I don't have local knowledge of your area. However, there are some good arguments for taking the direct route. First, the difference in distance isn't much, but, the longer you are on the water the less you can trust the weather forecast. Also, if you do have something go wrong with the boat it is often better to be further off shore. You may also want to decide based on what the forecast is for that day. If the wind is ripping off the beach, you could get closer, so the waves don't have much fetch. If the wind is going onto the beach, you don't want to be on a lee shore, and the waves could get higher as they get into shallow water. Just my $.02.
