Potentially affected areas may include:
Hull sides
Bow
Stern
Transom
Rub rails
Deck structure
Bulkheads
Stringers
Railings
Windows
Interior components
Steering equipment

A focused inspection can document observable damage and help determine what areas may require additional examination or repair evaluation.
Allision Damage Surveys
An allision occurs when a vessel strikes a stationary object.
Examples may involve contact with:
Docks
Piers
Pilings
Seawalls
Breakwalls
Fixed navigation structures
Harbor structures
Other stationary objects
Allision damage may range from cosmetic abrasion to significant structural damage.
Great River Marine Surveying can independently document the vessel's observable condition following the incident.

Groundings and submerged-object strikes can affect portions of a vessel that cannot be properly evaluated while the boat remains afloat.
Potentially affected areas may include:
Hull bottom
Keel
Propellers
Shafts
Struts
Rudders
Sterndrives
Outboard lower units
Trim tabs
Through-hulls
Transducers
Structural components
An out-of-water inspection is generally recommended when grounding or underwater impact damage is suspected.
Propeller & Running Gear Damage
Propellers and underwater running gear may be damaged by:
Grounding
Submerged debris
Fishing line
Floating objects
Docking incidents
Improper lifting
Other underwater impacts
Depending upon vessel configuration, the surveyor may inspect accessible:

Fiberglass cracking
Hull abrasion
Rub-rail damage
Rail damage
Cleat damage
Deck cracking

Prompt inspection can help preserve evidence before cleanup or repair changes the vessel's condition.
Submersion Damage Surveys
A partially or fully submerged vessel may sustain extensive damage.
Areas potentially affected include:
Propulsion machinery
Fuel systems
Electrical systems
Batteries
Navigation electronics
Generators
Interior furnishings
Safety equipment

Vessel identification
Detailed photographs
Damage descriptions
Location documentation
Observable condition information
Measurements
Machinery observations
Structural observations
Other factual findings
Our Chicago-region service offering already includes Damage & Insurance Claim Surveys, establishing this as an existing company capability rather than a new or unrelated service.
Damage Surveys for Boat Owners
Boat owners may independently request a professional damage survey after a casualty.
Reasons may include:
Insurance documentation
Repair planning
Determining apparent extent of damage
Documenting condition before repair
Disputes regarding responsibility
Transportation claims
Marina-related incidents
Legal matters
Owners should preserve relevant photographs, damaged components, invoices and incident documentation whenever reasonably possible.
Damage Surveys for Attorneys
Attorneys may require independent marine documentation involving:
Collision disputes
Insurance disputes
Repair disputes
Transportation claims
Marina incidents
Property damage
Commercial vessel casualties
Other marine matters
The requested scope should be established before inspection when the report is intended for litigation or another legal proceeding.
Repair Facility Documentation
Marine repair facilities may also benefit from independent documentation before extensive repairs begin.
A survey may establish:
Vessel condition on arrival
Observable casualty damage
Damaged components
Photographic evidence
Areas requiring further investigation
Conditions encountered during inspection
Once damaged components are dismantled or discarded, important physical evidence may no longer be available.
Repair Estimates & Additional Specialists
Depending upon the assignment, repair cost information may require estimates from qualified repair yards, mechanics, electricians, riggers or other specialists.
A marine damage surveyor may identify affected components and document damage, while detailed repair methodology or engineering calculations may require:
Marine repair yards
Engine technicians
Marine electricians
Naval architects
Fiberglass specialists
Welders
Rigging professionals
Manufacturer representatives
The final scope depends upon the complexity of the casualty.
Time-Sensitive Damage Inspections
A marine casualty should often be documented as soon as practical.
Important evidence may change once the vessel is:
Moved
Hauled
Cleaned
Dried
Dismantled
Repaired
Salvaged
Modified
Damaged components may also be discarded during repair.
Prompt inspection can help create an independent record before those conditions change.
Photographic Marine Documentation
Photographs are an important part of damage-survey reporting.
Depending upon the casualty, documentation may include:
Overall vessel views
Damaged areas
Close-up photographs
Context photographs
Machinery
Electrical equipment
Structural components
Running gear
Identification numbers
Other relevant evidence
Photographs help provide insurers, vessel owners, attorneys and repair facilities with a visual record of conditions observed during the survey.
Out-of-Water Damage Inspections
Certain casualties require access to underwater components.
Haul-out should be considered following suspected:
Grounding damage
Propeller strikes
Shaft damage
Rudder damage
Hull-bottom impact
Sterndrive damage
Keel damage
Underwater collision
The boatyard or marina normally performs the physical haul-out while the marine surveyor conducts the inspection.
Milwaukee & Western Lake Michigan Coverage
Great River Marine Surveying provides damage and claim survey coverage throughout the greater Milwaukee and western Lake Michigan boating market.
Inspections may be coordinated for vessels located:
At marinas
At boatyards
At repair facilities
In winter storage
At dealerships
At commercial facilities
Afloat

On trailers or stands
Your established Chicago service territory already specifically includes all Racine and Milwaukee marinas and advertises damage and insurance claim surveys.
Milwaukee's Boating & Charter Market
The local market includes recreational powerboats, sailboats, fishing vessels, yachts and commercial charter boats.
McKinley Marina, Milwaukee County's public lakefront marina, maintains 655 slips and lists a large number of fishing charter operators as well as sailing, diving and recreational charter services.
That combination creates potential damage-survey demand involving both private recreational vessels and qualifying commercial craft.
Seasonal Lake Michigan Considerations
Milwaukee vessels experience seasonal conditions that can contribute to marine losses and maintenance issues.
These can include:
Severe thunderstorms
High winds
Wave action
Winter freeze
Snow and ice
Seasonal haul-out
Winter storage
Spring launching
Corrosion
Moisture intrusion
Deferred maintenance
Damage may therefore occur both during the boating season and during winter lay-up.
