Oyster Yachts HP46 Sloop Sloop 1981 vs Oyster Yachts Lightwave 48 1987 — Same Brand, Different Boat

The Oyster Yachts HP46 Sloop Sloop 1981 vs Oyster Yachts Lightwave 48 1987 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 — Oyster Yachts HP46 Sloop Sloop 1981 at 45,1 ft versus Oyster Yachts Lightwave 48 1987 at 48,1 ft.

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

For family outings this is probably the sharpest distinction between the two. The Oyster Yachts Lightwave 48 1987 is rated for 14 passengers, while the Oyster Yachts HP46 Sloop Sloop 1981 caps at 13.

That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Both boats draw a similar depth — 6,7 ft and 6,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Oyster Yachts HP46 Sloop Sloop 1981 uses Sloop rigging.

For extended cruising, water capacity matters: the Oyster Yachts HP46 Sloop Sloop 1981 carries 145 gallons versus 127 gallons on the Oyster Yachts Lightwave 48 1987 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Oyster Yachts HP46 Sloop Sloop 1981 is the offshore and bluewater choice — at 31 967 lbs displacement and 45 ft it has the load capacity, range, and seakeeping for extended passages. The Oyster Yachts Lightwave 48 1987 at 27 007 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
