Step-ladders, are hulls that are divided into levels that are scaled by the steps and seen on the sides of their respective hatches. These levels, trap air under the hull by reducing the surfaces that come in direct contact with water, thus reducing friction without lowering the support surface, as is the case with conventional hulls attempting to achieve this reduction by lifting the bow very high their.
Staircats acquire so-called ventilation channels, which are the hollow place we see in their step and which is designed to introduce more air by further stimulating their operation.
WHEN THE STEP WORKS
The step works as soon as the boat crawls and as the speed increases, the more powerful it becomes.
STEPS WORK ON TIME?
As the wave height and speed of the boat allow it to be in constant contact with the surface of the sea the steps work.
STEPS GASTERS REDUCE IN THE WEATHER?
The steps at all do not affect the operation of the hull on the waves. Its performance there is defined by the shape of the bow from the corner of V from its supporting surfaces and from the other shipbuilding elements. When the wave height becomes so long that the boat stays half-planted, the steps cease to work and the hull simply behaves like a simple monorail.
HOW DOES THE STEPS HELP ON A BOAT ON THE GENERAL TOURIST USE OF OPEN SEA?
In principle, steps increase performance vertically. Increasing performance means a vertical reduction in consumption. This is because the more efficient the hull is, the less power it needs. So when we want to travel with 27-30 knots, for example, we need to open the throttle much less than in a lower performance hull, so obviously we have a big economy. Step-ladders can at medium speeds at least have increased stability since the support they use is very important from a monorail since they can have their bow lower without raising the friction due to the air that introduces under the steps.
A STEPS GAME IS NECESSARY SPORTS OR RACING?
Definitely no . We will see widespread American horses using one and two steps taking advantage of their advantages at medium speeds.
WHAT COMES WITH THE STEPS IN THE FLOOR?
In recent years we have seen some boat manufacturers of various sizes use one or two steps on the bow with different shapes and directions. The steps on the bow are the same as those on the hull. So when the tread is especially long the bow "cuts" the ripples the steps there reduce the resistances, thus reducing the braking observed in all the hulls. When the use is tourist they improve the comfort of the passengers. When it's racing, performance.
WHAT IS THE TRUTH FOR THE DEEP V GASTRONS IN HIS BEHAVIOR IN THE CURRENT WEATHER?
Many times we will hear about boats that go surprisingly with 8 and 9 beaufort. Myth. In principle we should not be talking about beaufort but about wave height. Why the air has different effects depending on the area. And elsewhere the 6 beauforts are 1 metro wave and elsewhere 3. So all the planing hulls whether they are with or without steps can have their full performance up to about 1 metric wave. From then on, they require handling, speed reduction, etc. so they can work. Horses with deep V have a much better behavior (softer ride) under these conditions and as long as they can be stuck. Be careful though. The hull works with the bow and up to its middle portions. It is wrong, therefore, to evaluate and measure the hulls in the mirror and say "It has 25th in the mirror, so it is deep V, so it goes well". The hull faces the weather as we said with the bow and the middle parts of it. From here and after, the big corner is useless. And it negatively affects both stability, economy and performance.
WHY ARE THEREFORE THAT THE FOOTS DO NOT HAVE INSUFFICIENTLY LEVELS IN THEIR PRESENCE?
Why there is a maximum acceptable V-shift from the bow to the stern. So if we start from a very big bow on the bow, we can not end up with a null corner on the stern. This is what we will see as the longer the lengths of the boats the greater the margins there is to reduce the corner of the V at the stern. The right achievement of this balance greatly defines the performance of the hull in the difficult times.
WHY CAN WE NOT HAVE A FRIDAY MAGNIFIED VESSEL TO GO TO LARGE INTERNAL AREAS, BUT YOU SHOULD TRAVEL MALADE AND DRY IN DIFFICULTY WEATHER?
Because a second basic principle is the width of the hull. A bulky bow can not open a road in a high waves because it has to drain too much water and its large surfaces will lead to a fatal blow. But also in the ejection of large quantities of water that the air will grab and carry on the deck. And would you reasonably ask that "nice to the bow, to the stern, why not have a great width?" Exactly for the same reason as with the depth of V. There must be a harmonious combination of bow and stern width so that it can there is a good flow of water. So when we start from a narrow bow fatally we will end up in a narrow stern. Here many shipbuilding tricks are often made, such as the solution of the "double chine effect" we use on our hulls, trying to increase somewhat the width of the stern.
