Hauling the sailboat provides access to areas such as:

  • Underwater hull

  • Keel

  • Keel-to-hull joint

  • Rudder

  • Propeller

  • Shaft

  • Strut where applicable

  • Saildrive or outdrive where equipped

  • Through-hulls

  • Transducers

  • Anodes

  • Underwater damage

The marina or boatyard normally performs the haul-out while the marine surveyor conducts the inspection.

Sailboat Sea Trials

A sea trial can provide additional information regarding vessel operation.

Depending upon scope and conditions, observations may include:

  • Auxiliary engine performance

  • Steering

  • Controls

  • Instrumentation

  • Vibration

  • Operating temperatures

  • Navigation electronics

  • Autopilot

Chicago & Lake Michigan Sailing Market

Chicago has a substantial concentration of sailing vessels located along the city's Lake Michigan waterfront.

Great River Marine Surveying provides sailboat inspection services for vessels located throughout the Chicago harbor system and surrounding Lake Michigan communities.

Assignments may be coordinated at or near:

  • Burnham Harbor

  • Belmont Harbor

  • Montrose Harbor

  • DuSable Harbor

  • Monroe Harbor

Our sailboat surveying coverage can extend north from Chicago to established Lake Michigan sailing communities.

Depending upon scheduling and vessel location, coverage may include:

  • Evanston

  • Wilmette

  • Winnetka

  • Glencoe

  • Highland Park

  • Lake Forest

  • Waukegan

  • Winthrop Harbor

This complements your existing Chicago and dedicated North Shore location coverage without requiring separate keyword pages for every individual type of sailboat survey.

Great Lakes Sailboat Considerations

Sailboats operated on Lake Michigan experience conditions that differ from vessels in year-round warm-water markets.

Important considerations may include:

  • Seasonal use

  • Winter lay-up

  • Freeze protection

  • Mast stepping and unstepping

  • Seasonal rigging setup

  • Moisture intrusion

  • Corrosion

  • Aging rigging

  • Deck hardware leakage

  • Keel and rudder condition

  • Machinery winterization

  • Battery storage

  • Deferred maintenance

Winter storage can also provide excellent access for certain hull, keel, rudder and rigging inspections.

Surveys While the Mast Is Unstepped

One of the best opportunities to inspect normally inaccessible upper rigging can occur when the mast has been removed for winter storage or maintenance.

With the mast unstepped and safely accessible, additional components may become available for visual examination, including:

  • Spreaders

  • Upper terminals

  • Masthead fittings

  • Tangs

  • Stay attachment points

  • Mast wiring

  • Navigation-light fixtures

  • Other upper-rig components

Your company's published rigging scope specifically notes that spreaders, tangs and upper rigging can be evaluated when the mast is unstepped or otherwise made accessible.

Rigging Surveys for Insurance

Owners of older sailboats may occasionally be asked by an insurance company to provide information regarding the age or observed condition of standing rigging.

A focused rigging survey can document accessible rigging components at the time of inspection.

Great River Marine Surveying's published rigging service identifies insurance underwriting and renewal as one of the common reasons clients request rigging inspections.

Rigging Surveys for Pre-Purchase Buyers

A buyer considering an older sailboat may wish to supplement a comprehensive pre-purchase marine survey with a more focused evaluation of the vessel's rigging and sails.

This can be particularly valuable when:

  • Rigging age is unknown

  • Replacement history is unavailable

  • Corrosion is visible

  • The vessel has been stored for an extended period

  • The boat has experienced a previous rigging failure

  • Significant offshore or heavy-weather use is planned

  • The sail inventory represents substantial replacement cost

The inspection can help the buyer better understand observable rigging and sail condition before closing.

Following the inspection, Great River Marine Surveying prepares a professional written marine survey report.

Depending upon the assignment, the report may include:

  • Vessel identification

  • Vessel specifications

  • Photographic documentation

  • Hull observations

  • Structural observations

  • Deck observations

  • Rigging findings

  • Sail observations

  • Machinery observations

  • Electrical observations

  • Safety-equipment findings
