Hi All,
I am intersted in possible building a lift for my Cat 25. Has anyone done this or seen a home built lift. I am building a new garage shop and I think it could fit right in front of the main door, not in the building but outside it.

If you have an arc welder and tools for cutting and shaping mild steel (ASTM-A36 hot rolled shapes), I imagine you could fabricate a lifting frame, something like a mini-Travel Lift without the wheels, out of appropriately sized I-beam and channel shapes. The actual lifing mechanism would best be done with two chain hoists, one for the forward end of the boat and one aft. I suggest chain hoists because they are simple, durable, low-maintenance, reliable, and not all that expensive. The current retail price for small quantities of structural steel is about $0.75 per pound, which would make your lift frame cost several hundred dollars at least, plus the cost of the chain hoists and 10,000# capacity cargo straps to make a sling. Would you need this often enough to make it worth the cost, compared with just doing your bottom jobs at a boat yard, using their travel lift? Do you know a civil or structural engineer who could do the design analysis for low cost or gratis? Because of the severe consequences of having this lift frame fail - with you maybe underneath it - you would want an engineer to check the design for adequate shear and moment capacity in the beams, and compression capacity in the columns. Did you see the photos someone posted here a week or two ago, of a davit-type hoist over on the East coast, that collapsed and smashed the Catalina 25 that was being lifted? You don't want to risk having that happen to your own boat!
