Fabrizio Merolli

Our featured designer, Fabrizio Merolli, is a civil engineer by training. Before starting on his own two years ago, he was the chief technical officer at an Italian shipyard, which built steel fishing and work boats.

Fabrizio still designs mainly fishing vessels and work boats, but among his creations are some pleasure boats as well, such as the 20m power yacht pictured below. His design software of choice is MultiSurf which he uses very extensively indeed to design not just hulls, but the very last detail of his models. He complements MultiSurf with MSDEV and MSPLEX programs to furnish his builders with detailed nests of all the vessel’s parts. His preferred drafting program is Bentley Microstation.

Fabrizio usually begins his design with a "rough draft", which helps him to verify the model's hydrostatic characteristics and to fair the hull. At this stage, his customer can already get an idea of how the boat is going to look and have enough information in order to decide about possible changes or additional requirements. Once all characteristics have been defined and decided upon, Fabrizio designs the final model. At that point he can improve on the construction geometry, optimize the number and the kind of surfaces, organize his layers, and group the objects he wants to use for components. Finally, he adds such details as rubbing strake, bollards, rails, portholes, coaming, etc., as well as subsurfaces to represent the painting. He copies the same model many times and saves the copies with appropriate layers on in order to use them for construction plans, capacities plans, scantling plans, etc. As Fabrizio says, Relational Geometry allows him to complete these plans and make all required changes easily and precisely.

This supply ship (left - click on the thumbnail to get a larger picture) is a wonderful example of Fabrizio’s refined and detailed design. All the model’s countless details from top to bottom were designed in 3D using MultiSurf. Fabrizio takes advantage of MultiSurf’s component feature, and has built himself a library of such components as bollards, anchors, propeller nozzles, etc. Another example of skillful use of components are Fabrizio's complex and systematic scantling plans (thumbnails on right).

We are very pleased to count Fabrizio Merolli among our talented MultiSurf users. Designers like him inspire us to make MultiSurf even better. We thank Fabrizio for this opportunity to present his work, and wish him all the best in the future.
