There are race boat shells for different weights of a crew that will be onboard. It is not possible to build a boat of the one-size-fits-all kind. When the design of the boat shell commences, it is designed for a specific weight of the crew. Therefore, it is essential for the racing club to specify the exact weight that will be hoisted on top of the boat before it has been customized to fit. The water line is taken into consideration when designing the vessel, therefore, the exact weight of the crew is measured. After the weight of the crew has been measured, the makers allow the boat to carry and the extra load of 20 to 30 pounds. Sometimes when the importance of the team is lesser than or over the capacity of the vessel, three things can happen. These changes can cause the boat to either sink or not perform to its optimum. Outlining these tips are also handy for those who are considering building a shell for their crew.
The first thing that is affected if the team members are not measured for the boat is the waterline. Every time the weight on the boat changes by 15 pounds, the line increases or decreases by 1/4 inches. Some people believe that if you put a big crew a boat much smaller than its capacity will help create a wetted surface. A wetted surface creates more drag and consequently is better than having a big hull. The belief is incorrect and not correct. The size of the hole that the crew will punch in the water will be identical and does not affect the wetted surface. Therefore, the change is almost negligible when you think that the wet line will impact the speed and performance of the crew on the boat.
Many crews believe that the seat height will determine the surface break than the weight of the crew. They neglect the weight of the crew and focus on the fact that the seats are above the waterline, making it ideal for the team to row. The most effective way to use this theory is to lower or increase the rigging so that the team is comfortable. The team will not be able to find a firm position over the surface of the water with their paddles if they are not in the right position to get some traction. However, this scenario is only present when the crew is lighter. If the team is heavy, then their body weight will be able to alter the traction needed to break the water surface.
Exposed Hull Measurement
It is only natural for the boat with the lighter crew to have their hull pointing up in the air a lot more than a more massive team. The light crew will be able to have a lot of protection when the water is rough, but in windy conditions, their speed is significantly affected. The massive team will sink slightly and will not be affected at all by the hull or adverse weather conditions. Their ability to survive in dangerous waters is tremendous.
