Haul-Out, Bottom-Wash, Zinc Replacement
Sno' Dog on the TraveLift at Great Bay Marina (how could you guess?) for a quick bottom wash & zinc check
Bare Bottom!
From this angle it's pretty clear why the PDQ is such an efficient powercat.  The only part of the boat that touches the water are those two long canoe-like hulls.  The guy who pressure-washed her botom remarked that it was the quickest 34-footer he'd done in a long time - so little surface to clean!
New prop zincs and rudder zincs installed, now she's ready to go back in the water
We replaced both prop and rudder zincs.  They were surprisingly worn out considering the boat has only been in the water since April - I guess it's been about 6 months.  It is, of course, their job to "sacrifice" themselves. Replacement is easy, it could actually be done under water if need be.

In the photo to the right, you can see the small keel which extends down about two inches below the propeller and thus affords pretty decent protection. To me, a shallow-draft boat without this protection makes no sense.  If you poke around long enough in shallow water, you will surely touch bottom.  With adequate prop protection, it's no big deal - you just back up and go somewhere else.  With exposed props, you ruin an $800 propeller or worse.
Here's the actual - computer generated - shape of the PDQ Hulls...
From the work of Malcolm Tennant and others, I gather this shape has evolved as the optimum for a displacement powercat.  It certainly works well for the PDQ 34.
I believe this was their original design - production models have a slightly more pronounced fin aft for greater propeller protection.
