Boats
are created in many different ways. Some are born out of market research,
some are the result of consumer focus groups, and some are just one man's
vision of what he wants to build. The Tempest 60 Hardtop came to be via
none of these routes. Instead, she is the offspring of an owner who wanted
a new, modern yacht but loved his old one too much to give her up and
a designer who knew how to combine the best of the old with the best of
the new. The
old boat in question was a Tempest 60, which the owner purchased in 1990.
A classic open sportcruiser, she displayed the kind of squarish, sculpted,
European-influenced styling that was all the rage in the early `90s,
and she had much to recommend her. Her hull was unusually deep--21
degrees at the transom--which helped make her seaworthy and steady
in deteriorated conditions. She was built with an eye toward strength:
a solid-FRP hull with Kevlar and vinylester resin, a Klegecell-cored deck
and hardtop, balsa-cored stringers ahead of the engine room, plywood-cored
engine beds and 6061 aluminum engine frames, and plywood-cored frames
on three-foot centers. But
what made the Tempest 60 unique was her drive system. The T-Torque Drive
was the creation of Adam Erdberg, president of Tempest and designer of
the 60. Erdberg designed the T-Torque to combine the advantages of surface-piercing
drives with the durability of straight inboards. Like all smart ideas,
this one is simple: Prop shafts on five-foot centers exit the transom
at about an eight-degree down angle. The struts that support them are
cantilevered from the transom, as is the T-Strut abaft them that contains
the rudders, rudder quadrants, and hydraulics. Since nothing moves but
shafts, props, and rudders, the system is strong; since everything exposed
is stainless steel, it is also impervious to corrosion. The moderate prop-shaft
angle improves propeller efficiency, and since the noncleaver propellers
are well aft where there's clean water, they get a better bite.
The engines are well aft, too--nearly up against the transom--so
on-plane performance and running attitude are enhanced. While
the T-Torque was never popular in terms of numbers, those who owned boats
powered by it (including the U.S. Coast Guard) swore by it. That includes
the owner of this Tempest 60, Hull No. 6, whose 10-year-old drives have
never been touched. But
while the hull form, construction, and drive system have all stood the
test of time, the 60's layout was a bit long in the tooth. Indeed,
its open design offered distinct disadvantages to a man now 10 years older.
Besides the fact that he was exposed to the sun and wind, the low, sleek
windshield provided precious little shelter. The original square cockpit
offered a nice blend of amenities, including forward wetbar, port-side
lounge, and starboard sunpad, but it also lacked shade and wasn't
what you'd deem comfortable by today's standards. The deep
transom had a stylish camber, but its thickness wasted a lot of space,
and the bolted-on swim platform had a distinctly added-on look. So as
much as the 60's owner loved his boat, he reluctantly decided it
was time to trade her in for a more modern vessel. |
