[Rhodes22-list] adding flotation

[Roland.John]

Re peanuts - a lot of shippers are starting to use bio-degradeable peanuts for packing material.  They dissolve in water.  It's a good idea to test them before use as well.  J Roland

Hi Joe,
Just a caution from experience. I had gathered a lot of polyurethane packing
foam to put in my v-berth. Before I put it in I put some in water,good
thing, it made a good sponge. The kind of polyurethane foam that goes in
boats is closed cell, which means it don't absorb water, important for
floatation. I'm not sure about peanuts but be sure of what you put in. It
cost me around $150 to pour foam and it took away any guessing. If I should
ever need it, I figure I will have enough to worry about, besides if it the
floatation is the right stuff.

I was speaking with a boat builder in Stienhatchee, he primarily refurbishes
older commercial fishing boats and brings them up to custom specs.  On
flotation, he says if his client wants to save some money, he can mix in
styrofoam blocks and even those little packing peanuts. Then he pours the
foam over them.

I've never tried it.  But does anybody see a reason why this would not work?

Dear Todd,

Yeah, I wrote some of those e-mails.  As I recall, there was a lengthy
thread involving the V-berth & the floatation foam underneath.  I don't have
that e-mail anymore & it doesn't seem to come up on my searches of the
SailNet Archieves.  What is your question?

I recommended the 2-part pour in place polyurethane foam product.  Look on
page 56 of the 2002 Defender Marine Buyers Guide.  The product provides 4.8
cubic feet foam/gal of premix.  Defender will sell you as little as 1 qt (2
pts of Part A & B) or as much as 10 gal (5 gal of Part A & B) of premix.
Parts A & B are mixed together for 30 sec until the liquid turns milky.
Then, you rapidly pour the mixture into the void space to be filled.  The
mixture will expand & cure tack free in 1 minute, with final cure in 20
minutes.  To fill a large space, small batches can be poured right on top of
one another.  If a new batch of foam is poured on top of an old batch before
final cure, then the bond between the two batches will be undetectable.

Before tack free cure, the mixture will flow.  So, to do a V-berth, the area
would need to be sealed off so the liquid would not run down into the bilge.

This product is not real toxic, but I would still use a Tyvek suit, rubber
gloves, eye protection & as much ventillation as I could get flowing thru
the boat.

All,
     Recently I read about someone with a boat about the same year as mine
(1974) that did not contain, or it had been removed, the foam flotation
under the v-berth.  I can not remember where I was reading it or must have
deleted the e-mail without copying it to my files.
     Someone (I think it was Roger) posted a suggestion for expanding foam
to be used to fill this area.  Can anyone help with a suggestion?

Todd
