Design and Construction
Ta Chiao built the Scorpio 72 in fiberglass with a solid hull and long full keel, giving the boat a ballast-to-displacement ratio of just over 49 percent on a 114,000-pound displacement. The 56,000 pounds of lead ballast sit low in a hull whose length-to-beam ratio of 3.66 and 17.75-foot beam describe a voluminous, directional hull form rather than a lithe racer. With a wetted surface near 936 square feet and an immersion rate of roughly 3,150 pounds per inch, the hull settles heavily under load — a trait consistent with her draft of 6.76 to 7.06 feet varying with burden. The capsize screening value of 1.46 places her firmly in the offshore-cruiser band, and her theoretical hull speed of 9.6 knots is typical for a displacement vessel of this waterline length.
Rig and Handling
The Scorpio 72 wears a ketch rig, and the 1991 rig reference notes sheet dimensions that hint at the scale of her ground tackle. Jib and genoa sheets run about 65 feet with 5/8-inch diameter; the mainsheet stretches to roughly 162 feet, and spinnaker sheets to about 143 feet, all at the same 16 mm specification. Those lengths confirm a large sail plan demanding serious winches and lead blocks, while the ketch configuration splits driving area for easier short-handed trim downwind. Her skeg-hung rudder and full keel give predictable tracking, though the immersion rate means she responds slowly to changes in trim compared with lighter craft.
Accommodations
The available facts classify the boat as a large sailboat with a 50.92-foot waterline and a beamy 17.75-foot hull. The volume implied by those numbers and the 69.35 comfort ratio suggests a roomy, stable platform suited to liveaboard cruising.
The Verdict
The Scorpio 72 stands as a Perry-designed, Ta Chiao-built offshore ketch with the stability numbers and construction simplicity that appeal to long-distance cruisers. Her full-keel, solid-fiberglass hull and heavy ballast give reassuring seakeeping margins, while the ketch rig moderates sail-handling loads. Buyers should recognize the trade-offs of a 114,000-pound displacement hull: modest theoretical top speed, high immersion, and the expense of maintaining large-dimension running rigging.
Pros
- Robert H. Perry design with documented offshore stability (capsize screening 1.46)
- Solid fiberglass hull and long full keel built by Ta Chiao
- Ketch rig splits sail area for manageable handling
Cons
- Heavy displacement limits speed and responsiveness
- Large sheet lengths imply significant rigging wear and replacement cost
- Interior specifics not described in available facts
