseboat, sailing yacht, or commercial vessel, we support you in meeting your specific requirements with a strong commitment to quality, durability, and aesthetics.

Our portholes, available in weld-on or bolt-on versions with single or double glazing, adapt to all types of projects. From classic brass for a traditional look to stainless steel for optimal robustness, our products meet your technical constraints while ensuring easy maintenance.

From small cabin portholes to large panoramic windows, we guide you through every stage to ensure a reliable and elegant result.
