Allegro 33 is a 32 ′ 2 ″ / 9.8 m monohull sailboat designed by Lars Olof Norlin and built by ACVA-Båt (SWE) between 1970 and 1985.

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)

Broker's Comments

This boat has been viewed and photographed by Gary of Boatshed Algarve. Register or log in to see more photos of this boat. These boat details are subject to contract. Sweden is proud of its sea faring heritage, renowned for building to a high and solid standard. This Allegro 33 off shore cruiser is no exception built by ACVA Boat Builders in 1980. The knowledgeable and much travelled owners have enthused about adventures cruising around the world in her, which began in 1998 after a major refit, they now have need of a larger boat with more cabins due to increased family visitors needing to stay over. The main area is quite spacious for a 33 with plenty of locker space including hidden storage space for the odd bottle of rum or two. It has an ample galley in the cabin with all the creature comforts such as oven, fridge and cooker also cabin heat for those chilly January mornings here in the Algarve or all year if you live in Sweden. The navigation table is opposite the galley which leads through to the comfortable saloon and then forward to the V-berth double cabin. This is an easy to handle cruiser with an excellent sailing pedigree that will suit many .

It should be noted that the substantial Force Four dinghy/rib and new outboard are negotiable separately.

Note: Close offers on the asking price may be considered.

Beneteau 13.5

We have three photos of one boat with a Monitor.

Images of Monitor: 3

Beneteau 13.5 Monitor "Whisper" - Seattle, Washington

Allegro 33 Monitor "Gormlaith" - Mariestad, Sweden. This Monitor was shipped to Jorgen Sandgren in 1988. Jorgen went off cruising, and in 1997 we heard from him in Fiji. He's currently based in New Zealand, cruising the South Pacific every six months. "Gormlaith" is the name of an early Irish queen, beautiful, scheming and wicked. Her history is too complex to describe here.

Description.

Classic pointed-hole sailing yacht. Built in Sweden by the ACVA - Bat yard. The long, deep keel, guarantees an excellent seaway. Many innovations and improvements have been made by the current owner.

The cockpit is robust and sheltered, thanks to the high backrest and substantial tiller gives a safe impression, the lines have been brought to the cockpit by her current owner.

The cockpit is robust and sheltered, thanks to the high backrest and substantial tiller gives a safe impression, the lines have been brought to the cockpit by her current owner. The deck has non-slip paint and there are several handles on the cabin. The book is spacious and equipped with a solid fixed bowsprit. The interior is light and spacious for her length (and age) thanks to the substantial width, the saloon can be called generous. On the port side a simple galley with running water and 2-burner stove with oven. There is also room for a future cooler. On the other side is the navigation table and dog cage, thanks to a porthole under the cockpit bench, extra light can be created here. After the saloon with U-sofa and longitudinal bench (with pilot berth), the double V-bed is situated in the bow, equipped with spacious hanging locker and access to the lockable toilet room.

The Allegro 33 is a special appearance and very suitable for longer (sea) trips. She joins the ranks of the Olle Enderlein 32, Grindes and is particularly complete and ready to go.

Review of Allegro 33.1

Basic specs..

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well. The boat is equipped with 6 berths. Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

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 Allegro 33.1 is 1.89, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Allegro 33.1 is about 218 kg/cm, alternatively 1225 lbs/inch. Meaning: if you load 218 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1225 lbs cargo on the boat it will sink 1 inch.
