Good choice on postponing the run: Scattered to widespread rain here w/SW to W winds today and tonite. Increasing to 15 Kts this evening.
I assume your talking about overnighting after your Cabbage Key lunch stop?
Either go out Boca Grande Pass and run offshore 'till Venice Inlet or stay inside and cruise the ICW to Venice; conditions will dictate that option.
If interested in overnighting in the Venice area options are as follows:
1.) Fisherman's Wharf Marina:
Nice floating docks; usual amenities.
The only complication is you have to have a 50-amp adapter for hookup there, if memory serves. (May be wrong on that..) Call ahead to verify..
Located roughly a mile South of Venice Inlet on the ICW/starboard side heading North.
2.) Crows Nest Marina:
Nice, old-timey place..been there forever,
Tidal currents due to the close proximity to Venice Inlet will keep you on your toes docking your 300. If strong currents exist, have a dockhand on the finger pier to help as you approach.
Located to Starboard as you enter the Inlet from the Gulf. If coming N inside, bend to port into a marked channel off the ICW as you see the "Party Island" ahead of you. (A popular local anchorage, and they'll be plenty of boats there over Labor Day Weekend.) Crows Nest is on your port side as you transit the offshoot channel there.
If you decide to motor on to Sarasota I would stay inside and run the ICW due to the tenuous nature of Big Sarasota Pass which I described in my previous post. Unless you run that Pass, there's no way to access the marinas there unless you go all the way to Tampa Bay and at that point, you might as well go on to St Pete.
During your inside run to Sarasota, you'll have to drop your antenna at the first drawbridge North of Venice Inlet. Depending on your clearance, you may need an opening.You'll certainly have to call for an opening at the Blackburn Point Swing Bridge. Other the slow manatee zones and the 25 MPH in-channel ICW speed limit, the trip is issue-free.
Sarasota Marinas:
1.) Marina Jack:
A popular spot since the 60's. Great floating docks, full service;amenities, eateries. Can't go wrong here.
Entrance channel to starboard just before you reach Ringling Causeway. Follow marked channel in.
2.) Longboat Key Moorings.
Very cool place, well-marked entrance to port. Go under Ringling, bend to starboard following the ICW around the shoaling at the New Pass Inlet junction.(See Chart)
Once in open Sarasota Bay eye the tall condo's to your NW and aim for them. You have generally deep water here. Pick up the marked channel into the basin.
This is a calm & quiet spot as opposed to the party atmosphere of Marina Jack. Your choice..either marina is great.
Being a Holiday weekend, I would make reservations at whatever marina you choose to stay at ahead of time.
