In my previous post I have detailed how I install cat rigged style sails (Flat Earth Sails for example) onto the deck of my kayaks.
The anchors, cleats and mast base are permanently secured to the deck and require several holes to be drilled through the fibreglass deck to have the bolts secure the items.
Some people cringe at the idea of drilling holes in a brand new kayak especially when experimenting with equipment that they are not familiar with.
My early sail rigs had the cleats mounted too close to where my hand would occasionally brush when paddling in a low angle style.
A few hits of the knuckles on the sharp edges of the cleat made me relocate them and plug the holes left behind by the fasteners.
My friend Jim has not done a lot of kayak sailing before and was unsure if he would like it on his Nordkapp LV.
He decided to minimize the damage that an ill fitting sail rig would do to the deck and devised a system that would keep his deck clean when he did not want to use a sail.
For the mast he used the existing recess where normally a 70P compass would be fitted. He fabricated a base out of fibreglass that has the identical hole location as a compass. He does not use that type of compass but he believes the recess and the complex fibreglass profile of the deck in that area is a very solid location for the mast base. He did not need to reinforce the deck since no flex is detected when the sail is deployed, even in heavy winds.
Jim had to drill holes for the stay anchors; unfortunately a Nordkapp LV does not have perimeter-line anchors suitably located to double as stay anchors.
The rest of the cleats and pulleys (blocks) are mounted on a custom made piece of fibreglass that contours the deck of the kayak.
He simply waxed the deck of his kayak with mould release compound (even grease would work in a pinch) and laid up several layers of glass cloth and resin. Once the laminate cured he padded the underside with a thin layer of closed cell foam to prevent scuffing of the deck and installed the necessary hardware to secure the uphaul and trim the main sheet. He used sections of stainless steel welding rods embedded into the laminate to create guides for his lines but stainless steel saddles could be used as alternative.
His "plate" is held back by a thin line that loops around the coaming of the kayak, and in the front, under the deck bungee cord. The coaming line takes most of the load, the front bungee just keeps the plate close to the deck.
Jim's system can be removed in seconds when he does not use his sail. The base for the mast remains attached up front but there are no cleats and pulleys to clutter his deck.
Owen Walton has sent me these images of his sail set up.
It requires one more stay (back stay) but the sail can rotate freely 360 degrees.
The plastic cleats are low profile.
