Hi, Welcome aboard,
For your first post you probably don't want to be looking for locations just as a word to the wise. I will tell you though. In RI there are a few things you need to consider before heading out.
#1 Safety First- RI is extremely jagged and the fishing is tough from shore but can be highly rewarding and addicting. Make sure you buy Korkers and waders. The water is warm enough now that you wont catch a cold from it but if you take a digger on the rocks you want to have protection.
#2 Saltwater fish eat and hunt the similar to fresh water fish it is just a much larger stage. They seek shelter current structure etc. They will be around all of those things.
#3 Pick a place in RI on the coast and fish it. Don't get frustrated if you don't catch fish we all go through it. Right now things are slowing down. They will pick up again around the second week in September. When you catch a fish remember what time of day it was what the tide wind and moon were. Chances are if that situation repeats itself in the near future the fish will be there again.
Best of Luck Welcome aboard don't be afraid to use the search feature some of these threads have more info than some of the Books out there.
