Seller's Description
2005 Rocket 22 #2205 with trailer, outboard and good sail inventory.
-A proven competitive sportboat plus excellent day sailor -PHRF 119, double-spreader carbon mast & carbon sprit, highly tuneable rig with adjustable mast screw-jack, squaretop main, and large assy spinnakers (rigged for companionway launch/retrieval but foredeck hatch can used as well) make for enjoyable sport boat racing. At the same time, a large cockpit, built-in cockpit cooler and functional cabin makes it very comfortable for recreational day sailing too. In sum, similar size, style and rating to a J70 but more comfortable.
-Easy to dry-sail: Retractable fin keel with new (2021) floorpad mounted stainless steel keel crane operated by deck winches (i.e. no need to load the mast or boom or for seperate winches to hoist or lower the keel).
Sails: -Over C$10k invested in recent sails: North 3Di Raw Jib (2020), North A1 reacher + A2 runner asymmetrical spinnakers (2019)
-Other sails include a North squaretop 3DL main (2013), a Dacron main, 2 older kevlar jibs, older asymmetric spinnaker, and a symmetrical spinnaker with carbon pole (never used).—
-New North jib sock (2021)
-Mast-mounted TackTick with thru-hull speed/depth transducer.
-Sleeps up to 4, rudimentary but far roomier down below than a J70 or M24 and handy for away regattas. Has full length interior cushions and v-berth (cushions not used, clean and dry stored for years)
-Includes transom-mounted Yamaha 4hp 4-stroke outboard.
-Complete with well-maintained RoadRunner trailer, travel mast supports, tie-down straps and recent spare tire.
-Has been dry-sailed (trailer moored) 5 of last 6 years and only ever sailed in fresh water. Hull polished, not painted.
-Full canvas winter cover for hull and deck.
Based in Alberta but gets raced in BC and Montana as well. Note, due to near-term travel separately provided delivery might be possible anywhere between BC and Toronto, or Canadian border points along the way.

Calculations
- Hull Speed

10.1 kn
Classic: 6.21 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
- Sail Area/Displacement
-
36.5
>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.
- Ballast/Displacement
-
37.5
<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
- Displacement/Length
-
72.0
<100: Ultralight
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
- Comfort Ratio
-
6.6
<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
- Capsize Screening
-
2.9
>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
Notes
A development of the earlier, Mull designed, POCKET ROCKET.
