conditional tags in sidebar

I am trying to put a conditional tag in my side bar. So when a user is on our “cruise line” page there is a sublist of ships. Above this list it says the word “ships” only if on a specific template that will be applied to the cruise line pages..

<ul>

<?php
if (is_page_template('cruise-line.php')) {
        // on a cruise line page then spit out extra title
         $children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0&depth=1');
echo $children;

}
else {
$children = wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0&depth=1');
echo $children;
}
 ?>
</ul>

Is the code I’m trying to use and modify. The top one I want it to add a title ‘ships’ above the list.
