l'Oiseau Bleu (Blue Bird)
The aim of Oiseau Bleu is cruising, but real sailing cruising.
You can spend the day pulling on the ropes on top deck, with interesting sailing performances, and have a comfortable
cabin and saloon for your night.
It could present some interest in active or sport charter in West Indies I think, with sailors interested in sailing
big boats with a deck arrangement close to racing maxis, but with all comfort at anchorage.
The internal arrangement is as follows :
- Fwd deck dedicated to anchoring purposes. Furler is fitted for genoa
- Middle deck is a sun deck. Winches and piano at mast foot
- Aft deck is for sailors : helm, winches for main sails and genoa, and at the aft a small deck saloon under the mizzen.
- Fwd cabin is owner's suite, with panoramic portholes on ship sides and top windows oriented fwd to give more natural lighting.
- VIP cabins can be located in the middle, with a porthole for each of them, and we can make 2 or 3 of them each side of the ship.
- Aft part is dedicated to galley and wardroom, sheltered under the superstructure.
- Aft deck can be used as sun deck and/or for storage of tender(s).
- You can reach top deck by 3 stairs : one each side giving access inside the "deck house" in front of the helms, and one at the back on portside giving direct access to deck saloon.
There is enought space for a lower deck, in the middle section - can be used for crew quarters and technical rooms (engine room, cold room, technical facilities, etc...).
From performance point of view, Oiseau Bleu can look simple but her design is not.
I designed a sort of "dynamic" hull, using a deep hard chine. This has nothing to do with what we can find in Open
racing boats because they are not used to reduced the real breadth of the ship and increase virtually the power, but
for hydrodynamic lift.
Waterlines screenshots at different heel angles, to illustrate the principle :
- From 0° to 15°, waterlines are typical for hardchine hull, but nothing special.
- At 20° and 25°, you can see waterlines looking like a lifting body, giving a real lift to help the ship increasing VMG and heading capacities.
- At 30° and 35°, lines are changing to neutral, to not affect ship handling when sailing conditions become more difficult.
This hull can provide a very good 'grip' upwind, and this allows to reduce appendage wetted area. With a semi-long keel
and winglets, I'm confident in ship performances upwind.
The design is still under development.
