Catamaran Cruising

Couple of picture  of where I put the exhaust and the controller.  Was on the boat during storm Ciara . So didn't go into locker to take pics .
My welded up double exhaust is not the neatest . The only 316 I had was some 2 in tube so I cut a piece and flattened after slitting the wall and then cut another piece to make the large pipe and a second cutting a peice out to make the 1 inch centre pipe .I had to angle it a 30 ish degrees to get it to the centre of the cockpit combeing  . Inside the  pipe rises up to give a 6 inch swan neck to help stop ingress but we rarely get much heavy water in the side deck  but I have started a small venturi removable chimney to prevent  back air pressure .
If not in use,  a cork prevents ingress . We can and haveused the heater  at sea
