Cosette

A 2004 58ft Alexander Boat Builders 6 berth semi traditional stern narrowboat.

  • £47,500.00
  • 6 Berth

Cosette is a beautiful 58ft semi-traditional stern narrowboat built by Alexander Boatbuilders in 2004. She presents in very good condition and offers a practical, comfortable layout suited to both cruising and extended stays aboard.

Externally, she is finished in a cheerful red livery with navy and cream accents, complemented by a navy cratch cover over the bow deck. She was last blacked in May 2025.

Entering from the stern, the bedroom is fitted with a fixed double bed and benefits from both wardrobe and drawer storage. Forward of this is the bathroom, which includes a shower, corner basin and cassette toilet.

The galley is well arranged with a four-burner gas hob, separate built-in oven, fridge, and sink with drainer. There is ample worktop space and good cupboard storage, making it a practical area for day-to-day use.

Opposite a side hatch is a Pullman-style dinette, which can be converted into an additional double berth when needed. At the bow, the saloon provides a comfortable living space with a sofa that also converts into a double bed, along with a diesel Bubble stove for heating.

Cosette is a very well-presented boat with flexible sleeping arrangements and a layout that makes good use of the available space. She is ready to be enjoyed on the water, whether for leisure cruising or longer periods aboard.

Viewing is highly recommended! To arrange or for any further information, please contact Gayton Marina on 01604 858685.
