What is a good comfort ratio?

What is a good comfort ratio?

You can use the following guidelines to interpret comfort ratio results: numbers below 20 indicate a lightweight racing boat; 20 to 30 indicates a coastal cruiser; 30 to 40 indicates a moderate bluewater cruising boat; 50 to 60 indicates a heavy bluewater boat; and over 60 indicates an extremely heavy bluewater boat.

What does comfort ratio mean?

The Comfort Ratio is as a measure of motion comfort. The intention is to provide a means to compare the motion comfort of vessels of similar type and size, not to compare that of a Lightning class sloop with that of a husky 50 foot ketch. The CR is : Displacement in pounds/ (. 65 x (. 7 LWL + .

How is capsize ratio calculated?

Capsize Screening Formula = Beam / ((Displacement/64.2)1/3) The displacement in this formula is measured in pounds. This formula does not take into consideration the location of the ballast or the shape of the hull.

What is a sail number?

Offshore Sail Numbers These sail numbers are an important way of uniquely identifying a yacht for search and rescue purposes, and are a requirement of the Racing Rules of Sailing, Rule 77 – Identification on Sails. The RYA recommend that all yachts have a unique sail number.

What is displacement on a sailboat?

A boat’s displacement is defined as the weight of the volume of water displaced by it when afloat. Similarly, sail area doesn’t tell you much about a boat’s likely performance unless compared to its displacement, which is why we have the Sail Area/Displacement Ratio.

What do sailboat calculations mean?

For a sailboat, the SA/D provides the same metric. The horsepower comes from the wind on the sails and is proportional to the sail area; a boat’s weight is its displacement (in pounds, kilograms, or tons). The traditional calculation for SA/D compares sail area in square feet to displacement in cubic feet.

Can a Catalina 22 capsize?

It is possible to sink a C 22 under the right conditions. There was a full capsize on lake Michigan a few years ago and it was brought about by sailing with too much sail in heavy wind and wave conditions. The boat dipped the sail into the water and the waves started to sink her.

What is a good capsize screening number?

The answer you get is known as the boat’s Capsize Screening Number. If that number is two or less, the boat passes this important safety test. In general, anything over 2 is a failing score and indicates the boat’s stability is questionable.

How do I find my sail number?

You can simply apply for a number online for a small fee – currently about 30 pounds. But this is only the registration. You have to get the actual numbers yourself from a sail-maker or chandlery (they’re very cheap). Registrating a sail number costs you anywhere between $50 – $200.

What do the numbers on sailboat sails mean?

The numbers themselves usually don’t mean anything. Usually, the number is essentially “how many sails of this model have been produced before this one”. So, the first boat will have sail number 1, the 1000th will have sail 1000. Not all boats will come with numbered sails.

Is displacement how much a boat weighs?

If you lower a boat into the water, some of the water moves out of the way to adjust for the boat. If you could weigh that displaced water, you would find it equals the weight of the boat. That weight is the boat’s displacement.
