BlackCat Mark II

[FJRpilot]

Those nasty seam allowances are always tricky. That is the truth.

My current tarp is 11'. I have heard that if your tarp is too long, it can mess with hammock suspension and that would not be fun. I am not super tall, so my vertical reach on a tree can only go up so high.

I guess I'll just do whatever BB tells me to do. I'm going to trust the expert with his design.

Good call... I've always looked at BB as one of the "Mage's" of Hammock camping. I still have the PDF of his build instructions for the original "BlackCat".... It still available online...

Do you have the spreadsheet? That seems to have been lost in the interweb.

All the tarps I made were from BlackBishops instructions.....https://flic.kr/s/aHsiTZBYun

I'm in the process of reconstructing a proper catenary spreadsheet. It won't follow the instructions exactly (I don't remember how lvleph did all his formatting on the original), but it will give people enough measurements to make one of these.

I actually have copies saved of the original lvleph sheet - a couple different versions. However they seem to be either missing some additional data, or corrupted, as they give errors, and open the excel debugger when you click "feed the cat" to get the calculations.

Edit: here's an older archived thread, that links to a lot of the original files. Most of the links are broken and sites shut down, but a few still work if you take the time to dig through them.

These look sweet! How long did you make your ridgeline?

You are the best! You design it, and I will sew it. Awesome.

Thanks. I will definitely take a look.

One of them kept morphing....ended up being my Winter tarp.

My OldManWinter has a 13' RL... No trouble with my suspension, but the bottom edges are a bit higher off the ground when closed down in storm mode...
I'm summer, You also don't need to pitch it super low, because the extra length gives you more coverage. For winter is though, you want more interior space.

I think for a winter tarp, 13' RL is a great length, but if I was to make one, I'd make it wider to match as well. I'd start my design with the doors because they define the height, pitch, and width of the final tarp, important factors for dealing with snow load.
