This build almost complete to compliment the Bangkok tug.
Measuring 750mm L x 200mm beam x 100mm depth with laden draft Approx 65 mm.
Mixed ballasting- roof flashing lead, water tank, and two shallow trays of aquarium gravel glued with PVA. Pretty heavy and not too sure if a tad top heavy. Sea trials in late March

The Devon Monsoons abated sufficiently to trial both craft. Full ballasting of lighter over Easter
