Alright - some more questions just to verify my thinking.  The keel lift runs through that block, back up through one of the two blocks on the crane, then back down and terminates on the shackle just aft of the block correct?  I assume the forward and aft-most bolts are locking the keel in the down position?  And then the loose metal plate and shackle sitting there are for the single-point lifting strap that gets attached to the aft lock-down bolt when the keel is in the raised position?  Finally, what is the round plug on the forward port side of the keel - was there a kelp cutter at some point?

Yours is definitely setup different... First, ditch that block and replace with a new high load alloy sheave bolted in for the main lifting point.

Don't use a lashed block or it could get ugly.

Mine runs from crane, thru sheave and back up to anchor point on crane. Not sure what those tabs are for. Most likely for strap as you mention.

There should be attachment points for this at the rear base of keel trunk and forward floor of cockpit. If not, you'll have to find where those tabs bolt to.

The plug on the Port side is exactly that, a plug. Remove and push in the kelp cutting device (see photo). When done, reinstall plug. Takes about 8 sec.

Also works well for underwater bluetooth camera on your phone if you make an acrylic plug. Check for kelp anytime this way.

Mine is 4:1 and terminates at crane end-cap. Sorry no photo. The extra purchase is good if you use a cordless driver instead of the winch which can be slow.

Your crane is lacking the end-cap where pad-eye would be. 

Some boats are also rigged 2:1 like above. Faster to winch up but more muscle required.

You should also have a worm drive winch that holds everything in place when under tension.

All in all a fast looking ride and good choice for the bay I'm sure! I'm no expert but in the interest of debate how are they getting away with no main bulkhead? That's suspicious to me and given the chop we sail in on the Chesapeake a stiffer boat is worth a little bit of weight.

It's not a bulkhead. Nothing structural in fact. Merely a lightweight privacy partition for the head and v-berth held in place by a few screws. Some boats including mine have removed them for more space/access to fore-peak and sail stowage. Heads and holding tanks removed as well. Makes the boat much more roomy inside accessing usable space.

That's interesting - we were debating what to do about that as the previous owner had the bulkhead but never installed it.  I was chatting with Tim Kernan a couple years ago about his boat (ex. Comanche, Exigent, etc) and he mentioned that he had added carbon bulkheads and framing which he thought made a big difference in performance.  

 
Carbon Wedge Tabs under key deck areas have been added. Same on chain plate frame. This is a grid boat so no primary bulkheads. I know the later boats were a bit lighter (and more flexi) especially Exigent which was the lightest and most oil canny of the bunch. Also the fastest. Perhaps a bulkhead was added but I’m unaware of it and never seen. The first 2 boats were built by Morelli Melvin when they still had a shop so no issues with these although they are probably about 300-450 lbs heavier overall. This also includes inboard saildrive and the 2’ stern treatment a few of these got including mine. Yours should be a kick to sail as it’s basically stripped of everything. Curious what it weighs in at. Have fun!

Yeah - I have to imagine it's quite light - there's basically nothing to it besides the base structure and electronics.  Exigent is actually sailing out near me now - we've been chatting with the new owner a little.  I'd like to get a look at it sometime.  So is your boat the former Pacific High?  

Yes, the listing does mention the runners.  I'll have to look for them.  The boat is currently 4 hours away so that'll have to wait a week or two.

Looks nice.  Hope we can get ours looking that good eventually.  

It'll be interesting to see what rating we end up with.  Exigent (Now Victorine) rates 75 on the bay.  I would think we should be right around there...

 
Single Rating? That seems generous but I’m not familiar with East Coast PHRF. I’m lower at 72 buoy and I’m carrying the smaller jib and inboard. Rating gets way lower for downwind events here. Hell- I think I owe the J88 time which seems absurd but whatever.

We have random course ratings too which are lower, but they aren’t commonly used that I’ve seen.  And I think J/88’s rate 87 here...
