Departure Planning does not take your comfort settings into account. It compares four different departure times and summarises the conditions along the route for each, helping you choose a safe and suitable start window. For each departure time, it always calculates the fastest route.
Weather Routing, on the other hand, can be set to either find the fastest route or factor in your comfort settings. This is why you are seeing a difference between the Departure Planning summary and your route.
The Weather Routing will produce the following error message if a route cannot be found due to comfort settings, the route will then be fastest time.
As you have comfort settings on the router could not find a route under the following default parameters, toggle ON Advanced to see these parameters.
The router outputs three data points at each route point: Roll, Vertical Acceleration, and Slamming Incidence.
Roll is the root-mean-square (RMS) roll amplitude in degrees. When roll motions are large, moving around the boat and performing tasks becomes difficult. Objects not strapped down are likely to move. A roll RMS limit of 4 degrees is often used to move around the boat and complete tasks safely. Roll tends to be the largest in beam seas. For sailing yachts, which have a heel angle, the roll is the change in heel angle due to the waves.
Please note: this is not 4 degrees roll to Port to upright then 4 degrees to Starboard, think of the RMS of 4 as just a baseline number.
Vertical Acceleration is pitching or a vessel's up and down motion. This is characterized by the rising and falling of the bow and stern. Vertical acceleration is the root-mean-square vertical acceleration in 'g's' (1.0 = Earth's gravity 9.81 m/s^2). Vertical acceleration is a good indicator of the potential for the crew to get seasick. The algorithm considers the primary, secondary and tertiary swells to calculate the overall vertical acceleration for the boat. The higher the acceleration, the more likely the crew will get seasick.
A vertical acceleration limit of 0.2g is often used for safely performing tasks and avoiding seasickness.
Slamming Incidence is the likelihood of experiencing at least one slamming event per minute. For monohulls, slamming is measured near the bow (10% LWL from the forward extent of the waterline). When this part of the boat emerges clear of the water and then impacts the water with a high relative vertical velocity, it is called a slamming event. For sailing catamarans, slamming is measured at the cross-deck structure (bridge deck), and again is based on relative vertical velocity. For either monohulls or catamarans, a slamming incidence of 50% is considered excessive and may lead to hull damage or injuries to the crew.
