Tartan 37 Buyer's Guide
The Tartan 37 stands as one of the more thoughtfully conceived designs to emerge from the productive Sparkman & Stephens partnership with Tartan Marine, and shopping for one on the brokerage market rewards buyers who understand what they are actually getting: a moderately heavy, moderately fast cruising boat whose reputation for holding value derives directly from quality of construction and integrity of design rather than from fashion. The model ran from the mid-1970s into the late 1980s, which means hulls on the used market today span a meaningful range of age and cumulative maintenance history. The Sparkman & Stephens pedigree produces a boat that tracks well, balances well, and inspires enough owner loyalty that the broader community — including a dedicated owners association — has accumulated substantial collective knowledge about where these boats fail and how to fix them. That community is worth engaging before you make an offer.
Layouts on the Used Market
The Tartan 37 was offered in a single basic interior arrangement that nonetheless varied in meaningful ways across the production run. The forward V-berth cabin is genuine and usable as a private stateroom, separated from the main saloon by a head to one side. The main saloon carries settee seating to starboard and a convertible arrangement to port, with a proper double quarterberth aft of the nav station — an unusually generous feature for a production 37-footer of this era. Earlier hulls typically incorporated a pilot berth to starboard alongside the main settee; by the mid-1980s Tartan eliminated the pilot berth in favor of shelving, which opened up the saloon somewhat and removed a chainplate complication in the process. Both versions appear on the used market, and the later arrangement is generally considered the more livable. The galley is to starboard at the base of the companionway, and the dedicated chart table sits opposite to port. Overall the layout reflects a genuine offshore mindset: sea berths are real, storage is generous, and the nav station is properly positioned.
Equipment and Common Upgrades
Boats that have passed through cruising-minded owners tend to arrive on the market reasonably well equipped. A chartplotter and autopilot are commonly fitted, as is a dodger — practically essential given the cockpit geometry — and a bimini that extends aft from the dodger to create a full weather enclosure. AIS transponders are widely carried, and radar appears frequently on more thoroughly equipped examples. Spinnaker inventories, both symmetrical and asymmetric, are a frequent addition among boats with any racing history or owners who appreciated downwind sailing.
Among upgrades that reflect deeper engagement with the boat, solar panels and inverters appear on a meaningful share of the market, sometimes paired with lithium battery upgrades where previous owners have committed to extended offshore or liveaboard use. Heating systems are a common retrofit among boats that have spent time in northern waters, and hot water heaters are nearly standard on boats that have been outfitted for extended cruising. Air conditioning appears occasionally on boats that have worked in warmer climates. The original alcohol stove is often replaced, with propane conversions being a frequent owner upgrade; the practical sailor should verify that any propane installation includes proper deck-level locker venting and a solenoid shutoff.
What to Inspect
The Tartan 37's reputation for solid construction is well-earned but should not be mistaken for immunity from the problems that accumulate in any production boat over several decades. The most consequential area to examine is the balsa-cored deck. The deck is prone to water intrusion and the resulting rot can be very expensive to repair, and it deserves thorough survey with a moisture meter across every square foot rather than spot checks at obvious deck hardware. Pay particular attention around chainplates, winch bases, stanchion bases, and any fitting that has been added or relocated by previous owners.
The hull-to-deck joint uses an aluminum backing plate glassed to the underside of the hull flange, bolted through to the deck and secured with the teak toerail. The combination of dissimilar metals creates potential for galvanic corrosion that can cause bolts to loosen or strip, and the toerail bedding is worth close examination since inadequate sealing allows water to pool in the joint. Lift the toerail sections at the bow to assess how well the bedding has held.
Deck hardware throughout the boat is backed with aluminum plates rather than individual washers, which again raises the question of corrosion from metal contact over time. Check for swelling or staining around any piece of deck hardware that passes through the cored deck. The cockpit scuppers are positioned such that they would be submerged while the boat is heeled and underway, yet they lack shutoff provisions — something to address if offshore passages are planned. Similarly, the bridgedeck is lower than is ideal for offshore work, and the plywood dropboards represent a vulnerability that many owners have addressed with custom companionway upgrades.
On the mechanical side, the original Universal or Westerbeke diesel is a robust but elderly unit on early hulls, and engine hours tend to be low on these boats given how well they sail — but a low-hours old diesel still warrants scrutiny for rubber components, heat exchanger condition, and raw water impeller maintenance history. The centerboard pennant routing through the center of the mast step adds complexity to the system, and the condition of the pennant and its associated hardware deserves attention on keel-centerboard models. The centerboard configuration also necessitates careful inspection of the trunk and pivot mechanism, areas where deferred maintenance compounds over time.
Rigging on boats of this vintage ranges from recently replaced standing rigging on well-maintained examples to wire that is well past its prudent service life on neglected ones. Treat any rigging of unknown age as a replacement item in your budget.
Availability and Buyer's Takeaway
The Tartan 37 is widely available across the eastern seaboard of the United States, where the bulk of these boats were originally sold and sailed. Additional inventory appears in the Great Lakes region, and examples surface regularly in the Pacific Northwest and Australia. The combination of deep owner-community knowledge, a dedicated owners association, and strong residual demand means that finding a boat is generally not the challenge — finding a well-maintained one at a fair position in the market is the work.
Before making an offer, confirm the following:
- Full professional survey with moisture meter readings across the entire deck surface
- Hull-to-deck joint condition, including toerail bedding and bolt integrity
- Condition of all aluminum backing plates behind deck hardware
- Keel configuration confirmed (fin, Scheel, or centerboard) and centerboard mechanism inspected if applicable
- Rig age and inspection records; rigging replacement factored into budget if unknown
- Engine service history, impeller dates, and heat exchanger condition
- Companionway dropboard and bridgedeck arrangement assessed for offshore adequacy
- Standing water or pooling evidence in cockpit sump corners
- Propane or CNG installation reviewed for code compliance if stove has been converted
- Owners association resources consulted prior to survey for model-specific known issues
