2021 eXploder Scorpion (wide-beam)

Listed

Seller's Description

2021 eXploder Scorpion, wide beamed version (latest generation). Minimum-weight and fully up to-date, turnkey with a complete measurement certificate. Available for immediate delivery on the U.S East Coast (price negotiable). Trailer not included, but negotiable. Fast boat with a 10th place overall finish at the 2021 Worlds and numerous top 10 finishes in U.S racing.Full Spec’s: 1) Platform first launched in June 2021, ~40 days of use. 2) Complete 1D sail set, new in September of 2021; ~40 days on the main, 15 days on the jib and 15 light air days on the polyester spinnaker. All sails are white. 3) Complete Robline rigging fit-out, updated over time (new spinnaker halyard/single-line tackline system September 2023, new downhaul September 2023 etc.) 4) 12:1 Ronstan/Frederickson Mainsheet 5) Better than factory new fitout; all hardware was replaced with 316 stainless steel (from factory 18-8 stainless) and the aluminum isolated. Trampoline tie-points replaced with stainless steel spacers instead of plastic (no chafe on the trampoline lacing). Lower daggerboard bearing inserts re-glassed into hull (full tabbed) and bearings re-built to include rubber bumpers (protect daggerboard trailing edge). All work completed in the spring of 2023. Boat has since sailed the NE100 and 2023 North American’s with zero issue. 5) Full yard cover, hull covers, beach wheels, hull chocks (all 2021), rigging bag, beam bags.Optional extra’s: A) Landy jib, used 15 days B) Brand new spare daggerboards, brand new complete spare rudder system. C) Spare spinnaker pole (new, internal 2:1 tackline). D) Spare spinnaker hoop and bag E) Like-new turnbuckle standing rigging (used 5 days in freshwater).

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
