I found a columbia 36. It's a different layout than I've seen on many I've looked at. The main thing I'm worried about is the foreward bulkheads on the port side are partially cutout. You can see into the vberth. the bulkhead looks like it was cut in the same shape as the hull and about 4 inches left for structure? Is this a custom job or were some produced like this? any help would be great. Thanks
