1976 Bluewater Boats Ingrid 38

Seller's Description

Compassion is looking for a new master. She’s ‘jones-ing’ to get back in the water and under sail as we have aged-out in our abilities to liveaboard. The Ingrid 38 is a heavy displacement blue water ketch derived from Colin Archer’s famous double ender designs, inspired by Viking boats renowned for their heavy weather characteristics. “The kind of boat that behaves herself in rough water and can be depended upon to sail herself”… the superb one-finger-on-tiller tracking and a comfortable ride. With her old world style she’s a good looking boat with a sheer line. Her seaworthiness is there to see in her full keel, heavy displacement and overbuilt construction. Her hull is heavily hand laid in fiberglass, there’s robust outboard chainplates and an outboard rudder protected by extra fiberglass and a large bronze shoe casting should she scrub the bottom. Compassion is a traditional sailboat with a tiller and hank-on headsails, cutter and for’sail with 900 sf of sail.

Atkin’s main rework on the Ingrid 38 from Archer’s original design was a finer entry on the bow which ‘cushions’ her landing off the waves. Below the waterline she has a long full keel with deep v-sections forward keeping her stable in the rough. The ballast is encapsulated and is distributed from bow to stern, this helps her to avoid the pitching motion familiar to fin-keel sailors. Rounding this off, there’s plenty of flotation fore and aft which helps keep her dry.(Blue Water Boats)

The tradeoff heavy displacement and ultimate stability is usually in speed, the Ingrid 38 is not considered fast. Surprisingly she’s known to sail pretty well in light airs, owners reporting she’ll do half the wind speed up to 8 knots of wind. However, she’s a boat that comes into her own in heavier seas. By the numbers, her hull speed works out at 7.2 knots but she’ll more often manage a consistent 6 knots while cruising. The ketch rig gives plenty of options on all points of sail and she’s an easy boat to single-hand.(https://bluewaterboats.org/ingrid-38)

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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.
?
<16: under powered
16-20: good performance
>20: high performance
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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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: better suited for ocean passages
>2: better suited for coastal cruising
