Ask the operator to assess your catamaran against an actual pen, its fairway and the route to it—not a general length limit.
Catamaran beam and clear berth width
Send length overall, maximum beam, draft, air draft and any tender or projection. A pen that works by length can still be unusable because of finger spacing, piles or neighbouring boats.
Ask whether the quoted width is clear usable space and what fender allowance the operator expects. Photos can help explain unusual davits or boarding arrangements, but written dimensions remain essential.
- What is the clear width of the proposed pen?
- How much side clearance is required?
- Do my tender or davits change the fit?
Multihull fairways, entrances and turning room
A wide berth is not enough if the fairway, lock or entrance is narrower. Ask about turning room, crosswind exposure and whether staff normally assist multihulls on arrival.
Compare the route from berth to cruising water as well as the road trip to the marina. A suitable multihull base should work for ordinary departures, not only a carefully timed first arrival.
- What is the narrowest point on the route?
- Is tug or staff assistance ever required?
- Are there beam-based fees or operating limits?
QUESTIONS ANSWERED
Frequently asked questions about marina berth planning
Can a catamaran use two standard pens?
Only if the operator offers and approves that arrangement. Ask about the exact allocation, price, services and neighbouring clearance.
Is advertised marina beam the same as berth width?
Not necessarily. Confirm the clear usable width and every restriction between open water and the actual pen.
Why does fairway width matter?
It affects whether the boat can turn and align safely, especially with windage. The operator must assess the proposed route.
