I've been cluttering @gamemaster84 thread for too long so I've started this one to try and hash a design out.
I wasn't planning on making another shelter but reading @WilliamC plans for a minimalist 2p mountain worthy shelter, and rsbtr having some seconds cuben 0.5oz on sale soured me on, and I'm furlow for another couple of weeks.
The design criteria are,
-Under 340g
-Able to handle moderate wind
-More spacious than my tramplite
-tarp only or single skin
- maximizes the 6 meters of cuben I've ordered.
I'd like it to be under 340g as that's the weight of my tramplite and myog duplex tarp.
It needs to be between these for most things, wind resistance, space etc if it doesn't do anything better than either of them it won't get used!
The simpler the better too, more chance of it not ending up as offcuts.
Zpacks are masters of maximising the use of cuben's fabric width in their designs, but I don't want to use the hexamid method of using tie outs to make the shape, I prefer seperate panels. And minimum number of stakes too.
6 meters isn't a huge amount but I think I can meet my criteria with it.
The dimensions of the tramplite ridge are 186 long by 125 at the apex, my duplex copy is 3m X 125.
These both provide enough headroom for me, but more is of course better. It's this that causes most of the head scratching!
I'd like to make it as slippery to wind as practical as it's being made of 0.51 cuben, so I'd like to keep the ridge hight minimised whilst maintaining an increase in livability over my tramplite.
My duplex is more than enough with its duel pole ridge, so if I go for two poles I might choose a 115-120cm pole length, the single pole tramp is just enough at 125, and that's with a gently sloping 147cm rear panel.
Currently I'm playing about with a duel pole design that uses a roof made with 2m of cuben cut lengthwise to make a 4m strip of 137/2 minus seam allowance so about 66cm assuming 25mm tape to make the seams.
4 meters makes a ridge 3meters wide 125cm high.
Head room difference between 115cm and 125cm ridge hight keeping the length constant at 3m is 386 v's 420mm,
The tramplite for comparison at 1m from the centre (my reference is a 2m tall person, I'm 176) is 382mm and 964mm wide.
Ridge hight is a compromise with wind resistance, I'm hoping those with more experience than me of bad weather in different shelters can give me their advice here?
115 wouldn't be any better than the tramplite, but 125 would also add complexity to the door panels, 134cm at a gentle angle won't hit the floor, not much of s problem at the entrance, I like the venting there, but I'd like the opposite side to get to the deck.
Here's another idea to try and increase headroom. Potentially minimises stakes, but I would prefer not to have any additional struts. Might be doable with just a top and bottom guyout? Also makes the door panels messy.
I'm not wedded to any designed, so if you lot have any ideas I'd be very happy to hear them!
