An outstanding example of this go-anywhere blue water cruiser. Designed with long distance sailing and adventure in mind, this extremely seaworthy boat will take you throughout the world in safety and comfort. Having had thousands spent on her by the current owner in the last few years and a full professional refit in 2017 including new rigging, new decks and a full engine overhaul, Agnes Blue is ready for her next adventure, wherever in the world that may be. Her hugely generous accommodation provides an abundance of space and light and will put many much larger yachts to shame. Viewing comes highly recommended to truly understand the capabilities of this boat.

The accommodation is a particular feature of this boat with excellent standing headroom throughout the vessel and all refreshed, including brand new carpets in 2019. The Cabins are characterised by solid wood furniture and brass fittings throughout, as well as features like porcelain sinks and chrome taps more akin to a home rather than a boat.

Below decks Agnes Blue is extremely welcoming and cosy and provides a vast amount of accommodation for a vessel of this size. The Wheelhouse/saloon benefits from an abundance of light, and featuring brass light fittings and solid wood furniture, creates a true 'home from home' feel. To port there is large nav station and a good sized pilot berth. To starboard you find the saloon seating area and large saloon table.

Beyond the saloon lies the extremely well proportioned galley comprising large work-surface area and storage, a 2-burner gas oven and grill, twin stainless sinks complete with a chrome mixer tap, a fridge, and a wood burner.

Large double with solid wood furniture and storage .

A proper bathroom abroad! With Porcelain sink and chrome taps, separate shower and sea toilet. All refitted in 2017

Double berth to starboard with more storage.

Single berth modified and refitted in 2017 to create excellent extra sleeping space, plus useful stowage.
