Hi 'Brats!
Yesterday's trip from Harris Harbor (downtown Juneau) to Auke Bay via the Mendenhall Bar went fine but it had a challenging couple of moments. Here's the story.
The Mendenhall Bar is a six mile winding, shallow-water route through the flats from downtown Juneau, northward toward Auke Bay. It is well marked (I'm told the USCG repositions the buoys each Spring to keep up with the shifting shoals), but at its shallowest portion vessels only have 4' on a 14.5' tide(!).
Yesterday the high tide was at 1233 and 14.5', so theoretically we could make the passage if everything went as planned. At 1115 we were ready to be underway, and proceeded toward the day marker at the southern end of the passage. The day marker has a tide gauge that shows the depth at the shallowest portion of the bar. At 1130 the marker showed that the shallowest part was 2' ("...Hmmm, this IS going to be skinny!), but the tide was still one hour before High. Looking at the excellent tide data shown on the iPad's Navimatics program it appeared there was still about 16-18" of tide coming-in. We wanted to pass the shallow point at 12Noon

30 before HI) so if something went went wrong we'd still be on a rising tide*. We continued up the well marked channel at displacement speed until the depth showed five feet. At that point we wanted to kick it up on plane to scoot 'through the shallows. Motor down, tabs down, Power On, and Off We Went!
So there we were - speeding through the increasingly shallow areas at about 26mph; approaching the Shallow area. Looking ahead I saw what 'appeared to be a sandbar along the right shoreline, and slightly farther it "appeared" to completely block the channel. Oh $xxx !! Earlier, we had observed some tan-scummy stuff floating here and there along the way, but this time it looked EXACTLY like a solid sand spit completely blocking the channel. Quick thinking time. We reasoned that it "had" to be floating scum versus a sandbar, but moved to where it appeared somewhat narrower - at least if we ran aground it would be in narrow part. Swell ... meanwhile Mary was bracing for a high speed Impact, and claims she saw her Life passing before her eyes.
...and in a moment it was over!
What appeared to be a sandbar WAS only floating scum and we were Through, but it provided some exciting moments.
We proceeded to Auke Bay, fueled, and were lucky to find a spot in the Very busy harbor. There is a opening tomorrow for commercial fishermen in Lynn Canal, and Auke Bay is full of vessels who've prepositioned themselves for moving to the fishing grounds. Interesting; but very busy. This was probably the best day ever. Sunny and warm - we were even wearing shorts! It sort of felt like Florida with Mountains & Eagles.
So it's Saturday morning, and we're about to try the Juneau bus system and make a grocery run to Walmart.
Life isn't Good; it's GREAT!
Best,
Casey&Mary
* A few days ago some Juneau residents told us about an earlier grounding on what locals call the Mendenhall Bar of Shame. Evidently a visiting boater aboard a larger vessel was attempting to navigate the Mendenhall and received a call from one of the many houses along the waterway. When advised that he was probably too large for this area, and Certainly too large for the tide at that time, he replied that he was the Commodore of his yacht club at home was well versed in this sort of passage. The shoreline resident simply responded with - OK ... good Luck (and probably called some of his neighbors to watch what was going to happen). Shortly thereafter the vessel went aground on a falling tide. To make it worse, evidently it was at the time of the month(or season) when subsequent tides were getting smaller, not larger. The end result was the vessel was aground for a MONTH before he could get a tide sufficient to refloat his boat. ...but presumably he had a free place to stay for the month. Fun story whether true or not, but we had no reason to think it was just a Mendenhall yarn.
