Small Craft Design Review & Optimization
Review and optimize small craft designs with expert naval architecture guidance
What You Can Do
You get expert design critique and optimization recommendations for small watercraft projects, from initial concept sketches to detailed plans. Claude analyzes your designs for hydrodynamic efficiency, structural integrity, material optimization, and buildability, then provides specific improvements to reduce weight, improve performance, and ensure seaworthiness.
Features
Evaluate hull shapes, waterline transitions, and drag characteristics to optimize speed and fuel efficiency for your design parameters
Assess framing, longitudinal stiffness, and load distribution to ensure safety and durability under operating conditions
Recommend material choices (marine plywood, composite, fiberglass, aluminum) based on weight, cost, durability, and maintenance requirements
Review construction sequences, joinery details, and assembly methods to simplify the build process and reduce errors
Calculate stability metrics, trim characteristics, and expected speed ranges for different displacement and power scenarios
Identify opportunities to reduce material waste, simplify construction, and optimize labor requirements without compromising quality
Verify designs meet relevant standards for stability, freeboard, and safety equipment based on vessel size and intended use
Example Output
Example 1: 22-foot Sailboat Hull Review
Analysis shows overly deep keel (recommend reducing draft by 6 inches) while maintaining stability. Hull form exhibits high prismatic coefficient (good for cruising) but wave-making resistance could drop 8-12% with softer bow entry. Recommend: reshaped stem, modified waterline beam aft, and reduced overall weight through composite mast step.
Example 2: Fishing Boat Build Optimization
Current plan uses excessive framing intervals (16 inches). Recommend 20-inch spacing with slightly heavier longitudinals - saves 200 lbs, simplifies assembly, maintains full strength. Plywood thickness recommendations: bottom 3/8" (adequate), topsides 1/4" (reduce from 3/8"), cabin front 3/16" (thin enough, simplifies bending). Material savings: 15%, labor savings: 20 hours.
Example 3: Stability and Safety Audit
For proposed 19-foot recreational cruiser: Metacentric height 2.1 feet (borderline, recommend 2.4+ for comfort). Current freeboard at bow 3.2 feet (marginal, increase to 3.8 feet). Weight analysis shows 200 lbs of excess topside structure that can be eliminated through redesigned cabin windows and compartment lids. Revised design improves seaworthiness and reduces seasickness risk significantly.
