When Rick and Arron enter and search the houseboat they conclude that its got some supplies including a few guns but "no ammo" hence that's why the occupier has gone

This is just my own meanderings but if I was a target ie the boat full of supplies then its likely i'd stash the ammo elsewhere.. I'd also have at least two escape routes. For arguments sake lets say Rick and Arron are approaching from the front and kept occupied by the moat full of the undead then "boots" can slip quietly out the back in another boat onto the shore and watch them from a safe distance (sat next to his stack of ammo!!)

We know that "boots" has seen them on the boat and whether it belongs to whoever "boots" is is still being discussed on other threads.

Again this is random and slightly inspired by another thread on this episode but it would were to anchor the dead to the lake base effectively creating a barrier (that looks random but infact is quite strategic) you've created a mine field like effect that you can get through quickly but intruders like Rick and Arron cannot. Like I say just rambling meanderings

Thoughts appreciated

 

You're right BUT what could look like a random walker in a boat could be parts of "boots" minefield. We already know two boats exist, the one with bullet holes that R and A used and the immaculate one with a walker in it plus life jackets,etc in it.

Damn here's another random thought. The walker boat had no water in it. I'm no nautical expert but a canoe without a cover soon fills with rainwater unless its being looked after and emptied and used regularly. My gut tells me that whether its "boots" or another person as the house boat occupier. They are still near by and very much alive and kicking.

 

I don't disagree on any thing you're saying but I think on last weeks thread Neuro (TWD guru) informed me the tree walker and the house boat were a long way apart (and who am I to argue with a guru).
