Seller's Description

Herreshoff America 18, 1976 sailboat for sale Madison Alabama

Selling the ‘Ooh La La’ after five years of restorations and sailing. I hesitated putting her up for sale but I need a bigger boat that can go offshore.

Here’s what she has:

Brand new still in the bag sail from Precision Sails complete with Stars and Stripes printed just like the original sail-see the last pic showing the design specs I sent to the sailmaker. Sail is made of Bainbridge sailcloth and comes with all the battens and two reef lines. Cost was $2,100. tabernacle mast mount two new deep cycle batteries in 2022 new flexible Sunpower 50W solar panel with new Renogy inverter/charging station -B&W radio with 8’ high-gain Shakespear antenna -Lowrance dual GPS and depth finder. Depth sensor is mounted to the hull -automatic bilge pump -Shore power hookup -Simrad Tiller Pilot TP10 -reupholstered cabin cushions in excellent condition -4HP Nissan 4-stroke in the engine well with custom forced air feed to overcome the chronic collecting of exhaust gases in the well that these boats are known for. Works great. Includes new spare propeller and plug. custom bronze running lights off an antique ChrisCraft -mast light -bottom paint done in 2020 (it’ll probably need to be redone at the end of the season if you leave her in a slip) -Teak refinished in 2020. The sun was pretty hard on it in 2021 and 2022 and could use touching up (see photos for some examples) -Original all-bronze hardware -Sheets and halyards in very good condition. Most are new either in 2020 or 2021 -No soft spots anywhere on the deck or hull -Lazy Jacks -Includes the original sail (the one pictured). You might be able to revitalize it if you have some sail making skills -Sail cover (it is home made and works great but I don’t have sail making skills!)

Trailer in great shape. Dual axle. Front axle has electric brakes. It has taken the Ooh La La as far north as Tim’s Ford Lake and as far south as Sarasota bay. Tires are new and it comes with a spare.

The one thing that isn’t true to the original boat is the seating in the cockpit. There was none when I bought it. The benches are made out of oak. The gaff jaws need replacing (see pic). I’ll knock some off the price if I don’t get that done before she’s sold. Some of the teak can use some refinishing. Same for the oak benches. It’s only cosmetic though- no structural problems what so ever. I took some close-ups to show some examples or phone (256)850-four-one-four-five

Calculations

Hull Speed
6.7 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

6.7 knots
Classic formula: 5.65 knots
Sail Area/Displacement
22.6
>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.
22.58
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
20.0
<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

20.02
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
199.6
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
199.6
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
13.4
<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
13.44
<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
2.4
>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
2.36
<2: better suited for ocean passages
>2: better suited for coastal cruising
