Gas Heating / Electric Cooling 3 to 27.5 Nominal Tons 48TC WEATHERMAKER® rooftop units were designed by customers for customers. With a gauge plug, centralized control center, plug & play accessory board, “no-strip screw” collars, and handled access panels, we’ve made the unit easy to install, easy to maintain, and easy to use. Units are pre-wired and pre-charged with environmentally sound Puron® (R-410A) refrigerant at the factory. The units are factory tested in both heating and cooling modes.

By eliminating boat roll, Seakeeper transforms everyone's experience on the water. Your guests go from sick to smiling, and memories turn from "never again" to "best trip ever."

Don't Leave Port Without It The opportunity to change a fundamental human experience does not come along every day. We set out to create gyro stabilization technology so effective that it would forever transform boating. By reducing boat roll, we knew we could make time spent on the water much safer and vastly more enjoyable. Since the introduction of the first Seakeeper, we've seen and heard thousands of times how Seakeeper has changed people's lives: the astonishment, excitement, relief, and joy they exude when the gyro turns on and the boat settles, is magical. Seakeeper is a computer controlled gyroscope that eliminates most boat roll, including the fatigue, anxiety and seasickness that goes with it. Typically, the Seakeeper weighs between 2% - 4% of boat weight, requires half or less the power of air conditioning, and fits in available space in the back half of the boat. Our models can accomodate boats 30' and above. Approximately 25% of the units we ship are installed aftermarket and can be installed virtually anywhere on board.

Low Maintenance & unobtrusive Installation Unlike traditional fin stabilizers, the Seakeeper gyro is installed safely inside the hull where it can’t be damaged by the hazards at sea; with no added drag, no effect on your top speed, and minimal maintenance. What is a Seakeeper and what does it do? It is a computer controlled gyroscope that eliminates most boat roll, including the fatigue, anxiety and seasickness that goes with it.  Because of this game changing effect, the world's top boat builders are now installing Seakeeper, and since 2008 we have shipped over 3,000 units. How much does the Seakeeper weigh, and what are power and space requirements? Typically, the Seakeeper weighs between 2 and 4% of boat weight, requires half or less the power of air conditioning, and fits in available space down in the after part of the hull.  Nothing extends outside the hull and the Seakeeper is a small percentage of the overall volume of the boat. Is there a Seakeeper suitable for my boat and what will it cost to buy one?

Seakeepers are suitable for most boats 30 feet and above. If you are buying a new boat, and the Seakeeper is not already standard, consult the builder’s option list for pricing. These option prices will typically include the cost of handling and installation.  manually reset ac unitIf Seakeeper is not offered on the new boat you are buying, or, if you already own a boat, the MSRP is as follows:small marine ac unit Up to 10 tons, vessels 30-40': Seakeeper 3DC -  $30,800creative ways to hide your ac unit Up to 20 tons, vessels 30-50': Seakeeper 5 -  $30,800 Up to 35 tons, vessels 50-65': Seakeeper 9 -  $68,900 Up to 70 tons, vessels 65-80' : Seakeeper 16- $91,900 Up to 100 tons, vessels 80-100': Seakeeper 26 - $152,475

The time and price of a retrofit installation will vary, with easier (and smaller) retrofit installations as little as $5,000 and larger and more complex to $35,000 or more.  Typical retrofit installation timeline is 1-3 weeks. If you are buying a new boat, please consult directly with the builder. If you already own a boat and are interested in a retrofit, please contact Seakeeper direct or consult with one of our Global Partners.How much does a cubic yard of asphalt weigh?
