Sig Marine can supply you with a stainless steel thru-deck fitting for your pipe
installation. The thru-deck fitting includes a stainless steel dress ring for the interior of
the cabin and a rubber (neoprene) gasket easy mounting. Depending on the contour or the
angle of the cabin top, you may need to make a hardwood spacer block. One surface of
the block would be a level plane to mate to the deck cap. The other would match the
angle or contour of the cabin top. A hole through the center of the block would be 2
inches greater in diameter than the flue pipe.
