Seller's Description
Rhodes 19 Class # 318. Never upgraded for racing. Older boat ready to go. Remounted keel with SS bolts. Last in water in 2017. Ribs are good, rigging checked over, new jib halyard. Spinaker included but no rigging (Needs halyard, pole lift, sheets etc.) Genoa included with lead tracks on both sides. Outboard Motor mount, reconditioned rudder. Located on Martha’s Vineyard…check ferry rates at Steamshipauthority.com. Trailer is custom, not designed for launching, but could be used for that if willing to sacrifice it to rust. Has never been dipped and has very few miles. God for working on bottom, storage and shifting to launching travel lift. Needs new tires (4.80 x 8) for longer trip…$30 each, I’ll mount them for you. Trailer is registered as “Homebuilt” in Massachusetts…you could do the same. Boat has never be registered (Massachusetts does not require registration for boats without engines/motor. Keel was just sanded and primed and barrier coated. Bottom paint needs a good sanding and repainting for the 2024 season. Topsides are painted white, chipped here and there quite a bit. Deck is original Gel Coat Blue.
Equipment: Anchor needs 5’ of new chain. Swim ladder, All sails are old, usable for causal daysailing.

Calculations

8.8 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
-
27.6
>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
-
82.2
<100: Ultralight
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
-
6.5
<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
-
2.8
>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
Both the RHODES MARINER and the R-19 derived from the HURRICANE, built of molded plywood and sailed around the Chesapeake/LIS area (USA) during the late 1940s. A centerboard RHODES 19 is still available but only the fin keel version is permitted for class one-design racing.
