I can vouch for the performance of the Norfolk Lake in gale force winds! We camped on the South coast just before Easter on the day that all cross channel ferries were halted! We were prepared with a few extra guys and delta's all round, and and the NL held firm no problem, which is more than I can say for 4 or 5 of the caravan awnings that were flying around the site!

I can imagine that more lightweight tunnels would be vunerable in high winds, but the added weight of the canvas, strong poles, and that all important horizontal cross brace means that the NL (and BL's) perform really well!

The ideal position for a tent guy is at the top of the tent, for a tent that as a multiple pole system.

The top is the ideal position on a ridge tent but not on a tunnel tent.

The poles of a tunnel tent are designed to flex, if they cannot flex they will break.  The loading should be equally supported around the hoop in order to allow the required movement and to retain the integrity of the structure.

Your idea of a net would not provide any support to the top of the tent.  Support cannot be transmitted around a curved pole to the top of the tent.  It would provide a certain amount of support to the pole at the point at which the guy left the arc of the hoop, provided that it was fixed to prevent it sliding around the hoop, but there would normally be a guy attached close to that point anyway.

I agree Bertie, I don't think the net would add any stabilty beyond the possibility of in effect, raising the guying points.

At first though the idea of the net might suggest that it would help maintain the integrity of the shape of the dome.  Unfortunatly the loss of shape in real world conditions is from inward bowing of the side of the structure.  The net could only resist outward bowing, might be good for a bouncy castle.  :)

........... Good afternoon everyone.

Next year ( still at planning stage), I shall be camping in Wales for a month at Glyn Y Mul Farm, near Neath using 2 very large ex-army ridge tents plus other um, bits of canvas.  The wind factor obviously is of a major concern.

I've recently been in touch, however, with old Sir Frank Beaufort (via the Ouija board) and he recommended to me that apart from employing the usual storm guys, erecting good quality wind-breaks (the ones with guys and pegs) and angle them so that when the gale hits them they will deflect the said gale up over and Bob's your Uncle.  Sir Frank further advises to use storm guys on the wind-breaks too!

I had the timerity to ask him whether he knows what he's on about and he told me to eff off!

hiya rex,

the pole lengh ways is a good idea alot of the newer ones have these,my old faithful outwell everest tunnel does not but few years ago in trearder bay we woke to the top of the tent bent that much that the pole was touching our pillows we nearly died but sat it out and oh went round and tightened all the ropes etc and the next morning it was torrential rain and storms.But im planning on going away in our little tunnel next bank holiday as oh cant get friday off so not attempting pitchiong my georgia for 3 nights at 9pm at night.

My tunnel tent i trust far more than brand new georgia.
