What makes this a Whaler question is that's what I want lifted. I have 2 Whalers 99 OR 18 and 87 15 SS I want to get lifts for the pier, but know nothing other than the ad claims.

Any mfg better than another or any lifts to avoid? I would like to get one 10,000lb lift in case I get a bigger boat in the future, I wonder if I can get a smaller size and upgrade the lift motor

Boat lifts, out here in the west, are very common. They seem to work well IF they are setup correctly in the first place (properly installed and adjusted for the center of gravity of your particular boat). The only problems I have seen with them is their hinge points tend to squeek when the water is rough (loud, irritating noise) and if the tank connections leak air they lower the stern of your boat into the water (could flood over the transom). thats a rare occurance but it does happen. The most common unit seen around here is by a company called Hydro-Hoist. If you find that your interested, I can get their phone no. for you. I have also seen some very nice looking units in Florida, can't recall the brand name but, I have also seen them advertised in various boating magazines (Try Southern Boating). They are a great way to go, however, in cold country, your boat is above the water not in it so freezing weather is more of a concern as water is usually warmer than air temp.

nice article, but my boats and cars strung together wouldn't total 90 feet.

Monnas Rock, when you say--"if the tank connections leak air they lower the stern of your boat into the water (could flood over the transom" Are lifts pneumatic?

I assumed they would be mechanical motors riding up a shaft

Most of the lifts I've seen consist of two or three cylindrical air tanks hooked together with a boat cradel mounted atop. There is an air compressor mounted on the dock with one way air lines leading to the tanks. When you turn it on, the tanks inflate to a predetermined boyancy. To lower the boat into the water you simply let the air out of the tanks with a control valve. Very simple, Very efficiant. As you bleed air from the tanks, the stern (heaviest end) goes down first, then the bow. The lift capacity is determined by the number and size of the tanks. For instance a 10,000 lb. hoist might have a 20'x 3' tank in the middle with 2 12'x2.5' tanks outboard. Brackets are mounted to the dock fingers on each side. They have hinged pivots that allow the whole unit to go up or down. Sounds complicated when I try to explain it but it"s really very simple.

Down here everyone runs alum lifts. They all use the same Ace electric engines. What determines the weight is the beam and cable size. A 10k lift is the way to go. Once you step up to 13k they get expensive. A nice 10k lift installed is about $4500. The 15' you can get a piling mount lift for that. For an idea get an Overtons catalog.

Most boat lifts I have seen do not support the Whaler hull on it's keel, as should be done.

So be sure you get one set up properly for keel support.

I was never happy with the cable lifts, so I built my own hydraulic lift that works like a floating boat trailer. 3 Stolz rollers, two carpeted bunks, one boat trailer winch stand. Similar to the hydro-hoist concept, one end of my lift sinks, like backing the end of the trailer in the water. From there, it's either winch on, or roll off... Rollers are in the same spot as they are on the trailer, so it's no worse than being on the trailer for my 15' Sport.

Pix available.
