tarp coverage

From what I could find all Warbonnet Hammocks have a structural ridgeline of 100 inches. Even if the hammock itself is longer the ridgeline determines how long it really is under the tarp. The Maccat deluxe is 130 inches long so you should be fine. A lot depends on how you pitch it, but I think you have enough coverage even in some real weather.

The XLC has a 110 inch ridge line You still should be dry under a MacCat Deluxe.

In foul weather, you may need to hang this tarp slightly lower to provide enough coverage on the ends, but it should work just fine.

There's a tarp coverage calculator on the right hand side of this page on my website.

It's made for different hammocks and different tarps, but might be helpful for your gear.

Yes, hang your tarp lower if you think you could get wind blown rain/snow.

I am also a big fan of the Warbonnet hammock sock when the weather could be cold/wet/windy.
I set it up ready to use when I hang my hammock, but roll it up and tie it along the ridgeline until I need it.

It helps add warmth, especially in wind, and helps keep spray, splash and snow from getting on you and your puffy layers. You pack up relatively dry gear which saves weight.

It also makes it so you can get by with a smaller/lighter tarp in adverse conditions.
No need to carry a heavier/bulky winter tarp and you can extend the temps of your insulation.

Your experience with a sock may be different than mine, but I consider it one of the best ways to reduce weight. 9 ounces for a Warbonnet Travel Sock saves more weight that you would have to carry with your additional insulation and tarp coverage for adverse weather.
