Mike,

I'll attempt to answer you questions below. If you have any more, please email them to me.

:HDPE and polyethylene

I've never used Polyethylene, so I don't know anything about it. Eric
mentioned it in his earlier post.

:if you decide not to use double sided tape to hold the pvc temporarily in place, what would you use.

I will probably use a little double sided tape on the keel only next time,
to keep the skin lined up. The temporary shock cord will pull the skin tight
and keep it in place at the gunwales. I used a combination of the two this
time, and feel the shock cord holds the skin tighter during deck attachment.

: but do you glue the pvc or use heat, and is the sheer an

: overlapping or butt seam w/ overlapping pvc strip.

Use H-66 Vinyl cement. First, clean the surfaces to be glued with MEK,
let dry completely, and apply 2-3 coats of H-66 thinned about 25%.
Allow each glue coat to dry completely, ( apply heat if desired), overnight
is preferred, and overlay the surfaces to be glued, and then "Heat Activate"
the dried glue with a heat gun and use pressure to connect. Allowing the glue
to be dry completely gives you freedom to get things lined up before final
adhesion. You can however, let the last coat dry to the touch only before
connecting the two parts.

The same process is used on the Velcro to PVC connection, with the MEK / H-66
having superior adhesion to that provided by the Velcro alone.

The deck overlaps the hull at the gunwale 3/4" and is glued. You could also
butt it, and use a strip of PVC glued in place. More work however.

Don't know if there is a paint that will stick to PVC.

: what colours can you get, can it be painted? how much : does the

single weigh dry?

Mine include Lt blue, white, black, red, and yellow. But there are many
more, such as dark blue, various browns, green, orange, etc.

The single weighs 25 lbs dry.

I can't answer your other questions as I haven't tried your ideas myself.

: could you show a few more pics? like the deck seam, the coaming/skin

: connection, etc etc.

Yes, I will send several pics to your email address

Thanks for you comments,

Tom
