Scantling determination and ISO 12215

Scantling determination and ISO 12215

Scantling is the process of determining the dimensions of the different elements of a structure (e.g., panels and reinforcements in the case of a hull) so that they can be manufactured. ISO 12215 is a scantling standard that applies to recreational and commercial craft and workboats up to 24 meters in length. Compliance with ISO 12215 is mandatory for obtaining the CE marking and, therefore, for selling boats in the European Union.

Structural considerations in sailboat design

All boats shall have adequate strength to keep the hull watertight and withstand hydrostatic and hydrodynamic loads without breaking. Besides these water-generated forces, several other loads, like the rig loads, may also affect the hull and deck of a sailing boat.

Frictional resistance of a boat or yacht (calculation)

Calculate the total frictional resistance of a yacht: hull, keel, and rudder. The frictional resistance is a force that is generated when the underwater parts of the boat and the water around are in relative movement. It is a hydrodynamic force, and as a resistance, it works in the opposite direction to the movement, trying to slow the boat down.

Frictional resistance of the hull (calculation)

The frictional resistance is a force that is generated when the underwater parts of the boat and the water around are in relative movement (the boat moves through the water, or, in other words, the water passes down the boat). Therefore, it is a hydrodynamic force, and as a resistance, it works in the opposite direction to the movement, trying to slow the boat down.

Surface waves

Surface waves are created by disturbance forces applied to a specific area. It can be either the wind, a surface vessel moving through the water, an earthquake, landslides, a splash, gravity (as it is the case for tides), or any combination of them. When studying ocean waves, we consider them to be the superimposition of single sinusoidal waves with different frequencies and amplitudes.

Points of sail

The points of sail refer to the course a boat is sailing in relation to the wind. They are defined in reference to the wind angle, which is the angle between the course sailed and the direction of the wind. The following terms are used: close-hauled, close reach, beam reach, broad reach, run, dead-run.

What the hydrodynamic resistance is and why it matters

The motion of a sailing yacht through water requires energy to overcome resistance. It is essential to know the mechanisms behind the generation of this force that works against the movement so that we can make the resistance of a new design match the project's overall performance goals.
