Walworth Yacht Designs
Naval Architecture and Marine Engineering
Services
In addition to overall boat design, Walworth Yacht Designs can supply other key services.
- Stability Analysis: The stability characteristics of any boat are important, and WYD can provide this service for all boats.
In addition, part of receiving a Certificate of Inspection to operate a commercial boat in US waters is obtaining a stability letter.
Calculating the stability of the boat requires familiarity with the USCG regulations coupled with sound naval architectural knowledge.
The tool we use is GHS, specialized software developed to analyze the hydrostatic characteristics of boats, both intact and damaged.
This is the same software used by the USCG and many other government agencies and naval architecture firms, so compatibility of the
computer models is assured. WYD has much experience with the procedures, helping to streamline the process. As David is a
licensed Professional Engineer in Naval Architecture and Marine Engineering, there is the added benefit of being able to take advantage
of the P.E. expedited review procedure at the USCG.
- Structural Design: WYD can engineer the structure from an existing conceptual design; see Abigail, for example.
It is also not uncommon that the owner of an existing boat will want to make changes that require engineering design.
This is another service WYD provides. For example, the owner of a large catamaran here on St. Croix wanted to add a small
aft deck and crane for the dinghy. WYD engineered the laminates for the new aft deck and the installation of the crane.
- Boat parts: In many ways a subset of the structural design services, the design of individual components for boats
is another service. Examples of this include rudders, daggerboards, passerelles, trim tabs, etc.
- Structural analysis: WYD has supported surveyors and provided analyses and guidance for sound repair of damaged boats.
