Pelican has long been known for its airtight and waterproof cases which are used globally by professionals that need to keep their gear safe and dry. The Pelican i1015 case ($35) brings that level of protection to your iPhone, iPod touch and several other smartphones. The i1015 case provides a watertight seal which protects your device from water and sand. The case has a pass through port for the headphone jack and space for storing cables. It's the perfect iPhone case for the boat and the beach.
The iHome iHM77 speakers ($38) are my new favorite portable speakers for the iPhone when size and weight is important. I replaced a much bulkier boombox style iPod speaker system which these tiny speakers because they're easy to toss into my beach bag and produce surprisingly big sound for compacts. The iHM77s collapse down, accordion-style, when not in use and the bottoms attach to each other via a magnet. They're rechargeable via the included USB cable and the mini eighth-inch plug will connect to almost any device. You'll get lots of bang for your buck with these tasty little treats.
If you're a waterbug AyeTides ($10) is a must-have app in your iOS arsenal. It displays tides and currents for over 10,000 locations and is perfect if you boat on a tidal river, surf or fish. Choose a location alphabetically, geographically or near your location, then save it for easy access. Holding the iPhone in portrait mode displays the information in a summary table and rotating it to landscape shows a convenient chart (pictured). The best part is that AyeTides works offline and doesn't require an Internet connection. If you regularly find yourself checking tide tables, this is the app for you. It will keep you from running aground during low tide and tell you when your secret wakeboarding spot has enough water.
