Seller's Description

This highly customized Irwin 68 was completed in 1990 to a much higher construction specification than standard sister ship designs. Earl Blackwell, Jones & Associates, specialists in manufacturing process and design engineering, specified and blueprinted to a heavier hull and deck laminate that meet the National American Bureau of Shipping (ABS) standard. The result was an exceptionally strong Irwin that is well suited for offshore or island cruising.

she is in great shape with tons up upgrades and work done in the past 4 years. Safe, comfortable and fast. She has a master stateroom after with fulll head and bath tub, two full size staterooms just forward of the master each with full head. Main salon is huge with a wet bar, ice maker, big table that seats 8 comfortably. The galley is just forward and to starboard of the salon with two refrigerator freezer, 4 burner propane stove with oven, large sink, and lots of storage. Across from the galley is the utility room with tool storage, food storage and a newer washer dryer unit. Forward of is the crew area with tow bunks a large V birth and a shared head.

On deck she is large and safe. She has all the navigation equipment you need including newer Garmin gps with radar, new raymarine wind instrument independent depth sounder raymarine autopilot with new hydraulic pump in 18 and rebuilt hydraulic ram in 2019, 2 vhf radios one with AIS receiver. On the aft deck she has a large hot tub with new cover, large lazarett for storage, smoker/ bbq, 2 chest freezers, dinghy davit with solar mounted above. She has a custom built hard top designed and installed by Ted Irwin with 2 large solar panels on top.

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
