I like that we can upload our own documents, this helps save time when filling out paperwork at port or in office! It is helpful if you have multiple boats working together as it allows all of them access from one system instead having each person log onto his/her separate pc's which would be more difficult due to distance between pcs & internet speed issues - but overall very useful tool!! The hardest part about using Prisma has been finding someone who knows how to use Excel (which they don't do) so much easier than learning another program such us Access etc..
