StormN post pretty much said it all. One thing to consider about electrics is definitely power.
My best bud has a crab/shrimp pot building business and some of his most recent designs are a bit to effective...imagine 33 dungies in one pot...the guys honda puller barely got it off the bottom. Electric unless it was huge wouldn't have.

BTW breakfast on Hood Canal is fresh out of the cooker steamin hot crab...yummy. Makes my float float upright.
