Design 2269 - Sirona


Here's a very interesting design that one of our brokers brought to my attention yesterday. It is our attempt at an ultra light displacement "sled" for West Coast racing. There are a couple of notable design features such as the very small amount of rocker in her underbody, her extremely low ballast/displacement ratio (28%) and the location of her engine.

The boat was built of aluminum by Paul Luke of East Boothbay, Maine. She was launched in 1977.

These articles tell the story well. Please double click for zoom.


Here are the plans.


Principal Dimensions
LOA 58'-5"
LWL 46'-0"
Beam 17'-1"
Draft 8'-0"
Displacement 27,330 lbs
Ballast 7,700 lbs
Sail Area 1,470 sq ft

  1. SORC 197?, Saint Pete to Lauderdale Race: Blackaller said, "Come to sunny Florida, sail on this great new boat". The morning of the race there was frost on the lawn. Six waves up from Rebecca Shoals we heard a pop. Five minutes later there was water coming up through the cabin floor. Con Finely sat in the hanging locker and pumped a big whale pump all the way to Lauderdale (at least he was warm). Hauled the boat after the finsh and as the keel came clear of the water, a two wide stream of water gushed from the crack in a weld. The boat was tippy, so they added 16" to the keel by legthening the keel bolts and inserting a spacing structure. Not the finest kind.
