Underhulls - The Background

The most popular series of motor yachts ever
produced from 1980 to the present was designed
by the Bayliner Marine Corporation.  As many as
10,000 of these 32', 38', 45' and 47' motor yachts
still cruise the waters today and have an excellent
reputation for great value in a larger boat.  

The Problem

With the availability of better technology, boaters
today are adding more electronics and other gear
to their vessels.  The downside is that when fully
loaded, these excellent motor yachts have
somewhat sluggish performance and handling
capability.  Their semi-displacement hull was
designed for economical cruising at lower
speeds while a more planning type hull is better
for speeds over 10 knots.
The Solution

An aftermarket hull adaptation to actually changes the
shape of the hull to a more conventional style.  
Underhulls is an innovative fiberglass mold that
transforms the older, soft chine semi-planning hull of
their 32' and 38' Bayliners to the more true planning
hull design.  This hull retrofit provides the lift to plane
quicker, provide a more stable ride, better handling in
all seas and enhance the visibility at the helm.  
Performance, while improved, does vary with each
individual boat.
How it Works

Underhulls function much like a massive trim tab, utilizing the length
and width of the hull to create a more natural and efficient curve
downward.  This provides the pressure to create the needed lift to
plane the boat.  Use of trim tabs to maintain a planning hull speed is
reduced and engine horsepower is restored to its primary function of
increasing forward hull speed.  The common sense application of
Underhulls changes the semi-displacement version into a true
planning hull design currently in today's production techniques.  After
the application of Underhulls to a boat, the use of trim tabs become
substantially more effective.  As always, in following sea conditions,
they should be in the up position.
