Propellers: One Size and Shape Does Not Fit All
Hydrocomp’s newest release of PropCad incorporates 3 years of enhancements. Propellers are surprisingly complex devices, especially considering most are a solid piece of metal with no moving parts. The variation in vessels and operational requirements leads to wildly different designs, from noise-sensitive propellers for luxury cruiseliners to wide-blade sets for tugs. With different combinations of diameters, pitches, blade styles, and blade counts, there is no limit to the design alternatives available.
Long Serving Charity Employees Reminisce
Two employees of one of the U.K.’s oldest maritime charities have been reminiscing after celebrating a collective 80 years of service at the Royal Alfred Seafarers’ Society.

HydroComp SwiftCraft 2009 Adds Features
SwiftCraft is a designer's tool for speed and power prediction of propeller-driven monohull vessels under 250 ft. SwiftCraft had been developed specifically for designers and builders of motor yachts, patrol craft, small ships, supply vessels, ferries and other transit craft. SwiftCraft employs advanced parametric prediction capabilities. Modeled on web navigation, it is ideal for new users where a rapid learning curve is important and the time needed to complete a project must be minimized. • New report viewer - A new integrated report viewer provides enhanced reporting options, including direct to PDF, as well as export to RTF (for word processing) and CSV (for spreadsheets). • Effect of shaft angle - High shaft angles can greatly affect a propeller's thrust and torque.
Is 3-D Product Modeling Practical For Small U.S. Shipyards?
Over the past 30 years, computer-aided ship design and construction has progressed from mainframe computers to PCs, from independent programs to fully integrated programs, and from large shipyards to all sizes of shipyards. More to the point, key advances during the past several years have made 3-D product modeling a tool that can significantly improve small yard efficiency, quality, and profit. However, 3-D product modeling can do these things only if implemented in a planned and well thought-out manner, tailored to the specific yard. 3-D product modeling, when combined with other innovations such as NC production equipment and the workstation approach to production…
