1999 Custom Handmade Wittholz Cat Boat

Listed
Expired
$29,950 USD

Seller's Description

Not a mass produced, fiberglass boat. Hand-made, took 7 years to craft. Unmatched character and detail. Wood structure and hull, cold-molded with West System Epoxy. Every piece built from premium materials with exactness you cant find in a production boat. Hand made blocks, hand made mast, boom, interior, teak seats, centerboard, rudder and hull/deck structure, hand-cast bronze, bright-work and lead ballast. Brand new cushions (never sat on) covered in Hunter green Sunbrella. Brand new Honda commercial 13 HP, 389cc electric start, gas in-board engine. The gearbox is original and very heavily built, fully serviced and will last a lifetime. Bronze 2-blade propeller. New fuel fittings, engine wire harness, cooling relays, freshwater pump for exhaust cooling system. 12v engine cooling fan. Engine bay exhaust fan. Manual bilge pump. This Winter the boat was refinished with new bottom, hull, cockpit, top-side paint, rub rail and cockpit/cabin floor non-skid. Mahogany doors, trunk-top, fold-away table, vents and trim have multiple coats of Epiphanes clear and are standing tall. No need to re-finish the mahogany or anything on the interior. The boat and components function and look as brand new. The Gaff sail is Tanbark and was custom made by Quantum. The cabin and cockpit have tons of storage compartments. Built-in cooler, a new (unused) butane cooktop, a wall mounted compass, brass clock and barometer, brass 12v ceiling light, brass oil lamp on gimball and all the equipment needed to go directly onto the water. Galvanized trailer w/dual axles and mechanical brakes. Rollers are covered with canvas to keep from marking the hull, tires are new, lights function perfectly and it tows very well. The boat but it is truly a one-of-a-kind Charles Wittholz Cape Cod design. I have the original blueprints from Charles’ Wife that were used for the build. Not a penny was spared in the build or maintenance and its a boat that can be handed down through generations. An injury forces sale.The title is clear. Tons of pics available. Call or email.

Equipment: Too much to list. Please call or email and I’ll provide everything needed. Ready to sail in every respect. I don’t have pictures of the newly painted boat in the water as it hasn’t been in the water since the work. I can get additional “new” pics but injury limits ability to move the boat, set the sail. You will not be disappointed!

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
