1998 Endeavour Endeavourcat 36


Seller's Description

The EndeavourCat 36 is the perfect Bahamas, Carribean, South Florida and East Coast. This EndeavourCat 36 has been owned by the seller since 2007. Valkyrie has been exceptionally well maintained, constantly upgraded and kept to the highest standards. She has everything you need for extended cruising, and just had 3 coats of fresh ablative bottom paint in May, 2024.

With a draft of only 2’10 she can go almost anywhere. Her cruising spinnaker allows her to travel in light air, and with her heavy-duty full-battened Mainsail and Full-battened Camber-spar self-tacking Jib (both made for her by Mack Sails) she can also safely handle heavy weather, and anything in between. The two Volvo diesel engines were upgraded to the larger MD2030, 29hp motors and the saildrives were upgraded from SA-120s to brand new SA-130s with new bronze Volvo folding props in 2007, so she can get you wherever you want to go regardless of the weather or wind while still only burning 0.3 gallons/engine/hour. If it gets squally outside no worries your full length Nida-cored fiberglass walk-on hardtop won’t let a drop of rain touch the helm station. Just relax in your captain’s chair, turn on the windshield wipers and RADAR and sit back, warm and dry, until the squall subsides. The chartplotter-interfaced AIS receiver will also let you know if there’s dangerous traffic out there.

The 3.5 KW generator by NextGen and CruiseAir reverse-cycle ducted air conditioner will keep you cool and powered up once you get there and the 200 gallon/day watermaker will keep your tanks full so you can enjoy daily showers in the dedicated stand-up shower stall. Cook dinner on the propane stove or in the oven, or use the microwave, or maybe grill on the aft deck on the Magma BBQ. The ICOM M-710 SSB/HAM radio keeps you in touch offshore and the Pactor3 modem lets you get and send emails anywhere in the world for free. Queen sized beds with memory foam matresses make for comfortable sleeping.

All the major big-ticket jobs habe been done as needed. Saildrive bellows replaced in 2021,bottom paint2024,etc

Hull Speed
10.9 kn
Classic: 7.7 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

10.85 knots
Classic formula: 7.7 knots
Sail Area/Displacement
16-20: good 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

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
100-200: light

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


Similar to the EndeavourCat 34 with the addition of a 4’ wide sidewalk across the stern.
Standard twin 29 hp diesel engines.
