Puut ovat kuivia !!! The wood is dry and ready for use !!

Elokuussa 2014 puumateriaali oli kuivunut n.1.5 vuotta ja oli aika palata EVOlle valitsemaan runkolaudat ja pakata mukaan kaikki muu tarvittava puumateriaali.

Otimme mukaan kaikki kaarimateriaalin kuten myös sivusarjat ja kattomateriaalin.

Runkolautojen valinta oli pitkä prosessi koska laudan tulee olla suora, leveämpi kuin 30cm ja halkeamia ei saa löytyä...Meillä oli 80 lautaa josta valitsimme 36 loppujen lopuksi. Runkoon menee noin 40 lautaa. Onneksi meillä on muutama lauta Askolan sahalta joten määrä pitäisi olla riittävä.

-------------------------------------------------------------------------------------------------------------------------
In August of 2014 we returned to EVO to pick up the materials. The material had dried up naturally for about a year and a half and was now ready for use.

The frames, deck and cabin top materials were straight forward as we took everything we had cut down but lot of time was spent in selecting the planks suitable for the hull. We were looking for straight planks that were at least 30 cm wide and must not have any cracks...

It became evident that the process of drying the lumber is very difficult to control as many of the planks intended for the hull had cracked in the process. 

We had 80 planks for the hull to begin with and ended up with only 36 that were in good shape. The hull will need about 40 planks total...we do have a few planks from the other sawmill so we should be in good shape.



Runkolautojen tarkastus...Inspecting the hull planks






Kaari-, peräsin- ja perälautamateriaalia

Frames, rudder and the transom will be made out of these planks


6 tuntia työtä ja materiaali on kasassa, valmiina toimitukseen

6 hours of work and we got everything piled up, ready for delivery


Kajuuttojen kattopalkkeja

Beams for the cabin-tops

Maston osat / Spars

Masto ja puomit kaadettiin Paraisilla talvella 2014. Hitaasti ja suoraan kasvanut kuusi on hyvä materiaali joustavuutensa takia. 

Nämä nostettiin sellaisenaan veneveistämön vintille, jossa ne myös työstetään aikanaan oikeisiin mittoihin. Vasta kaadettu puu on suht' painava ja vaati useamman miehen nostourakkaan..
---------------------------------------------------------------------------------------------------------------------------
The spars were cut down in the winter of 2014 in Parainen, south of Turku. Spruce makes for a very good spar material due its strength against stress and it typically grows very straight... 

The spars were lifted up in the attic of the workshop to dry. They will be milled down to the desired dimensions later on. Solid pieces of timber required a bit of manpower to get them up into the attic...

Puut kaatuu...Timber !!

Sydäntalvella 2013 palasimme EVOlle jossa ennalta valitut puut kaadettiin ja sahattiin oppilastyönä.

We went back to EVO in January of 2013 where the pre-selected trees were cut down and taken to the sawmill by the students of the Forestry-school

Puut sahattiin ja tapuloitiin kuivumaan.

Trees were sawn to planks and stored to be dried out / cured.




Tämä kyseinen puu jäljitettiin vuoteen 1833.
This tree was traced back to 1833. We had several trees of around this age








Sopivan materiaalin löytäminen, The search for building materials

Veneenveistäjä on Marko Nikula Turun Littoisista (www.veneenrakentaja.com) ja suunnittelijana toimii Harro Koskinen, jolla on monen vuosikymmenen kokemus perinnealuksista.

Talvella 2012-2013 etsimme rakennusmateriaaliksi sopivaa, vanhaa mäntypuuta etelä-suomen alueelta ja etsinnän tuloksena päädyimme EVOn kansallispuiston metsäkoululle ja Porvoon Askolaan. 

Molemmista paikoista löysimme vanhaa, hitaasti kasvanutta mäntyä.






The boat will be built by Marko Nikula who has his workshop in Littoinen, close to the city of Turku in Finland. (www.veneenrakentaja.com). He has built several smaller traditional vessels. The designer of the boat, Harro Koskinen, has several decades of knowledge and history with the traditional boats and he has designed many of the replicas over the years. 

In the winter of 2012-2013 we scouted around Southern-Finland for suitable building materials. The type of wood we were looking for is old, slowly grown Nordic Pine for the hull and frames and Spruce for the cabintops and spars.

The search lead us to a Nature Reserve (EVO) that runs a school for forestry and the other source was a private sawmill in the town of Askola near Porvoo.

The Project

Storbåt Tacksamheten - projekti (English translation added on the bottom of the page)

Venemalli pohjautuu Saaristomeren perinteiseen Markkina-/rahtivenemalliin joka tunnetiin yksinkertaisesti nimellä Storbåt.

Näitä veneitä oli saaristokunnissa käytössä 1500-luvulta aina 1900 luvun alkuun asti. Näistä veneistä on kirjoitettu erinomainen kirja nimeltä "Storbåt, förr och nu" Per-Ove Högnäs & Jerker Örjans.

Veneemme Tacksamheten pohjautuu suunnilleen kirjassa mainittuun samannimiseen veneeseen joka rakennettiin Nauvossa vuonna 1825 Kökarilaiselle omistajalle. Kyseisen veneen mitat olivat :

- Pituus : 12m
- Leveys : 4.5m
- Syväys : 1m

Pienten muutosten jälkeen veneemme sai seuraavanlaiset kokonaismitat:

- Pituus : 12.5m
- Leveys : 3.6m
- Syväys : 0.9m

Paino asettuu noin 7,000kg kohdille, josta painolastia on noin 1,100 kg

Kokonaispurjepinta-ala on 60 neliötä josta isopurje on noin 40 neliötä.

Veneeseen tulee myös apumoottori, 10kW DC sähkömoottori. Akkukapasiteetti on mitoitettu noin 4 tunnin ajoon (6 solmun vauhtia).

Projekti alkoi talvella 2012 jolloin puut kaadettiin. Rakentaminen alkaa lokakuussa 2014 ja purjehdusvalmiina vene on kesällä 2016.




The boat design is based on the traditional Baltic sea small-trades cargo vessel. These boats were very common within the island communities between Finland and Sweden and were used to relocate the livestock from island to island as well as take the goods to the mainland to be sold. 

This type of boat remained relatively similar throughout its history which spanned between the 1500s to early 1900s. The changes on the design had to do with the number of planks / side and the type of rig. The early boats had only 5 planks / side and a square rig. A removable freeboard provided added safety during the voyage. Later on the standard settled at 7 planks / side + the removable freeboard and a low-aspect ratio gaff rig.

A very comprehensive book about these boats has been published "Storbåt, förr och nu". It is written by Per-Ove Högnäs & Jerker Örjans.

In that book a boat named "Tacksamheten" (appreciation, gratefullness) is mentioned. This boat was build on the island of Nagu in Finland in 1825. The owner of the boat lived further south on the outer islands of Finland in Kökar. The boats on the outer islands were commonly a bit larger due to the fact that they were sailing in more open-sea conditions. The original Tacksamheten had the following dimensions:

- Length : 12 m
- Beam : 4 m
- Depth : 1 m

Aiming for better speed and maneuverability we ended up with :

- Length : 12.5 m (the hull is 11.5m)
- Beam : 3.6 m
- Depth : 0.9 m

The weight is estimated to be about 7,000 kg out of which the internal ballast will be about 1,100 kg. The sail area is 60 square meters. The main sail is 40 square meters in size.

We will have an auxiliary engine (10kW DC electric motor). The battery bank is sized to allow 4 hours of cruising at about 6 knots.

The project started in the winter of 2012 when we selected and cut down the trees and the construction / building of the boat will commence within a couple weeks in October of 2014. The 1st sailing will take place in the summer of 2016.
