Noise & Vibration
Flemings are known for their whisper quiet, smooth ride. To begin with, the engine room air intakes
are located under the cockpit coaming, away from the main cabin and pilothouse. This location not
only helps to reduce noise, but it eliminates corrosive salt spray from entering the engine room.
We use the Aquadrive system as standard on the Fleming 55, 65, and 78, and the 58 comes standard
with the Seatorque Bolt on Shaft System (BOSS). This is a totally enclosed, oil filled, self-contained,
shaft and thrust bearing assembly.
These systems transfer the thrust from the propeller directly to the hull, not the engine. Thrust
bearing brackets are bolted to full-length steel bars encapsulated in the vessel's massive engine
stringers, so the propeller's thrust is transmitted to the hull. This allows the engine to be
mounted on soft engine-mounts. The engine is virtually "floating," thereby reducing its vibration
from being transmitted throughout the vessel.
The generators are double-mounted on anti-vibration mounts, which are bolted to highly dense
platforms. This approach also results in a "floating" engine, which contributes to whisper
quiet, vibration free operation.
Additionally, great attention has been given to soundproofing the engine room and insulating it
from the rest of the vessel. Lead-based sound insulation and foam are utilized throughout the
engine room, and an attractive soundboard material is used on flat surfaces, including fuel
tanks. A specially fabricated, fiberglass composite cabin sole is now used on all Flemings
and features honeycomb construction for additional stiffness and insulation. All engine room
hatches utilize rubber gaskets and are clamped down tight.
As a result of all this focus on reducing noise and vibration, Flemings are known the world
over for their whisper quiet, ultra-smooth operation.
