Sorted now gents.
Took the ski on a lake near me and no issues.
Spoke to the launch ramp at Penzance, very helpful lady, jet skiís welcome and parking etc available, seems pretty relaxed only requires ins and life vests. Will have a ride down to lands end and see what we can see.
Just hope the Mrs doesnít spot the ski hooked up to the car when we leave as I am
Yet to tell her
