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. =20

Subject: [Rhodes22-list] V-berth flotation
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
