Detailed Evaluation & Buyer Recommendation

RM Yachts RM 1270 Twin keel Twin keel 2015 vs RM Yachts RM 1370 Swing keel Swing keel 2017 — Same Brand, Different Boat

The RM Yachts RM 1270 Twin keel Twin keel 2015 vs RM Yachts RM 1370 Swing keel Swing keel 2017 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.

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 RM Yachts RM 1270 Twin keel Twin keel 2015 carries a rated maximum of 55 hp. Engine data for the RM Yachts RM 1370 Swing keel Swing keel 2017 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the RM Yachts RM 1370 Swing keel Swing keel 2017 carries 93 gallons versus 40 gallons in the RM Yachts RM 1270 Twin keel Twin keel 2015. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The RM Yachts RM 1370 Swing keel Swing keel 2017 displaces 29 183 lbs — a 7 137-lb difference over the RM Yachts RM 1270 Twin keel Twin keel 2015 at 22 046 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.

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

The RM Yachts RM 1270 Twin keel Twin keel 2015 uses cutter rigging. The RM Yachts RM 1270 Twin keel Twin keel 2015 has a documented auxiliary engine of 55 hp.

Hull speed is rated at 8,8 knots for the RM Yachts RM 1370 Swing keel Swing keel 2017 and 8,4 knots for the RM Yachts RM 1270 Twin keel Twin keel 2015. For extended cruising, water capacity matters: the RM Yachts RM 1370 Swing keel Swing keel 2017 carries 159 gallons versus 127 gallons on the RM Yachts RM 1270 Twin keel Twin keel 2015 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The RM Yachts RM 1370 Swing keel Swing keel 2017 is the offshore and bluewater choice — at 29 183 lbs displacement and 49 ft it has the load capacity, range, and seakeeping for extended passages. The RM Yachts RM 1270 Twin keel Twin keel 2015 at 22 046 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
