Seller's Description

Rare opportunity to own a Nimble!

  1. Sloop rigged.

Built by Gerry Koch who founded Nimble Boat Works, 1985, in Clearwater FL. All Nimbles were custom built.

This Nimble 30 is one of only 29 built between 1985-97. Designed by world renowned yacht designer, Ted Brewer. (Ted also owned a Nimble30).

My Nimble 30 is a solidly built blue water boat. 29.92 LOA 9.4 beam. Draft max:4.50. Fuel diesel 18 gal. Water 52 gal. 6 gal holding tank. Wet head.

6ft plus headroom. Fab wide opening skylight over salon.

Centerboard retractable keel. 2’5”up, 5’4” down. Keel mast.

2GM Yammer engine.

All bronze portholes and winches. Screens for portholes.

Lots of storage! Under V berth, in V berth, small V berth closet. Storage in salon and under salon benches. Salon table(small storage here as well) over centerboard keel. Some storage in head. Great amount of storage in cockpit.

New sails and jib.

Negotiable: wood stove. Cubic Grizzley with glass door. Not on boat currently. Extra.

Calculations

Hull Speed
8.4 kn
Classic: 6.79 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

8.44 knots
Classic formula: 6.79 knots
Sail Area/Displacement
20.7
>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.
20.68
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
37.7
<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

37.69
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
171.8
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
171.81
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
19.0
<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
18.95
<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
2.0
>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
2.0
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

A keel/cb version was also offered.
Draft: BU: 2.5’/ BD: 5.5’.
Available as sloop or yawl.
