This is our special and original 420 Top Cover. We have made this from scratch in-house: from carefully selecting the materials, scanning and developing designs to manufacturing it. The top cover will protect the hull and rigging from the sun and keep its interior dry.

Note: The image may be slightly different from the actual product. ROBSHIP is always working on product improvement and those improvements are reflected on the products as needed. On the website, we differentiate products with “MK numbers”. We also update information on the products on this page as well. However, changes that do not affect the product’s efficiency may not be reflected in the images.

To produce this top cover, we 3D-scanned the boat, created a model based on that, and designed panels by using the CAD software. Because of this, we can now create panel layouts that even fit the curves of the boat well. Depending on the builder there are small differences in shape, design and placment of cleats etc. However this cover fits all builder's boat's well in our experience.

We have a slot built in so that you can secure the ropes while keeping the cover on. Also, to make it possible to put the covers on even during forestay, you can fully split the tip of the cover with an open zipper. Not only the bow, but all zippers have a waterproof tarpaulin inner-flap on the back side. This not only prevents the contact of the hard zipper and the hull, but also functions as a gutter. The flap prevents the water infiltrating through the zippers, and leads the water down.

To cover the sidestay, the side panel comes with a slit which has detachable buckles. This buckle and belt is connected with a rope that runs through the side panel. Since the tension goes in the side panel, it doesn’t flap. We placed backing materials on buckles that touch the hull. The panel on the stern runs under the hull and zips closed on each side for a superior fit.

Because we have designed a slit with a zipper from the sidestay chain plate to the mast, you can put on the cover even while the mast is up. The joints of both the mast and sidestay are covered with a cone-shaped cover. By tightening it with buckles, you can minimize the size of hole around the stays and cinch tight to the mast. The stay, mast, and cam that touch the fittings are strengthened with abrasion-resistant patches. This prevents the cover from being damaged. There is a pull tag over the cockpit to pull the cover up to the boom or with the halyard so water doesn’t accumulate over the cockpit.
