The interior of the Willem Jacob is a spacious and well lit accommodation. It has been designed by Welmoed Bogers. During winter 2010/2011 the interior has been expanded with an additional multifunctional space, which can be used as dormitory. However, without sleeping accomodations a mainhold can be realized of 50 square meters.
The former cargo hold is nowadays available for guests. With benches alongside, additional seatings and tables, meetings and diners with sufficient seating are possible, as well as gatherings or presentations. In case of smaller groups or wishes of multiple spaces there is a removable wall which divides the mainhold in 2 large rooms.
Along portside and starbord side comfortable and ergonomic benches are fixed. In front of the benches there are several several moveable tables and additional benches. The complete interior can be fixated when sailing. The maximum seating capacity in the dayhold is 40 guests. We have a comprehensive library in the dayhold, containing books on sailing and shipping. In the ceiling there are several large windows which allow daylight to enter abundantly and which provide a below deck view of the mast and sails. Amidst of the dayhold a fireplace is built, which offers a beautiful sight and comfort. The ship is heated with radiators during the day, but to conclude a great day of sailing, the fireplace is often lit afterwards.
