Thanks so much, Guys
Both your postings were exactly the kind of real-world experience I was seeking. I had a slip neighbor last year with a Jeanneau 40 deck saloon with similar draft to my H36. He said the Annisquam route was no big deal at all for him, but after looking at the charts (and their soundings dates) I'm a little apprehensive. I'll take rough weather with sea room over calm mud flats any day. It looks to me like the ebb and flood currents under the Blynman Bridge are similar to the Merrimac, but the Canal is quite a bit narrower.I've made reservations at Cape Ann Marina for Monday night (down) and Thursday night (return), to accommodate the Admiral's (and our old dog's) limited sea-time tolerance.(We'll be at Hawthorne Cove Marina in Salem on Tuesday and Wednesday nights. Chuck, you're most welcome to look over Persephone's various mods.)However, after your inputs, I'm seriously considering going around Cape Ann and under the Blynman Bridge to the Cape Ann Marina. The forecast is for W'lies at 10-15, gusting to 20. In such conditions I can go 2-reefed at hull speed (or 3-reefed almost as fast if the Admiral insists on 10 degree heel angles)I've often done a quick daysail down to Halibut Point and back. I can usually get to Halibut Point from the MR sea buoy in 2 hours with any decent winds. If I went around, should I budget another two hours from Halibut Point to the Glocester side of the Blynman Bridge? Ot would it be more?The dockmaster at Cape Ann Marina, Peter, recommended being at his entrance with at least half tide, which would mean being through the Blynman Canal by 1330, or 1400 at the latest.To make it through the Annisquam, I also need to have half-tide or better, which dictates a fairly early cast-off at my up-river slip. If the Cape circumnavigation route took 4 hours, that'd mean an 0900 cast-off, counting the time to get down the river and over the bar.I realize this posting is a stream-of-consciousness, rather than a definitive statement, but I'd appreciate any further commentary you'd have time to add.Fair Winds,Al
