What are the Chines on a boat?

A chine in boat design is a sharp change in angle in the cross section of a hull. The chine typically arises from the use of sheet materials (such as sheet metal or marine ply) as the mode of construction.

What does chime mean on a boat?

April 27, 2020. The chine of a boat refers to the change in angle in the cross-section of a vessel’s hull.

What is a chine line?

Where is the chime on a boat?

In terms of boating, the chine is the area of a vessel’s hull where the bilge angles up to become the topsides of the hull. The hull is the watertight section of the vessel, above which is the deck and any other superstructure feature.

What is chine walking on a boat?

The chine walking experience refers to the situation occurring with high performance vee-hulls as the boat accelerates, lift increases and the running surfaces raise out of the water. So, the hull will now start to rock from port chine to starboard chine – back and forth. This is called “chine walk”.

What causes chine walk on a boat?

Chine walk appears to be primarily caused by the relative motion of the boat’s center of gravity and the hydrodynamic lift centroid in the lateral direction. At low speeds, the waterline across the beam (width) of the craft is relatively wide and progressively becomes narrower as the boat’s speed increases.

What is chine walk?

What are strakes on a boat?

On a vessel’s hull, a strake is a longitudinal course of planking or plating which runs from the boat’s stempost (at the bows) to the sternpost or transom (at the rear).

Now, chine runners are simple flanges on the bottom of a flat bottomed boat, like this: which are used as a substitute for a leeboard or daggerboard, etc, to allow a boat to sail to windward. The advantages are obvious – simple with shallow draft.

Why does a bass boat chine walk?

Chinewalk happens when the boat has the ability to run with little wetted surface. The boat is trying to run on a small pad, once it falls off this pad, it falls to one side then bounces over to the other side. Hence chinewalking!

What causes a bass boat to chine walk?

Chine walk is the chain reaction you allowed to happen because you failed to keep the boat upright on the pad. You never trim up far enough, or go fast enough, that the foundational reason for the roll instability of your boat goes away. You still have engine torque and you still have very little hull in the water.

What is a slow boat to China?

What is a reverse Chine?

Reverse chine. Reverse chine – easy to draw but a bit more difficult to describe. The chine is where the bottom of the boat joins the side. Most chines incorporate a spray rail – a horizontal section up to a few inches wide. These deflect spray and increase lift. A reverse chine is where this spray rail is angled down and much wider than normal.
