Where the joy lives

Modern Swift Trawler efficiency. Slow is the point — coastal loops and coffee at idle; systems complexity and dockage are the burden.

  • coastal cruising
  • passage

Watch-outs

Honest watch-outs — so more days feel like why.

  • bottom-paint
  • insurance-hard
  • slip-required
  • tow-vehicle-3/4-ton
  • winterize-complex

Common watch-outs

  • Diesel heat-exchanger and raw-water corrosion
  • Window gasket and pilothouse leak paths
  • Tankage odor and waste-system neglect
  • Stabilizer / thruster hydraulic leaks
  • Bottom paint and zinc schedules if kept wet year-round
  • Low-hour but calendar-aged engines and gensets

Safety notes

  • Slow-speed collision avoidance and radar/AIS watchkeeping matter more than horsepower.
  • Practice anchor drills; trawler crews live on ground tackle.

Demo estimate

Educational snapshot so surprise spend doesn't steal boat days — not a quote, not the reason you're here.

Educational demo estimate from trawler · ~36 ft · inboard. Assumes 50 engine-hours/yr, wet-slip, sunbelt, 5-year hold. Boat day proxy = engine-hours ÷ 4. Not a quote, appraisal, or underwriting offer. Dockage, haul-outs, diesel service, and systems dominate. Fuel burn is modest vs planing cruisers; time at the yard is not.

Maintenance rhythm (clear the deck)

  • Engine oil and filters

    ~100h / ~12 mo · Diesel or gas per OEM; calendar matters on low-hour boats.

  • Raw-water impeller(s)

    ~100h / ~12 mo · Include generator if equipped.

  • Cooling system / heat exchanger service

    ~24 mo · Saltwater intervals shorter; zincs more often.

  • Shaft seal / stuffing box / dripless check

    ~6 mo · Monitor for excess drip or overheat.

  • Seacock and hose clamp survey

    ~12 mo · Below-waterline risk items.

  • Winterize engines, plumbing, and A/C

    ~12 mo · Freeze-belt mandatory; include heads and water heaters.

  • Stabilizer / thruster service (if equipped)

    ~12 mo · Hydraulic leaks and anode wear common.

  • Ground tackle and windlass service

    ~6 mo · Passage makers live on their anchors.

Extra common issues

  • Diesel contamination
  • Cutless bearing wear
  • Cabin leaks

Survey focus

  • Fuel system
  • Shaft/packing
  • Moisture cabin

Campaign / bulletin diligence

  • Educational: Rigging + keel/structure + systems survey for cruising sailboats.
  • Educational: oil analysis + fuel samples are high-ROI for diesel trawlers.
