Bergstrom's boat is one of the more complex. He uses the smallest blocks and lines he can.
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
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.
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
Ebbe Rosen/Olle Wenrup's boat, working aft from the previous image.
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.

Simple jib sheeting on a Rondar. I think this is a Rondar (look at the thwart). This system is typical of the Australians and many Europeans. Note that the track is angled such that the lead moves forward as it moves outboard. Also note that the track is raised on a post at the inboard end.
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.
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 boat has the standard Waterat fore-and-aft jib lead tracks that I am very used to, but also has a barber hauler to pull the lead out. Note that the barberhauler pulls the lead forward (or down) as it pulls it outboard. A light shockcord pulls the floating barberhauler block down to a Ronstan cheek block mounted above the jib cleating platform. This does not alter jib lead angle, but prevents the barberhauler block from getting tangled on something, or from scarring the finish on the seat tank.
On most Waterats, the shroud system is in front of the diagonal bulkheads. You can see the shroud extension emerging from a tube in the seat tank, forward and slightly above the jib cleating platform. It runs through a slot in the bulkhead, to a triple wire block. A wire tackle runs between that triple block and a 2nd fastened on the mast step. The wire comes off the tackle and is turned to run aft along the base of the centerboard trunk. The wires from both shrouds run down the same side of the centerboard trunk, are combined, and deadended on a double block with a rope tackle. On 7200, this rope (line?) is run to both seat tanks, so that the shrouds (and the forestay) are adjustable on the seat tank rather than close to centerline on an aft thwart as on most Waterats.
7200 does not have a forward thwart.
7200 ready to launch.7200 can sail as a forward tack, spinnaker bag boat, or
can move the forestay behind the launcher and sail as a conventional spinnaker launcher boat.
