boat damaged by bobbing pilings

[dory24]

be careful out there folks, just had my prop and maybe my rudder torn off a little bit past the mile marker out of the Manasquan this morning. hit the submerged crapola at about 25 mph, hit hard and the back of the boat just about cleared the water. after making sure I wasn't taking on water, and thank god I wasn't, I looked back at what seemed to be a full section of bulkhead or boardwalk. 2 pilings connected by 2 20 foot or so 2x10's. the pilings where only visable at the crest of a swell, besides that they where submerged. will be pulling the boat this afternoon to check for the full amount of damage.
