Seller's Description

The 1977 Mercator 30 is a classic sailboat that has several features and characteristics that may appeal to sailors and boaters looking for a reliable and practical cruising vessel.

Solid Construction: The Mercator 30 was built by the renowned Dutch shipbuilder, De Groot, and Sons, using high-quality materials and construction techniques. The hull is made of thick fiberglass, making it strong, durable, and resistant to impacts.

Comfortable Accommodations: The Mercator 30 features a spacious interior with a traditional layout that includes a main salon, galley, and head compartment. It can comfortably sleep up to six people, making it an excellent choice for family or friends.

Easy to Sail: The Mercator 30 has a simple and efficient sail plan, which makes it easy to sail for novice and experienced sailors alike. The boat is equipped with a hanked on jib and a main sail, which can be reefed for more manageable handling in high winds.

Classic Design: The Mercator 30 has a classic and timeless design, which appeals to many boaters who appreciate the traditional lines and aesthetics of older sailboats. It has a nostalgic charm and a distinct character that sets it apart from more modern vessels.

Overall, the Mercator 30 offers a combination of solid construction, comfortable accommodations, ease of handling, affordability, and classic design that make it an attractive choice for sailors and boaters looking for a reliable and practical cruising sailboat.

Tender included.

Calculations

Hull Speed
6.9 kn
Classic: 6.63 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

6.91 knots
Classic formula: 6.63 knots
Sail Area/Displacement
14.5
<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.
14.48
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
43.0
>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

42.99
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
303.3
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
303.28
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
32.3
30-40: moderate bluewater cruising 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
32.28
<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
1.6
<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
1.64
<2: better suited for ocean passages
>2: better suited for coastal cruising
