Night Fishing Pictures - tips?

[wheresmy50]

I just bought a Pentax Optio W30 since my last camera went for a little swim last fall.

I know it's a fairly popular camera amongst fishermen, so I was wondering if anyone has any tips about the best settings for fishing pictures?

Since autofocus if difficult in the dark I was thinking of manually setting the focus for 5', and enabling the flash. I'm just not sure which mode to start with, or if anyone else hads a better way that has proven itself.

Also, Anyone find a good small case that you can open with one hand?

Thanks
