Rudder blade protection
The skeg can take the first contact before the blade or stock takes the full load.
Underbody protection / offshore design
Built for Protected Steering
Why Antares uses skegged rudders for offshore passagemaking.
The direct answer
Skegged rudders protect one of the most exposed parts of the boat.
The skeg sits ahead of the rudder blade, helping take the first hit and support the stock. It does not make the rudder indestructible. It gives the steering system more protection, better load support, and a more practical service story offshore.
We struck a log and felt the helplessness of no steering and the closeness of a lee shore.

Structural stock support
A skeg-supported rudder gives the stock support along the assembly instead of leaving it as a freestanding spade.
Beachable service, by design
Skegged rudders give the underbody a structure that can support practical dry-out or beachable service in remote cruising grounds.
Evaluation checklist
Three questions to ask about underbody protection.
Use these at haulout or during a pre-purchase inspection.
- What takes the first hit: the rudder blade, or a skeg ahead of it?
- How is the rudder stock supported, and where do impact loads go?
- If there is damage, how practical is the repair where you plan to cruise?
Buyer questions
Clear answers before you compare boats.
Use these questions to frame a more useful conversation about the Antares 44, Antares 46, and the way you plan to cruise.
What is a skegged rudder?
A rudder arrangement that uses a fixed skeg as a protective and supporting structure near the rudder blade. The skeg helps intercept direct impact and provides additional support for the rudder stock, changing how loads distribute through the assembly compared to a freestanding spade arrangement.
Why does rudder protection matter on a cruising catamaran?
Steering loss offshore can become urgent, and rapid repair is rarely available far from a yard. Protection against grounding, debris, and impact loads is most valuable precisely when you are furthest from help.
Does a skeg prevent rudder damage?
No. It improves protection and load distribution, but contact hard enough to damage a spade rudder can still cause damage to a skegged arrangement. The value is meaningful improvement in tolerance and inspection confidence, not an absolute guarantee.
Next step
Look closely at what is protecting the steering when the water gets shallow, dirty, or uncertain.
This is one of those details that feels abstract at the dock and very real offshore. Review how Antares protects the rudder, supports the stock, and keeps repairs more manageable when cruising far from home.
