ASA 114 – Cruising Catamaran Practice
Exam Questions And Correct Answers
(Verified Answers
1. What is the primary reason a cruising catamaran does not
| | | | | | | | |
|heel significantly under sail?
| | |
It has a wide beam and twin hulls
| | | | | | |
The wide stance of the two hulls provides stability,
| | | | | | | |
| minimizing heeling compared to a monohull.| | | | |
2. When docking a catamaran, what is the most effective
| | | | | | | |
|way to maneuver in tight quarters?
| | | | |
Use differential thrust from twin engines
| | | | |
Each engine is mounted on a different hull, allowing for tight
| | | | | | | | | |
|turns by applying forward on one and reverse on the other.
| | | | | | | | | |
3. How does the center of effort on a catamaran typically
| | | | | | | | |
|compare to a monohull? | | |
It is higher due to the large sail plan
| | | | | | | |
, Catamarans often have a taller rig and larger sail area, | | | | | | | | |
increasing the center of effort.
| | | | |
4. What is the effect of high windage on a catamaran when
| | | | | | | | | |
|maneuvering under power? | |
It increases drift and reduces control in crosswinds
| | | | | | |
The large above-water surface area catches more wind,
| | | | | | |
|especially when docking. | |
5. What is the main advantage of a catamaran when
| | | | | | | |
|anchoring?
It is more stable and doesn't roll much
| | | | | | |
The wide beam keeps the vessel steady even in choppy
| | | | | | | | |
|anchorages.
6. Which of the following statements about catamaran drafts is
| | | | | | | |
|correct?
Catamarans generally have a shallower draft than | | | | | |
|monohulls
Their twin hulls are typically narrow and shallow, allowing
| | | | | | | |
| access to shallow waters. | | |
7. When anchoring a catamaran, how does scope differ from
| | | | | | | |
|anchoring a monohull? | |
Scope is typically the same
| | | |
The scope ratio (typically 7:1) is based on depth and still
| | | | | | | | | |
|applies to catamarans. | |
8. What is a bridled anchor rode used for on a catamaran?
| | | | | | | | | |
To distribute the load between both bows
| | | | | |
A bridle reduces swing and strain on one cleat by
| | | | | | | | |
|spreading load across both hulls. | | | |
, 9. Why is it essential to know the height of the boom on a
| | | | | | | | | | | |
|catamaran?
Because it is often lower and poses a head injury risk
| | | | | | | | | |
|Catamaran booms can be lower due to lack of deep | | | | | | | | |
|cockpit, increasing risk of contact. | | | |
10. When gybing a cruising catamaran, what precaution | | | | | |
should be taken?
| | |
Control the boom to prevent slamming due to wide beam
| | | | | | | | |
A wider beam increases momentum of the boom, making
| | | | | | | | |
controlled gybing critical.
| | |
11. What is the typical motion of a catamaran in ocean
| | | | | | | | |
swells compared to a monohull?
| | | | |
Hobby-horsing and slapping due to flat underside | | | | | |
Catamarans may pound on the bridge deck and pitch in
| | | | | | | | | |
certain sea states.
| | |
12. Why do catamarans tend to tack slower than | | | | | | |
monohulls?
|
They lack a deep keel for momentum and turning
| | | | | | | |
The shallow draft and wide beam result in less turning
| | | | | | | | | |
|inertia.
13. If a catamaran begins to fly a hull, what should be
| | | | | | | | | |
|done immediately?
|
Ease the mainsheet or depower the sail
| | | | | |
Flying a hull is a precursor to capsize—depower to regain
| | | | | | | | |
| stability.
14. What sailing technique can help complete a tack on a
| | | | | | | | |
catamaran?
|
Backwinding the jib briefly | | |
