Marine structures must efficiently withstand the day to day operational loads experienced by the vessel as well those encountered under extreme conditions; all the while working in concert with all other ship systems. Type of vessel, operational parameters, construction methods, and choice of materials are a few of the many variables which come into play when developing such a critical component of a vessel's design.

Lightweight, strong structure is important; especially in high speed designs. DLBA excels in producing structural plans which provide superior operability, comfort, and safety. With a myriad of tools and many years of experience to draw from, the engineers and designers at DLBA produce structural designs for custom cold molded yachts, production boats, large motor yachts, commercial, and military vessels constructed of wood, composites, aluminum, and steel. From Douglas Fir to infused carbon fiber, DLBA is proficient in developing efficient, robust plans which can help to maximize interior space while meeting structural requirements and minimizing weight.

While employing field tested, in house structural standards, DLBA is also familiar with, and has designed to classification society rules such as DNV, ABS, and Lloyd's Register as well as ISO/CE.

Finite Element Analysis, or FEA, is another tool DLBA uses regularly to aid in overall vessel structure as well as development of individual structural components including titanium engine foundations, composite keel attachments, and carbon fiber waterjet inlets.
