CMM Marina Planning & Development 2 — Questions and Answers
Question 1: What is the purpose of a travel lift or marine railway at a marina?
- To transport fuel between storage tanks
- To haul vessels out of the water for inspection, maintenance, or dry storage (Correct answer)
- To move vehicles in the marina parking lot
- To launch jet skis only
Correct answer: To haul vessels out of the water for inspection, maintenance, or dry storage
A travel lift or marine railway hauls vessels out of the water for bottom painting, repairs, inspections, or winter dry storage.
Question 2: Which of the following best describes a 'head-in' slip configuration at a marina?
- Vessels are stored with their bow pointing toward the dock
- Vessels are moored in a continuous row along a single face dock
- Vessels are stored on land with the hull facing up
- Vessels are stored perpendicular to the dock with the bow toward the finger pier end (Correct answer)
Correct answer: Vessels are stored perpendicular to the dock with the bow toward the finger pier end
Head-in slips place vessels perpendicular to the main dock with the bow toward the finger pier end, maximizing density and ease of boarding.
Question 3: ADA guidelines for accessible marina floating docks specify that gangways over 80 feet in length must have a slope no greater than what ratio?
- 1:5
- 1:10
- 1:20 (Correct answer)
- 1:12
Correct answer: 1:20
ADA guidelines specify that gangways over 80 feet long serving accessible floating piers must have a slope no steeper than 1:20 at any tidal state.
Question 4: What does 'linear footage' refer to in marina slip inventory management?
- The total perimeter of the marina property
- The total length of dock space available for vessel berthing along dock edges (Correct answer)
- The length of the fuel dock fuel hoses
- The distance from the marina to the nearest navigational aid
Correct answer: The total length of dock space available for vessel berthing along dock edges
Linear footage refers to the total length of dock face or slip space available for vessel berthing, used to calculate capacity and revenue potential.
Question 5: Which factor most commonly drives the need for dredging at a marina?
- Excessive algae growth on dock pilings
- Sediment accumulation that reduces water depth below safe vessel draft requirements (Correct answer)
- High tidal fluctuation exceeding 10 feet
- A surplus of vessel moorings
Correct answer: Sediment accumulation that reduces water depth below safe vessel draft requirements
Sediment accumulates over time and reduces navigable depth, requiring periodic dredging to maintain safe access and vessel draft clearance.
Question 6: What is the primary advantage of floating dock systems over fixed piers in tidal areas?
- Lower initial construction cost
- They rise and fall with the tide, maintaining a constant freeboard height between vessel and dock (Correct answer)
- They require no maintenance
- They are unaffected by ice damage
Correct answer: They rise and fall with the tide, maintaining a constant freeboard height between vessel and dock
Floating docks maintain a consistent deck-to-waterline relationship regardless of tidal fluctuation, improving safety and ease of boarding.
