Very nice and successfully raced Santa Cruz 27 for sale. GOTCHA has been upgraded and loved for over 22 years now. The boat is ready to race in the Nationals (twice previous champion) or one design series and is extremely competitive in SF Bay PHRF competitions with a PHRF rating of 141. Boat is fast in all conditions and points very well.
Some Details:
1975 vintage, hull #27
Keel box and deck were rebuilt. New bottom gelcoat, all in 2011.
Bottom has been redone and long boarded; keel and rudder faired.
Stock rudder was replaced in 2005 with a class rudder.
Gelcoat bottom is sanded with 600 grit and in excellent condition. Stored on trailer.
Original winches have been replaced.
Running rigging is in very good condition. Standing rigging was replaced in 2012.
Deck hardware has been replaced and repositioned to make the sailing controls simple.
The toe rail has been removed and much of the deck recored, hence a very stiff boat.
Newer non-skid is on the deck.
Sails:
Quantum class mainsail , flattening reef – Excellent (new)
.6 oz Ullman Airex spinnaker – Very good (2013)
Ullman main – good (2013)
.75 oz Santa Cruz spinnaker – average
North main, one reef point – average
Spinnaker pole was replaced in 2016.
Honda 2.3 outboard, 2016, 4-stroke.
Road worthy dual axle trailer. Ramp launch capable.
More Details:
Trailer serviced and repainted in 2016.
Hull and mast repainted in 2017.
Rebuilt the cockpit seats and floor in 2018.
Rebuilt manual bilge pump – 2020
New self-tacking traveler car – 2020
New #3 jib in-haulers – 2020
New lower backstay – 2020
New port/starboard vang controls – 2020
Mast-mounted TacTic: speed, course, depth, timer, countdown.
Hand-held VHF radio.
November 2020
Newly installed battery, stock running lights, tri-color masthead light, masthead VHF antenna, steaming light, cabin light, lit bulkhead compass, VHF radio, batt. on/off switch, electrical panel, housing for radio and electrical panel and all associated wiring.

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)
