Bruno Corsi's "Yellow Fin" building

32 ft Eclipse catamaran - Woods Design


Building Completion

August 6th 2011

First test at sea
In front of the coast between Ostia and Fiumicino (Rome).

Apparent wind: 8-8,5 kt at 60-65°
Speed: 5,5-7,0 kt

This first exit (still dressed for work) was very exciting  and I found it funny steer with the stick. The first impression, in general, has been quite positive.

Net installation.

Moke-up in pv for the swimming ladder.
Connection completed. If needed the link can be disconnetted quite easily.
Near the hydraulic piston, easily accessible from the cockpit, there is a by-pass valve between the hydraulic piping, for disconnecting the rudder from the hydraulic pump. This make lighter steering with stick or autopilot.
  Moke up in pv, for the connection between the hydraulic piston (linked to the wheel) and the rudder stock.

Since the last update a lot of work have been done for the external surfaces preparation, before the final polyurethane spray painting. The fairing with epoxy filler was really a hard work and, up to 7 coats of plastering and sanding, in some cases was necessary to obtain satisfactory results. After this all external surfaces was painted with two hands of epoxy primer and, after additional work of fine filling and sanding, two final coats of bicomponent polyurethane spray painting  was applied.
After painting, all hatches, portholes and windows was mounted, then actually the boat is completely sealed and watertight.
Also internal finishing work started again and some progresses was made.

The following pictures start from the most recent and go back.

External protection has been finally, partially removed and protection from sun is added. Now it has been really too warm to work under total plastic cover as before.
