This just seems way more trouble than it's worth. I'm sure it corners great. Unless they're also towing a 2nd boat, I can't see the point of this.
Correct Craft used to make a tandem boat trailer for delivery to dealers. There was a pic of it but I can't find it now.
I'm a Correct Craft owner but appreciate all inboards and there's some great information on this site!
