Merit 25 is a 24 ′ 6 ″ / 7.5 m monohull sailboat designed by Paul Yates and built by Merit Marine Inc. starting in 1978.
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)

Review of Merit 25
Basic specs..
The Merit 25 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.
The boat can enter even shallow marinas as the draft is just about 1.22 - 1.32 meter (4.00 - 4.30 ft) dependent on the load. See immersion rate below.
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Merit 25 is about 102 kg/cm, alternatively 572 lbs/inch. Meaning: if you load 102 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 572 lbs cargo on the boat it will sink 1 inch.
Sailing statistics
This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.
What is L/B (Length Beam Ratio)?
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 17m 2 (182 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

The Merit 25 is a solidly built 25-foot sloop that seats five comfortably in a self-draining cockpit. Despite relatively simple control systems, the Merit has the durability and flexibility for comfortable, all-season sailing in the Bay Area, where typical wind speeds can range from near zero to above 25 knots. Spinnaker’s Merits are rigged for sailing in good daytime visibility under a full main and working-size roller-furled jib. Most of the club’s Merits can carry spinnakers as well. All the mainsails can be reefed for winds above 18 or so knots. In strong winds, the boat can be sailed comfortably under reefed main and reduced or completely furled jib.

Merit 25 - is it worth the haul?
- Add to quote
http://www.sailingtexas.com/smerit25j.html This is boat I'm looking at and I was wondering if its really worth the gas money and time to haul back to northern VA. Its been pretty hard to find one around here for this ones asking price. Looks to be in nice shape. If the owner met me 1/2 way would that help the deal? Any advice is appreciated. Thanks.
Of course, you might consider sailing her actually, and then a survey... if you agree on the price, then the half way meeting makes sense...
Come to Maryland There's a good looking Merit 25 for sale at my marina. I don't know the price but can send you the phone number for the owner so that you can talk to him directly. They are terrific boats, and nice looking too. It's on the hard at Oak Harbor Marina, Pasadena, MD (north of Annapolis.)

Pheonomenal Boat!
here in los angeles, my sailing school/club owns a number of merit 25's, and i've seen them at other sailing schools i've visited. i do not know why it's a popular school boat, but i'm sure it's not a coincidence. i am going to try one next week. it's a sharp-looking boat; but for now, that's all i know about them.

The Merit 25 is a multipurpose racer/cruiser that sacrifices very little with a large comfortable cockpit and high ballast to displacement ratio make it a confident and stable daysailor with a functional interior that invites weekend cruising. Merits 25’s have raced both PHRF and One-Design with outstanding success.
