OOC:
I'll go ahead and level set with you all. The plan was to have the boat have to navigate through sharp rocks to get close to the beach and let you guys off, which would be handled by a skill challenge. If you guys want to circumvent it, I should probably be ok with it, as players are supposed to be empowered. Just keep these things in mind:
If the boat is left behind, you will have to get back to it somehow.
If you go by air there is an extremely high chance of being spotted as there is a guardian that would notice you.
The water is deep enough for the boat, but sharp rocks can damage the hull. A small boat can navigate failure easily, but is still not safe.
Essentially, I see you have these options:
1. Take to the skies but risk getting attacked mid air over the water.
2. Take a small boat, which would be stealthy but easier for the rocks to break.
3. Take the ship and crew, but you will need to help it get through safely.
