The Cheoy Lee Offshore 40 1970 vs Cheoy Lee Sportfish 1988 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.
Size is the most obvious dividing line here. The Cheoy Lee Sportfish 1988 measures 70,0 feet overall (1988), giving it roughly 30,0 additional feet of deck space compared to the Cheoy Lee Offshore 40 1970 at 40,0 feet (1970). Weight tells a clearer story for trailering families: the Cheoy Lee Sportfish 1988 tips the scales at 96 000 lbs — 76 000 lbs less than the Cheoy Lee Offshore 40 1970 at 20 000 lbs. 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.
The Cheoy Lee Sportfish 1988 tops out at 1 050 hp. Engine specs for the Cheoy Lee Offshore 40 1970 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 3 gal and 2 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Cheoy Lee Sportfish 1988 is rated for 21 passengers, while the Cheoy Lee Offshore 40 1970 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cheoy Lee Sportfish 1988 could be the deciding factor.

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 — 6,0 ft and 6,0 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Cheoy Lee Sportfish 1988 has a documented auxiliary engine of 1 050 hp.
For extended cruising, water capacity matters: the Cheoy Lee Offshore 40 1970 carries 85 gallons versus 6 gallons on the Cheoy Lee Sportfish 1988 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Cheoy Lee Sportfish 1988 is the offshore and bluewater choice — at 96 000 lbs displacement and 70 ft it has the load capacity, range, and seakeeping for extended passages. The Cheoy Lee Offshore 40 1970 at 20 000 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
