2006 Quayline 18

Burnham-on-Crouch, United Kingdom


The Quayline 18 is a highly regarded compact cabin cruiser, based on the very popular Sealine 18 but with a more modern finish. Ideal for trailer boating due to their relatively light weight and dimensions, they make a very comfortable alternative to boats like the Quicksilver 550. St Jacks is a rare diesel powered version fitted with a Volvo Penta D3-130 offering a great combination of performance and economy. Her impressive inventory includes a galvanised road trailer, trim tabs, full canopy and tonneau, fridge, GPS chart plotter and more, all presented in superb condition for her age.

Additional Comments

St Jacks has had three owners since new and has clearly been very carefully kept and lightly used. She is a rare inboard diesel version which was specified from factory with almost every option available (original invoices, order form and brochure on file). For much of her life she has been dry sailed rather than living afloat so her drivetrain and general condition are far better than many younger boats.
