Rick,

          I will probably always have some sort of surface support, but the idea is to be able to launch from a boat ramp and to be fairly self supportive. I want to have a good range with the batteries but I'm thinking eventually I would like to have some sort of diesel assist engine that I could detach after long surface trips. Maybe have a big bumper cushion thing and cinch up tight and lock it into place and it would basically be a generator to power the electric propulsion motor. Attaching two floating objects in the ocean would be extremely challenging to say the least but I'm sure there's a way to do it. My sub is sort of shaped like a torpedo so I'm hoping to travel economically.

Brian

Brian - is your sub a vertical or horizontal boat? :-)

Meaning are you going to go down with surface support and plunk around on the bottom or tour along coastlines and make crossings?

Dan,

         I will have a very different situation than you. I plan to operate out by our Channel Islands, Catalina, Anacapa, and Santa Cruz Islands. Catalina is probably the most protected but it can get dicey without much notice as well. There will always be some sort of surge action, running up on the beach would not be an option. Catalina has some nice harbors though, especially on the windward side of the island one of the "Two Harbors" which is the only natural harbor between San Diego and San Francisco. I plan to have lots of freeboard, but we'll just have to see how much freeboard and stability I will end up with! Right now it's kind of a blind date !   I can pick my days though, sometime it's so dead calm out here it's unbelievible, usally in the mornings but in the fall it can stay like that all day.

I sure wouldn't want some anchor banging around thats for sure, keep anchor on support boat.

Cheers

Brian

Brian,

When I don't want the sub to float away from shore, I run up as far as I can and blow the ballast. Persistence sits on the bottom like a rock. I don't have tides to contend with where I am.

If you wanted to anchor in a harbor somewhere, you would probably be better off to have your anchoring equipment carried on your support boat and tied to the sub only when needed. You just don't need things like anchors hanging from a sub. You'll hardly ever use it and it's one more thing to get entangled with.

Hi All,

             Does anybody know the dynamics involved with anchoring a sub. Like would a hook for a typical sailboat be sufficient? It seems to me a sub would stay put better than a sailboat since a sub would not have any wind force on it. But on the other hand the mass of the sub might tend to just hank the anchor away. Unless the anchor was very secure, in which case the sub could just go under water if there was a large swell. Anyone have any experiance with this?   Thanks,

Brian
