The 135' wooden plank-on-frame vessel shown here is modeled after the
traditional privateers of the 19th century, but with a modern sailing hull
shape, ample sail area, and external ballast... a winning combination for
performance under sail.
For an
introduction to our background and experience with a variety of traditional
large wooden vessels, please see our
Phinisi History
web page.
The Privateer as Sail Training Vessel...!
This vessel is being developed for the
Youth Sail Training Foundation
which intends to operate the vessel for the benefit of youths at risk
in California. There are accommodations for 32 trainees, four counselors
and four deck hands forward, and for 10 crew aft.
What better sailing type than the Privateers of
yore to give these young folks an unforgettable experience, and hands-on
training in the myriad skills required to operate a ship such as this.
What have we done to change the original Privateer configuration...? Not that much really!
To create a sail training vessel for 32 trainees has first been a matter of
sizing and arranging the cabins for their intended purpose. Our
next task has been to refine the rather traditional hull type for its new use as a fast sailing vessel,
one that will carry only people and the requisite fuel, water, and supplies,
but no cargo... As a bonus, the refined and more yacht-like hull shape
will provide much greater comfort in the sea than a relatively more boxy
cargo hull type, as well as much greater performance.
Additional goals with this vessel have been to provide maximum strength
for the sake of longevity of structure. Our
aim in so doing has been to reduce maintenance,
improve
the performance under sail, and to increase
the long term safety of the ship.
Power will be provided by an 850 to 1,100 hp Yanmar diesel. The
target top speed under power will be 12
to 13 knots, depending on conditions. Of course a larger engine could
be provided, however above around 12 knots the power requirements and the
consequent fuel use, as well as the machinery cost become excessive.
In other words, we're aiming toward the sweet spot in terms of powering,
rather than top speed...

LAYOUT
The Lines Perspective gives the
best idea of the interior spaces. It is actually the interior layout that drives
the overall vessel size and the exterior configuration. In other
words, regardless of our choice of hull
type, the relative position of the interior and the cabins
will remain the same.
On Deck: At the forward end of the fore deck is a
Cuddy / Bos'n's Locker.
The house structure on the 'midship deck is the Galley. Aft of the
Galley is a raised Poop Deck. Centered in the Poop Deck is a large sky
light. Ladders will lead upward from the Fore Deck to the Poop.
Although it is not shown in the images here, there will be a scuttle
located forward for direct access to the cabins below.
Below Forward: Directly
below the Galley is the Forward Mess area, having 4 Heads, 4
Showers, and 8 berths at that level. Directly aft of the Forward Mess is
the Engine Room Bulkhead. Forward of the Forward Mess is another WT
bulkhead with WT doors leading to another sleeping area.
In the forward Trainee Cabin there will be 32 berths as follows
(starting at the aft end)... 8 + 8 + 6 + 6 + 4. In the aft two bays
there will be 2 berths outboard port and starb'd, plus 4 berths on
center. The next bay forward will have 2 berths outboard port and
starb'd plus 2 berths on center. The next bay forward will have
three berths outboard port and starb'd. The last bay forward will
have two berths outboard, port and starb'd. This arrangement will
allow plenty of room for a companionway scuttle and ladder leading down
at the forward end of this cabin.
Fresh water tanks are located below the Forward Mess. Below the Trainee
Cabin will be a pair of water tanks plus two waste tanks.
Below Aft: Aft of the Engine Room Bulkhead
immediately below the Poop Deck is the Crew
Mess on center, with Crew Cabins outboard and aft. On center above the
Crew Mess is a large skylight.
Aft of the Crew Mess are the Captain's and
Director's cabins.
Machinery Spaces: Directly below the Crew Mess is the Engine Room. The
Engine Room will have
comfortable seating all around the perimeter in order to easily tend the
equipment without requiring full standing headroom. The propulsion engine will be
located toward the forward end. There will be twin generators in-line aft. Fuel tanks will be located
outboard within the Engine Room.
Aft of the Engine Room is a small
storage room for spares, etc.
It is all rather preliminary at this point... and there may yet be
changes to refine the interior, as well as a few
other hull types to investigate...!
The Rig...
The rig will consist of three tubular steel masts, each having a single
tubular steel topmast. The Main Mast and the Mizzen Mast will have fore
and aft Gaff Sails with Gaff Tops'ls. Forward of the Main Mast
will be three Main Stays'ls.
Square courses will be placed on the Fore Mast, though they are not
shown in the above images. There will be two square yards on the
Fore Mast. Above the upper yard will be a Raffee. Between
the yards will be a Square Sail. Below the lower yard will be a
Cro'jack (Cross Jack), which is defined as a triangular sail having the
apex downward.
The Cro'jack sail type has been chosen in order to
allow flying a pair of Genoa-shaped Stuns'ls (Studding Sails) outboard
of the Cro'jack, thus eliminating the need for Stuns'l yards.
The rig thus described is that of a Barquentine.
The mast positions are preliminary, however they fit well with the
interior layout.
