Help with Yugo SSM

[Palindromeria]

Ok ,
i cannot get this mini sub to engage anything. its also quite loud.
noticed in scenrio edit mode that it has no sensors, not even a visual sensor while surfaced. ok , i can understand that theirs no electronics to speak of but someone on board has to have eyes ??

so how do i use DW edit to add a look out ?
do i have to create a new yugo ? can i just alter the existing info ?
will it end up being a specific yugo hull # thats affected ? etc ..
i know enough about the prog to be able to bounce araound and look at stuff but am unclear how to actually get into editing. a tad leery of just jumping in headfirst. there a faq somewhere maybe ?

thanks in advance for any clues
