You might try calling Cedar Mills Marina up on Lake Texoma 903-523-4222
- that's where they build Valiant Yachts -they should know all the shippers and you might get lucky with one of their truckers bringing a Valiant up your way and needing a haul back down or coming down here to get one.
sorry to hear about your mom, I've been there with mine. God bless you both.
Try U-SHIP.com - it's like an ebay, but in reverse, and deals with shipping....you might be able to find a boathauler who works with them.
Another thought - doesn't Beneteau manufacture in your area? Contact them, see what they can do.
You might try also seeing if someone will deliver her on her bottom - it's not a bad trip, ICW pretty much all of the way. If I were closer and not ready to take my own boat south for the winter, I'd offer to bring her around to Tampa Bay for you.
