The Ker 33 is an IRC cruiser/racer and sets a new benchmark for this popular division. The boats embody all the talents of Ker Design, along with McConaghy’s unrivaled build quality. The philosophy behind the 33 was to highlight the design, build expertise and techniques that this duo has to offer. Noting the success of the 30-35ft racer/cruisers currently on the market that have been performing on the IRC scene both inshore and offshore, we felt there was clearly the demand for another boat to fit within this category, particularly one with this much potential. The McConaghy Ker 33 is an out and out racing machine optimised for competition under the IRC rating system, with the bonus of surprisingly civilised interior accommodation. At first sight it’s immediately apparent that this boat has been designed for speed – even the stanchions, pushpit and pulpit are of an efficient aerofoil shape. These are of composite construction and autoclaved in house. In addition, much thought has gone into producing an ergonomic deck layout in which friction is kept to an absolute minimum and running rigging led in straight lines, without turning corners, wherever possible. The deck gear package is by Harken, with clutches by Spinlock. Given the pure raceboat treatment on deck, many would expect to find a bare and stripped out interior. Instead, there’s a surprisingly spacious arrangement that’s also well lit, thanks to the trademark big windows and a mostly white finish.
