Bia 2 is based on a unique boat design created by Andrew Wolstenholme of Norfolk, England, for a special customer. This boat was called Polly. Subtle changes to the lines enabled Andrew to preserve the uniqueness of Polly while producing a copy of her for others to build and enjoy.
During the lofting process, the builder of Bia 2, Dick Stiles, made further changes including the curving of the transom and the aft seat back. This was achieved with multiple marine ply laminates using the vacuum bagging process.
The hull was fabricated from Khaya (Maghony) and Sitka Spruce laminates glued diagonally over a jig. The bulkheads, thwarts and seats were made from marine ply and then match boarded with Khaya laminate. The inwales and forward coaming were made from European Oak while the sole was constructed from Douglas Fir.
The boat is bright finished internally and across the transom, while the hull is painted with two pack epoxy, white below the waterline and red above it.
The original design called for a small diesel engine. Dick elected to power Bia 2 with an electric pod motor driven by a bank of Glass Mat batteries. This arrangement offers some five hours of cruising at about 60% power before a battery recharge is required. Greater endurance is possible if the batteries are depleted further.
Dick made two spoon oars for the boat and rowlocks were fitted. She pulls well with the oarsman or oarswomen sitting on the midships thwarts. As steering is achieved by rudder and tiller, the coxswain can sit in the stern seat and watch the activity midships!
A purpose made Bimini completes the extras added to the boat.
Bia 2 is an ideal tender for a larger boat. She has good sea keeping abilities with her displacement hull and so she can handle open sea, estuary or river conditions equally well.
