Hull
form development and performance analysis for
power and sail boats is yet another dimension to VGYD's extensive
repertoire of marine engineering services. We offer state-of-the-art
research and development programs for the optimization of either new
designs or existing boats.
VG30 - To aid in the design process
of the
VG30, VGYD undertook an unprecedented research and development program
comprised model development, tank testing and a post analysis and
optimization. A complete parametric analysis was made to develop the
lines for 2/3 scale model, which was then tested at IMD. Approximately
150 runs were made in the towing tank at various speeds, heel angles,
yaw angles and rudder angles. This information was used to create a
matrix of data in order to calibrate the VPP. The VPP now became a
powerful analytical tool in allowing VGYD to quantify hull variations
in terms of performance, by racing the variants against the base boat.
It also made it possible to fine tune the hull form resulting in what
was considered to be the best performing design. This high-tech yet
cost effective approach taken by VGYD has yielded a wealth of knowledge
and insight into the performance characteristics of the VG30. It not
only served to validate the design, it also translated into winning
boat for the owner (see article "Cost effective R&D).
F&S
Boatworks - of
Delaware have used VGYD
to assist in developing the lines for their 57, 61 and 70 foot custom
sports fishing boats. These powerful and extremely efficient hull
forms, with an innovative longitudinally stepped dead rise, have been
very successful and are quite popular with armature and professional
sportfisherman alike.
Atlantic
Boat Company -
The Duffy & Duffy
"Down East" Maine lobster boat is probably one of the most classic
styles of lobster boat there is. The Atlantic Boat Company, the
builders of these vessels, have used the services of VGYD for the
passed six years for the design of interior and exterior layouts of
their extensive line of both work and pleasure boats, hydrostatic
studies, and powering analysis. VGYD is presently working on the hull
geometry for a 33 footer based on the traditional lobster boat style.
Burke
Design - VGYD
was brought in to
undertake the repowering of a Trojan 40 Express Cruiser. With the aid
of sophisticated powering analysis software, the optimal propeller
diameter and pitch ratio were selected to match the horsepower and RPM
of the new engines. This process ultimExpress ately saved the owner
time and money and insured that the boat would not be over powered with
the propellers cavitating at high running speeds.
Jutson
Mount Gay 30 - In preparing his boat
for the Bermuda 1-2, the owner of this Scott Jutson designed Mount Gay
30 contacted VGYD to help him optimize the sailing configuration for
the best PHRF rating possible. This optimization involved a detailed
look at the rating parameters such as sail area, displacement, water
ballast and rig configuration.
Thompson
37
- After the 2007 refit of Rumours and its subsequent successful sailing
season, the owner is looking to optimize the sail wardrobe for the 2008
season. The boat will be competing in PHRF, IRC and OOR events,
therefore the owner looked to VGYD to produce a relatively accurate set
of polars for the boat.
