Prima is a classic cruising yacht designed for comfortable cruising in any weather. She has been constructed to Lloyds standards using traditional methods ensuring that she will provide safety and enjoyment for generations of sailors.

As a member of the Harrison Butler catalogue, she has a design pedigree recognised around the world for ease of handling and seaworthiness.

This long admired design has received much attention for the beauty of her lines and will be a show piece for whomever owns her.

Prima is a speculation build and we are currently seeking a buyer. At this stage the buyer has the oportunity to customize the interior accomodation to suit. If you are interested in discussing terms of purchase, please contact us.
Background:

In 1937 at age 19, Joan Jardine-Brown (nee. Butler) set about designing her first, and sadly, last yacht. As the daughter of T. Harrison Butler, himself a prolific and award-winning yacht designer, Joan was well prepared for the task. Using her father's working method Joan produced Prima, a metacentrically balanced hull, with some of the most beautiful lines ever seen in a cruising yacht.

Harrison Butler was one if the great champions of metacentric analysis, which he used as a tool to create hull forms that are legendary for for their ability to easily hold a course at any degree of heel. His boats have a reputation of being easy on the helm, sea-kindly, seaworthy and comfortable.

Long believed to be the most beautiful boat in the Butler catalogue, we decided to take on Prima as a speculation project. She will be the first Prima built in the UK and Joan, now in her eighties, is eagerly anticipating her launch date.

Construction:

Hull - Carvel planked in khaya (African Mahogany) over steamed oak frames and fastened with copper rivets and bronze screws. The plank seams are caulked with cotton and will be paid up with lead putty.

Backbone - The stem, stern knee and floors are laminated iroko. Laminating these curves is the only non-traditional aspect of the build and was introduced because of the strength advantage of lamination over solid timber. The iroko backbone carries a 1100 kg lead ballast keel, which is bedded and fastened to the hull using bronze bolts.

Deck - The deck beams are traditionally joined out of carefully selected khaya and fastened with bronze screws. The deck substrate will be marine ply, sheathed in fibreglass and given a textured canvas-like finish.

Accommodation - The accommodation plan was completed by T. Harrison Butler himself and is typical of his catalogue, which places simplicity, usability, and durability as the highest priorities. The result is a functional and comfortable cabin with well thought out stowage and accommodation areas. We recognise that this classic interior may not suit some modern sailors, therefore we look forward to working with the owner to refine the plan as required.
