Seller's Description

This classic beaty has been refit over the last three years and is ready to sail. The refit included new gelcoat on white hull, new ribs, new standing and running rigging, fresh bottom paint, new keel cable and pivot bolt, new jib, new battery, new auto-bilge pump, new swim ladder, new custom removeable cockpit table, new fenders, new tiller tamer. The wood floor and cockpit trim brightwork are redone. Includes two full length docking lines, jib downhaul, and topping lift, mainsail cover, cockpit tonneau cover, two anchors, and boom tent. The motor is a 55 lb. thrust trolling motor which will push the boat against the Humboldt Bay tide. The trailer has new tires and wheel bearings, new wiring and LED lights, new jack, new hitch and new wench cable. She’s a joy to sail, as their reputation maintains.

Calculations

Hull Speed
8.2 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

8.17 knots
Classic formula: 5.65 knots
Sail Area/Displacement
23.3
>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.
23.34
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
32.3
<40: less stiff, less powerful

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

32.28
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
105.8
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
105.78
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
8.4
<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
8.4
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
2.6
>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
2.55
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

The RHODES 19 has it’s origins with HURRICANE class (1945) which was a molded plywood centerboarder with an open cockpit built by Allied Aviation Corp. Another builder, Palmer Scott, purchased a number of unfinished HURRICANE hulls, added a foredeck with cuddy cabin, and a fixed keel. This boat was sold as the SMYRNA. It was from the SMYRNA that Marscot Plastics made a plug for a fiberglass version. This was the boat that was later sold by O’Day Corp. as the RHODES 19.
There are keel and centerboard versions. The fixed keel version become the standard for class racing.
