Since the distance is short, this boat would only be used at low speeds.
The big reason for it is that the beach is so flat that there will be 10 -
20 feet of water between the water's edge and the trailer when it is deep
enough for a trailer boat to float on or off. That makes launching and
recovery a real pain in cold Maine water. Also, getting a boat on and off
when there is a small surf running is difficult.

I believe the Brits have a boat beach dolly that fits right into a road
trailer for applications like yours. That way the road trailer avoids the
salt water and the dolly/boat is light enough to wrangle by hand. Get the
fat dolly tires for soft sand.
