The actual cash value is the value that our research approximates the selling price of this vessel should be, at the time and place of our inspection.  Consideration is given to vessel’s condition, geographic location, published listings and guides, comparable sales and listings, and market conditions.  The new replacement value is the cost of this or a similar, new vessel, comparably equipped.  The investment is the reported investment including purchase price and significant upgrades.  No values include maintenance costs, storage or tax.  The most relevant data found while researching the value is included below.  We primarily use market value analysis methodology for determination of value.


Explanation of value opinion: The average historical sale price of similar vessels on soldboats.com is $97,593 and the average current listing price of similar vessels on Yachtworld.com is $139,096.  The vessel is in above average condition for its age and has significant upgrades.  There is currently a Covid-19 related demand and value spike and it is unclear as to how long this demand spike will last.  This spike, the upgrades and the condition of the vessel have been factored into our valuation of the vessel.

These recommendations are the surveyor’s ideas and suggestions for addressing deficiencies with damaged or suspect components or systems found during survey or general improvements.  The primary recommendations address safety items, structural issues, operational issues or deficiencies which the surveyor determines are of greater importance or more expense than secondary deficiencies.  For instance, items that pose a risk to passenger safety or immediate property damage are listed under primary deficiencies and cosmetic concerns are addressed under secondary deficiencies.  Most of the recommendations have been addressed in the comments and usually they are discussed at the time of the inspection.



  1. Maintain the fixed and portable fire extinguishers per NFPA recommendations.  Extinguishers should be inspected and tagged annually and inspected by a qualified technician or replaced every six years.
  2. Display the documentation number per federal regulations.
  3. Determine why the HIN does not follow proper format and address appropriately.
  4. Determine why the engine does not turn to its designed rpm specifications and address appropriately.
  5. Service or replace the audible engine alarm and prove it properly functional.
  6. The galley sink’s raw-water intake through hull valve leaked when opened and continued to drip after closing.  Service the through hull and valve and prove it properly functional and eliminate the leak, clean and dry the bilge space to allow detection of future weeps or leaks.
  7. Properly secure the ground wire that is loose aft of the transmission.
  8. No identification was seen on the fuel fill hose.  Determine the suitability of the hose for continued use and replace if / as necessary.  The industry life expectancy of fuel hoses is ten years
  9. We strongly recommend the installation of a carbon monoxide alarm, smoke alarm and LP alarm.
  10. The standing rigging is reportedly original.  A rigging survey was performed on December 2, 2020.  Follow the recommendations of the rigging survey.
  11. The cotter pins are missing on the baby stay’s turnbuckle.  Install new pins.
  12. The pull / kill cable is a bit stiff.  Service the pull / kill cable to allow ease of use.
  13. Replace the broken mounting bracket on the fuel filter on the engine.
  14. There is corrosion weeping around the base of the rudder port.  Determine the cause of the weeping, address appropriately/eliminate the cause and clean the area to allow detection of any future weeps or leaks.
  15. The starboard aft motor mount is missing a washer.  Replace the washer.
  16. There is light corrosion on the engine’s heat exchanger.  Determine the cause of the corrosion, eliminate the cause, address any deficiencies and clean the heat exchanger to allow detection of future weeps or leaks.
  17. There is minor rust on the starter, address any damage, eliminate the cause and clean to allow detection of future issues.


  1. Address the fastener holes in the headliner to starboard aft in the saloon as desired.
  2. Address the spider cracking to starboard on the upper part of the transom as desired.
  3. Determine why the burners and broiler are not thermo-coupled on the galley range and address as necessary.
  4. Address the repair / color differences to port forward, starboard forward and starboard aft in the cockpit as desired.

  6. Replace the missing Vetus ventilation duct on the forward dorade cap.
  7. Address the spider cracking on the starboard hull side below the toe rail at the boarding gate as desired.
  8. Address the cracking on the interior of the starboard cockpit locker by the hinges as desired.
  9. Address the color difference on the starboard hull side forward approximately three feet aft of the bow and above the boot stripe as desired.
  10. Address the rub damage on the starboard hull side forward between the boot stripes as desired.
  11. Address the scratch in the port hull side approximately one foot above the boot stripe between the third and fourth stanchion posts as desired.
  12. Address the color difference on the bow as desired.
  13. Equipment has been removed from the headliner at the navigation table and fastener holes remain.  Address as desired.
  14. One latch is bent and one latch is missing on the refrigerator in the galley.  Replace as desired.
  15. Replace the missing fastener from the grab rail in the galley.
  16. A wood slat is missing between sections of headliner in the aft cabin.  Address as desired.
  17. The veneer is chipped on the saloon table.  Address as desired.
  18. Address the bend to starboard on the bow rail and the scratches as desired.
  19. Determine the cause of the pitting on the propeller blades, eliminate the cause and service the propeller as necessary.
  20. A hose has been plugged below the aft berth and this hose is also cracked aft in the lazarette locker.  Replace the hose or remove it to eliminate any liabilities.
  21. There is a blower below the aft berth that has been disconnected.  Either reconnect the blower and prove it functional or remove it.
