Never mind I found it last night.

I didn't know who made these. It was Marquipt.
It's a combination gang plank and ladder.

Thye have lots of interesting products.

Anyone know anything about these. I'm trying to
design something for my boat for use as a boarding ladder

Better describe what you're after.
Most med moored boats just use a gangplank.
Usually you can tie up close enough to just step aboard.
