Gearblog: Geodesic v Tunnel

Geodesic tents are stronger, right? Well maybe not...


Posted: 4 December 2007

If you've always assumed that geodesic tents are tougher than tunnel designs, you might find this interesting.

David Reese was part of Alastair Lee's team filming footage for PSYCHE on Skye earlier this year when a storm hit. The day before, the rest of the team had questioned David's choice of a Lightwave T1 Trek tunnel when everyone else was using geodesics.

Ten hours later though and the Lightwave was the only tent left standing and arguably saved the lives of four people.

David describes the 'insanely strong winds with gusts' as 'resembling waves of a tsunami from hell'. Those gusts destroyed two geodesics while the third had to be supported from the inside after one of the poles snapped and tore a hole in the fly-sheet fabric.

You can get some idea of just how bad things got from this YouTube clip filmed from David's tent. Bear in mind that things later got even worse than this...

To be fair, the tent in the clip was around 12 years old and well-used, so the stitching and fabrics would have been weaker than a brand new tent of the same design.

Okay, so it's hardly a scientific study conducted in controlled conditions, but when was the last time you went camping in a lab? There's a school of thought that says while geodesic structures may be more rigid and inherently stronger, in really savage conditions, the ability of a tunnel tent to deform more easily may actually absorb the force of the wind more effectively while a geodesic may fail catastrophically.

Several years ago I survived a savage storm in the Pyrenees, sheltering inside a humble Ultimate Peapod tunnel tent. Pitched side on to the wind direction, the Peapod distorted to the point where it was half its normal height, yet it never actually failed. Meanwhile the campsite around us was littered with the remains of various supposedly stronger tents. Equally, my long-time favourite Macpac Minaret has performed flawlessly in all conditions.

So what am I saying? Not that tunnels are 'better' than geodesics, but that a well-made tunnel design can be extremely effective and that maybe the likes of Macpac, Lightwave and Hilleberg with their preference for tunnels have a point.

We all love our tents (hopefully) each one for different reasons and uses, so lets see why you bought  them? there pros and cons, do you think they are all justified? and who`s got the most?

I`ve got 4, I`ll now try to justify why...

EASYCAMP RIMINI , A roomy 2 person campsite type, bought to get `er indoors, outdoors, lots of room in porch for the kitchen sink etc, and nice windows to watch the rain,and it looks good. One of the glassfibre poles did split, but some glue and tape seems to have sorted it.

NORTHFACE ROCK 22 A good allrounder, like the 2 doors and porches, just the right size for a double airbed, lots of pockets, easy to pitch in 5 mins. A bit too much mesh for cold nights, a bit to heavy at around 3 k for big backtracking trips, although I do take it when `er indoors is dragged along.

WILD COUNTRY ZEPHYR Great little tent, a roomy 1 person, or a friendly 2 (thats why WE bought the rock 22) , must have used it well into 3 figures in all seasons and still going strong, warm in winter with just a small  part meshed, but door can be unzipped to mesh only, if required. Similar size new models are a fair bit lighter.

MOUNTAIN EQUIPTMENT AR ULTRALIGHT 2 my latest purchase 2 weeks ago (after sending  a Mountain hardware airjet 2 back with vent design faults) took it on 2 bothy trips to Scotland (just in case) last week, but did not use it ( slept in bothies) so have not tested it out yet, like the low weight, my only niggle is why is`nt it tape seamed  as standard,  I ve applied  the silicon sealer, which was a bit of a drag, so I`ll have to see how waterproof it is the hard way.

So thats my lot up to now, Although  I`m thinking now of a 4 season semi/ geodosic tent now, almost bought a Northface tadpole 23DL in blacks sale in Keswick on Friday (£179 I think) but there was to much mesh for 4 season, so I`ll keep looking.

One tent's enough for anyone. I bought an old Hilleberg Naik because my cotton Vango Force 10 wasn't really doing it for me anymore. The Naik's main features are being very easy to pitch and collecting condensation for a hobby. Actually that's not quite fair, it's also has a very small footprint, so it's good for ledges and other places that aren't too roomy. It seems to be good at not collapsing in storms, but it shakes a good deal and keeps you awake.

My next tent will be self pitching and only weigh .5Kg, because I'll buy it in 2032 when I've finished paying off the mortgage
