help launching on sand beach

have a place in mexico, a bit remote. Having a tough time launching the boat (19' SEARAY), been using set of sand rails (12" wide metal planks -each about 10' long) but takes forever to make the 70 yards to the water, any ideas??? Thought about trying to lay doewn some chainlink fence under the truck and trialer for traction. Got to be an easier way!

Hi.
Your not wrong,it's hard & sometimes nearly impossible launching boats,especally a 19 footer like yours,where you have to travel over sand,have you tried letting some air out of the tyres & driving on the sand,however be cautious you don't bog both the Vehicle & Trailer, last resort you might have to go to a smaller Boat.
Good Luck.
