18 ft skiffs. It had a crew of two rather than the usual three which made sailing the boat difficult when handling the spinnaker pole and its complex wire bracing. It was this complexity that made

Up until then, 18ft skiffs carried as much sail area as possible which them spectacular to watch but difficult and expensive to sail. These incremental improvements resulted in what Frank called “the end of the big boat era.” In 1997 this simpler, faster design was made the standard for all 18ft

In 2012, ISAF held trials for a women's high performance boat to race at the
Olympics. Bethwaite submitted the 29erXX, a souped up 29er with bigger sails. Although this boat lost out, the winning entry, the 49erFX from Mackay Boats (which developed a new mast and suit of sails) does feature
518:
Skiffs would raise the centerboard at times for more speed. This made spinnaker sets and drops more difficult. With better acceleration through tacks and jibes, the centreboard size could be reduced which eliminated the need to raise it, so the extra space made tacking and jibing even
534:
The shorter mast, shorter pole, smaller foils, and smaller sails reduced the loads on the boat, which resulted in lighter boats, and a lighter crew weight to control them. This meant that the boats could point higher without losing
514:
Maintaining at least 7 knots through the manoeuvre meant that large rudders were no longer needed, so they were reduced in size, had a more of a slab design found in commercial planes, lower drag, and a more balanced
468:. The Olympic committee selected the 49er. From the 2000 Olympics and onwards, the 49er sailed with country flag designs covering the entire spinnaker, making it clear which boat was which.
528:
As a result, the spinnaker pole length was reduced which moved the center of effort back. This made the boat more balanced and easier to steer, so the rudder had less drag in the water.
525:
The increased speed made the spinnaker more sensitive to changes in the wind pressure and strength, so the spinnaker could now be smaller and flatter, resulting in even more speed.
505:
GPS data highlighted a needed improvement then tacking and jibing because the speed dropped from 14-15 knots to 2-3 knots, mainly because the crew had to stop to re-sheet the jib.

The annual cost (1986) of an 18ft skiff was $ 120,000, and this high price had a negative impact on the sport, so Julian “consumerised” his Prime Mk3 to create the B18.
495:
Julian continues his father Frank’s pioneering designs in a similar manner – constant improvements looking for more speed from simplified designs. Here’s one example:
453:
Prime Mk3 was also made of balsa wood, had a wingspan of 26 ft, and weighed just 99 pounds (45kgs). This was later used to make a plug for the standardized

The crew was now able to run from side to side without stopping so the skipper could turn the boat faster. This enabled faster and deeper, and tacks and gybes.

The enormous loads from the boom vang required a “ram-strut” in front of the mast. This worked well but prevented a self-tacking jib.
