RM Yachts RM 1180 Twin keel Twin keel 2015 vs RM Yachts RM 800 1992 — Same Brand, Different Boat

The RM Yachts RM 1180 Twin keel Twin keel 2015 vs RM Yachts RM 800 1992 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 RM Yachts RM 1180 Twin keel Twin keel 2015 measures 42,1 feet overall (2015), giving it roughly 15,6 additional feet of deck space compared to the RM Yachts RM 800 1992 at 26,5 feet (1992). Weight tells a clearer story for trailering families: the RM Yachts RM 1180 Twin keel Twin keel 2015 tips the scales at 15 432 lbs — 9 987 lbs more than the RM Yachts RM 800 1992 at 5 445 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 power gap is worth calling out. Rated to 50 hp, the RM Yachts RM 1180 Twin keel Twin keel 2015 has a 40-hp advantage over the RM Yachts RM 800 1992's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The RM Yachts RM 1180 Twin keel Twin keel 2015 is rated for 12 passengers, while the RM Yachts RM 800 1992 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the RM Yachts RM 1180 Twin keel Twin keel 2015 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The RM Yachts RM 1180 Twin keel Twin keel 2015 displaces 15 432 lbs — a 9 987-lb difference over the RM Yachts RM 800 1992 at 5 445 lbs. 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.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The RM Yachts RM 1180 Twin keel Twin keel 2015 draws 6,5 ft, compared to 3,1 ft for the RM Yachts RM 800 1992. That 3,4-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

The RM Yachts RM 1180 Twin keel Twin keel 2015 is rigged as a Sloop while the RM Yachts RM 800 1992 carries cutter rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the RM Yachts RM 1180 Twin keel Twin keel 2015 uses a 2 wheels versus a 1 tiller on the RM Yachts RM 800 1992. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the RM Yachts RM 1180 Twin keel Twin keel 2015 carries a 50-hp engine against 10 hp on the RM Yachts RM 800 1992. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the RM Yachts RM 1180 Twin keel Twin keel 2015 carries 79 gallons versus 53 gallons on the RM Yachts RM 800 1992 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The RM Yachts RM 1180 Twin keel Twin keel 2015 is the offshore and bluewater choice — at 15 432 lbs displacement and 42 ft it has the load capacity, range, and seakeeping for extended passages. The RM Yachts RM 800 1992 at 5 445 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
