Winter Cover

Winter Cover Supports

I have a full winter cover for my boat. The high point is at the helmsman seat on the upper deck and from there it slopes down to the rear rail and then down to a cinching strap at the level of the swim grid.

The problem is right at the rear rail. The fabric sags a bit, the water collects a bit, which cause it to sag some more, so it collects more water etc. It very quickly collects a huge amount of water, probably approaching 100 lbs. (Say the equivalent of a 20 liter pail on each side which would be 88 lbs.)

To overcome this problem I made some pads of 1/2″ Starboard, a marine plastic. On the underside of the pads I attached plastic donuts of a thicker material, the supporting rods would go into these donuts. The donut holes were made larger than the supporting rods so the Starboard pads could pivot and take the slope of the cover.
The bases were welded and screwed to pieces of plywood. Under the plywood I put some expanded rubber, the type that is used on boats to keep the plates from sliding off the table. However even this was not enough to keep them from sliding, and thus the upright supports had to be tied in place so the cover would drain properly.

Problem solved. No more ponding water.
 

Rearview Camera

Rear View Camera

Pretty hard to make a case for this indulgence. Call it redundancy, always a good strategy where boats are concerned.
When steering from below, which I do frequently, as soon as it gets a bit rough, I cannot see behind the boat from where I sit to steer. The dingy mounted on the swim grid blocks my view. Thus to get a look behind I have to leave the wheel and go on deck to get a look over the dingy. Then the boat would get off course, quite quickly if it was a little rough, thus the auto pilot was added. However applying the principle of redundancy the camera will eliminate the necessity of going on deck, however if I do have to go on deck I have the auto helm.

I had actually played around with some rearview mirror ideas, none of which worked. Then I came across an article on rear view cameras in DIY Boat Owner magazine.

These cameras are made for RV’s, buses, and vehicles in general so I knew there would be some issues during the install. The magazine article was well researched so I felt confident going with their recommendations. My email with the few questions I had was quickly answered, another good sign. (www.rearviewcamera.net)

The monitor mount that came with the kit was made for vehicles. A ceiling mount of 1/4″ Plexiglas was easily fabricated, attached to the ceiling, and the monitor attached to the mount. No trick here, but doing things like this in plastic sure makes it easy.
The outside camera mount involved a little more work. The kit came with a camera mount to go on a flat surface. A platform for the camera mount was fabricated, that would then attach to the rear rail of the upper deck. The cord from the camera would go into the cabin through a hole drilled in the cabin wall. However the cord from the camera is not very long and if the camera was mounted on top of the rail it was very tight to get it through the hole. Thus I opted for a lowered platform design, which lowered the camera by about 1″, but this was all I needed. For the platform I used 1/2″and 3/4″ cutting board material because that was handy, but I could have used UHMW or Starboard. The upper and lower pieces were grooved out to take the 1″ railing, and then bolted together and then the camera mount attached to the platform. 

Again this was a very easy fabrication. The trick is to think of plastic as an option for dealing with these situations. Drop in and see us!
