Presentation:

South Dakota relied on 3 people to deliver their presentation.  They used 1 screen and presented their effort from a business standpoint.

After a brief introduction, the team described their hull design.  They elaborated on the changes made from last year and went on to hull analysis.

They explained how the stresses were obtained and they outlined how the forces were modeled.  The team determined that the maximum moment occurred in the 4-person and 2-man races.

 The team explained how they developed their design and elaborated on the constituents selected to meet the requirements.  Then they described mold and canoe construction. 

They explained how they placed 3 layers of concrete with 2 layers of reinforcement in between and said that the process took only 7 hours to complete.  They ended by describing their curing and finishing techniques.  Then invited the judges to ask questions.
