3rd Achievement- See previous posts for Sketch Ideas

4th Achievement- See previous post for Model

5th Achievement

          Approach- A v-bottom design

  +It will obtain one of the achievements

  Change: Make the bow pointed to help it go smoother through the water

  ? Will it even stay up or will it roll over right away?

  ! Some kind of wings for balance

6th Achievement

        Surface Area: 60 yards x 1.88 inches x 3 rolls

        180 ft x 0.15667 ft x 3 rolls

        28 ft squared x 3 rolls

        84 ft squared

7th Achievement

        I believe we should get this achievement because we did complete all of the criteria. Unfortunately we did not get a picture before we put our boat in the water, and it's understandable if that makes our team invalid for it.

8th Achievement

       V-Bottom: We were very proud of our v-bottom, and that we were the only team in our period to do so!

9th Achievement

       Balance Master: Under about a foot of water Josh was able to stand in the bottom of our boat for five seconds.

10th Achievement

        Feedback

1. Change- More layers of duct tape on the stern
2. + It didn't roll over like I expected it to
3. ! I think the wings helped a little
4. ? Would it had made a difference if we built a keel
5. Change- Make the wings longer
6. ? If the rope didn't break would it have helped us at all
7. ! It wasn't a complete failure
8. ? Was it worth taking the risk of it not staying upright
9. Change- Make a more sturdy base
10. + The extra strip of cardboard on the v-bottom helped it keep it's shape

11th Achievement

       How Low Did You Go?

           Surprisingly we remained above water for a few minutes. The water that came into the boat came in through the back at the bottom because there was a small hole. Even after it was completely under water it was only a little more than a foot deep. The Surface Area displaced enough water to keep Josh afloat.

12th Achievement

      Stick Through It: As a team we faced some challenges on equal work for everybody. I also was absent for a full period and a half which caused us to get behind in work. Even with these problems we stuck together as a team and had a really great time in the pool with our finished boat.
