Catamaran Design, Stability & Systems (Q1–25)
1. The primary source of stability on a cruising catamaran is:
A. Deep ballasted keel
B. Buoyancy in two widely separated hulls
C. Crew weight alone
D. Daggerboards only
Catamarans rely on form stability from wide beam and twin hulls.
2. Compared to a monohull, a catamaran typically has:
A. More heeling and deeper draft
B. Less heeling and shallower draft
C. More heeling and deeper draft
D. Less initial stability
Wide beam gives high initial stability; hulls are shallow.
3. Which component connects the two hulls and provides structural integrity?
A. Forestay
B. Cross beams (and bridgedeck structure)
C. Backstay
D. Rudder tie rod
Cross beams tie hulls together and support the deck/mast loads.
,4. On many cruising catamarans, the downward force of the mast is primarily
supported by the:
A. Forward crossbeam only
B. Center crossbeam integrated into the bridgedeck
C. Stern beam only
D. Daggerboard trunks
The central structure carries mast compression.
5. A “seagull striker” on a catamaran is located on the forward crossbeam and
primarily serves to:
A. Store anchor gear
B. Reinforce the area against forestay tension and wave impact
C. Act as a swim platform
D. House the engine
It strengthens the forward beam where the forestay loads and waves hit.
6. A forward projection of the bridgedeck designed to soften the impact of seas is
called a:
A. Sponson
B. Nacelle
C. Keel
D. Transom
The nacelle helps deflect waves and reduce slamming.
7. On catamarans with daggerboards, these boards primarily provide:
A. Ballast
B. Lateral resistance and improved windward performance
C. Steering control
D. Engine cooling
Daggerboards reduce leeway and improve upwind ability.
,8. When sailing to windward on a daggerboard catamaran, the daggerboards should
generally be:
A. Fully raised
B. Lowered
C. Removed entirely
D. Locked at mid-height only
Lowered boards increase lateral resistance and reduce leeway.
9. When sailing downwind on a daggerboard catamaran, daggerboards are often:
A. Fully lowered
B. Partially or fully raised to reduce drag
C. Removed
D. Locked in place permanently
Raising boards downwind reduces wetted surface and drag.
10. Catamaran rudders are typically:
A. Larger and deeper than monohull rudders
B. Smaller but more efficient due to lack of heeling
C. Nonexistent
D. Only on one hull
Less heeling allows smaller, efficient rudders; often linked by a tie rod.
11. Which of the following systems are typically duplicated on a catamaran?
A. Only the stove
B. Engines, fuel, electrical, cooling, and bilge pumps (one set per hull)
C. Only the anchor
D. Only the heads
Twin hulls mean duplicated engine and system components.
, 12. An engine’s starting battery on a catamaran is generally:
A. Shared between both engines
B. Collocated with that engine and charged by its alternator
C. Located in the salon only
D. Not required
Each engine usually has its own start battery and alternator.
13. To maintain balance and avoid excessive list, it is important to:
A. Load all weight in one hull
B. Distribute weight evenly across the boat, especially fuel and water
C. Keep all gear on deck
D. Store heavy items only in the bow
Even weight distribution preserves trim and performance.
14. A typical cruising catamaran sail plan consists of a large:
A. Unbattened mainsail and spinnaker only
B. Fully-battened mainsail and a roller-furling jib
C. Gaff rig only
D. Single sail only
Fully battened mains help support a large roach; jib is often furled.
15. The mast on many cruising catamarans is supported by a forestay and shrouds
forming a:
A. Single stay rig
B. Tripod arrangement (forestay plus shrouds, often no backstay)
C. Ketch rig
D. Cat rig
Many cats use a tripod mast support without a traditional backstay.
16. Compared to a monohull, a catamaran’s turning radius under power is generally:
