Why is a Formosa so spacious and stable?

Formosa is renowned for their spacious decks and if you compare to other designs, you’ll notice the space extends right through to the front. There has been a number of design decisions made on a Formosa Hull which combine to give you the amazing space you see when entering the boat. Formosa Marine have refined their hull design to include an ideal balance between the degree of deadrise, reverse chine, generous freeboard, wide beam and ergonomic layout, making you feel like you are in a much larger boat and more importantly, provides a stable platform for you to enjoy. A sharper deadrise may reduce travel time marginally and gives a much more narrow boat too, which isn’t pleasant during a long day in the rough, and with many people on board, space is probably more of a concern. Performance should include the whole day on the water, even at rest. We challenge you to see for yourself and compare to other boats on the market; the deck space will surprise you!

Formosa offers more stability

The innovative Quad4™ Water Ballast with an innovative ‘Off Keel’ counterbalance design that is industry-leading in terms of achieving even greater on water stability. Unlike traditional keel ballasts, the Quad4™ four (4) chamber ballast, combined with a wide beam and reverse chine hull, minimises hull roll from the swell or internal passenger movement. Once you are on your way, the 4 longitudinal stringers empty rapidly, allowing you to get on the plane without any change in performance. This is an option now available on all models and sizes.

Even though every Formosa hull is naturally stable (with the wide beam and reverse chine hull), the Quad4™ Water Ballast offers an additional level of stability that really comes into its own under offshore conditions. Quad4™ Water Ballast is available on all models and sizes (standard on all models and sizes from March 2023).

PRO DECK™ True Self-draining Decks

A true self-draining deck quickly removes excess water from the floor area to the outside of the boat while in heavy seas, when a wave hits or just washing down the deck at home. You can now upgrade your boat to include the Formosa PRO DECK™ Self-draining Floor on all models 495 to 595. All Formosa hulls 635 and up carry PRO DECK™ as standard (standard on 635s from March 2023). Formosa’s PRO DECK™ is a true self-draining deck that is available in checker plate or carpeted aluminium (can also be finished in a flat-painted aluminium, ready for EVA marine flooring).

Formosa has designed a large drain channel welded in each corner of the transom which drains the water from the deck, through a v-cleat scupper system. It’s what Formosa calls a ‘TRUE’ self-draining deck as the drainage system sits ABOVE the waterline, allowing the water to leave the boat. This is thanks to Formosa’s hull design which allows for a high floor that sits above the chine line or water line. Other ‘draining decks’ on the market are welded below the waterline, and so direct the water into the hull requiring the water to be pumped out of the boat; a scary proposition if the bilge pump is out of action.

For peace of mind, every Formosa hull is foam filled and an underfloor bilge pump is fitted as a standard feature.
