Designing Procedure for Charter Boat/Yacht: A Naval Architect’s Perspective

Charter Boats have key significance in the domain of marine tourism and coastal recreation, offering from breathtaking views of the ocean to exhilarating sports fishing adventures.

But such experience lies in a well-thought-out engineering process by the expertise of a Naval Architect.

Are you looking for Naval Architects’ services?

 At Architects of the Sea, we specialize in turning functional requirements into safe, efficient, and elegant Boat/Yacht designs.

In the procedure, the first & foremost steps are to

1.   Define the Mission

Every design starts with a clear mission profile. We, as a Naval Architect Firm, ask you these questions to understand your aim and design preferences.

• Will it be used for fishing, tourism, diving, or a combination? – To understand the mission
• How many passengers should be onboard? – To ensure services to all passengers
• What kind of amenities are available? – To understand Design Considerations
• At what location will you operate? – To understand sea conditions (Calm or Rough)

Note: We may ask more Questions!

This brief helps to understand & shape the rest of the design process, ensuring that the vessels meet both operational and comfort requirements under specific Compliance/ Standards.

2. Choosing a Suitable Hull Form

The selection of Hull Form, we may call it the Main Body of the Boat, influences performance and fuel efficiency.

There are multiple types of Hulls utilized for specific scenarios and requirements.

• Displacement Hull: ensure maximum load carrying capacity and operate at low speed up to 10 knots.
• Semi Displacement Hull: offers better load-carrying ability, but for speeds of 10 knots- 25 knots
• Planing Hull: Suitable for High-Speed Yachts, Sports Fishing, and fast-moving operations.

These Hull types, mentioned above, have further divisions, such as a planning hull could be a single chined hull, a doubled chined hull, a single/double chined hull with spray rails, a stepped Hull with single/Double Chined Hull with/without spray rails.

3.   Layout & General Arrangement

A well-thought-out deck layout, machinery room layout enhance both usability and passengers’ comfort.

• Helm Station: To ensure ergonomic controls
• Seating: To ensure a good, comfortable journey with storage below
• Piping & Plumbing Network: To ensure smooth operational activities.
• All Other Important Items need to be there: Toilet, Sleeping space, Live wells, etc.

All designs comply with internal safety standards (e.g, ISO 12217) to ensure adequate stability, buoyancy, and evacuation routes.

4.   Analysis Phase

Behind the Design, a deep layer of Naval Architectural Analysis needs to be performed to ensure the vessel is safe, stable, and performs as expected. Here’s what we typically assess:

• Hydrostatics: To evaluate its water submergence, displacement, draft, LCF, etc.
• Equilibrium: To ensure its longitudinal and transverse balancing of the vessel
• Stability: To ensure that it can sustain waves to stand still in the ocean.

We may perform other analyses such as longitudinal pressure calculation, limited KG, etc. All designs comply with internal safety standards (e.g., ISO 12217, HSC, etc.) to ensure adequate stability, buoyancy, and evacuation routes.

5.   Structure & Material

We design & Calculate the Hull Thickness and Internal Structure/Scantling using marine-grade material such as:

• Fiber Reinforced Plastic (FRP): Lightweight, durable, and cost-effective
• Aluminum: Strong and corrosion-resistant for high-performance builds
• Steel: Stronger than any other material to ensure the strength of the boats/yachts.

Structural Components: Stringers, Bulkheads, frames – need to arrange strategically based on engineering perspective to ensure that they can sustain wave impact and support loads.

All designs comply with internal safety standards (e.g., ISO 12215, LR, DNV, etc.) to ensure adequate strength and safety factor.

6.   Compliance & Construction TDP

 We prepare detailed 2D and 3D Construction Drawings ready for shipyards, fabricators, and Compliance Approval activities.

• General Arrangements Plans
• Hull Lines
• Framing and Bulkhead layouts
• Electrical & Plumbing Schematics

Our boats are designed by local/international maritime regulations, including life savings, fire safety, and pollution prevention standards.
