I'm located in Michigan and I recently sold a Precision 23 to a couple from Florida. They were both engineers of some sort, and were both a bit on the OCD and weird side (who knows what they thought of me, eh?).
As much as they analyzed and fussed over stuff that didn't matter at all, they were perfectly content to haul the boat from Michigan to Florida without any tie-downs. Keel or no keel, I'd hate to think of the forces involved in an emergency maneuver at expressway speeds.
Although I was hoping to never hear from them again, a couple days after their departure they sent me a picture of the boat on it's trailer in front of their home. Where engineering fails, good luck triumphs.
