my mistake Ron, but I always thought ground clearance was this measurement ie the point in which the hull would ground out. Page 118 in vol.1 of the carrier book shows the measurement from the bottom of the hull ( at the right angle bar that protects the exhaust pipes under the hull) to the ground as being 8" unless i missunderstand its meaning which is very easily possible with my meager brain pan
(PZRwest you want to get these books from Nigel Watson mate absolutely fantastic with more reference shots and schematics than you can shake a track link at !
