The document discusses the design and physics of a boat created by a team of students for an assignment. It includes sections written by different students on the boat design, physics calculations, keel forces, and sail forces. The team designed a multihull boat with movable sails and blocks for keels. They calculated that the boat force is 7,408.8 N, gravity force is 11,136.12 N for the 1,136.12 kg boat, and with 10.6 mph winds the sail force would be 24.6 N.

2. Why? and Results
✤ We were given this assignment to create a boat, find
the mass, and some forces that would make the travel
at a speed and to also be balanced when it would be
sailing. !
✤ After many weeks of planning and calculating the
forces, as a team, we looked up the formulas on how
to solve the problems. We were able to balance the
boat for when it sails.

3. Boat Design
“When creating this boat I had the
idea that with all the different types of
hulls we could choose from a
multihull would be the best for use to
make since it is the most stable. I then
looked into what types of keels a
multihull would have and I found out
that they are just these little blocks on
the bottom. did create ones like those
pictured there, but they did not save
so we had wyatt finish it up. I then
looked into sails and made a design
like this because this sail can move
with the wind, as well as it can against
it. I put all of this together in hopes
that it would look the best that I could
make it.” - Tryston Lewis
