Hull design HOW IT IMPACTS PERFORMANCE

Peter Poland explains how hull design has evolved over the years and how this affects boat handling and accommodation

The search for the ideal family cruiser can be a complicated business at the best of times, especially if you’re looking for a new yacht less than 30ft long. Gone are the days when Jaguar 27s, Maxi 84s and Mirage 28s were widely used by charter companies and private buyers alike. These days, sailors hunting for smaller cruisers have little choice but to

Many conflicting factors are needed to achieve that most elusive of goals – the best compromise between seagoing performance in a full range of weather conditions and maximum living space when in port. I say ‘in port’ because maximum accommodation space when at sea is less relevant. If you are not in the cockpit and sailing, you could be down below cooking (as securely as possible), eating (spilling as little as possible), in the heads (as brie y as possible), navigating (as accurately as possible) or sleeping (as comfortably as possible). The size of the areas used for these tasks is often seen as insignificant compared to how effectively each task can be performed.

Then there’s the small matter of weight. New boats with heavier displacements for their size are rarely seen at boat shows these days for one simple reason: they cost more to build. But that doesn’t mean they are 'out of date. Far from it, because the cruising sailor-whether she or he is looking for massive or moderate amounts of accommodation below-will find a heavier displacement boat with a lower centre of gravity more forgiving and less twitchy to sail than a lighter boat with a voluminous interior.
