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. |

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.

previous images, you can see more of the shockcord takeups. |

This is a Rondar 505. This
system is typical of the Australians and many Europeans. |
 |
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. |
