I use the Gatewood Cape almost exclusively with the SMD Serenity NetTent. I find a pole height of 48" gives me a very taught pitch with the Serenity – tight walls keep the insects from reaching me. I stake out the Serenity tightly with separate stakes, and my pole tip is in the pocket made for it at the apex of the NetTent.
Then I set the Cape harness over the pole tip, (within the Serenity NetTent pocket), and stake everything out. The rear three corners are fairly low, the front two side corners a little higher, but the beak winds up nearly a couple feet off the ground – which I like. I had to add some length to my front guy line. In a sense the whole Cape is tipped from its usual level pitch
This gives me good protection from insects and weather. I don't have to mess with attaching the Serentiy to the inside of the cape harness. (I could never get the mesh walls as taught that way).
Without the NetTent I've pitched my Cape as high as my pole will go. Just add guy length all around. Nice for a midday storm shelter. Actually I rarely bother to change my pole length from 48" now. I simply hike with that length set.
The Serenity NetTent offers several advantages. You have to carry a ground sheet anyway – the Serenity is a minimal ground sheet. The mesh walls help hold in the bedding and other clothing and gear, and keep them from sliding off onto the ground and out from under the shelter. The mesh helps catch some of the mysterious mist that comes down from the inside in heavy rain, and keeps it off me and my bag.
My only quibble is that the SMD Serenity NetTent is slightly wider at the head end than the Cape, so I have to cheat the Cape slightly in the direction of my head to get good storm coverage.
But all in all a great combination. I will never go back.
Corrected: original post confused Serenity with Oasis – my bad.
