Measurement from ground to G21 on boatmate trailer?

[mlsurfco]

Trying to get my new Floe VSD 8000 set up before my 2015 G21 gets here, anyone know how high their bunks are on this lift?

Or if anybody knows the measurement from the ground to the bottom of the G21 (right by the bunks) then I can figure it out that way. Thanks guys!
