Hi,Captain Krusty
My wife and i have just acquired a IP 29, 1991, this last fall in Montreal, We navigate on the Saint-Lawrence River and Gulf.
We have in common the same problem: changing the waste tank.The space available under the port front bench is quite small, 13 us gallons, or 49,2 litres. Next to this space is where is installed the Y valve seacock and pump.
Our first idea was to expand the volume by cutting the wood division and modified the set up or take it out. But, we choose to keep it untouched and to install a flexible Vetus waste tank of 55 litres or 14,5 litres, ain't much gain! It's not done yet, we've asked a boat technician to come and assert its feasibility or give us a better strategy, In a week or so, we'll have this confirmed and I'll try to get back to you.

P.S. I'm doing the exterior wood with Cetol Marine Natural Teak.
