• Teak removal and deck-core reconstruction

  $25k–$95k

  40% likelyexpected $22kinferred

• Chainplates, studs or supporting knees require structural replacement

  $8k–$30k

  45% likelyexpected $7kinferred

  Reasoning, not a source: Early Tayana chainplates penetrate the deck and can leak into concealed timber-backed attachment structures. The listing gives no replacement evidence.

• Original black-iron fuel or water tanks require replacement

  $10k–$38k

  65% likelyexpected $14kinferred

  Reasoning, not a source: The 1979 boat falls squarely within the original black-iron-tank era, and no replacement is disclosed. Custom cabinetry may need extensive removal.

• Perkins requires overhaul or complete repower

  $14k–$42k

  35% likelyexpected $9kinferred

• Bowsprit, sampson posts, bobstay or associated structure is rotten or fatigued

  $6k–$22k

  35% likelyexpected $4kinferred

  Reasoning, not a source: The design carries forestay loads through substantial exposed timber and metal fittings. The listing photograph shows aged exterior timber but cannot establish structural condition.

• Bulkhead tabbing or compression structure has water damage

  $7k–$35k

  30% likelyexpected $5kinferred

  Reasoning, not a source: Deck and chainplate leaks can reach structural timber hidden behind extensive interior joinery.

• Osmotic blistering or prior grounding damage requires laminate work

  $5k–$30k

  25% likelyexpected $4kinferred

  Reasoning, not a source: This is a 47-year-old fiberglass hull with no haul-out photographs, survey history or grounding disclosure. Heavy solid laminate reduces structural concern but not repair cost.

• Embedded stern-tube fasteners or shaft hardware require reconstruction

  $5k–$20k

  20% likelyexpected $2kinferred

  Reasoning, not a source: Tayana owner documentation describes inaccessible embedded stern-tube fasteners that can break during ordinary bearing work.
