Rainbow Chaser is on land currently cradled on a Heavy Duty trailer with air bags and 5th wheel tongue. It is located just a few short miles from a nearby haul out yard for launch. The boat with or without the trailer is negotiable dependent on buyers wishes and ambitions. The Isuzu engine has been pulled and has been replaced with a running Perkins 4-108. Engine room needs stringers lowered to accommodate engine height.
The Union 36 is a heavy-displacement, full-keel, double-ended cutter-rigged cruising yacht (similar to Perrys U.S.-built Valiant 40).
Like others of its kind, the Union 36 has pleasing lines, and the boat often draws admiring glances.
As is the case with most Taiwanese-built boats from the 70s and 80s, the Union 36 is heavy with teak. The wood can be found in the interior joinery, the cockpit and coamings, cap rail and bulwarks, and decks, if they were specified during construction (as was the case with most Unions of that period). the Union 36 is usually excellent, showing craftsmanship that was affordable only because the local carpenters were paid a fraction of what their U.S. counterparts earned. The end result is a warm, inviting interior where brass lamps seem to belong naturally.
The interior of the Union 36 is straightforward, with plenty of headroom and ventilation. It is a good-sized boat with plenty of storage below, although the interior layout can vary slightly between vessels.includes a large double berth forward. Just aft on the port side is a head compartment with a separate stall shower, and across from the head is a large hanging locker.
The main saloon features a large U-shaped dinette to port (with plenty of storage behind and beneath the seats) and a long settee to starboard. The settee pulls out to form a sea berth or additional seating for the dinette. Theres also a full-sized pilot berth.The U-shaped galley is located to port and contains a deep double sink, a three-burner CNG stove/oven, and a 12-cubic-foot icebox

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 √LWLA 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)
