Yotties...a moan

Re: Hmm...One way to assess your wake is ......

Oh dear! Just cos you cant see it doesn't mean its not there. At displacement speed you "pushing" water out of the way. The boats travelling "in" the water displaceing the water as it moves. That water has to be displaced somewhere, so you get a wave. Sit and watch other 30 foot cruisers ploughing through the water at 8 knots. Once planning the boat is travelling "over" the water.

To get the full affect of your wake, get someone to plough past you while your in the dinghy. I think you'll appreciate why the raggie waved at you in such a friendly manner!

Re: Hmm...One way to assess your wake is ......

I not suggesting that it's not there! ...........What I am trying to say is my 'perceptable' wake...IE that that you can actually see onboard.....is it any smaller?????
Forget about the bow wave for the moment.....I can't see that for sure.

If it's the case that my wake IS 'perceptably' smaller than it would give the 'impression' to those on board at least.....that we are not trailing a big wake! When in fact we may well be overall! It's a point worth considering and I shall investigate further.

I think this has gone just about as far as it can now............until the next time....

I have read this post with interest and I find myself both agreeing and disagreeing with MrPlastic.

I am sure that there are good and bad skippers both amongst power boaters and raggies - however I do find that on balance I have more problems with raggies who just do not comply with the rules of the road - leaving too little water depth for a port to port passing etc. Without exception all my experiences have occurrred when the offending raggie was under power and not sailing. I always leave ooddles of room when they are sailing and so have never had a problem.

On the other hand just because a speed limit exists it does not mean that you have a right to proceed at that speed without regard to other users.

At the end of the day, I go boating to escape all the stress not gain new stress so I try very hard not to lose my cool.

I have watched very rude power boaters making raggies rightly very angry - if we can all just learn to be a bit more polite on the water, it can only help us enjoy our sport more.

Displacement Speed

If I remember correctly the formula for calculating the maximum displacement speed is 1.34 times the square root of the waterline length in feet. So for a 30 foot boat with a waterline length of 24-25 feet, means once you are going faster than 6.5 kts you are trying to climb onto the plane and creating a much bigger wash than you think. You need to be be doing 5kts or less untl you can speed up to get on the plane. 8kts might be fine for a boat with a 36 foot waterline length i.e 45 footer? Then I still doubt it for the modern fly-bridge boat.

Bet you're sorry you started this mrplastic. Best write it all off to your confessed lack of experience and try to do better next time.
Still there is some good news. Although you were <font color=blue>'at least 100 yards away'</font color=blue> you apparently heard them <font color=blue>'telling you that you were in an 8 knot limit'</font color=blue> All this above the noise of your engines?. Wish my hearing was that bloody good or perhaps your judgement on distances is even worse than your judgement on wake. Methinks thou dost protest too much!!!

Must have good eyesight too. If it is any help I can confirm that on our boat travelling at 8 knots with the drive at -2 and tabs down the wake is noticeably lower than with the drive at +2 and tabs up. Don't know why. As previously mentioned there is also a significant difference in wake size at a given gps speed depending on whether we are going against or with the current/tide. Our wake size at 6 knts is only about 20% of that at 8 knts.
Doesn't justify your friend's "verbals" though.

Soloution to it all,,,,,,BUY A HOVERCRAFT cos' you'll make no wake and give the yachties some wind/forums/images/icons/laugh.gif

Speed doesn\'t matter...

... within reason of course!

It is the wake that is all-important. When in my tender, the wake I produce doing 6-8 knts is far worse than when it's on the plane doing 10 kts! The local harbour tug produces an incredible amount of wake when only doing (estimated) 5-6 kts, but technically he's within the 8kt limit. Far better to have signs (which I have seen) saying proceed at "No-wake" speeds.

I must stress that I in no way condone PWCs travelling at 20kts through moorings and anchorages, however little wake they produce at this speed!

Cheers,

Jerry

Re: I can\'t see...

What all the fuss is about...

You wouldn't paint your car by the side of the road would you. You'd take it somewhere sheltered and out of the way.

Like you wouldn't go out in a boat and not expect to rock about a bit...would you?

When the tugs,ships,ferries,disco boats and PLA vessels come past our moorings at Thurrock (not Basildon, thats where me scrap yard is) we get rocked about a lot, theres no speed limit, but its still not the end of the world and wouldn't cause me to burst into a sweary tantrum and spit me dummy out.

Some people just moan for the sake of it.

those in Chichester harbour will know this years harbour master focus is wash, less so speed- as long as youre under 8knts. So those of us from there are perhaps more aware than mrplastic that 8knts doesn t mean youre in the right.However, it appears that he thought his wash was acceptable, and some one sitting in a beer crate disagreed. Mrplastic quite possibly made more wake than he realised, and will now be more careful. But doesnt the man in the beer crate have to accept some of the consequences of doing so ... or is that a bit too grown up in todays political doctrines.

The guy that got me tho spent all last wekend sailing a miracle dingy up and down the marina channel.
Given 1. that there was bugger all wind in the sheltered marina and more outside
and 2. its a bl**dy narrow channel at the best of times
Does the panel think it was reasonable to try running him down and claiming ' restricted ability to manoevre / constrained by depth'??

Hi . I am impressed by the consideration shown to others on this thread.I thought you would like to know even a raggies get it wrong.In Holland a couple of weeks ago i was "proceeding at speed"(i never race!) along a canel to catch an open bridge .6kn in a 6kn limit.On passing the bridge(i couldnt see them from the other side) a number of boats were in "Boxes" on my port side.Even though i had backed off the engine i was probly still doing 5kn as she takes a while to slow down when a guy on one of the boats gave a rant at which i put her in neutral until i was doing 2/3kn as intended.
As said above not all sailors (both raggie and MBers) are t****rs , but then again most of us are human and do make mistakes.

That was a well constructed and thoughtful reply. You are correct, yes I did consider my wash to be acceptable, however I will watch my wash from now. We never stop learning and I am always open to constructive critisism. I'll always accept that people may think I'm wrong...but they must prove their case. Someone arguing for the sake of it and quoting meaningless parallels does nothing for me except prove beyond all doubt that I am more likely to be in the right than they are. None of us knowingly make mistakes, to do that would suggest that we diliberately get it wrong......I've never done that and I doubt many of the contributers to this site have either. It was suggested in this post that I probably regretted starting this one.......not at all. I think we may have all learned something from it. I know I have.

Re: Hmm...One way to assess your wake is ......

I agree with this, but unfortunately I am incapable of decorating my agreement like a fairground ride! Very jolly though.

Fact of the matter is that an 8knot limit is already highish, and going past moored boats pulling a sizeable wake (especialy when someone is obviously working on their boat) seems a bit inconsiderate

Re: Hmm...One way to assess your wake is ......

Do you have to flash those lights? They make me feel funny/forums/images/icons/smile.gif.
This side o' t' pond, they use "No Wake", ie what it says and usually <1000rpm, and "Minimum Wake" which is just below the speed at which the bow begins to rise. Speeds are rarely mentioned 'cept in ICW, when it might say max 25mph in places. Seems to make more sense than 8mph when what is meant is minimum wake (no wake being around 5mph or less).

Yet again when someone moans about a different type of 'water' user that 'water' user is never going to see the point of view from the other person, if he/she does they'll never admit to it! I no this from living with a yottie (she'll kill me for calling her that) and being a powerboater myself. I understand that yotties don't like big wakes, but if people like Ellen McArther can cope in force 11 seas for days on end im sure a yottie can cope with going over a wash for 30 seconds.

Had an incident couple of weeks ago in Cowes week. First time i've ever been around the IOW in Cowes week and it frighted me so much. I woke up around Hayling Island and looked up and all i could see was a wall of yachts. I said to my skip "we're going round that right" and he replyed "nope we've gotta go through there is no end to go round" My fingers would break off if i told you every experience we had whilst going through but one of them was quite interesting. A yacht (very small wooden day yacht) screamed at us to slow down, which we did - coming off of the plane. 30 seconds later he screamed for us to speed up because our wake was bigger off the plane than on. I was gob smacked - a yottie shouting for us to speed up!

I would just like to add in reply to some of the posts. Firstly if someone is using the galley in any way whilst at sea in crowded or rough waters then ive got no sympathy for the consequences. My Dad has NEVER let any of us boil a kettle or get a knife out to butter bread for a sandwich whilst at sea - if we had it was like we had committed a crime. Half an hour before we set off Mum makes shed loads of sarnies and flasks of Tea and Coffee.

Secondly i dont think you can relate revs to speed coz every boat will be different. Our 38 footer at 2500rpm does about 20 odd knots and we are nowhere near on the plane at 8 knots. It can be argued that marinas should have a wash limit rather than a speed limit, but as it is its a speed limit and if a boat is doing the limit or below then maybe its inconciderate if the wash is big but its legal!
