Seller's Description

OFFLINE” is an Island Packet 320, the Cruising World Magazines’ 1998 Best Midsize Cruiser “Boat of the Year”, an exceptional cruising yacht, built by the famed yacht designer Robert Bob Johnson. Her classic design has been turning heads in harbors for decades. Since her millennium debut as the Dock Queen at the 2000 Annapolis Boat Show as the Showboat she is still only 25 years young. She withholds the craftsmanship and value that only Island Packet Yachts can achieve. Island Packet Yachts have a vast supportive community following in addition to the continued access to customer support from a company that still makes yachts! She is in amazing condition considering her age. Sporting a colorful pedigree, OFFLINE is only a three-owner boat, notably the first owner devotedly for 20 years. Her graceful lines, proper teak brightwork and luxurious trim level set her apart from others. She has been professionally maintained and tended to throughout the years. Her full keel, protected screw/rudder, and twin backstays enhance the versatility of her cutter rig and sail plan. Only (54) hulls were completed, OFFLINE, is a rarity when it comes to Island Packets. She has cruised the East Coast and been stored protected on the hard during winter for her first 21 years. For the last two and a half years she has been lived aboard and sailed conservatively. The current owners have 16 years of liveaboard experience. Her current captain is a professional mariner and a personal sailor with a lifetime of nautical experience from previously owning three yachts. Make certain OFFLINE has been mindfully preserved and painstakingly protected with a careful eye for safety and her future crew. Moreover, the owner maintains detailed records, receipts, logs, and manuals that date back 25 years. She is a USCG documented vessel, (26$ Annual renewal fee). Records are available to be provided to Serious Buyers. No hidden secrets, just ask your questions after you have reviewed the detailed listing data and photos. (Listing is available upon request)

Equipment: The detailed listing PDF is over 14 pages long and will not fit in this text block. Again, please reach out through email for the full listing and additional photos. I look forward to sharing the logbook of “OFFLINE”. Your log entry is next…

Calculations

Hull Speed
7.2 kn
Classic: 6.96 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

7.24 knots
Classic formula: 6.96 knots
Sail Area/Displacement
15.7
<16: under powered

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.
15.69
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
44.5
>40: stiffer, more 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

44.46
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
306.1
300-400: heavy

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
306.12
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
27.0
20-30: coastal cruiser

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
26.96
<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 ocean passages

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
1.97
<2: better suited for ocean passages
>2: better suited for coastal cruising
