About how much do the ones with the platform cost? My catamaran has one and I really like it for ease of climbing into the boat. Mine's got a kicker bracket one one side and a ladder on the other. I've even seen one with an ice chest mount on one side. I think its made by stainless marine but its aluminum.

I have a Stainless marine on my V20 New like hew one shown for $900+ and the full swim board $2100

I have a Armstrong just like the one shown in the pic now of my Sea Ox.

If the one on ebay goes for $500 that will be a great deal for a new one!!

I got mine as a take off from a local mariner, the guy swapped from a single motor to a twin set up, I got it at the time for $400

The transoms on the V20 is 15* but 12 will be fine!! Mine was a 12 also on the V20, thats what you have power tilt for.
