Zoe 8 Posted November 24, 2019 Share Posted November 24, 2019 Hi guys Long time no see. I've had four children since I last posted properly and now they are now all sailing opti's! So a lot of time has gone by. After 10+ years of being boatless, I am lucky enough to be helping look after my father's Logan 33 which we have recently moved to Milford Marina. It draws just over 60cm - it's a gorgeous boat and we want to get out and use it more. I am trying to get a handle on the tides and depths at the entrance. Is there any simple answer as to the time either side of high tide we are going to be okay to get in and out? Or am I going to have to get my calculator out.... which has all sorts of possibilities for ways to go wrong. Advice appreciated! Zoe Quote Link to post Share on other sites
Black Panther 1,672 Posted November 24, 2019 Share Posted November 24, 2019 Hi zoe, good to see you are still alive. If you learn the rule of twelfths you can do it in your head using a tide table Quote Link to post Share on other sites
Zoe 8 Posted November 24, 2019 Author Share Posted November 24, 2019 Okay I have googled that, will have a go, thank you! Yes still alive. Very happy to be back in the boating world! Quote Link to post Share on other sites
Adrianp 123 Posted November 25, 2019 Share Posted November 25, 2019 In the Piedy with 1.4m draft, we used to plan on 2 hours before high tide and 1.5hrs after high. We touched a few times at the 2hr before high so seemed pretty accurate! Quote Link to post Share on other sites
Island Time 1,278 Posted November 25, 2019 Share Posted November 25, 2019 Hi zoe, good to see you are still alive. If you learn the rule of twelfths you can do it in your head using a tide table The rule of 12ths is the best tide aid I know of. Works everywhere, even when there are no tables. And accurate enough for practical use. I really cant understand why no-one teaches this on any of the courses I've done. (NZCG, RYA, etc) Quote Link to post Share on other sites
ex Elly 217 Posted November 25, 2019 Share Posted November 25, 2019 If you only draw 60cm, then you should fine any time above half tide.

wal 27 Posted November 25, 2019 Share Posted November 25, 2019 Four?!? Haven't you got a television? Nice to hear from you again Quote Link to post Share on other sites
Zoe 8 Posted November 25, 2019 Author Share Posted November 25, 2019 Thanks everyone, the 'any time above high tide' sounds like a good rule of thumb to me and my mathematically incapable brain. Wal, we have a TV and numerous iPads to keep them busy but weird thing is they want to be outside! Quote Link to post Share on other sites

Zoe 8 Posted November 26, 2019 Author Share Posted November 26, 2019 Half tide... I know what I meant... Quote Link to post Share on other sites
waikiore 438 Posted November 26, 2019 Share Posted November 26, 2019 Be Aware that the prevailing breeze at the entrance has a big bearing on Milford, half tide is not right as the sill moves depending on height not time. Quite often the sill will still be up then. If you damage the sill the Mariners will send you the bill. Please go for a good walk with the kids at dead low one day and you will be then armed with the knowledge. 1 Quote Link to post Share on other sites
