Inspection

Inspector Detail

Common issues

  • On-load release hook mechanism seizing or falling out of adjustment if not exercised regularly
  • Hydrostatic release unit reaching its marked expiry date unnoticed
  • Hull gelcoat cracking or delamination from UV and weather exposure
  • Engine starting failure from battery or fuel degradation during long periods of infrequent use
  • Painter/release wire corrosion or fraying

Inspection checklist

  • Monthly visual inspection of the launching appliance and release gear (SOLAS III requirement)
  • Annual thorough examination by an approved service provider
  • On-load release gear overhaul on the maker/SOLAS-driven schedule
  • Hydrostatic release unit expiry date check
  • Engine start and cooling-water discharge test
  • Skid/ramp and free-fall launch structure condition check

Service intervals

Annual servicing by approved LSA service station12 months
On-load release gear overhaultypically every 5 years - confirm against the maker's schedule
Hydrostatic release unit replacementper the unit's marked expiry, commonly every 2 years
Boat engine serviceper maker's schedule, checked at each annual service

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Critical spares

  • Hydrostatic release unit (approved matching type)
  • Release hook/gear overhaul kit
  • Engine starting battery
  • Painter line
  • Engine fuel filter and raw-water pump impeller

Safety

  • On-load release gear must only be exercised under a controlled, supervised procedure - never with personnel aboard outside an approved drill
  • Free-fall launch generates high deceleration loads - seating and restraint integrity is safety-critical
  • Engine exhaust and battery gassing risk in an enclosed boat compartment

Class survey

Covered by LSA (Lifesaving Appliances) survey requirements: annual thorough examination and 5-yearly overhaul/load test of the release gear, with certificates from the approved service provider kept in the ship's LSA maintenance file. Note: available source data for this entry is limited - verify make/model-specific details against the vessel's own equipment manual before relying on them operationally.

Estimated lifetime: Not meaningfully expressed in running hours; SOLAS free-fall lifeboats of this class are typically given a design service life in the order of 20-25 years, subject to annual and 5-yearly servicing - confirm against the vessel's LSA maintenance record and the equipment's own type approval documentation.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
