Seller's Description
The sturdy Mariner is a versatile boat for racing or a comfortable daysailer with four sleeping berths, potty locker, and self-bailing cockpit. For over forty-five years and 4,000 hulls, the rugged and practical construction of the Mariner has guaranteed high performance and low maintenance for solo sailors and families everywhere. With the board up, she drafts 10 inches and can be easily beached or sailed in shallows. She ghosts along in the lightest summer winds when other boats are standing still, but with the board down (draft 4’11”) she is stable when the wind picks up. With a spacious cockpit and comfortable seating arrangements, the Mariner provides an enjoyable sailing experience for small groups or families. Its quality design and construction ensure durability and performance on the water. Stuart Marine continues to manufacture new boats and supplies every part needed to repair or enhance your boat, from hardware to spars to rigging to cushions. Whether you plan to explore secluded coves or join in local regattas, the Mariner offers a perfect blend of speed, comfort, stability, and versatility.
Equipment: Boat comes with mooring eye, masthead light (line needs repair), outboard bracket, fire extinguisher, forward deck hatch, mainsail cover, swivel tongue jack, fresh a/f bottom painting & replacement weatherboard set, 6hp outboard and fuel tank, anchor with rode, full set of replacement standing rigging (unused), Windex vane (not installed), 4 piece cabin cushions, porta potty, life jackets, swim ladder, docking lines, fenders, spare tire and wheel on galvanized LoadRite trailer (recently serviced; new hubs installed), and life jackets.

Calculations
- Hull Speed

8.0 kn
Classic: 5.65 kn
Hull Speed
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Formula
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
- Sail Area/Displacement
-
23.2
>20: high performance
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
Formula
SA/D = SA ÷ (D ÷ 64)2/3
- SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D: Displacement in pounds.
- Ballast/Displacement
- ?
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Formula
Ballast / Displacement * 100
- Displacement/Length
-
114.2
100-200: light
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
Formula
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
- Comfort Ratio
-
9.1
<20: lightweight racing boat
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Formula
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
- D: Displacement of the boat in pounds
- LWL: Waterline length in feet
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
- Capsize Screening
-
2.5
>2.0: better suited for coastal cruising
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
Formula
CSV = Beam ÷ ³√(D / 64)
- Beam: Width of boat at the widest point in feet
- D: Displacement of the boat in pounds
Notes
The hull of the MARINER is the same as that of the RHODES 19. A fixed keel version was also available for both boats. In 1969, a ‘2+2’ version was introduced that has a slightly larger cuddy/cabin.
A modified version (with different cabin design) called the SPRINDRIFT ONE appeared in 1980 after the original molds were sold to Rebel Industries-(Spindrift One-Designs).(76 built).
Since 1986, the licensed builder has been Stuart Marine Corp. of Rockland, ME (USA).(Also builder of the RHODES 19).
