on launching a canoe: Part Two

on launching a canoe

Don't drag the canoe accross rocks sharp enough that you wouldn't put them in your mouth. Or any substance that is harder than the surface of the canoe.

Canoes are manufactured from a number of materials.  The durability can be graded and what follows is a list and breakdown of canoe compositions.

Plastic
The plastic canoe rates high on durability.  This canoe is resilient to rough treatment; plastic is tough and can be scraped and scoured without developing a leak.  Plastic is also easily repaired with plastic plugs and a low temperature torch.  On the other hand, the plastic canoe leaves a wake of microscopic plastic particles everytime she touches down.  Another problem is that plastic canoes have an unfavourable strength to weight ratio.  Compounding this is the necessity of reinforcement stays or beams, in some cases, to retain shape or load rating, owing to the low tensile strength.  Plastic is also prone to relaxation. Keep this canoe out of the sun if left strained.

Aluminum
Of the constituent particles of the earth, if analysis is limited to what is termed the crust, element thirteen is is the most common true metal. Aluminum is so common that it takes a ton of scrap to buy a jar of pretzels.  What does this mean to you?  The price of aluminum has no bearing on the value of an aluminum canoe it suffices to say.  In Montreal, aluminum canoes of excellent craft and gauge are had for nothing.  In Wisconsin, the value of aluminum canoes is inflated to such an extent that you can likely afford one with bullet holes and dents galore only.  The market for boats is unencumbered by realistics.  Whether this is good or bad is hard to say.  Aluminum, as a material for a canoe, is a good choice:  Aluminum can be repaired easily; is cool to the touch, has a naturally attractive luster, is of excellent strength to weight ratio (no mystery why the wright brothers salivate at the mere mention of), is in abundance.  Aluminum, from a cost to longevity perspective, is the material of choice with which to build a good canoe that will survive the eons.
