Pearson 27 (Triton 27)

Pearson 27 (Triton 27) is a 27 ′ 0 ″ / 8.2 m monohull sailboat designed by Doug Peterson (unauthorized) and built by Pearson Yachts starting in 1986.

Rig and Sails

Auxilary power, accomodations, calculations.

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

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

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

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

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

Displacement / Length Ratio

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

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

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 Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

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)

This version of the PEARSON 27 is the same as the TRITON 27 and similar to the earlier US 27 by US Yachts. In 1984-85 Pearson sold a line of sailboats that it called the Tritons. The molds for these yachts were actually purchased from US Yachts, a division of Bayliner Inc. (the Buccaneer series of sailboats). Shoal draft: 3.50’/1.07m. All are distantly related to the CHASER 29, an IOR 1/2 ton design by Doug Peterson (1975).

27' Pearson Sailboat, 1988 ?? INFO, Opinion ??

  • Add to quote

I got looking at one, for sale, on line.. but I can't seem to find any info about the model . .. She looks real nice in the photos... Has a wing keel, diesel inboard... My concern? She was built at the end of Pearson's era... was she built like a Catalina.. aka the clorox of the sea? If you know ?? Thanks.  

eherlihy

Pearson, IMHO, was one of the better builders of their time. They were not designed to cross the Atlantic in a hurricane, but you don't want to be out there then either. Some of the best Pearson models were built at the end of the Pearson era (1987-1990). I would look VERY carefully at the deck, especially near stanchions, for soft spots, or delamination. Look at the boat inspection tips thread for a good explanation of what else to look for.

Jasper, I owned an 89 p-27 Wingkeel with a W-12B inboard extensively for 2yrs, Id be happy to discuss anything that I can tell you. Private message me if youd like, Id even been happy to discuss it via phone if youd find it helpful. Cheers AJ  

access to chainplates Is there a way to access the chainplates, rebed stanchions,etc without cutting into fiberglass? I'm looking at a 1987 Pearson 27, and am very interested in it. Thanks. Bonnie  

jackytdunaway

I rebed my stanchions 2 years ago using the Mainsail method. you can reach all the nuts by taking off the little piece of trim under each one that is attached to the liner. The chain plate come through the deck and turns into a rod the attached at the seat at the bulkhead next to the sink and the icebox. i have not done the chain plates yet. The stanchions at the bow and the stern are a little more trouble but can still be reached. no need to cut any fiberglass.
