I am scaling down and want to see if anyone might be interested in completing the refitting process of an 1981 Mariner 39 Center Cockpit.
Sadly, I just don’ thave enough time to work on the boat anymore.
A large number of components have been replaced or serviced.
I will entertain any offers.
Equipment: It has a remanufactured Perkins 4-108 engine (less than 27 hour). I cleaned and relined the engine room with new sound insulation. All new exhaust system and hoses.
I replaced all of the portlights with bronze New Found Metal.
All of the hatches were removed, cleaned and powder coated. New lexan panels were put on them.
I installed new edson pedestal and got the compass serviced. Wheel was polished to look like new.
All new running rigging.
New chainplates and backing plates.
Soda blasted the bottom and put on 4 coats of west system barrier coat.
New traveler and block system.
New schaefer genoa tracks was installed.
I serviced all of the winches.
The windlass was sent off for rebuild by the manufacturer.
I removed the water tanks, stripped the inside coating and epoxy coat them and reinstalled the tanks.
All stanchions and their bases were removed and polished.Those that show wear were replaced with new custom fabricated pieces.
New teak hand rails were istalled on the cabin top.
Fuel tank was steam cleaned.
The teak panels around the portlights were replaced with epoxied plywood panel and off white laminate. Similarly, the headliner was removed and replaced with the laminate panels.
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)
Shoal draft version: 4.83’/1.47m
Originally the WESTSAIL 39 though few were built under that name. Hulls were laid up in San Pedro CA. USA and then delivered to Taiwan for finishing. Also referred to as FAIRWEATHER MARINER.
