Sandpiper 565

Sandpiper 565 is a 18 ′ 6 ″ / 5.6 m monohull sailboat designed by Leonardo da Costa Sayago and built by C&L Boatworks starting in 1972.

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)

The SANDPIPER 565 was first manufactured in 1972 by Sandpiper Marine Ltd. of Southampton, England. Later built by CL Sailboats (formerly C&L Boatworks) of Canada. (Royalties not paid) Another version was built under license in Sweden called OCKELBO OS 19.

Rigging instructions and general information Reproduced with permission for C&L Boatworks, Fort Erie Ontario

(Rigging Instructions from the Original owners manual - circa 1973) The SANDPIPER 565 sailing sloop was first manufactured in 1972 by Messrs. Sandpiper Marine Ltd. of Southampton, England, and was built under licence by C&L Boatworks located in Fort Erie, Ontario This seaworthy and stable yacht has many desirable features, and with its' retractable keel is so adaptable for trailering, launching and beaching that its owners can enjoy sailing in many different waters. Outstanding amongst its characteristics is the carefully designed and extremely dry cockpit with its high coaming for...

GENERAL RIGGING INSTRUCTIONS FOR SANDPIPER 565 Introductory Comments: In order that these instructions may be comprehensible to comparative newcomers to sailing, they are written in elementary terms and an attempt is made to explain the meaning of nautical words when they occur. Most experienced sailors have their own ideas on how to rig their boat, but these instructions are intended to provide a basis from which the new owner of a SANDPIPER 565 can begin. The mast when "stepped", i.e. erected, is supported by three wire stays collectively called the standing rigging. All three have an eye...

Shroud wires A7 are both the same lengths. Attach eye end A6 to mast tang A19 on each side Of mast at 3/4 height from mast heel using headed clevis pins and split pins. Insert shrouds A7 into slot in outboard end of spreader tubes AB and secure with split pins. -Set spreaders at right angle to mast and with downward tension on shroud wires tape together tightly.

Attach turnbuckle AID right hand...

2. Running Rigging and the Boom The running rigging comprises the halyards, which hoist the sails, and the sheets, which control their position when sailing. There are two halyards. One, which runs up the front face of the mast and down the back face, is the Main Halyard and consists of a wire with a braided rope tail, and is used to hoist the mainsail. The other halyard consists of a braided rope which runs outside of the mast through a swivel pulley located below the forestay wire mast tang. This the Jib Halyard and hoists the The boom is the spar, which is attached to the mast and to the...

The forward edge of the mainsail and jib is called the LUFF. In the case of the jib there is an internal wire running up the luff, whereas the mainsail has a rope edge (the luff rope) attached to the luff. The lower edge of the sail is called the FOOT, and the other edge the LEECH. There are four pockets extending into the mainsail from its leech and four battens are provided to stiffen the after edge of the sail. The corners of the sail are provided with eyes called CRINGLES. The top corner of each sail is its HEAD; the forward bottom corner its TACK and the aft bottom corner its CLEW. At...

open leech. If the sail has a very full luff, then a Cunningham line should be used to tighten the excess luff to flatten the sail for heavy airs. (b) Boom tackle: see figure 6 To control the extent to which the boom can lift when sailing, a tackle known as a kicking strap, or boom vang, is provided. In its simplest form it comprises a short wire strop attached to the mast bracket at one end and the other end of a vee jamb block with a "D" shackle and clevis pin. Another block with a special keyhole lug is snapped into the fitting underneath the boom. A lanyard is reeved through the two...

Having learned how to bend (rig) and hoist the sails by practicing ashore several times, the boat should be launched with the sails lowered. The boat should be secured to a dock or mooring. IT IS MOST IMPORTANT TO WATCH FOR LOW OVERHEAD HYDRO WIRES when stepping the mast prior to launching and again when lowering the mast after winching on a trailer, especially at an unfamiliar site. (a) Retractable Keel arrangement: see figure 7, The operation of the keel, which is raised and lowered manually, must be checked before preparation for sailing. Move the boat into minimum depth of 3 ft. of...

In light weather you should experience very little trouble with full mainsail and genoa in handling all points of sailing with your SANDPIPER 565. If you have been used to a lighter boat you will find the SANDPIPER 565 will take just that much longer to tack, gybe or bear off, so do not at first get too close to moored, or other craft while In moderate to heavy weather the answer is to reduce sail by reefing and to use a small jib. The method of reefing the mainsail has already been explained. To change jibs when afloat is rather difficult as it means going on the foredeck to reach the...

Review of Sandpiper 565

Basic specs., 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 Capsize Screening Formula (CSF)?

The capsize screening value for Sandpiper 565 is 2.67, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.2 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 Sandpiper 565 is about 66 kg/cm, alternatively 370 lbs/inch. Meaning: if you load 66 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 370 lbs cargo on the boat it will sink 1 inch.
