A type, not a builder
"Lemsteraak" names a Dutch flat-bottomed sailing type, not a company's product line. The Stichting Stamboek Ronde en Platbodemjachten -- the Dutch national registry for round- and flat-bottomed traditional sailing vessels -- classifies it plainly as a scheepstype, or ship type, filed under the broader category "Aken." (It is also known, more simply, as a "Lemmeraak.") No single yard has ever branded boats under that name as a proprietary marque; instead, distinct and unrelated builders have built to the type across more than a century, from the De Boer family's Lemmer yard to Hindeloopen's Skipshelling Blom to Amsterdam's G. de Vries Lentsch.
What makes a hull a lemsteraak
The defining trait is a flat bottom, drawing as little as 38 centimeters -- shallow enough for the Zuiderzee's inshore waters, and shallow enough that the type carries hefty leeboards in place of a fixed keel. The hull is decked forward of the mast and, as a rule, built with a bun, a fish well; for the herring catch specifically, boats instead towed tender boats called haringvletten rather than carrying the catch aboard. The rig steps a mast without a standing backstay, flying a gaff mainsail with a staysail and jib -- a gaff rig chosen, on one account, because builders simply were not able to make masts tall enough for anything else, and curved for aerodynamic effect to compensate. Construction today still divides along a fixed line: class rules require the mast, leeboards, and rudder to be wood, while the hull itself is always steel. Yachting historian Hal Sisk offers a further wrinkle on the type's working purpose -- in his account, the Lemsteraak was not originally a fishing boat that caught fish itself, but a seagoing carrier built to move fresh fish and mussels from the working fleet to market as quickly as possible.
Origins: a fishing aak and a separate pleasure-yacht name
The hull type traces to the second half of the 19th century, developed from the visaak of the Frisian inland waterways for fishing the northern Zuiderzee between Lemmer and Den Helder. Pier Klazes de Boer opened a wooden shipbuilding slipway in Lemmer in 1876, riding the rise of Zuiderzee fishing, and the iron fishing aken his yard went on to build carried a recognizable enough design to be seen as a distinct vessel type in their own right.
The name itself has a separate, later history. It does not appear anywhere in Lemmer's municipal reports; its earliest documented use is 1898, in a local sailmaker's cutting books, for a pleasure yacht built for a Belgian client -- not a fishing boat. That single early instance sat apart from the wider adoption of "Lemsteraakjacht" as a name, which only took hold after World War II, once large steel-iron boeieraken had replaced the big wooden pleasure boeiers of the early 20th century. Because those large boeieraken existed alongside the type's plainer fishing craft, a Lemsteraak could mean either a simple fishing aak of about 12 meters or a luxury pleasure yacht of more than 17 meters.
That pleasure lineage produced the type's best-known individual boat. The royal boeieraak De Groene Draeck became the norm the SSRP measures a Lemsteraak's proportions against -- a standard strict enough that an original fishing aak from Lemmer could be, and was, rejected by the Stamboek registry if its hull proportions deviated from De Groene Draeck's own. That yacht's hull was drawn by Lemmer shipbuilder Ary de Boer and built at G. de Vries Lentsch's yard in Amsterdam; it slid down the ways on 4 June 1957 and was handed over at Muiden eleven days later, on 15 June. Its hull is that of a Lemsteraak; its rig and superstructure are those of a boeier yacht.
Construction through the eras
De Boer's own construction methods shifted along with the type: earlier boats were built by eye, using old molds, before the yard moved to building from drawings. Pier Klazes de Boer decided in 1899 to add iron ships to the yard's wooden output, and after 1900 Lemsteraken were, as a rule, built in steel. Across Pier Klazes de Boer and his sons' combined output, the yard built roughly 250 Lemsteraken, wood at first and iron from 1900 on. The sons formalized that iron-era shift into a new shipyard of their own, built next to the old slipway in 1901; the brothers went their separate ways in 1925, after a period of sharply reduced activity following World War I. The last Lemsteraak came off the slipway in 1960 -- build number 774, the Vrouwe Hendrika, 11.50 by 2.80 meters, with 80 square meters of sail and a 51-horsepower engine -- the same year Ary de Boer sold the yard to the firm of Hilbrand Poppen, of Obergum/Winsum.
Elsewhere on the IJsselmeer, Skipshelling Blom has operated from Hindeloopen since 1957, specializing in steel hulls built technically ready to sail, including Lemsteraken to its own design; Dirk Blom's family has built them there since 1967, after his grandfather, a fisherman, inherited the yard once the IJsselmeer dyke was built. The type has kept evolving under yards like Blom's: naval architects Van Oossanen ran a full computational fluid dynamics analysis and design optimization on the Lemsteraak Warber before construction began, which the firm's director, Niels Moerke, described as the first time CFD had been applied to the class. Even so, the class holds a hard line elsewhere -- the SSRP maintains traditional vertical-cut sails for the Lemsteraak class, resisting the modern sail-design arms race other classic classes have adopted.
Who a lemsteraak is for
Lemsteraken race actively on the Netherlands' inland waterways, typically every other weekend, often completing three to six races over a weekend and drawing fields as large as 33 boats to a competitive start line. That makes the type suited to a sailor drawn to a documented, actively raced Dutch traditional-sailing class under national registry oversight -- a hull-and-rig heritage maintained by SSRP class rules and a scattered community of yards, rather than the engineering pedigree of any single company.
