Order now for Autumn installation

While you’re enjoying Summer, let us worry about (next) Winter now.

Our residential canvas shelters your outdoor spaces from the worst Winter has to offer. Easy to install and remove, our tough cover panels keep wind and rain off your deck, windows or three-season room.

Perfect for seasonal residents or folks with rental properties, too. Learn more and contact us to discuss your project now to ensure we’ll have your panels built and installed before the snow flies.

2023 Award of Excellence

We did it again.

Award-winning complex canvas and solar project from Gemini Marine Canvas and Marine Products.

Our client wanted a full enclosure and matching sail cover with rigid solar panels that didn’t interfere with the boom (and vice versa – solar panels don’t like shade). It took a bit of doing, but John created a frame that gets the panels up and over the boom. It uses our own split side mounts to secure the panels, as well as a host of other hardware and fittings. The canvas looks great, the panels work great, the client is pleased as punch. Problem solved.

The build just won an Award of Excellence from the Advanced Textiles Association Marine Fabricator division. It will be featured in an upcoming edition of Marine Fabricator magazine. We couldn’t be happier.

Not all solar builds are this complex, but if we can do this, we can get solar on your boat, too. Give us a call.
