Here’s the plan
For trailing, we’ll use the main mast as a ridge pole. In the yard, we’ll suspend the cover from the halyards. I sent this sketch of to Acorn Canvas to get an expert opinion. They approved and I ordered: acrylic canvas; webbing; eyelets; shock cord; and thread.
Putting it together
I ‘offered up’ the fabric to the boat several times in the course of making the cover, marking with tailor’s chalk before bringing it home to cut and sew each stage. Domestic sewing machine with a heavy duty needle did the job nicely.
Seems to be holding up against the Scottish summer so far.
