We normally never take our boat south but we are taking friends who've never been there to Fisherman's Bay on Lopez in May. The other thread about the Swinomish Channel promted me to ask about the entrance to Fisherman's Bay.
We've been in there once in the GB, about six years ago, and both entering and departing were on a fairly high and rising tide. But this time we'll be transiting in and out at or near low tide, which on the days in question are -1.4 and -0.7 respectively.
Not long after acquiring our GB we measured the distance from the bottom of the keel to the bottom of the bootstripe when the boat was blocked in the yard. Loaded, the waterline is an inch or so below the bottom of the bootstripe. The draft of the boat is four feet give or take an inch or so. Hard to believe with a 30,000 pound boat, but the tape measure don't lie.
The low water depth in the narrow entrance channel according to the Navimatics chart I have on this iPad is 8 feet in the narrowest part of the channel, and 9 feet out toward the lower end of Upright Channel.
So at a -1.4 tide we should have a couple of feet of of clearance in the shallowest part of the channel. That's if the numbers are correct.
Anyone here been into Fisherman's Bay lately, and do you know if the channel depth has remained more or less the same over the last few years? Or has it shoaled up some?
We can time our arrival and departure an hour or two after low water which will put us on a rising tide as we go through. We'll probably do that to be safe, but I'm curious what other people have observed about the channel lately.
