Though only a few are presently translated, equivalent information in English is available from other sources. For example, the websites of epoxy suppliers give comprehensive information in regard to saturation, gluing, filleting, and sheathing.

Dimensions Hull length 4.44 m Waterline length 4.10 m Breadth 1.70 m Depth 0.68 m Draught (centreboard up) 0.25 m Draught (centreboard down) 0.86 m ISO Light weight (clinker) 245 kg ISO Light weight (strip planking) 300 kg Sail area standing lug 12.2 m² Sail area lug yawl 12.4 m² Sail area sloop 14 m² Note: the ISO light weight includes the full rig (standing lug option), anchoring line and basic mooring equip- ment. This weight may vary according to plywood and timber choice. Thus, it is recommended to weight the boat prior ordering the trailer. Add 11 kg for the sloop version. It is possible to save 10 kg with a reduced thickness of floorboards (see ap- pendix 1). 2.2. Boat presentation Ilur was designed as a family day sailing boat. It can be used for fishing and even coastal cruising. Two Ilur have been to Ile of Sein, at the extreme West of France, one of the worst place to go with tremendous tides and sea conditions. However, do not consider this as an invitation to go there ! Ilur has good seakeeping abil- ity, but still in the sail and oar spirit. Its superior quality makes Ilur my best-seller plan (with nearly thousand copies sold). It has been built in many places, from the very heart of Alps, to Pacific islands! If you have to choose the best boat for your intended use, just notice than Ilur is not an easygoing rowing boat compared to others of my sail and oar designs. She is mainly intended for sail, oars being used when wind is falling or to reach some narrow inlets. Ilur was designed at first with the simple standing lug sail in the Breton style (said “misainier” rig). A lug sloop rig is now proposed and is a valuable option. A balanced lug rig (lug sail with boom) is an other option, interest- ing for river or single-handed sailing. 2.3. Ilur clinker version built from a kit This set of documents describes a new version of Ilur, said clinker kit, which is clinker built and available only as a CNC (numerically controlled machine) cut plywood kit. Main changes and improvements are as follows: ✔ Construction from a refined plywood kit allowing a dramatic decrease of the building time. Laminated or steam bent frames are replaced by a few plywood frames, ✔ Locker afterwards, ✔ New pivoting centreboard and rudder, ✔ Oar stowage above or under floorboards, ✔ Building manual with 3D sketches, ✔ Choice between 3 possible rigs. Ilur has been improved many times from the first design in 1988. So be careful when looking at other Ilur and pictures and do not copy without checking it is appropriate.

Classic Ilur Apart from the new clinker kit Ilur, the previous Ilur design, now named “classic Ilur”, is still available. Classic Ilur: ✔ Is built either strip planked or plywood clinker ✔ Has laminated or steam bent frames giving a very traditional and beautiful look. ✔ Is built from plan package only (different from the Ilur clinker kit). ✔ Full size patterns on mylar (polyester sheet) are available as an option. 2.5. Compliance to regulations WARNING Ilur is a boat that may capsize. It is important to be always vigilant at the helm and always ready to release the sheets. Carry an amount of sail appropriate for the wind and the sea state, particularly if no external assistance is available. Moreover, it is necessary to be ready beforehand in the event of a capsize, most particularly in regard to righting the boat, calling for help, and ensuring the survival of the crew. Ilur is designed in compliance with the requirements of the European Recreative Craft Directive 1994/25/CE amended 2003/44/CE. It is designed to sail in the following categories: ✔ In category C, with a maximum of 3 persons on board (maximum loading 275 kg) ✔ In category D, with a maximum of 5 persons on board (maximum loading 425 kg) The minimum crew is one person, as the boat may be right up by one person only in calm sea conditions. It is recommended to be at least two on board when sailing in poor wind and sea conditions or away from any pos - sible assistance. Attention : it is recommended to keep on board a piece of cloth to be inserted into centreboard case in order to avoid water entry after capsize and ease bailing out. Ilur may receive a motor of maximum power 4.4 kW / 6 hp (long of short shaft). A 2 to 3 hp motor is preferable, being lighter and easier to handle. The definition of these categories is pointed out below: Category C (Inshore): designed for trips in coastal waters, large bays, estuaries, lakes and rivers where condi- tions up to, and including, wind force 6 and significant wave heights up to, and including, 2 m may be experi - enced. Category D (Sheltered waters): designed for voyages in close coastal waters, small bays, lakes, rivers and canals where conditions up to and including wind force 4 and maximum wave heights up to and including 0,3 m may be experienced. NOTE: The significant wave height is the mean height of the highest one third of the waves, which approxim- ately corresponds to the wave height estimated by an experienced observer. Some waves will be double this height. This document is the property of François Vivier Architecte Naval.
