PROJECT
A series of connected homework projects
Application of most of the concepts covered in class
Groups
Size 5
PROJECT BACKGROUND
Conduct all the necessary project activities to build a one-off custom designed mid-sized cruising sailboat
Determine
What type of sailboat project to undertake
Identify what components are needed
Identify what resources are needed
Determine the project plan including sequencing
Perform budget and cost estimation
Identify a means of monitoring the project progress
Etc.
Will need to use the Internet to perform project research
HOMEWORK #1PROJECT SELECTION
Select type of sailboat project to undertake
By evaluating on project selection factors
Using one project selection model
SELECT TYPE OF SAILBOAT PROJECT
Required features
Project design decisions
REQUIRED FEATURES
Must be off-shore cruising capable
Can make extended voyages over oceans
Category A
Required systems
Fresh water system
Sanitation system Toilet and shower
Cooking facilities stove
Electrical system lights, instruments etc.
Air conditioning and heating
REQUIRED FEATURES
PROJECT DESIGN DECISIONS
Size
Rig design
Hull material
Hull design
Propulsion
Many other design decisions, but we have to draw the line somewhere
SIZE
Sailboats are measured by overall hull length and width (beam)
The longer the boat, the wider the beam
Every five feet, the effective volume doubles
Forty foot boats are actually twice as large as 35 foot boats
Popular sizes of these types of boats
36, 38, 42, 44
Bigger is more expensive buy to and cost more to maintain
RIG DESIGN
The rig consists of
The masts
The sails
Supporting wire stays
Designs in order of complexity
Sloop 1 mast with one headsail and one mainsail
Cutter 1 mast with two headsails and one mainsail
Ketch 1st mast with one headsail and one mainsail, 2nd mast with mizzen sail
Flexibility under adverse conditions
Sloop < Cutter < ketch
Cost
Sloop < Cutter < Ketch
RIG DESIGN
HULL MATERIAL
Fiberglass
Cheapest material and easiest to make
Blisters, but does not corrode
Easy to repair
Aluminum
Most costly material and most difficult to make
Does not blister, but can corrode
Difficult to repair
Steel
More costly material and more difficult to make
Heavy can only build larger boats
Does not blister, but corrodes
Easy to repair
HULL DESIGN
Fin
Lighter weight
Lesser stability
More maneuverability
Poor protection against grounding
Modified Fin
Full Keel
Heavier weight
Greater stability
Less maneuverability
More protection against ...
