Every ladder needs a minimum of 8 cm deck surface to fit the Deck Sockets.
Other than that, it can be installed on almost any kind of position on a vessel, with the appropriate accessories, and you must choose the type of fittings you need for your installation.
The basic fittings are comprised in the price of the ladder, with additional cost for more complex fitting systems.
If you need to install the ladder in further positions, you can buy additional kits at their full price, checking the "additional fitting position kits" further down below.
