Westerly Sealord 39 Ketch Ketch 1983 vs Westerly Sealord 39 Sloop Sloop 1983 — Same Brand, Different Boat

The Westerly Sealord 39 Ketch Ketch 1983 vs Westerly Sealord 39 Sloop Sloop 1983 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Westerly Sealord 39 Ketch Ketch 1983 at 38,6 ft versus Westerly Sealord 39 Sloop Sloop 1983 at 38,6 ft. At 18 501 lbs and 18 501 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Both boats sit in a similar displacement bracket — 18 501 lbs for the Westerly Sealord 39 Ketch Ketch 1983 and 18 501 lbs for the Westerly Sealord 39 Sloop Sloop 1983. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth — 5,6 ft and 5,6 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

Sailboat comparisons often come down to details that specs don't fully capture — the quality of the standing rigging, the layout of the cockpit, and how the boat feels on a beat in 20 knots. A sea trial on both is strongly recommended.

Hull speed is rated at 7,6 knots for the Westerly Sealord 39 Sloop Sloop 1983 and 7,6 knots for the Westerly Sealord 39 Ketch Ketch 1983.

Bottom line: The Westerly Sealord 39 Ketch Ketch 1983 and Westerly Sealord 39 Sloop Sloop 1983 are closely matched on paper. A sea trial on both in representative conditions is the only reliable way to find which one suits your sailing style, home port, and intended cruising ground.

Which is the larger boat — the Westerly Sealord 39 Ketch Ketch 1983 or the Westerly Sealord 39 Sloop Sloop 1983?
The Westerly Sealord 39 Sloop Sloop 1983 is the longer of the two at 38,6 feet overall. The Westerly Sealord 39 Ketch Ketch 1983 comes in at 38,6 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Westerly Sealord 39 Ketch Ketch 1983 or the Westerly Sealord 39 Sloop Sloop 1983?
For trailering, the Westerly Sealord 39 Sloop Sloop 1983 has the edge at 18 501 lbs dry weight versus 18 501 lbs for the Westerly Sealord 39 Ketch Ketch 1983. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Westerly Sealord 39 Ketch Ketch 1983 is Coast Guard rated for 11 passengers, while the Westerly Sealord 39 Sloop Sloop 1983 is certified for 11.

Which boat has the deeper draft — the Westerly Sealord 39 Ketch Ketch 1983 or the Westerly Sealord 39 Sloop Sloop 1983?
The Westerly Sealord 39 Sloop Sloop 1983 has the deeper draft at 5,6 ft, versus 5,6 ft for the Westerly Sealord 39 Ketch Ketch 1983. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Westerly Sealord 39 Ketch Ketch 1983 or the Westerly Sealord 39 Sloop Sloop 1983 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators.

Keep in mind that actual sailing speed depends heavily on wind conditions, sail trim, bottom condition, and skipper experience — hull speed is a theoretical maximum, not a guarantee.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Westerly Sealord 39 Ketch Ketch 1983 and Westerly Sealord 39 Sloop Sloop 1983 share an 13.20 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads.
