HOW TO DIMENSION A SAILING CATAMARAN? This article is to help start a catamaran design process. At the end of the day, the performance of a sailing catamaran is dependent on three main dimensions: length, sail area and weight. More waterline length means a faster boat, more sail area means a faster boat and less weight means a faster boat.
On successful completion of the unit, students will be able to: explain properties and use of different boat types. collect and compare technical data of boats. define relative speed and select the boat type. explain boat properties due to dimensions and parameters.
29 Ιουν 2010 · There are two major dimensions of a boat hull: The length of the hull L H and length of waterline L WL . The following consist of arbitrary values to illustrate a calculated example. L H = 12.20 L WL = 12.00
Length, Draft and Beam. Length, draft, beam and mass are in fully loaded condition at this stage of dimensioning. There can be found two major lengths in a boat: length of hull L. H and length of waterline LWL. Let's put in some values to get a calculated example.
Boat’s characteristics affecting her performance are measured. The International Measurement System (IMS) is a set of rules that defines what and how is measured on the boat. By using IMS, the complete boat can be measured, including the hull shape, appendages, propeller, stability, rig and sails.
To estimate the wet weight, you can use the following formula: wet weight = dry weight + weight of the motor + (fuel tank capacity x 7) + (water tank capacity x 8) + (weight of boat with full tanks x 15%). ... Hull weight vs dry weight. When buying a boat, it is important to consider its weight. Boat weight is comprised of two main measurements ...
Each of the above measurements and ratios provide information about the basic geometry of the hull itself and how the hull relates to the driving power provided. All of it is to be considered essential, and should always be readily available on the drawings or from the designer.
