I am faced with the same problem. In addition, the scupper
tubes pass through the bullwarks of the deck and then over
through the topsides. They have developed cracks and are leaking
water into the inside. I am going to make new ones and glass them in
and am thinking of allowing them to protrude about an inch beyond
the topsides. Then fashion a rubber or vinyl boot that will slide over
and clamp in place. That way I can periodically replace them. No
worries about scraping them off while docking since they will flex.
The drip marks down the side of the boat are annoying and poking
more holes is not my first choice.

I tired of drip marks and stains down the hull topsides from scuppers.
I want to get a solution before I have the boat LP'd.

It seems that I either need to fill in the scuppers and put in
thru-deck scuppers that drain down to thru hulls in the bootstripe -
or put some kind of drip tube or drip lip - either permanent or
removable - into the existing scuppers so that drips would drop far
enough out from the boat to miss the topsides.

I'm concerned that permanent stiff ones like s/s tubes or whatever
might scrape people or poke inflatables while trying to board. Maybe
something flexible like clear silicone rubber sheets or tubes?

Seen any good ideas?
