Bluewater Sailboat – Ingrid 38

William Atkin’s Ingrid 38 is a heavy displacement blue water ketch influenced by Colin Archer’s famed double ender designs, which in turn were inspired by Viking boats known for their heavy weather characteristics. Perhaps Atkin’s best description is “the kind of boat that behaves herself in rough water and can be relied on to sail herself.” (In that section, we hear a lot about the excellent one-finger-on-tiller tracking and the comfy ride.)

She has an old world elegance and a sheer line that is evocative of Crealock’s famed Westsail 32. Her large keel, heavy displacement, and overbuilt construction demonstrate her seaworthiness. Her hull is hand laid in fibreglass, and she has strong outboard chainplates and an outboard rudder covered by extra fibreglass and a huge bronze shoe casting in case she scrubs the bottom.

Around 1934, American naval architect William Atkin was inundated with requests for a larger ketch-rigged version of his newly announced plans for the Thistle 31, a double-ender. Atkin designed the blueprints for the Ingrid 38 based on Archer’s lines.

The first Bluewater Ingrid 38s were made privately from blueprints in wood, steel, and cement, but it wasn’t until 1971 that manufacturing began in fibreglass by Blue Water Boats Inc. (ironically located in a town called Woodinville in WA). According to legend, the first Ingrid’s plug and mould were created by two Seattle sailors, James Musser and Donald J. Pitblado, while working together in a commercial chicken farm. The original idea for James Musser was to build Ingrid hull #1 and sail across the Pacific Ocean, but others were so fascinated by his Ingrid Sandaldust that they demanded duplicate hulls from the mould. Blue Water Boats Inc. was founded in response to this demand. Donald J. Pitblado, a coworker, went on to become the owner of Ingrid hull #2. Marie Donna

With 1973, the firm accepted Jerry Husted, a veteran Puget Sound sailor, as an equal partner, allowing Musser and his wife to sail away in Sandaldust to pursue their Pacific dream. Husted purchased the remaining shares in 1974, and the manufacture of the Ingrid continued until around 1985, when the moulds and patterns were sold and held for a long time in Graham, WA. Bill Ingerson purchased the moulds in 1997-98 and relocated them to Woodinville in 2000. Ingerson attempted to secure a few hull pledges but received little interest at today’s production costs.

The Bluewater Sailboat Ingrid 38 was built at a rate of one per month for 10-12 years, and there are thought to be 143 of these boats, as well as those made of other materials, still in existence. Many boats were purchased by Blue Water Boats as hull and deck kit sets and finished by their owners to a range of specifications and layouts (including using cutter rigs).

The Alajuela 38 is a variation on the Ingrid 38, with a hull that is a close derivative of the Ingrid, manufactured to a very high level, and outfitted with a cutter rig.

The key difference between Archer’s original design and Atkin’s Ingrid 38 was a better entry on the bow that ‘cushioned’ her landing off the waves. She features a long broad keel with deep v-sections ahead that keep her stable in the rough. The ballast is enclosed and dispersed from bow to stern, allowing her to avoid the pitching motion that fin-keel sailors are accustomed to. To top it all off, there’s enough of float fore and aft to keep her dry.

Performance

The compromise between heavy displacement and ultimate stability is generally speed, and the Ingrid 38 is not quick. Surprisingly, she sails admirably in light weather, with owners stating that she can sail at half the wind speed up to 8 knots of wind. She is, nevertheless, a boat that comes into her own in rougher seas. Her hull speed is 7.2 knots according to the figures, however, she usually cruises at a steady 6 knots. The ketch rig provides plenty of possibilities on all points of sail, and she’s a simple boat to sail solo.

Quick Notes

The Ingrid 38 is no longer manufactured, however, there are generally dozens available on the used boat market, primarily in the United States.

Review of Ingrid 38

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 Ingrid 38 is 1.53, 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 7.6 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 Ingrid 38 is about 225 kg/cm, alternatively 1262 lbs/inch. Meaning: if you load 225 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1262 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 Motion Comfort Ratio (MCR)?

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)

From BlueWaterBoats.org :

The Ingrid 38 from the pen of William Atkin is a heavy displacement blue water ketch derived from Colin Archer’s famous double ender designs, which in turn were inspired by Viking boats renowned for their heavy weather characteristics. Perhaps Atkin sums it up by saying it’s “the kind of boat that behaves herself in rough water and can be depended upon to sail herself”. (To that part we do hear frequent mentions of the superb one-finger-on-tiller tracking and a comfortable ride.)

With her old world style she’s a good looking boat with a sheer line reminiscent of the Crealock’s famous Westsail 32 . Her seaworthiness is there to see in her full keel, heavy displacement and overbuilt construction. Her hull is heavily hand laid in fiberglass, there’s robust outboard chainplates and an outboard rudder protected by extra fiberglass and a large bronze shoe casting should she scrub the bottom.

Atkin’s main rework on the Ingrid 38 from Archer’s original design was a finer entry on the bow which ‘cushions’ her landing off the waves. Below the waterline she has a long full keel with deep v-sections forward keeping her stable in the rough. The ballast is encapsulated and is distributed from bow to stern, this helps her to avoid the pitching motion familiar to fin-keel sailors. Rounding this off, there’s plenty of flotation fore and aft which helps keep her dry.

The tradeoff heavy displacement and ultimate stability is usually in speed, the Ingrid 38 is not considered fast. Surprisingly she’s known to sail pretty well in light airs, owners reporting she’ll do half the wind speed up to 8 knots of wind. However, she’s a boat that comes into her own in heavier seas. By the numbers, her hull speed works out at 7.2 knots but she’ll more often manage a consistent 6 knots while cruising. The ketch rig gives plenty of options on all points of sail and she’s an easy boat to single-hand.

Around 1934 American naval architect William Atkin was bombarded with demands for a larger ketch-rigged version of the Thistle 31, a double-ender which he had recently released plans for. Atkin took the lines of Archer’s design and drew the plans for the Ingrid 38.

The first Ingrid 38s were privately built from wood, steel and cement from the plans, but it wasn’t until 1971 that production began in fiberglass by Blue Water Boats Inc (ironically located in a town called Woodinville in WA). The plug and mold for the first Ingrid was built by two Seattle sailors James Musser and Donald J. Pitblado working together, as the story goes, in a commercial chicken coop. James Musser’s original plan was to build Ingrid hull#1 and embark on a Pacific Ocean cruise but others were so impressed by his Ingrid Sandaldust  that they requested similar hulls from the mold. From this demand Blue Water Boats Inc. was born. His co-worker Donald J. Pitblado went on to become the owner of Ingrid hull #2 Donna Marie

In 1973 the company took on Jerry Husted, an experienced Puget Sound sailor, as an equal partner which allowed Musser and his wife to sailed off in  Sandaldust to live their Pacific dream. By 1974 Husted bought the balance of the shares and production of the Ingrid continued until about 1985 when the molds and patterns were sold off and were stored for a long time in Graham, WA. Around 1997-98 the molds were purchased by Bill Ingerson and he shifted them back to Woodinville in 2000 . Ingerson tried to get a few commitments for hulls but never got much interest at todays production costs.

The Ingrid 38 was produced at the rate of one a month for 10-12 years and there are thought to be around 143 of these boats in existence as well as those constructed from other materials. Many boats were bought as hull and deck kit sets from Blue Water Boats and finished by their owners to a variety of standards and configurations (including using cutter rigs).

A variation on the Ingrid 38 exists in the form the Alajuela 38 , her hull being a close derivative of the Ingrid, built to a very high standard and configured with a cutter rig.

Buyers Notes

The Ingrid 38 is no longer in production but there are usually several available on the used boat market, mainly in the US. Current asking prices are around $35k – $79k USD.

Dose anybody have any input on a Ingrid 38 She is a nice double ender full keel 26,000 displacment 8,000 balist 11.4 beam Ketch. Please help if you can  

is the displacenent of 26,000 correct? eric  

Ingrids were an Atkins design from the 1930''s. Atkin really understood a lot about the Colin Archer types and had a wonderful ability to model yacht versons based on traditional working craft. The Ingrid is one of my favorite designs. They have been built and sold under all kinds of names and in a wide range of configurations. 26000 lbs sounds about right for one. The big problems with these boats were that they were designed for wooden construction. As it turns out, the wooden hulls were actually lighter than the glass hulls and so many of the glass boats are a little underballasted. The originals were pretty deep as well and so some of the knock offs are a bit shallower adding to this reduced stability. In their original form they had Ketch rigs that are the best of what a ketch rig should be. (Not my favorite rig as it gets interpretted on many boats) Still and all these are really bullet proof go anywhere types of boats. (To me these are what a 38 foot traditional boat should be if they really wanted to live up to their reputation.) Its not that they are perfect boats. They are quite slow by any modern standard. Because of they are double enders, the interior and cockpit are a little small, and they tend to be a little wet. Still in all these are really neat boats if your goal is to really do some long distance voyaging on a traditional low tech boat and you really don''t care when you will arrive. Jeff  

Jwff:The Ingrid is not one of the boats I''ve owned;That said,my father-in-law,who was an excellent shipwright and boat yard owner in Portland,Or. built one in wood,using Port Orford cedar on steam-bent oak frames and copper fastenings.We sailed it up the coast to Victoria B.C. and then left it in Port Townsend for about 5 years using it every time he or I could get away.It was built to spec''s and although under powered by modern expectations it actually sailed quite well,in any direction,except down wind,then the mizn. was blanketed.In wood I would say they were about a 25% better boat than in Glass!  

I''ve been looking at Ingrids myself. Here''s a website with a lot of info about the Ingrids and their sister ship, the Alejuela 38s. The site is run by a guy who''s finishing off an Ingrid hull.... http://hood.hctc.com/~esteve/ ....There''s also a chapter about the Ingrids in Ferenc Mate''s book "Best Boats to Build or Buy" that tells how they are constructed.  

Gene, Copper rivetted cedar on oak, it doesn''t get much better for these boats (except that a friend of mine built a cold molded port orford cedar version in the 1980''s). I think that we are in agreement that the wooden versions were probably better sailors although I suspect that 25% better is probably a bit on the high side. Regards Jeff  

Not so Jeff! When they build them in plastic they always seem to change the run aft and that makes them dogs to sail compared to the real deal!!  

I single handed my Ingrid 38 from Puget Sound to La Paz Mexico. I averaged 6.4 knots over the ground. Mine was an owner finished boat that did the south pacific. The factory finished boats (in my opinion) were designed to sell in the late 70's and 80's. They had to many berths and not enough living space. I used a monitor windvane and a autohelm 2000 for the tiller. The ingrid is not a marina queen and is dificult to get into a slip. You make your turn and then throw it into reverse and walk her around to line up with the slip. I single handed a lot.  

I just acquired a wood Ingrid built somewhere between 1960 and 1980. She is closer to 42ft and I am having a hard time finding out where she was made and by who. Do you know a site that has some sort of history on them? Thanks!  

Seems like a great, nicely updated boat. My PSC34 was about twice the price (and of course about 15 years newer), but not as well equipped or updated. Wish I had had a choice of this Ingrid.  

says the site is not found....  

Have you seen this boat?  

There's currently an Ingrid on CL up in Anacortes. https://seattle.craigslist.org/kit/bod/d/38-ft-ingrid-38/6275267702.html

Thank you Deina. The other Ingrid listed here in Winchester Bay, OR I went to look at. The day I arrived, according to the seller, motor stopped working! So no sea trial.  

FWIW, the Ingrid design was Atckin's best double ended design. The longer length allowed finer bow sections so less hobby horsing and significantly better windward performance than his Eric/Thistle design from which the Westsail 32 originated. The boats are initially tender as are all slack bilged, wind glass form boats. They stiffen up as heel angle increases and most importantly have excellent ultimate stability. How tender the fiberglass hulled Ingrids are or how in relation to the wooden ones is something I'm not familiar with. One thing about the FRP home builts is most used steel as the ballast and it was spread out. Steel doesn't weigh as much as lead so doesn't work as well against heeling and spreading it out increases the tendency to hobby horse because of adding weight closer to the ends. Alajuela attempted to counter the steel ballast issues by using all lead ballast more centrally located as did the later Westsails with cast lead ballast. It's not a case of one is bad and the other good but that lead is better than steel/iron ballast given the choice. Unfortunately you'll have to live with whatever ballast the boat has. We sailed an early W32 with about half lead and half steel ballast. It sailed fine given the limits of the hull design and was faster than most other boats, except going hard on the wind, of it's water line given more than 10 knots of wind and skunked almost all other boats on a beam to a broad reach with the exception of ULDB planing type hulls, in higher winds. The Ingrid is a great Tradewind boat and should sail better to windward than its shorter siblings. It will not be a great light air boat because of its wetted surface but then no full keel boat is without a very high sail area to displacement ratio. Using large light air sails will help but will never overcome a newer boat with deep short keel with a bulb and a very tall stick and large sail area.  

I own a 38 catch I believe that's the same specs unfortunately I have to sell it in the next year I'm looking to find a good home for her
