Aaron -
You did not say what you are going to use to tow the boat . Something to consider is whether you will net to upgrade your vehicle to comfortably tow a "glass" boat.

Also for your freshwater use what sort of launches do you normally use? Might dictate the size/wieght of your rig.

As always getting a boat is full of compromises.

I fish regularly with a buddy that has a 17 foot arima - a great boat that handles water well and would fit the bill for your salt water fishing. I have a 16 foot Alaskan Lund that I really like - works fine for the Sound/Willapa bay as well as the San Juans and Straits on good days. But not the boat for bigger water - for example bouy 10. But it works great for putting in on lakes - If I can get the tires into 6 inches of water and I can easily launch and load by myself. Have no problems putting it on the beach; don't need a dock, etc.

With the Arima a full sized truck is needed as a tow rig while I get by with a smaller vehicle (a ranger). My lund's 4 cycle is half the size of the one on the Arima. I also put a salt water model 80 # thrust bow mounted electric on the lund which is great for holding position for jigging, sliding along rips while throwing bugs for coho,etc while it freshwater it works well for bass and perch fishing and is the really sweet for the kokanee fishing I do (the remote auto-pilot is really handy).

As I said buying a boat is all about compromises. The ideal boat is really 3 boats. Suggest you make a list of what you would like, your must haves, etc and try to balance that with your budget (should be some deals with the current economy). If you are looking new at times there are some good package deals at the winter outdoor/boat shows. The more homework you do the more likely you will be happy with your choice.

Good luck
