The lift is from a company Freedom Lift. We have had a number of different tender solutions over the years (weaver, lifting davits and a winch/tow cable) and really looked at a lot of solutions out their (and talked with owners of them) and the Freedom Lift was a hands down winner.
Beyond design and function the main selling points for me was that they were a marine design team that know the correct materials and loads that must be part of the design (many others just seemed to be playing with design concepts without real world marine expertise) and secondly that they stood behind their product and provided real owners we could talk with about long term experience. Additionally we got good feedback from a few of the yards we spoke with for the installation. I would not recommend this as a DIY project unless you have marine architectural experience (there is a lot of load on the transom).
They only make a single product but they customize the build based on your boat/tender (mostly based on transom angle/height and weight of tender). Our model was the 4485 HD Gen 3. They are really helpful and took the time to work with me and the yard (CSR) to plan out the installation. I had it shipped to the yard and they then did some reinforcement of the transom and angled tabs for mounting.
Pretty awesome to pull up in the tender, get out stably on the swim step and push a remote to lift the tender into place, secure and be underway.
The lift is not cheap, about $25K (we negotiated some discounts to about $20K) and the install was easily another $10-15K (some of the work was part of the stern thruster and swim platform fiberglass work)
Anyway, more info than you probably wanted but if you choose this approach hit me up for some other lessons and tricks we learned through the process. Here is one of the owners contact info for Freedom Lift:
