Apple’s iPhone is a great tool for anyone, but it has some features and available applications that make it particularly great for Stand Up Paddle Surfing. The phone I’m going to cover is the 3G version, which is handiest since it has built-in GPS capabilities. In fact the iPhone GPS is especially useful since it has special features that increase the accuracy, even when GPS satellites are obscured by weather conditions or terrain.
Unfortunately the iPhone is not waterproof, so you need a dry carrier of some sort. There are some fairly expensive and clumsy hard case versions, but the touch screen of the iPhone makes hard cases problematic. Thin clear drybags enable you to operate the phone right through the bag, and both talk and listen through the bag or via headphones. My current favorite is the OverBoard case, which has a compact closure system and a built-in headset jack. The only drawback is that the back of the case is opaque so you can’t use the phone’s camera without taking it out of the case.

I sent them an email about it, but they responded (more or less correctly) that the iPhone camera is so lame that they think most people are more interested in an armband and flotation, which are hard to provide along with a camera window. What they are not considering is geocoding photos, which I find extremely useful. Even a fairly crappy picture becomes interesting when you automatically know EXACTLY where it was taken.

As it is the iPhone is great for downwinders and distance paddling. It has a clock, a stopwatch to time your run, it’s a superb iPod player for your music, and if you or someone else gets into trouble or needs a li [...]
