A plot of drag against speed for each of the models is shown on Figures 12 and 13.
When towed from the bow, the monohull models often became unstable at high speeds and would yaw from one side of the channel to the other. The monohull models were generally stable when towed from the stern. The trimaran model was stable in both directions.
It was also noted that the monohull models developed more dynamic lift when towed from the stern and showed less tendency to "bury." A photograph of model No. 2 during testing is shown on Figure 14.
No attempt was made to correct for Reynolds Number effects since such refinement is unwarranted for this application.
