Respondents that said "yes" to receiving educational materials and the control

group both had a similar mean knowledge score of 8.06 (SD = 2.5). Only one individual

knowledge item was significantly different between those that answered yes to receiving

education and the control group: more "yes" respondents knew that feeding a manatee

will disturb it (X2= 6.6, p = 0.011, Table 18).

 There was no significant difference in the mean attitude score between those in the

treatment group that said they received materials and the control group (t = -1.07,

df= 405, p = 0.285), or in any of the individual attitude items (Table 19). Nor was there

a significant difference in any of the behavior items between those that said yes to

receiving educational materials and the control group (Table 20).

 A quarter of the boaters additionally were asked if they could finish the slogan "Go

Slow! Manatees below!" The interviewer read the first part of the slogan" Go Slow," and

respondents were asked it they could finish it. Only 4% said "Manatees Below," 44.2%

gave an answer that included the word "manatee," and the remaining 52% gave an

unrelated answer, or could not respond.

 Path Analysis

 We employed a path model to estimate the direct and indirect effects of the

independent variables (knowledge, attitude, and experiences) on a dependent variable-

(behavioral intentions, Figure 2). A regression analysis showed attitude to be a positive

predictor of behavioral intentions (r 2 0.075, B =.055, p = 0.000). Two experiences

showed a negative effect on attitude: the number of times seeing a manatee while boating

(r 2 0.097, B = -2.55, p = 0.03) and years of boating experience (r 2 0.097, B = -.104,

p = 0.02). The number of times seeing a manatee while boating did not significantly

predict behavioral intentions (B = 0.034, p = 0.75) nor did years of boating experience
