Adding a Temporary AC Power Hookup

Hi Maine Sail,

I am working on my prep for wintering in Boston Harbor this year and have a question about adding a temporary AC power hookup.

In talking to other winter liveaboards, many will simply run a second shore power cord into the boat and put an adapter on the end to plug a heater directly into the second shore power cord. This doesn't seem to be a safe. Am I wrong?

I do need to add a second shore power connection but I only need it for one winter. I was on a jobsite the other day when the temporary panel gave me an idea. The boat will be shrink wrapped following a system similar to Tim R's when he was wintering in Portland, ME. Why couldn't I put a temporary panel under the shrink wrap on deck?

I have an extra shore power cord. I could cut the end off it and wire it into a small electrical panel (I have a 4-space, 8-circuit that I got from a jobsite that only has 2 spaces knocked out). I could then wire the 2 breakers that are in the panel to temporary GFCI outlets were I need the additional power (I was thinking of running two heaters on the additional shore power cord). The panel is an outdoor panel used on construction sites. But it would also be under the shrink wrap.

This approach would also eliminate the twist lock connection. I am upgrading the permanent shore power to the Smart Plug. But this setup would prevent me from having to buy 2 smart plug setups.

This seems too easy. What am I missing?

Be afraid...very afraid...

...of the heaters they have wiped out more boats than can be counted(the unattended ones that is) it may be ok to do that if when you leave the boat you turn off the power at the source its never a good practice to leave a boat plugged up with the power on with a temporary power.....to much can go wrong when no one is looking
