Behind this relatively simple component lie several technical challenges, including ensuring proper drainage, minimizing water ingress, and reducing installation time on-site.
Reduce installation time on-site
Waterfall's primary objective relates to the setup phase.
In the threaded version, the valve and the hose fitting can be assembled before installation on the boat. This preparation allows a single operator to perform the installation while minimizing the number of steps required on board.
For both construction sites and refit shops, this approach helps reduce turnaround times and the risks associated with improper assembly of the various components.
A design specifically engineered to promote drainage
The hydraulic design is the second technical feature of the system. Osculati specifies a 13° drainage angle, designed to promote natural water flow while minimizing siphoning effects that can slow down cockpit drainage.
The system also includes a check valve designed to prevent water from flowing back into the boat when reversing or when the stern dips below the surface due to waves.
These characteristics directly apply to motorboats as well as sailboats equipped with drain lines that pass through the transom.
Two configurations to accommodate common setups
The product line consists of two versions to accommodate the most common installations. The first features a 38 mm hose connection. The second uses a 1½-inch thread with a built-in check valve.
Both models are compatible with transom boards ranging in thickness from 10 to 60 mm. They feature a 36 mm clear passage diameter, a size suitable for many configurations found on recreational boats.
Materials Suitable for the Marine Environment
As with all hull through-hull fittings, corrosion resistance remains a key consideration. The outer part is made of stainless steel and is secured with countersunk screws to minimize rough edges on the transom while maintaining a clean finish.
Beyond aesthetic considerations, the choice of materials is intended to maintain the system's performance despite constant exposure to seawater and the rigors of navigation.
With Waterfall, Osculati rounds out its lineup of technical components designed for boat builders and marine industry professionals. This new line is part of an effort to simplify installation while providing technical solutions for water flow management?an area where the reliability of equipment remains a key factor in the safety and longevity of boats.
