Heartland is a very well kept Union 36 sailboat built in 1983 at the Union Yacht Co. in Taiwan. Originally designed by Robert Perry as the Hans Christian 34, He latter stretched the design and created the Hans Christian 36, Union Polaris, Mariner Polaris and the Union 36. Heartland has the pedigree of Bob Perry and Hans Christian along with the reality of a proven blue water cruiser. She also bears the pedigree of cruising off of Columbia, Venezuela and Panama along with the San Blas Islands by the previous owners.
Heartland was owned by friends of the current owner who brought her here to St Louis from Central America for a refit. The unfortunate death of one of the owners ultimately triggered the sale 5 years ago. The new owners were still working which gave them time to finish the refit and eventually transport her back to salt water in Fort Lauderdale. her refit was completed there and as life would have it she is available again. ready for cruising with many upgrades. Please see full specs, and additional info below.
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)
According to designer, Robert Perry, the HANS CHRISTIAN 36, MARINER POLARIS, UNION POLARIS 36, and EO 36 are all nearly the same, which, in turn, are lengthened versions of the HANS CHRISTIAN 34, the boat he was originally commissioned to design but, of which, few were built.
(previously listed here as UNION POLARIS 36).
