The reconstructed boats, shown in yours, were poorly set up to carry a 3 tonne rock. A single hull, with a proper outrigger, would have fared better. The sea journey seems the easier part of the proposed drag. It would have needed calm weather though, and an expert grip on the tides, which Thom assumed was present.
