Snow Ski sizing vs Floats
Mar 3rd, 2012 at 11:04pm  
I have a good handle on float sizing

but ski sizing - there appears to be differences of opinion
Length of ski vs length prop to rudder hinge and location w.r.t. prop plane of leading edge of ski

Skis are used in two main sizes, which you can shorten / narrow if you wish for your particular installation.

Use the "40 size" ( 3" wide by 14" long) skis on planes from 4# to 7#, you average 25, 40, & light 60 size planes.

Use the "60 size" (4" wide by 15" long) skis on planes from 7# to 12#.
