Babylon - 1987 Catalina 36
WING KEEL - TALL RIG
Many upgrades to both seaworthiness and cabin comfort over my past four years of ownership totaling over $17k (actually tracked and not counting regular maintenance and repairs), including 16k btu reverse cycle heat/AC (2020), new refrigeration (2023), solar arch (2021), spinnaker (2020), many electrical improvements, LPG conversion, potable water, and other systems.
Many more pictures available upon request via google photos link. Copy of 2017 professional survey available upon request.
PA title and registration. Berthed in a lovely marina in Old City in the downtown area of Philadelphia, with a potentially transferable slip.
Layout At the base of the companionway steps is the U shape galley to port, featuring a newer Dickinson stove/oven, a fridge with brand new compressor/evaporator, ample storage space, and a double basin SS sink with filtered water. Opposite the galley on starboard is a large chart table and seat, along with the electrical panel. The salon features a large U shape seating area and table to port, which converts to a full double berth. On starboard is a two-seat dinette, which also converts to a single settee. On the bulkhead is mounted a 42 4k 60hz TV. Going forward is a very large head with a thermostatic shower and sump. Large lockers and drawers throughout. Finally, aft is the guest stateroom with another double berth, settee, and hanging locker.

Electrical System and Solar -2x FLA Group 27 100amp hr House Batteries (2020) -1 FLA Group 27 100amp hr Starter Battery (2020) -300 amp hours total -Complete DC rewire, replacing undersized non-tinned factory cables with correctly sized tinned Ancor cables with heat shrink protected terminals. In normal configuration, all loads and charging sources are connected to house bank, house bank charges starter battery via battery to battery charger, and starter battery is connected to starter motor. -High amp switches allow isolating either the house bank or the starter battery, and doing everything from the remaining system. Also allows paralleling house bank and starter battery for engine start if needed for some reason. (2021) -Blue Sea SI-ACR Automatic Charging Relay (2021) -Blue Sea SafetyHub 150 installed to handle DC additions (solar, etc) (2021) -Appropriate battery fusing added where none existed previously (2021) -Balmar SG200 battery monitor (2021) -Balmar Bluetooth dongle (2021) -Statpower True-Charge 20amp Multistage Battery Charger -Secondary 30 amp service installed with Smart Plug receptacle/cable, BlueSea distribution panel. This runs reverse cycle heat/AC, or high amp electric heaters for winter (2019) -Yandina GI-50N Galvanic Isolator (2021) -2x 30amp Shore Power Cords: 1 Smartplug (at boat end), 1 standard -2x secondhand 100w solar panels installed (2021), 200w total. The solar arch, wiring (8awg), and Victron controllers are all sized to support 2x 200W or larger panels -2x Victron MPPT 75/10 solar controllers (2021)
… ran out of room for equipment list. Please message me, I have much more to share
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
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
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
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
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)
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)
