KSS 46

KSS 46, or one of her larger or smaller sisters, is typical of our standard cruising designs. Space, comfort and seaworthy are the objectives, with efficient sail plan for good average speeds on long passages. Ideal for luxury private yacht or charter yacht. A number of alternative layouts are available to suit number of cabins required. This is 3 or 4 cabins, twin diesel sail drives and efficient rig, with fully battened mainsail and small headsail.

An updated version is built at Ballotta Yacht builders in Peru, and more are in negotiation. A shoe mould will be produced for the below waterline portion of the hulls. Part moulds combine with KSS for even greater efficiency when more than one boat are to be built.

KSS 46 is one of Kelsall's standard cruising catamaran styles, aimed at the long distance cruiser, live-aboard or adapted for charter. The convenience of the accommodation lay-out is of particular importance. Derek has done a lot of sailing in cats around the 40 - 50 foot length. A couple of single cabins with space for a couple of extras to sleep in the saloon when needed is much more practical for the typical crew. A similar view is taken with the layout of the saloon seating round a fixed table.

In the designer's sailing experience the saloon seating is better designed for general use, including the off-watch catnap, rather than something designed for the rare occasion when everyone is sitting down to a formal dinner. L shaped seating works best, with a couple of captains chairs for the occasions when all want to sit round the table.

The 46 began as a 42 footer. When we put the shape into three dimensions we took a second look at the style and decided that some extra length added to the appearance. The only change has been in the overhangs which have been extended at bow and stern. This should compare with most other 42 footers on the market when it comes to cost and space. Our view is that a yacht of this size is a luxury item and to do its job it has to look the part. Obviously, it will cost slightly more in the marina but the extra length will make very little difference during the build stage.
