Trailer Sailer Towing

I have recently purchased a small trailer sailer, boat length 17′ 0″ The previous owner had the mast unstepped and laid on top of the boat with approximately equal lengths overhanging front and back. The mast is about 25′ 0″. Is there any reason I can’t trail the boat with the mast lowered but still stepped in the tabernacle? Obviously the mast would overhang the rear of the boat by about 15′ 0″ with this arrangement. I can find nothing in the towing regulations against this.

Many thanks Mike Marshall
