VENDIA has drawn attention on the international markets once again. Wooden Boat magazine published a very interesting article about VENDIA marine plank in November/December 2014 issue. The article was written by Richard Jagels, an expert in a field of woodworking industry and emeritus professor of forest biology at the University of Maine.
According to Jagels, VENDIA marine plank resembles exterior-grade plywood but differs in features and appearance from normal plywood. Normal exterior-grade plywood is made of a rotary cut veneers whereas VENDIA marine plank is made of sliced veneers. Jagels shows his expertise by highlighting the weaknesses of rotary cut veneer. One of the problems is that it is kind of broken wood which means that the surface of the veneer includes small checks. After drying and flattening into plywood panels these checks will open and expose the plywood panel to decay fungi. As a result the paint or varnish can be damaged over time.
Since VENDIA marine plank is made of sliced veneer the structure of the wood remains solid and check-free giving VENDIA the outlook of sawn wood. Knot-free veneers are always selected as face veneers which also makes VENDIA marine plank very durable. Regular structure of VENDIA marine plank makes bending of the plank a lot easier compared to traditional sawn wood plank.
Jagels brings out also the MUF-glue used in VENDIA marine plank. MUF-glue has extremely good tolerance of humidity and weather condition changes. The glue provides also esthetically beautiful outcome. MUF-glue is transparent and makes the joints unnoticeable. Traditionally used dark-coloured phenol formaldehydeglue makes the joints very dark. VENDIA has passed glue boiling tests and complies with the technical requirements of British standard BS 1088 used in marine planks.
Jagels has presented the technical features of VENDIA marine plank very extensively and with great expertise. It has been our pleasure to read an article like this here in VENDIA. Full text article can be found by clicking here >>.

VENDIA sails to the seas
Students of Etelä-Kymenlaakso Vocational College, Paavo Koivisto and Jouko Pohjolainen, are currently building a coastal rowing boat made of VENDIA marine plank. The goal of boatbuilders is to get the boat ready for the Helsinki International Boat Show in February 2015.
Koivisto and Pohjolainen are currently building the boat of 12 mm VENDIA marine plank. The boatbuilders are of the opinion that the thinner VENDIA, such as 9 mm would be also suitable for this kind of boat. However, thickness of the marine plank increases the stability of a coastal rowing boat and therefore they decided to go with the 12 mm VENDIA. Experiences of the boatbuilders have been positive. Beautiful appearance and workability came first to mind of Koivisto and Pohjolainen. They also liked the knot-free surface since there is no need to patch up branches like in the normal plank board.
Comments of the boatbuilding teachers from the Etelä-Kymenlaakso Vocational College were also positive. “Good looking material”, said the teachers. According to the teachers high-quality traditional plank boards are very hard to find and VENDIA marine plank is considered as a welcome novelty for wooden boatbuilding. When building a wooden boat it is ideal to find marine planks as long as the boat is. Unfortunately in case of six-meter-long wooden boats this is not possible in most cases. This was a concern of the teachers.
There are two restrictive factors to get the six-meter-long marine plank. First, there isn’t such long slicer in the world. Another limitation is related to the delivery costs. Costs of packaging and transportation of six-meter-long planks would rise up to fivefold compared to three-meter-long packages.
VENDIA marine plank is available in lengths of 2 600 mm and 3 000 mm. Scarf jointing is easy and simple way to lengthen a marine plank. Thanks to VENDIA’s thick face veneer the scarf joint is quite undetectable. From the pictures above you can easily see the appearance of scarf joints when VENDIA marine plank is used.

VENDIA in British Water Craft magazine
VENDIA has
drawn attention also on the international markets. Recently a British Water Craft magazine published an article about VENDIA marine plank. Chairman of the
Wooden Boatbuilders Trade Association, Nick Newland contacted us to make this
article about the new interesting product for wooden boatbuilding. In this
article Nick compares the differences between VENDIA marine plank and
traditional rotary cut plywood and also tells his own opinions about this new
marine plank.
Among the
others, Nick also highlights first the difference in appearance between VENDIA
marine plank and traditional rotary cut plywood; VENDIA looks like the best
“clear and better” softwood with an attractive knot-free grain. There is also
difference in the number of crosswise veneers. Every other veneer is crosswise
in the traditional plywood whereas 9 mm VENDIA consists of only two crosswise
veneers. This structure gives the plank more bendability across the grain, Nick
writes. He also sees VENDIA’s thick face veneers as an important feature of the
marine plank. Thickness of the face veneer is 1.5 mm whereas the thickness of
the face veneer in traditional rotary cut plywood is often 1 mm or sometimes
even less.
Nick sees
VENDIA marine plank as an interesting new product for wooden boatbuilding and
he believes that it could produce a fine light boat which would look wonderful finished
bright.

First motorboat made of VENDIA
In early August we introduced a wooden boat made by Boatyard Ruotsalainen from
Nurmes, Finland. In late summer Ruotsalainen also built a motorboat of 9 mm VENDIA
marine plank. Therefore, VENDIA is also very suitable for building a wooden
motorboat.
Boatbuilder
Ruotsalainen made his first test runs with this motorboat on 4th August in
Pielinen, Finland.
The result
is as beautiful as what is used to see in rowing boats made of VENDIA.

Launching the first boat
The first boat made of VENDIA marine plank was built at the Ingman College of Crafts and
Design in January 2014. The Venla-boat was launched for the first time on
August 6th, 2014 in Kuopio, Finland. Paul Hämäläinen, the owner of
the new boat was one of the participants. He is also boatbuilder and has
finished the surface of the boat. Ilmo Koivisto,
builder of this first boat and other interested craftsmen were also present.
They all
were excited to test the first boat made of VENDIA marine plank. The
participants praised the model of the boat and the lightness of rowing.

Let us introduce the VENDIA manufacturing path
Raw
material used in VENDIA marine plank is butt logs from old grown Finnish pine.
A good quality raw material is the most important part of VENDIA. Whereas ideal
soil, clean air, clear water and slow growth are the key factors of high
quality raw material.
A good
quality raw material and sliced veneers make VENDIA beautiful and durable.
2. HARVESTING
Since the
high quality raw material is the key factor of VENDIA, is careful harvesting
and log sorting an important step in VENDIA manufacturing path. The wood is good quality and sturdy butt logs
from PEFC certified forests.
3. MANUFACTURING
We have
modern production line, professional personnel and the desire to produce the
best product to boatbuilders. Producing a good product for wooden boatbuilding
includes many stages until finished product is delivered to customers. The
first step is log debarking and 72 hours cooking in 90 degrees (194 °F).
Then the logs are sliced into veneers and dried. After that the veneers are
clipped and spliced into
its’ shape. After that the veneers are glued and pressed, rib sawed, cut and
sanded into its’ final shape. Final step is quality control and packing. Now
VENDIA marine plank is ready to be send to customers.

Experiences of the boatbuilder
Boatyard Ruotsalainen from Nurmes has built wooden boats of VENDIA
marine plank among the first boatbuilders in Finland. Ruotsalainen has built
wooden boats over 30 years, so he was very interested in this new type of
marine plank and he also saw it as a welcome novelty in addition to traditional
plywood. Now Ruotsalainen has built two boats of VENDIA marine plank and his
experiences have been great. Also his customers have liked the end result and
especially they have been taken to the appearance of the marine plank.

Fitting of the first plank. |
At first glance Ruotsalainen took notice of beautiful and knot-free
surface of the marine plank. Also the surface is softer than in birch plywood
but tougher than in conifer plywood, compares Ruotsalainen. Raw material used
in VENDIA is butt logs from old grown pine. A good quality raw material and
sliced veneers make VENDIA beautiful and durable.

Doing a clinker is similar than working with solid wood. It demands bit accuracy because of the colourless glue. Accuracy is needed when shaving
but the neat and beautiful end result will reward both the boatbuilder and the
customer.
According to Ruotsalainen’s experiences finding a good quality material
for the ribs have been difficult, so he tried out VENDIA also for the ribs. 12
mm VENDIA is suitable for the ribs but he rather recommends 10,5 mm thick
VENDIA only made of lengthwise veneers and lightened from the corners. Rib
made of only lengthwise veneers was assertive and springy and it bent smoothly.
In VENDIA marine plank crosswise veneers have been designed to prevent cracking
but in this case there is no need to worry about cracking because the ribs are
so narrow. Ruotsalainen also tried out making the keel and bow using 3 mm plank
of sliced pine veneers. Making the keel and bow of sliced veneers succeeded
well, says Ruotsalainen.
According to Ruotsalainen, wooden boats made of pine have always been
long-lived, so he predicts long life and durability also for boats made of
VENDIA marine plank.
