Hi Ken. Yes I had a marince construction company for roughly 5 years until they changed the Workman Comp laws around here for this type of business. I have my 280DA sitting on a 10,000lb lift. Most (maybe all) 10k lifts use the same materials as a 13k lift except the 13k lift is usually wider to accomaodate a bigger boat. The last 4 years in business I installed Pr0-Lifts. There are built to last and the people there were great to deal with. You can check them out at http://www.floridaboatlifts.com/index.html. If you call ask for the owner, Tom Kramer and tell him Perry with Skyway MArine Construction sent you. He can also tell you if they have an installation dealer in your area.
