One of the ways I prepared for a summer in the Sea of Cortez was to enhance the sun protection and air circulation in our cockpit. We'd been traveling exclusively with the cockpit canvas that came with our Malo 39 some 8 years ago. It is some of the best and sturdiest boat canvas I've ever seen: a spray shield; an overhead cover; and side and rear panels with lots of large, heavy, clear plastic windows that all zip together and tightly fasten to the cockpit coaming all around. It is the type of heavy protective suit of canvas you would expect to come with a Swedish-built boat designed
to sail well in cold, wet, windy weather. Its design allows us to use either the spray shield or overhead section separately; or to zip the side and/or rear panels to the overhead section to partially - or completely - enclose the cockpit. Versatile. In the winters of the Pacific Northwest, the fully deployed cockpit enclosure warmed the cockpit 10-15 degrees above outside temps. It was like being able to create your own floating sun room, and it helped keep us cruising comfortably months longer than we otherwise would have. The photo on the right illustrates the fully-deployed cockpit enclosures on two different Malo yachts, one n front of the other, on a cool, rainy Washington day.
As we've traveled south into much warmer climates we still use the original spray shield (I've only had to re-sew worn-out threads and Velcro so far to keep it going), and we've certainly continued to use the overhead section. However it became impossible to use the rear and side panels due to their lack of ventilation and superior ability to retain heat. As daytime temperatures rose into the 90s we even had trouble with the overhead cover, as the headroom and its attachment points made it feel too enclosed to allow for optimum ventilation while still protecting us from the hot sun. (Another difficulty we'd always experienced with the particular design of the overhead cover, was that it deploys with an aluminum support frame, which restricts our ability to use full rotation on our winch handles when sheeting in a foresail.) We also grew to need sun protection from the rear and side for those times when the sun was lower in the sky but still quite hot. And we expected very hot conditions in the Sea of Cortez.
My criteria for the new hot-sun cockpit shade covers I designed, were:
- Maximize shade.
- Maximize air flow.
- Increase head room at helm.
- Not restrict use of any of our four cockpit winches.
- Not impact use of or access to any of the
crap essential items we have around the stern pulpit, including LifeSling, KISS wind generator, stern anchor, swim ladder, outboard, emergency beacon, outboard hoist, BBQ's propane tank, radar dome, BBQ, fishing rod holder, and boarding gates.
- Not restrict our view.
- Have side and rear panels that could be deployed and removed quickly and safely while at anchor or underway, in any conditions.
My challenges were:
- Unrestricted visibility reduces potential shade protection.
- Unrestricted visibility, and unrestricted use of winches, and unrestricted access to all the stuff we carry 'round our stern, significantly limits the potential attachment points for any shade cover.
After a lot of fretting, I decided on a very simple design that took advantage of the one attachment point I had that met all the criteria: our boat's Targa arch, on which the forward edge of the original overhead cover attached with a long zipper and Velcro. I couldn't take advantage of the zipper on the arch, as the dimensions of my overhead cover didn't match the original's; but I could certainly attach the forward edge of my creation to the arch using the Velcro. And so I did.
I doubt anyone on the Interwebs is interested in the minutiae of how I put this all together, so I'll just say for this post that for the overhead cover, I sewed a trapezoid of Sunbrella with two slashes in the aft portion to accommodate our dual backstays. Note: I spent three days of measuring and re-measuring the depth and location of those two slashes, and I still got them wrong. Sailing is like that sometimes. Anyway, after I fixed the slashie-fiasco, the construction went smoothly. Basically, Overhead Cover Version 1.0 was attached to the boat at its front by Velcro, at the rear corners by grommets & bungees, and in the rear center by webbing loops and shoelace-type cord. I sewed the inner edges of the sides and rear of the overhead cover with Velcro, to accommodate the side and rear shade panels I would soon make. The beauty part of using Velcro, bungees & string is that it makes the cover adjustable up and down according to my - or the weather's -
whim; and it goes up and comes back down very quickly. To illustrate, here's a photo of the cover in place, with the rear bungees and backstay strings tied high on their attachment points. This is the angled-up position we use for light air conditions:
And here's a photo on the left, of the same cover with the rear bungees and backstay strings moved much lower on their attachment points, causing the overhead cover's edges to curve downward like a baseball cap. This is the position we use for windier conditions. With no more than Velcro-and-shoelaces, Overhead Cover Version 1.0 stayed put in forward breezes up to the mid-20 knot range, but could only handle about 17 knots' crosswind before the Velcro along the forward edge parted, starting at whatever corner was windward. I fixed that problem in Version 2.0 by setting a grommet in each corner of the forward edge through which I ran bungees downward to the grab bars on each side of our windscreen. Version 2.0 stayed in place in winds up to 32 knots from any direction. To put up the overhead cover with all its ties and whatnot takes about 4 minutes. To take it down takes less than one minute.
Why, yes, there was a Version 3.0.
Hot sun is all well and good, but hurricane season in the tropics brings lots of rain too. Our first thunderstorm after we returned to Mazatlan showed me that I needed to elevate the center of the overhead cover to allow rain to run off instead of accumulate in the cover's center, creating Lake Sunbrella. To solve the puddling problem I added a webbing loop in the cover's outside center, which I tied to the aft end of our boom to create a slight peak in the cover's center. E-Z.
More soon coming on the side panels.
