So my wife and I are planning a bike tour around Nova Scotia for the end of the summer, hoping to make it the better part of a month, towing the dog in a trailer behind us (she's only 35 lbs.) I've been debating shelter types, trying to stay light as we also hope to make one week of our trip a backpacking portion if possible. We usually use hammocks or small tarps, but I am worried about hammocking with a dog, and while I love minimal tarps for shorter trips I'm thinking our experience will be enhanced by eating a few ounces and going roomier. I took my inspiration from Jared Cook's great work on his tarptent for two, and added a few elements of my own.
The finished shelter is kind of a cross between a RayWay tarp and a tarptent for two, weighs about 26oz and gives about 50 sq ft of space inside the netting. I took Shires dimensions and extended the tarp out over the netting another 6 inches or so, moving the drip edge out at minimum 4 inches from the floor. The ridgeline and edges are catenary cut with 4 tie outs per edge. I sewed in mid panel tieouts to act as lifters and provide more interior headroom and stability. There are beaks front and rear, the fron one split in the middle and velcroed to allow easier access. I decided on a center puptent style vertical zipper, so that both occupants have equal access to the door (I know my wife appreciates this). I installed an internal ridgeline to hang clothes, lights, etc. Finally, the netting sides are tall enough to allow about 16 inches of ventilation down the long sides if the weather allows. I still need to design and build a floor, trim up the netting, finish bartacking the tie outs, and sew an organizer for the ridgeline, but it is a nice day and I figured I should take my photos while I can. I shot it set up in a pretty stormworthy pitch, high enough to sit up at the head end but no more. In fair weather I would certainly go higher. I'm eager to hear any ideas you all might have for a floor (anyone have experience with dog claws and silnylon?)
