Info. wanted on wrecks to snorkel in Door County

[AandA]

I'm not planning on doing any scuba this time during my Door County trip as my buddy--my husband--isn't coming this time. It's "women's week" in Door County and I happen to be the only scuba certified one so that's why I'm inquiring about snorkeling (which my husband prefers to refer to as "free diving" as he's quite good at it. The slippery rocks don't sound too enticing knowing the women I'm offering to introduce snorkeling to. Any alternatives for easy entry without slippery rocks assuming the surf is down (I do understand the great lakes as I've shore dove Superior a few times.).
