safe ice for ice shanty

[wedkarz]

i'm building a portable ice shanty (which can be seen here http://www.iceshanty.com/ice_fishing/index.php?topic=59673.0) and i was wondering what is considered safe ice for this type of shack. i figure it'll end up weighing about 100 lbs. thanks!

Numerous people, single file 3                             7
Snowmobile or Small Car 7.5                              18
Medium Car, 2 1/2 ton Truck 8                           19.5
Large Car, 3 1/2 ton Truck 10                            24.5

Just a guide.

Judging by size/weight I would recommend 5"....since all of your weight will be in a rather small proximity.  5" will support 3 people in that shanty when you have holes near by (holes allow for stress cracking)

5 Inches "at least" of good clear new ice. Especially if your fishing three guys or so outta there.
