Sweet… Tison 48 Elida

Jag spanade ju in hans scow på Düsseldorfmässan för ett par år sedan. Han hade även en Class 40 på ritbordet.

Nu verkar det i stället bli en genlemannaracer till en tysk ägare.

Många saker som känns rätt här.

Hull lenght: 14.75 m
Hull beam: 4.55 m
Max draft: 3.2 m
Main: 77.4 sqm
Jib: 60.8 sqm

Målvikt är 7.8 ton på tom båt med 3.45 ton bulb.
Kan säkert variera beroende på vad inredningen landar på.

Man verkar ha tänkt mycket på vikten med däck i kol, ingen innerliner, 40 hk Lombardini och lättast möjliga system för el, vatten och annat. Thomas skojar lite om hur man kan spara 500 kg på en IMOCA. Måste ju betyda att något inte var optimalt från början.

Vi bollade lite kring olika byggtekniker…

We have compared the hull construction methods on a like to like basis, for a 75sqm hull prior to arriving at this solution:

Carbon sandwich (Nomex core): 470kg
Carbon sandwich (foam core): 520kg
Eglass sandwich (foam core): 590kg
Spruce single skin with carbon stringers and mahogany veneer (2mm thick): 785kg
Red Cedar Strip planking: 1.035kg

S.Y. ELIDA was created via discussion with her owner, an offshore racer with a taste for classic timber yachts. The vision of her owner was to create a true offshore racer cruiser, with all the recent advances in deck, rig and sail systems and construction methods found on the latest racing yachts but with a lightweight interior able to accommodate a family for short cruises and a timber hull construction and appearance.

We have devised a new construction method which results in a remarkably light and stiff hull for a timber construction, of less than 1t.

The hull shell is built from carefully selected spruce planks at +/-45 degrees and is supported by a network of closely spaced carbon continuous stringers. The material testing conducted at an Airbus facility, the density based material selection conducted by Jachwerft Koenigstein and the development of a specific lightweight epoxy based adhesive ensure the hull was built with the best possible available materials.

Due to the nature of this project, which maries both advanced composite components and high quality timber construction, TTYD early on proposed to assemble the skills of two yards. Jan Bruegge Bootsbau (Jachtwerft Koenigstein), based in germany, for the hull construction and assembly, and a specialist composite yard for the construction of the carbon parts (structure and deck).


In race mode, the forward cabin sole can be removed and the forward bed folded up and out, making this area ideal to store sails. Mattresses in the aft cabin can be removed and replaced by pipe cots, to provide sleeping capacity and the possibility to stack equipment/ sails when sailing. The chart table is placed remotely from the main action, the navigator can communicate with the cockpit via a dedicated portlight.

The navigation seat slides from tack to tack to ensure the navigator weight is to windward at all times. The interior arrangement was planned for using a spinnaker chute, creating a clear path between the foredeck hatch, wide opening in the mast bulkhead all the way to the aft watertight bulkhead. The table flaps, when closed, have a well rounded top edge without sharp corners to facilitate sail movements. The wet locker storage is heated, and the heating can be directed to a hand warmer by the galley.


The interior arrangement is an evolution of ELAN. It is unique in a sense that the navigation area is placed aft of the companionway, similarly to what offshore racing yachts do. This solution offers several benefits. Firstly it frees the space on starboard to create an “entrance unit’: This unit can be used for the electric panel, yachts papers, and above all a large, easy-to-access heated wet gear locker. Secondly, it frees the space for better movement around the companionway and to access the two aft cabins.

With the now wider hull shape, two symmetrical aft cabins were placed under the cockpit. A center console contains the engine and diesel tanks. Above this center console is a fabric storage which divides the two cabins visually. The choice was made to open the aft cabins to the main living area. This makes for an improved impression of space, and better ventilation. In the saloon area, a table hides the lifting keel structure and accommodates between 6 and 8 people.

The lower sofas on each tack are wide enough to be used as sleeping berths, the backrest can be lifted up to create additional sleeping capacity further up. Forward of the mast bulkhead is the heads compartment. Relatively large, it offers a shower floor area of 600 x 800mm. Space for a canting toilet was allowed for.

Opposite the heads compartment is a storage area, made of removable boxes which can be filled or emptied at home and brought in the yacht ready for use. It compensates the relative lack of storage space under the cockpit and offers better and easier access to the items stored. In the forepeak, a master cabin with a “V” berth can be found. Overall this yacht can sleep up to 10 people and is ideally suited for cruises for 4-6 people.
