Seller's Description

1995 Menger 19 Cat With Trailer

Selling a Menger 19 catbaot with trailer. The Menger Cat comes with a newer sail (only used about a dozen times) and also has a nice 9.9 Honda four stroke outboard. The Menger is very spacious and is the perfect pocket cruiser. The cabin has sitting headroom for a 6’ 8” person, and the bunks measure 10 feet so there is ample room for you to sleep. The cockpit is large enough for eight people to sit comfortably.

With all lines leading back to the cockpit, the boat is easily single-handed. Her shallow draft allows access to many anchorages unavailable to other cruisers. With a trailer and a tabernacle folding mast (easily raised by one person), your cruising range is unlimited. Comes with a custom trailer with rollers.

The boat has been stored since 2013 and could use a good cleaning and may need new interior cushions. $12,500.

Equipment: Standard Features line reefing for lower reef. Fiberglass: All hand-layed up, Isophthalic gelcoat, five layers of mat and woven roving in hull and deck. White hull, tan deck with white cabin sides, deck non-skid molded in. Molded cockpit with two lockable hatches. Deck fiberglass to the hull all around. Molded headliner, hull liner and bunks. Centerboard and rudder solid fiberglass. Laminated ash and mahogany tiller. Teak: All exterior trim is solid teak; rubrails, handrails, brow on cabin sides, cockpit coaming caps, hatch trim, teak ply framed with solid teak drop board. Teak boom crutch with brackets on each side of tiller. Bronze: All hardware is bronze including, four mooring cleats, two halyard cleats, topping lift cleat, reefing line cleat, two chocks, five fixed ports, traveler, hatch hinges, hasps, forestay tang and triple gudgeons and pintle Spars: All spars painted with polyurethane, buff color. Tapered aluminum mast with top painted white, gaff and boom slotted extrusion. Gaff saddle molded fiberglass. Rigging: Stainless steel forestay with bronze turnbuckle. Three strand spun Dacron halyards, topping lit and mainsheet. Mainsheet jam cleat. Halyards, topping lift and single line reefing lines to cockpit. Lazy jacks, adjustable fore and aft on boom. Harkin ball bearing blocks.

Hull Speed

Classic: 5.76 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.


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

6.79 knots
Classic formula: 5.76 knots
Sail Area/Displacement
>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.


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
<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.


Ballast / Displacement * 100

<40: less stiff, less powerful
>40: stiffer, more powerful
200-275: moderate

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.


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
<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.


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
>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.


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


Inboard Diesel engine available as an option.
A later version was called the THOM CAT 19.
