New Wizard Design Features; New
Motor Selection Wizard; Miscellaneous Weight Wizard; Angle Increment
Calculator; Quick Design Wizard; WAngle
Calc Wizard; Deadrise Wizard; Power Calc Wizard; Velocity
Calc
Wizard; Propeller Wizard; Quick Lift Wizard, and an Expanded
Wizard Tutorial
Deadrise Wizard - If
you don't know the deadrise angle of your sponsons, use the Deadrise
Wizard to determine the angle of the deadrise of your
sponsons or center pod running surface. Just input the
height measured at the outside edge and inside edge, and the
width of the running surface (pad) - the Calculator will
determine the angle and automatically transfer to the input
field.
Quick Design Wizard
makes it easy to obtain a generalized design by
selecting one of the 'standard' performance tunnel hull
and power catamaran design styles. The dimensional and
setup design arrangements for your selected hull type
will be automatically applied to all the design input
fields. |

Use the New
2008 Motor Design Wizard
to easily
input the dimensional information for your setup.
Just select your OEM engine manufacturer and highlight
your model from the over 575 listed.
The published manufacturers specifications are all there
- correct MaxHP, Height, Weight, RPM and gear ratio will
be automatically input to TBDP. Includes NEW 2008 motor
UPDATES! Includes specs for
Mercury, Merc Hi-Performance, OMC, BRP, Evinrude, Johnson,
Yamaha, Suzuki, Nissan, Honda, Tohatsu, Mariner,
MerCruiser, Volvo-Penta, Steyr.

Approximate propeller
sizing can be obtained based on your motor
specifications. Engine RPM is predicted by TBDP7
based on your design, setup parameters and operating
performance; your predicted propeller pitch is
calculated and displayed with recommendations. |

Design Performance
Comparisons are NOW easy, with the Dual
Graphic Performance presentation.
Automatically compare the performance trends of your
'new' design trial modifications to your 'base' design,
with the Graphic Comparison mode. Is the new
design 'better'? Is it faster? Is stability
improved? It's easy to see now! Makes
it EXTRA EASY to see exactly how the design changes
affect performance in all areas. |

Quick Lift Calculator calculates
Lift, Drag & Force coefficients for Tunnel hull,
ModVP Pad and Vee-hull configurations. Use this
great feature for quickly optimizing pad or vee deadrise
configurations, by analyzing Lift, Drag, L/D coeficients
and HP utilization for a given velocity and
design. OUR USERS ASKED FOR VEE-HULL calculations
- AND NOW THEY'VE GOT THEM - even consider true vee hull
or vee-pad configurations for all calculations! |

Lift and Drag
distribution can be easily reviewed and analyzed
by using the 'pie-chart' view. The percentage (%) of
each Lift (or Drag) component of the total Lift (or
Drag) is shown. Check the legend to identify the
respective components.
Aerofoil shape
and configuration alternatives are available, based on
extensive research using NACA shape characteristics,
thickness, aspect ratio, height above surface, with
tunnel hull configurations and loadings.

Tips of the day
show design and performance improvement tips. Automatic
BlowOver check – too much angle of attack
(Wangle) can create a condition of greater lift than
weight, causing blowover.
A new feature will check for this condition, if
you desire, and correct the WAngle during a Velocity
Optimization performance check.
Automatic
WAngle increase – when doing a Velocity
Optimization performance check, a new feature will test,
if you desire, for all angles of attack (Wangle)
for maximum velocity condition.
Imperial
or Metric Units feature
- with automatic conversion of all input & output
data with click of button.
TBDP can now conform to both Imperial (ft-lb-mph) units
and Metric (m-kg-kph) units. A simple "click"
on the menu <Change
Design Units> and the input units on all screens
will automatically change from Imperial to metric –
or from metric to Imperial. If design data has been
entered, it will be automatically converted to the
units chosen. All performance analysis (output) data,
graphs, recommendations and charts will also be
automatically changed to the corresponding units.
[see
sample screen for control]
Results Wizard presents
an analysis summary for each optimization scenario, highlighting
specific design/performance recommendations to review for
improvements.
Now includes color printing
of 34 performance graphs!
Your tunnel hull design analysis now
considers performance and stability effects of Center Pod,
multiple sponson steps, selectable aerofoil shapes,
cockpit configurations - even single or multiple drive
train configurations - and lot's more!

Dozens
of new features and design options
Get actual dimensions of the
aerofoil selected using the Aerofoil Dimensions View
feature. The lengthwise (chord) location and upper/lower
dimensions of the aerofoil are shown for your design,
automatically calculated for your chord length, wing thickness
and aerofoil type selection. You can use these dimensions
to analyze or draw an actual template of your wing design.
Simulate performance with steps
using the Step Selection design frame. Standardized design
integration of your steps are created when you select "No
Step" or "One Step" or "Two
Steps". You can even locate the step on the running
surface, and specify the depth of the step.
Accurate top speed prediction, new
acceleration models, angle increment calculator, velocity range
calculator, acceleration modeling with elapsed time prediction,
motor height calc's.** 34 Color graphic performance

Print the easy-to-use data
input form, to simplify data and dimension
collection. All required dimensional inputs are listed in
an organized sequence, with an easy location to write in your
boat’s information. It is then easy to transfer this
information to your TBDP7 data input screens.
