sounds like you're going to be ready long before august. if money is tight it only takes one rod to catch a fish
then get your lifejacket and wetsuit/dry gear. I'm imagining Maine is even colder than Mass, in which case you really should consider skipping the wetsuit and going to dry gear. If you already have chest waders all you need is a belt and a dry top and your'e good to go. this article pretty well spells out what's needed. http://www.newenglandkayakfishing.com/c ... thing.html
a few practice trips are definitely in order, but i think you'll be surprised at how quickly you feel comfortable on your yak, after that it's just a matter of picking out a calm day to get out on the ocean.
