Seaward 23



23.3 feet





We are pleased to offer for sale this Seaward 23. These boats make great day boats and good overnighters as well as being perfectly suited for longer holidays in marinas whilst you do a spot of coastal hopping. This size of Seaward is popular with young families and couples alike and this actual boat is a unique, single engine, stern drive version of this remarkable craft – it was first owned by a Seaward employee, and it was finished to his specification – so there will not be another quite the same. Her size belies her amazing sea-keeping qualities - these Seaward 23’s are well-known for being capable coastal cruisers with Channel crossing potential. ‘Woden’ has been regularly maintained and well looked after by her present owners, please see below for details of her recent service and maintenance history.
