I. Goals & Objectives

A. Vessel Name

C. Vessel Use Patterns

(i.e. hours per year anticipated, distances traveled, purpose)

Operational (hours/year)

Normal Long Distance Run (miles/km)

Other Service:

II. Principal Vessel Condition

All calculations will be based on this data, so this should reflect the principal operating condition of the vessel.

A. Vessel Make/Model

Other hull type:

Composite material:

D. Dimensions (supply units)

1a. Length, Overall

1b. Length, at waterline

2. Beam

3. Draft

4. Deadrise angle at stern

5. Number of propulsion units

(single, twin, triple, quad)

6a. Weight, operational (full fuel)

6b. Weight, normal max load

describe fuel volume:

describe cargo weight:

describe passenger quantity:

7. Transom thickness

(surface the stern drive is mounted to)

III. Engine Room Geometry

A. Distance from transom to engine room bulkhead

FWD - rear engine room

AFT - midship engine position only

B. Engine Position in Hull

1. Front of engine

2. Front engine mount centerline

3. Bell housing adapter face

(where transmission attaches)

C. Transom Rake Angle

D. Distance from engine centerline to vessel centerline

(keel – for tie bar length in twin applications)

E. Engine from trim pumps to helm control station

(usually transom mounted)

IV. Proposed Engine/Gear

B. Engine Make/Model

C. Rated Horsepower (maximum)

D. Rated RPM (maximum)

E. Rated max fuel consumption

(gallons or litres per hour at max output)

F1. Transmission Model

F2. Transmission Ratio

Please describe if helms are needed, and their location

V. Prior Performance

Note: Information about prior trial performance of the vessel (or one exactly like it) will improve the accuracy and reliability of the analysis. Define this data as accurately as possible - do not guess. This data should be for typical operation at the vessel condition described above.

A. Location of Trial

1. Trial speed (kts)

2. Were current wind speed and headings accounted for (averaged)?

B. Previous Engine and Propulsion System Characteristics

1. Engine make/model

2. Rated max power

3. Rated max RPM

4. Engine RPM (max attainable) at trial speed

5. Propulsion system make/model

6. Transmission and/or drive ratio

7. Number of propulsion units

C. Propeller Characteristics

Make

Model

1. Diameter

2. Number of blades

3. Pitch

4. Cup type, if any
