SUMMARY

The discussion focuses on designing a small boat with a self-draining deck, emphasizing the need to determine the waterline and deck height. Key principles include buoyancy and Archimedes' principle, which states that the weight of the boat must equal the buoyancy force to calculate the waterline. Participants recommend using these principles to solve for the water height based on the boat's weight and load. This approach ensures that rainwater can flow out above the waterline effectively.

PREREQUISITES
  • Understanding of buoyancy and Archimedes' principle
  • Basic knowledge of boat design principles
  • Familiarity with weight distribution and load calculations
  • Experience with marine engineering concepts
NEXT STEPS
  • Research buoyancy calculations in marine design
  • Learn about the impact of load on waterline height
  • Explore self-draining deck designs and their advantages
  • Study the principles of stability in boat design
USEFUL FOR

Boat designers, marine engineers, hobbyists interested in small craft design, and anyone involved in optimizing self-draining deck systems.

hi peoples... i have to design a small boat with a self draining deck. the boat has to be able to allow rain water to flow straight out above the water line. how do i work out where the waterline will be before i build the boat? and how do i calculate how high the deck should be? (depending on the weight of the load??)

any help will be greatly appreciated

Lookup buoyancy and the Archimedes' principle.

Basically, you can set the weight of the boat equal to the buoyancy force and you can solve for how high the water will reach on the boat.
 
thank you matt... very helpful...i will do just that...
