Bergstrom's shroud system. Starboard shroud detail on Bergstrom's Rondar. Note the tensioning tackle is fastened to the rail. The Australian's do the same, while North American boats tend to have the tackle inside the boat. This approach reduces the load on the rail of the boat, is easy to do - especially as a retrofit to an older boat - and is light.

Bergstrom's spinnaker launcher. Many of the Rondar boats have this tube in the launcher tube. It moves the tack forward and down, and allows the forestay to be extended back into the boat for adjustment.

Note that Bergstrom appears to have a 2:1 block here. This would reduce the compression load on the deck as he tightens the forestay.

Bergstrom's centerboard cap - detail. The Rondar and the Kyrwood have wider centerboard caps, and frequently control lines are lead such that you pull it from either side, with a cleat on the centerboard cap. I believe every control line in Bergstrom's boat is on a shockcord takeup.

Note the absence of a mainsheet jammer; Krister just has a block on the CB cap. He cannot cleat his mainsheet. Bergstrom's boat is one of the more complex. He uses the smallest blocks and lines he can.

Ebbe Rosen/Olle Wenrup's boat, boom end detail. Both this boat - a Waterat - and Bergstrom's had flattening reefs rigged. The outhaul appeard fixed (not adjustable while sailing), and the fittings were used for the flattening reef instead.

The boom is cut to minimum length and uses the standard end fitting, with a small amount of customization. Note the end of the spinnaker pole - many 505s use spinnaker pole launchers.

Rosen/Wenrup jib sheeting. Rosen/Wenrup lead the jib to an aft turning block, and then pull the lead out or down/in.

Ebbe Rosen/Olle Wenrup's boat, jib lead and some control systems. I think the lime striped line coming and going from/to the left (towards the bow) is the jib sheet. Barber haulers control the jib lead angle. Note all the adjustments on the tank, the careful leading of lines, and the extensive use of shockcord takeups.

Moving aft (to the right) of the previous image, you can see more of the control systems. The low thwart to the right of the image center, is the low aft thwart of a Waterat. The solid yellow is all shockcord for takeups.

Jib sheeting detail on 7200. OK! OK! So 7200 (Meller/Mills) were not one of the better boats at the Worlds! I happen to be very partial to this boat, and wanted to throw in a picture or two. Don't you think the oak veneer on the cored tank, and the mahogany elswere is gorgeous?

This is a Rondar. This system is typical of the Australians and many Europeans. Rondar Raceboats have been building successful 505s for over 25 years and are considered the predominant builder.

Their standard boart is a championship winner and features construction with SP Systems epoxy resins with tri-axial cloth. Carbon and Kevlar reinforcement are used extensively in high stress areas and vacuum bag foam sandwich construction is used in deck and hull mouldings.

Check out the trailing edge of the centerboard! The chord is smaller where the CB emerges from the centerboard trunk underneath the boat, than it is just a inch or two below that on the blade.

I think the idea is that the foil is not very efficient next to the bottom of the boat, and why have the drag of a long chord here.... On the other hand it looks neat.

Ian Pinnell's latest Rondar (-98). His cleats on the shelf on the side of the centerboard cap is standard on Rondars.

Pinnell & Bax actually rig the Rondar 505s for the UK market. Pinnell/Nick Powell were 2nd in the 1998 505 European Championship.

This is a Kyrwood. This system is typical of the Australians and many Europeans.
