When we bought Sonny IV, which does not have a swim platform, one of my first safety oriented questions was - "How the h*ll will I ever get back aboard if I fall in?" While she has a transom door it is normally securely latched shut. And that transom is like a giant wall if you're looking at it from the water!

For the first season I jury-rigged a plastic rope emergency ladder like this:
Not optimal, and it didn't look very good, but it gave me peace of mind.
I later added a dive ladder that can swing up and lock in an upright position. Great ladder, but kinda ugly sticking up back there, and it gets in the way of opening the transom door, especially if you dock stern to.
Besides not being the most attractive - the two options above also share a potentially fatal flaw of - if you don't rig them ahead of time they won't be there when you need them.
I was wandering a boat show a number of years ago and spotted an odd looking thing on the back of a new sailboat. This little round fitting labeled "Emergency Ladder". I remember thinking "What a great idea! ALWAYS there when you need it!" Naturally - I forget to get the brand off of it. But, I turned my google powers loose and figured it out. It was a Recessed Emergency Ladder from Osculati in Italy.
So, let's order one! But no. While I found it on Amazon it was not available. I put it in my shopping cart anyway, and that entry sat there for a couple of years. I'd check on it now and then, but it remained unavailable.
Then, a couple of weeks ago I got one of those "An item in your cart" messages from Amazon. Sure enough there was my mythical ladder! It's sitting in it's little box here next to me and I hope to install it this weekend! Woohoo! So excited for safety!!

I'll post an update once it's installed - but I wanted to take this opportunity to remind my fellow AOGers - "Be careful out there!"
Have a great summer!!
