Vessel Stability Assessment

Independent 5-Layer Engineering Analysis — Written Report, Actionable Recommendations, No Sales Agenda

Starting at $2,500

What You Get

Before spending $15,000–$150,000 on a stabilization system, know exactly what your vessel needs. Our independent assessment prevents costly mistakes and identifies optimizations you didn't know existed.

Core Principle: We don't sell stabilization systems. We engineer the right solution for your vessel — which might be installation, relocation, redesign, or nothing at all.

Client Satisfaction
"We were quoted $45,000 for a gyro install. UpgradeGyro's assessment showed our hull didn't need one — interceptor fins were the right solution. Saved us $35,000 and the boat rides better than ever."

"The power audit revealed our 'battery problem' was actually an alternator + wiring problem. $3,200 fix instead of the $12,000 battery replacement we were quoted. The report paid for itself 3x over."

Risk Reversal — You Have Nothing to Lose

100% SATISFACTION GUARANTEE

If Our Assessment Doesn't Provide Actionable Value, We'll Reassess for Free

We're that confident in our process. If you don't receive at least one insight that saves you money or improves performance, we'll return and reassess at no charge.

No obligation. No sales pressure. No follow-up harassment. If you never hire us for implementation, that's fine — the report is yours to use with any yard or installer you choose.

⚡ Limited Assessment Slots — Book Now

We conduct a maximum of 8 comprehensive assessments per month to maintain quality. June slots are 75% booked. September–October (peak refit season) books 6–8 weeks in advance.

What Your Report Looks Like

Every assessment produces a professional engineering report you can use for insurance, resale, or yard coordination:

📋 Executive Summary (1–2 pages)

Decision-ready overview with recommended path, estimated investment, and expected outcomes. Written for owners and captains — no engineering degree required.

📊 Technical Findings (Scored Analysis)

Each of the 5 layers rated against best-practice benchmarks. Color-coded: green (good), yellow (needs attention), red (critical). Photos and data included.

🗺️ Structural & Electrical Diagrams

Annotated photos of foundation, stringers, and installation. Electrical schematic showing load paths, breaker sizing, and recommended upgrades.

📈 Option Matrix with Cost Ranges

2–4 viable paths ranked by performance, cost, and complexity. Each includes: investment range, timeline, risks, and our recommendation with rationale.

🔧 Implementation Timeline & Vendor List

Realistic scheduling with yard coordination notes. Suggested vendors and parts list. Maintenance roadmap with service intervals and cost projections.

What's Included in Every Assessment

1

Hull Behavior Analysis

Natural roll period, damping characteristics, and sea-state response. We determine whether your hull even needs stabilization — some don't.

2

Weight & Center of Gravity

Dynamic loading scenarios, tank effects, equipment placement, and vertical CG impact. Where the gyro sits relative to CG determines 60% of performance.

3

Structural Capacity

Foundation design validation, stringer alignment, load path continuity, and fatigue analysis. We identify cracks before they become failures.

4

Power System Architecture

Battery capacity under load, alternator output curves, genset transient response, and wire sizing. Most gyro failures are electrical, not mechanical.

5

Control Integration

NMEA 2000 network load, autopilot interaction, trim system coordination, and operator training requirements.

Deliverables

Every assessment produces a comprehensive written report including:

Insurance Value: Our reports are accepted by marine insurers and surveyors as third-party engineering documentation. Useful for claims, pre-purchase surveys, and resale.
