Thanks for your inquiry. Probably the best boat for your needs is the Expedition. It can voyage easily in open ocean conditions and can carry a lot of camping gear. The Oxford Wherry is a fun light boat, but it needs to be in more sheltered waters (can only voyage in waters similar to what a canoe can contend with). Pushing hard, you can maintain about 5.5 mph in the Expedition and a more relaxed all-day rate is about 4.5 mph.
Let me know if you have any other questions.
