Outboard chainplates reduce the loads on the mast and rigging, but to get good windward performance the sheeting angle has to be as small as possible. To right this wrong, bow rollers started protruding forward. In no time there were battle-scarred bows all around the world. Plumb bows and anchors are not good bedfellows, as anchors seem to be as attracted to them as curious hands are to ‘wet paint’ signs. On deck, things weren’t as rosy for the cruising yachtsman. This change has improved performance as the static waterline length and forward buoyancy in the hull have increased. Over the last 15 years bows have become less raked and more vertical. Mast sections and materials became lighter and stronger, enabling rigs to go higher.īy moving the mast forward in the boat, it enabled designers to open up the saloon, and by moving the chainplates outboard and attaching them directly to the hull, eliminated the need for tie rods that eat into accommodation, increasing the feeling of space below while also reducing manufacturing costs. The increase of popularity in cruising, and the lack of rules constraining it, gave designers a free hand. Gone are the stumpy masthead rigs and vast overlapping genoas encouraged by the IOR without penalty, which have been replaced by tall, efficient high aspect ratio rigs. The IOR rules of the 70s did much to determine hull shape, but the demand for more space and accommodation has changed yachts forever. Their popularity has mostly been brought about by modern yacht design and the quest for better accommodation. Older masthead rigs tend to have large overlapping genoas, which are less efficient upwind
