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
• Ultimately 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

7
SELECT TYPE OF SAILBOAT PROJECT

• Required features
• Project design decisions

8
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

11
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 to buy and cost more to
  maintain

12
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 lt Cutter lt ketch
• Cost
• Sloop lt Cutter lt Ketch

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

15
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 grounding

PROPULSION

• Most sailboats have diesel engines
• Yanmar, Volvo, Perkins, Westerbeke, Vetus
• HP
• Appropriate for the boat size
• Drive method
• Shaft more expensive to install cheaper to
  maintain
• Sail drive cheaper to install more expensive to
  maintain
• Fuel tank size
• Bigger diesel engines costs more and uses up more
  fuel
