1996–2003 · designed by Tim Jackett (Tartan Yachts design office) · built by Tartan Yachts (revival entity)
Modern 41 ft offshore cruiser-racer from the revival-era Tartan Yachts under designer Tim Jackett. Mid-size premium production hull positioned above the Tartan 372 in the revival range. Modern hull form, modern cored-deck construction, spade-rudder steering. Designed for serious coastal cruising with offshore capability — popular with US East Coast + Great Lakes owners wanting a step up from the 37-foot size class.
Check this first — three keels were offered — a deep fin, a beavertail moderate-draft, and a shoal centreboard — so draft and displacement both depend on an option the model name does not carry. The centreboard version additionally brings a board, pennant and trunk to inspect that the two fixed keels do not have. Establish which of the three before pricing or comparing.
This is a general read on the Tartan 4100 class — informed background, not a verdict on any individual boat. Condition, refit history, and how a particular hull was sailed and stored matter far more than class reputation. Use it to know what to look for; for a read on a specific listing, run a free FairKeel report on that boat.
Revival-era Tartans used balsa- or foam-cored decks. At 20+ years check moisture at all deck hardware penetrations, chainplate routes, and stanchion bases. NOT the chainplate-corrosion concern of the classic Tartan 37 — modern chainplate routing is different — but core moisture is the comparable inspection priority for this generation.
Spade rudder = less hardware protection than a skeg-hung design. Rudder bearings typically due at 15-20 years for offshore-prep work. Check for play in the rudder stock, water intrusion at the stuffing box, and corrosion at the rudder-post weldments inside the hull.
Keel-stepped mast. Original wire + tangs typically due at 20-25 years; hulls from 1995-2003 are at or past the re-rig window. Confirm date of most-recent re-rig.
Original Yanmar 4JH-series diesels from this era are reliable and well-supported in the US market. Service-history documentation and recent oil-analysis results are load-bearing — modern Yanmars run a long time with maintenance.
This guide is the class. A report is that hull. Paste the listing you're looking at and FairKeel grades every claim in it against what's known about the Tartan 4100 — where the evidence is thin, the red flags worth a second look, the costs likely to land in your first season, and whether the boat suits the plans you describe in a few short questions.
It won't read the photos or put a number on the boat — that's the $249 Deep-Dive, and for the real answer, a surveyor. It will tell you when a Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
