Re: iPad Charging - 12V vs. Inverter

Here's a good write up on USB chargers. I bought a couple of the Scosche units - they're very low profile.

Re: Good source for marine grade crimp connectors?

If Genuinedealz sells what I need, I buy from them. For the odds and ends that they don't carry, I can usually find the small quantities I need in eBay.

Re: Continuous duty, non-thermally compensated alternator: options?

Re: installing a new gas tank for my 28' boat

My quarter berth inboard wall is made of a couple plywood panels, which are screwed in place, and can be easily removed. I had them out a few months ago to replace my wet exhaust.
