what shapes are used to prevent boats from tipping over in storms?


in very rough weather, what are the best boat shapes/designs to prevent the boat from tipping, this is asking for a boat 32-42' x 16' wide, and 18' tall designed to drive 20-80mph with 20-40 being the normal speed.

the thought of huge waves tipping the boat just scares the shit outta me

A combination of shape, strength and careful positioning of the draft and centre of gravity is what stops a boat from becoming bowled over by the waves - and if done really well, even getting it back upright again if it does become overwhelmed. (See film).

Boat shape certainly compliments this combination and different shapes have different characteristics.

Probably the most seaworthy designs in the world are the cutters of the US Coastguard.

At the mouth of the Columbia River on the US West Coast, nature has contrived to produce one of the roughest bodies of water in the world.

The Coast Guard has found over many years of experience and design that the best type of boat shape for use in these waters is the double-ended V-bottom type, with deep forefoot and high, flared bow, which has subsequently evolved there.

It is a combination, from bow to stern, of all the types of hull-shape, with a great deal of fine tuning, to produce a type of vessel that puts extreme seaworthiness at somewhere near a pinnacle.

The advantage of the pointed (also rounded) stern is to reduce the tendency of broaching in a quartering sea. This means to be swung around and out of control by the force of the following wave:-

"If the forefoot is too deep and there is no skeg, it may be impossible to steer such a boat. When a boat of that profile runs down a wave, she buries her nose in water and her stern lifts high and clear … [lifting the rudders and propellers clear, and thus making them useless] … Around she goes, pivoting on her deepest point, the bow. Next step in this tragedy is violent rolling in the trough of the seas. Capsizing or swamping is the last act.

If a deep forefoot is desired, then the profile must be balanced at the stern with a deep skeg and rudder. … Every line must be a compromise" ¹

[Typed in from the book, below. Not copied and pasted.]

So good was this design that the resulting vessel was also used by the RNLI (Royal National Lifeboat Institution - the UK national coastal rescue service) with a number of boats being purchased from the US Coastguard.

The boats were signified as the 'Waveney' Class of lifeboats here in the UK, with the numbers beginning: 44 001 / 2 / 3 etc.

Here is some super film, and pics, of some of these vessels (together with their earlier and later incarnations) on station, possibly at Morro Bay, or the aforementioned mouth of the Columbia river, USA:

Lifeboat Cutters:

Is this good enough performance to set your mind (and your bowels!) at rest? ;-) )

The 'Waveney' features quite a bit here, (spot the 44 on the bow) but the best view is at 2. 05 minutes into the video (towards the end) cruising along in flat calm water with shore in the background). Also in calm, 17 seconds in, on the right.

In really rough conditions, seaworthiness is very much a function of the person at the helm, ultimately.
