1973 Norlin 41

• Description

Seller's Description

Norlin 41 (made by Lemvig Boat works in Denmark) - similar to the Swan 41, available for sale in Ohio. USCG documented. A vessel appraisal provided by the seller from October 2021 has valued the vessel at $34,900. The seller has priced the boat below that as he’s hoping for a quick sale.

Best features of the boat per the seller: It is set up very nicely for sailboat racing (PHRF rating was 93 last time it was rated), while still being comfortable to stay on for weekend cruising.

The boat was mainly used for racing and short term cruising around Lake Erie. The boat comes with a storage unit’s amount of gear. The storage is near the boat and contains all of the gear for the boat, including multiple sets of sails.

MISC Specs:

Passenger Capacity: When racing, 4 to 8 people on board.

Sleeping Capacity: “officially” it can sleep 9 simultaneously, however in practice, it is comfortable to have 4 people sleep on board at any given time.

When racing we would only ever have all 8 people sleeping at the same time when we were at the dock overnight before a race.

Waste capacity: Currently none when there was a bladder tank, it was 15 gallons # of cabins: 3 (V-berth, aft cabin, main) closing doors between each for a bit of privacy # of berths: Officially 9 (see comments above) V-berth: 2 Main cabin: 5 (one settee makes into a double, and it has sea berths above the settee berths) Aft cabin: 2

ENGINE Specs:

• 1973 Farymann Diesel S30
• Raw water cooled
• No hour meter so hours are unknown. The engine was mostly used for docking and getting out to the race start/finish line.
• Fuel burn: unknown - The Seller was collecting data on this but the notebook was lost when they moved from Ohio to Maryland
• Drive type: hydraulic pump
• Cruise speed: ~5 knots (under engine alone. With only sail, it generally goes between 5 and 9 knots, I have achieved a max speed of 10 knots)
• Max speed: ~7 knots (under engine of course)

The engine is not the common Yanmar or Volvo, but the Farymann is a very simple engine with very little to go wrong and it has never given me any problems. The design for the Farymann engine was bought by a generator company (Entec) who still manufactures and sells new parts for it.

Electrical system:

• Currently no batteries on board, has room for 3x Group 31-sized batteries
• No generator
• Alternator was replaced by the previous owner, I do not have any details off the top of my head on it
• Battery charger: charger with stages for AGM charging algorithm
• Circuit break panel is at the chart table
• Deck lights on the lower set of spreaders, cockpit itself does not have a light
• Navigation lights are installed and functioned properly the last time I used them
• Several 30 amp shore power cords come with the boat
• Stereo system on board is in the main cabin with two speakers only

Navigation Equipment:

• Standard Horizon VHF radio with AIS and GPS
• Compass in the cockpit at the pedestal
• Autopilot (the kind that goes on the wheel) (autohelm 3000)
• Speed/depth transducers
• Handheld spotlight and a few connectors around the boat to plug it in

Accommodations:

• Galley has sink, propane stove with oven, pull out cutting board, lots of storage for dishes/pots/pans, there is an icebox with no refrigeration (this could be upgraded easily enough by the new owner)
• Pressurized water throughout the boat (at galley and in both heads)
• Sinks in both heads as well as the galley
• There is a folding table that goes in the main cabin around the mast, both sides lift up
• 120v AC outlets on board (no inverter)
• 12v DC system
• 2 anchors, 150’ of 3/4 line for the 35 lb, and 50’ of r for 15 lb.
• Propane magma grill (circular type)

Safety Equipment:

• Handheld searchlight with connectors on deck to plug it in (not cordless)
• Handheld air horns (canned air type)
• Bow pulpit and stern pushpit are stainless steel tubing, stainless stanchions and lifeline run perimeter of deck

Sailing/Rigging Gear:

• Mast is Black Aluminum, keel stepped, hydraulic back stay, roller-furler
• Harken forestay, Aluminum boom, stainless steel chain plates shrouds to hull stringers
• Forestay to a stainless nose plate, Aft chain plate is molded to transom
• Spinnaker pole and strut
• Boom Vang, Lazy Jacks and reefing lines, single line reefing, multiple reef points
• Feathering prop with two blades
• 10 Lewmar winches - none are self-tailing
• Sail cover for main sail, genoa has a UV cover for roller furling
• Ballast is a fin keel made of lead
• Sheets and halyards are all included (along with all rigging required to sail the boat, most is not on board currently, but in storage)

Most recent full bottom job was in 2006 by the previous owner. Stripped down and coated with 12 coats of 2 part barrier coat, and 2 coats of VC17 every season she’s been in the water. They continued painting with VC17 every year that she was in the water.

The following items were done by the current owner:

• Updated through-hulls and seacocks (groco bronze) for 7 of the 9 total on the boat (finished end of last year)
• New engine intake and exhaust hoses (finished earlier this year)
• Replaced engine intake raw water strainer (finished earlier this year)
• Changed impeller annually
• Changed oil + filter annually
• Upgraded starboard side engine mount (two years ago)
• Removed the old bladder holding tank due to age and they are known to leak eventually (ours never did but we wanted to remove it ASAP) along with all plumbing for both heads - have not replaced
• Removed a cracked forward head (the bowl itself was split) - have not replaced
• Replaced VHF with AIS/GPS and RAM mic in the cockpit
• Replaced speakers for the stereo in the main cabin - the head unit is fairly old but it didn’t need to be replaced
• replaced some deck coring near the mast and deck prisms

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 Norlin 41

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The boat is equipped with a galley and toilet facility.

The Norlin 41 is 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.

The Norlin 41 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 full keel.

The boat can only enter major marinas as the draft is about 1.95 - 2.05 meter (6.40 - 6.70 ft) dependent on the load. See immersion rate below.

Norlin 41 may be equipped with an inboard Farymann engine at 25 hp (18 kW). Calculated max speed is about 4.9 knots

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 Norlin 41 is 1.90, indicating that this boat could - if evaluated by this formula alone - 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 7.9 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 Norlin 41 is about 278 kg/cm, alternatively 1558 lbs/inch. Meaning: if you load 278 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1558 lbs cargo on the boat it will sink 1 inch.
