By hatches, Catamoron means the bow locker openings, not the Bomar cabin
hatches. He also means PVC hose, like used in water systems, not rigid PVC pipe.
Yes, these lockers have a lip channel around them that the lid edges overlap, and the channel has a drain fitting with a hose leading to a thruhull. We have never had a problem with ours and any leaking here would just go into the sealed lockers and out the bottom drain hole - there is no way any water could get into the interior
of the boat through these.
The cockpit seats also have thruhulls in the designed lowpoints with hoses leading straight down to the bridgedeck drain thruhulls. One of these could reach the aft cabin if it was leaking, but the aft cabin walls are solid fiberglass
covered with polyolefin "monkey fur" - so there is nothing to destroy with water. At worse, the monkey fur will need to be cleaned, which is very simple and easy (you can bleach it without damage). Our newer model 40 has Trident reinforced water hose for the cockpit drains - I don't know what was used in the older 38's.
The jib is a camberspar. Whether one likes it or not is a personal preference. We love ours, and most who sail with one for a while tend to agree, as its benefits reveal themselves with use. The times we find ourselves wanting the ease of a roller furler
are far, far fewer than the times we find ourselves enjoying the self-tacking upwind or the perfectly shaped jib self-winged to windward when off the wind
The jib is, however, small - ~90%. This is fine for medium to heavy winds, but for very light winds we have a code 0 to fill that gap.
Hope this helps.
