New Sailor learns more!
I just bought my first sail boat (after years of motoring) and just completed my first sailing course last week. Should've gotten 100% but learned some nice details. Thanks for the quiz, its a good learing tool.

The skills quizes will keep ya humble...!
I've yet to get 100% on a skills quiz, so I guess I've still got a lot to learn! However, I would have to disagree with the answer to question #1. While the answer given was technically correct, it seems quite imprudent to me to go under a bridge with only one foot of (supposed) clearance, especially on a rising tide. Doing so leaves you little (if any) room for error, and the results could be anything from embarassing to disasterous. One foot is cutting it too close for my tastes! Jeff

Finally!
I didn't think I'd ever get 10 out of 10, but today was the day. I am almost sorry as I really have gotten used to looking up 1 or more questions in the books and typically always find more new info than I was looking for... thus learning even more. Anyways, another great quiz. My only wish is they would come more often! Thanks Gary.

Gary, this was the best one yet!
And no, not because I only missed one. It was well rounded and fun. Good job. Now, your assigned task, should you choose to accept it, or not,, is to,,, top it.

Thanks again Gary
These quizzes are always fun and a great way to learn new things too. Thanks again for your time and effort in putting this one together. Peter H23 "Raven"

hey gary!
This is a good one. the only problem i had was with question one, the question asks what time you can clear the bridge, not what is the latest time you can clear the bridge! this is a great way to get us all thinking keep it up!

FUN QUIZ,,,,Don't agree with #1 answer!
Good show!!! keep this going,,,,tis fun. However, in guestion #1 you indicate; 1300 is the last chance to get under the bridge (with ONE FOOT clearenst). That is cutting it too close,,,,Let "Charly Super Powerboat" come ripping through about the time your mast gets directly under that bridge that IS one foot above your mast,,, and YOU could have a mast several feet shorter!! Give me the better clearance of the 1200 hour cushion! As for heeling my boat to MAKE clearance,,,WEEELLLLL,,that's how my boat got her name,,"TOO MUCH". It took me too mush time to find a boat this good, too much money to purchase her AND it would require TOO MUCH down time & money to repair her if damaged due to my inpatients. Better sail safe, just stay one more day, then sail with the next tide.

Great quiz - but #1?
Also always enjoy these - Fun to try and always learn from them. On question #1 though, you state the "mast" is 45' tall... I went on the assumption that there is a boat under that mast, with 4 or 5 feet of freeboard, and that boat would need 50 feet of clearance. I went with "no way." Thanks again, Gary, and keep 'em coming!

Agreed: Q1 correct answer was purely academic
I also chose incorrect answer, but on different ground. I feel one foot clearance is pushing it a little. Unless there are no waves, wind that may push water higher etc, etc...

Good Ole Question Number 1
First of all, thanks for your comments. We'll endeavor to keep making them better. Regards question number one, the purpose of the question was to test your knowledge of chart markings and tidal movement. The clearance on NOAA charts is shown as the clearance at mean higher high water. Conesequently when the tide is lower than that, the clearance is greater by the amount the tide is less than MHHW. The tide moves up (or down) generally according to the rule of twelfths--one twelfth the first hour after the tide change, an additional two twelfths the second hour, an additional three twelfths the third hour, an additional three twelfths the fourth hour, an additional two twelfths the fifth hour and a final one twelfth the sixth hour. Consequently in the question the tide has moved up by six twelfths or four feet by 1300. Since at 1000 the tide was down eight feet from MHHW, the clearance at that time was 50 feet or five feet above your mast. At 1300 the clearance was reduced by four feet down to 46 or one foot above your mast, still enough room to clear in theory. Me on my boat? I'm going through at low tide at 1000!! I hope this clarifies things. Gary Wyngarden S/V Wanderlust H37.5 P.S. In response to specific questions, mast height is generally referred to as the distance above waterline and the question also asks "by what time do you need to pass under the bridge..."

question 9 musings
GREAT QUIZ chart 1 page 43 item 11(if my old eyes are seeing correctly) shows an underlined number for uncovering rock i missed the underlined number in your answers. also what happens if your chart has soundings in meters

Getting better at these
Hey I am getting better at these, I got 7 right this time! I looked up the ones I got incorrect and definitley learned something new.

Reminds you of things you thought you forgot
It is a heck of a lot better to grapple with these situations in front of my PC than to evaluate the situations under the stress of multiple problems on the boat. We can't get too much of these challenging questions. They make us think and learn. Keep them coming!

Q.#1, facts need to be checked
Re: Chapmans, 62nd edition, page 335 "Normally, height datum is mean high water" not mean higher high water as stated in the quiz explanation. Just thought I'd mention it.

tidal bridge clearance - question #1
Yes, theoretically your answer is correct according to mathematical calculations using the rule of twelfths, an important concept for mariners to understand. However, a wise skipper would be "out of his mind" to wait until 1300 hrs... 1200 hrs or 2 hours after low water should be the max to insure a safe passage! The rule or twelfths teaches us to beware of that third hour before or after slack tide. IT'S A BAD QUESTION because of the choices 1200 & 1300. Perhaps 1100, 1230, 1400, might be better choices to insure a fair question. As a USCG licensed Master, I can say that...on a Coast Guard licensing exam, this question would be thrown out upon similar protest.

It is my understanding that the rule of twelfths..
