The Symbol 50' RPH was conceived as
the company's entry level model for the complete line of motor yachts up to 88
feet. This model complements the existing larger raised model versions by
emulating the distinctive flowing profile lines seen in previous 54, 58, 62,
64, 66, and 68ˇ¦ raised pilot houses. We have attempted to create an identity
for the Symbol line by incorporating similar distinctive features in all the
models including the raised pilot houses and the cockpit and flush deck motor
yachts.
The design philosophy I brought to
this design was derived from many years of cruising my own boat. The attempt
was to incorporate features that would not only satisfy my prerequisites but
would be acceptable and appealing to the general boater. In other words, I
tried to place myself wholly in the design and cruise the boat while it was
still on paper. Annoyances such
as lack of storage, head knockers, poor access to equipment, etc. were
eliminated. Attention to ease of handling, vision, height of stair risers,
anchoring, etc and the list goes onˇK.anything that I personally had come up
against was considered and incorporated when possible.
Since the 50'RPH model features an entirely new hull a great amount of preliminary design work was done before the lines were ready to be sent to the test tank at Vizon Scitec's facility at the University of British Columbia. A week of exhaustive testing of the hull model gave proof that we had come up with a winner. The combination of a moderate aft dead-rise, gentle propeller tunnels, a soft entry at the high impact area, aggressive spray knockers and flared bow gave us flying colors in all phases of the tests. We were particularly happy with the performance projections in head seas representative of sea states 2, 3, and 4. The results showed favorable ride characteristics in these normally encountered seas with minimized slamming impacts. Also, it was noted that the ride was very dry due to the bow flair and the wide spray flats.
The interior layout incorporates a
two or three stateroom optional arrangement similar to ones of its bigger
brothers, the 54' and 58'. The up-galley arrangement with raised settee
adjacent to the helm has proven to be very popular on larger models and is
repeated in the 50' model. We have tried to keep an open feeling in the
pilothouse area by utilizing freestanding stairs to the flying bridge and
leaving the space behind them open to the salon. We did not eliminate the port
side door to the side deck, so often seen on other competitorˇ¦s models to
maximize the settee. This decision was made for functionality reasons, keeping in
mind the operatorˇ¦s quick access to either side deck without having to walk
completely around the forward truck cabin.
The sizes of the salon and cockpit
area have been balanced to provide maximum space to both.
The windows in the salon are positioned to give maximum light inside
the boat and the sightlines, for both sitting and standing, have been
carefully laid out to eliminate any straining of the neck or ducking of the
head to see out. The flying bridge, accessible both from the pilothouse and
the cockpit, provides a comfortable area for both lounging and running the
boat in good weather. The helm area is raised giving an excellent sight line
over the bow and standing space for optional docking stations is provided to
both port and starboard.
While we don't specify any particular
engine manufacturer for this model the standard horsepower range for engines
are from 700 to 800 BHP giving speeds in the mid to upper 20 knot range
depending of various loading conditions. The underwater exhaust system should
insure that the boat is relatively quiet and free from trailing exhaust fumes.
The rudders are foil shaped and oversized to insure good tracking and
responsive turning ability at both low and high speeds. The keel depth has
been kept to a minimum for reduced drag while still providing major
longitudinal strength and directional stability.
As has all other Symbol models the
hull is solid laminate on the keel and bottom up to the chine and then cored
with cross-linked PVC foam, the entire hull being strengthened with web frames
and molded FRP stiffeners. It is the intention of Symbol to build this model
in a modular assembly system in order to shorten construction time, reduce
secondary bonding and laminates and ultimately reduce the total weight of the
vessel.
Finally, without totally eliminating all the amenities that boaters expect to find on yachts in the twenty first century, we have endeavored to limit the number of options of materials and interior arrangements to simplify and shorten building hours, thereby passing the reduced cost of building back to the consumer. This doesnˇ¦t mean buyers wonˇ¦t have options available to them but only in a more controlled manner than Symbol Yachts offers in their larger models.
