made up of several sheets of veneer or plies.Itundergoes the method of pressingalong,affixed and grains
getting into multipledirections.
Cheap plywood may be a top quality wooded sheet that has resistanceto:
o cracking
o breaking

o shrinkage
In boat-building,it's notpractical to discuss every type of lumber. There are specific woods common in every
country nevertheless imported lumbers may also befound.
The common rule:
Any lumber within the localethatbecomes successful in boat-makingwill beapplied.
Although there are some characteristicsof the wood that require to be considered like:
o weight
o strength
o decay resistance
Look for wood which will match these requirements. If the boat designer needs a light-weight lumber likeSitka
spruce, don't providehim white oak. It’d double the load of Sitka spruce.Whi te oak weighs heavier. Weight
can have an effect on the performance of the boat. You’ll be ableto usewoods of comparableweight and
strength as substitute.They need to also proveto be successful for boatcreating.
In shoppingfor Lumber
Determine 1stthe specified thickness of wood material to be used. The designer should note within the plan
or material listingtheparticular lumber thickness.The thickness of the lumber is typically theprimary
dimension.It’s referred to as the sided dimension.For usefulness,the designer should providespecific
standard for lumberyard dimensions like:
o 1" material refer to four quarters or
o 1" material to 1" net

2. When askingfor a quotation, note these to your lumber provider.You be ableto conjointly purchase only 1 big

additional allowance.
To re-sawthis board,you may want a power saw. It will bea:
o table sawor
o radial armsaw
In choosingLumber
Select the particular board to use when decidingon the kind of lumber. Wide width is generally preferred.
Long length is advantageous.Once the plan wants a member 20' long however the offered is only 12',it will be
formed by:
o Scarf jointor
o Butt joint
The builder should check his plan to assurethat the jointbe found at a strategic location.
Example:
By usinga butt jointand butt lock, a 2 10' length will beused to make 20' member. It’s probablethat the joint
be found within the location of the hull.It’s stern curvaturewhich will createthe jointmore difficultto create.
On the oppositehand, 12' and 8' length makes 20' member conjointly.Itmight be manipulated to find the
jointoutsidecurvature. It’ll alter the joint.
To selectacceptablematerial,the builder should check all decisionsagainstthearrange. The lumber for boat
creatingproject should be seasoned.It suggests that removing wet from the wood. It’s done to boost its
purpose.

2. Kiln dryingmethod
o It is appropriateif done properly
o It will leavea lotof wet within the wood if rushed or
o It removed too much wet within the wood that creates it brittleif cooked

3. If it's cooked, the wood cannotbe appropriatefor boat building.And, if the wood contai ns much wet when
seasoning,the wood can shrink or split.If possible,chooseboards thathave vertical grain conjointly referred
to as edge grain or riftsawn stock. These boards expand and contractwhilenot an excessiveamount of
distortion.
Look for lumber defects
Defects should be checked. Individualsconfused with blemish as defects. Blemish affects only the looks
however not the serviceit provides.A defect is an irregularity on the wood which will havean effect on
strength. It’s generally limited to a certain area only. It will becut away.
Two kinds of defects:
o Those caused by seasoning
o Those caused by the approach of tree growth
Seasoningdefects are caused by removing wet and shrinkage.Common seasoningdefects includechecki ng
and warping. Natural defects caused by growth depend on the species of lumber.
Common natural defects are:
o knots
o cross-grain in wood
o shake
o decay and rot
