Like a work of fine engineering, a spring maneuver requires a design. The key is to plan the maneuver by considering the wind, current, and other obstacles, then design the placement and directions of the forces and moments.
There are some other cool things you can do when you consider the propeller thrust over a Catamaran’s rudders.
The long-line-ashore is a useful Mediterranean mooring method. It is mostly used in the Mediterranean as a customary way of mooring a lot of boats along a shoreline.
Wind pushing you away from the dock – This is the simplest scenario. Once you are confident of your plan, release and stow dock lines, then allow the wind to push the boat clear of other obstacles.
Another factor when Mediterranean Mooring with an anchor is that the wind direction determines who is in control…
The wash-lift effect has been documented heavily by Dave Geer who is one of the worlds leading propeller engineers.
The rudder can be a big help because it can change the direction of the thrust force.
While training and earning a sailing certification while on a vacation is possible, it doesn’t make nearly as much sense as you may think if you focus on 2 key questions.
It is important that the person deploying the anchor and the helmsperson are in agreement about the anchoring plan first. Discuss the placement, the direction, the depth, the desired scope, and the setting plan.
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
