The thinking behind our boats

JK Labs


From the previous inputs and further discussions with you on significant goals, such as draft limitations, canting or lifting keels, size, or budget, this INITIAL BRIEF is produced to DEFINE YOUR WAY OR SAILING!

The brief spells out the preliminary characteristics of the boat, in terms of key dimensions, underwater appendices, rig, deck layout, systems, and accommodations: the real design process can start from there.

It is not a sequential process but a one that needs at least 2 completed loops, in the 4 main fields of expertise:

Concept and Design: “where the main parameters and the style are balanced”

Engineering and structures: “where the balance between weight and resistance are calculated, as well as the needed systems”

Naval architecture & Performances prediction: “Balance, stability, flotation etc. all the pure naval architecture characteristics are measured and predicted”

Specifications and drawings: “All the 3D and 2D drawings/models needed by the boat builder, materials and systems suppliers to bring the whole package together. Between equipment lists, piping diagrams, hydraulic schematics, electrical drawings, instrumentation diagrams, and detailed component specifications, we are looking at hundreds of engineering/design documents, each of them critical to the success of the project.”

This Design Spiral process, which involves several revisions/validations and a lot of work for our people, enables us to converge to a solution where the target performance, weights, and structural requirements have been thoroughly validated.

During this process, we gave you and your project manager the opportunity to give input at several key moments.

Juan-K office will assist you in picking the right construction team and suppliers.

Initial brief and design/ engineering process

At Juan-K, we have learnt that the people who own and sail our designs, who are themselves successful and busy people, need to tell us what they are really after before we put the pencil on paper, connect the computer and get the team to work. For this, we have to ask you the right questions.

Our first mission is to guide you through a challenging initial brief. The challenge will be for you to choose how you wish to balance several pairs of mutually exclusive parameters.

And to this end we will use what we call the “Ratiography”, an interactive graph that enables you to do just that: choose!

Cruise vs Race: How do you intend to use your boat, from racing only to cruising only, or a mix?

Freedom vs Rule: captures whether you wish the boat to be designed specifically to a rule, or you are happy to sail with a boat that is not rule-specific.

In between, you might want to consider a boat that measures reasonably well under several rules, so you can race in a variety of events.

Offshore vs Inshore: Is the boat intended for blue water sailing or for coastal sailing? In terms of features, draft, stowage areas, tankage, the requirements are very different.

Classic vs Modern: Do you want your boat to defer to tradition, or you are ready to go for a fully contemporary design? Or do you want a boat that looks like a classic but works like a modern boat?

Fine-Tune & Performance Tracking

fine-tune & performance tracking

Properly commissioning a complex yacht is critical to its later life, but the next task is to make sure that the performance.

We will check that the many systems are operated properly, and that the structure of the vessel is operating within its design parameters. Juan-K Labs offers this service, whereby the owner will be periodically updated on the ‘health” of his yacht, based on data logged on board with the input of the appropriate instrumentation. Targeted inspections and evaluations can be triggered by this process, a fundamental piece of an effective preventive maintenance program, and ultimately, of the long term success of your yacht.

We believe that you should get the boat you wanted, use her intensively and keep her in top condition. Count on us to assist you!

This is what we do at Juan-K Labs.
