Cruising speed

7knts is quite fast enough! 10 at the most. /forums/images/graemlins/grin.gif

Aye, quite right. /forums/images/graemlins/smile.gif I was out this afternoon and even though the wind had died down it was just not pleasant doing much more than 10kn. Even the pilot launch had dropped down from his stock speed of 22kn, albeit to around 21.5 /forums/images/graemlins/laugh.gif
 
i tend to go more of my rev counters and tend to stick round 3000rpm with kad 43s that gives me a cruising speed of 23 knots,only now and again do i run over 30 knots to give the engine a bit more work for 5 minutes or so, but it has to be calm to acheive this as the last thing i would want to do is cause the hull to slam.but if you were to do 20 knots it is easy to work out your etas has you are covering 1nm every 3 minutes which is a easy sum to work with
 
To find out if you are going too quick, tell the skipper to get down in the galley and make tea, I will guarantee a call for reduction in speed will be forthcoming.
 
16-20kt suits us. Most of the time @ 16kt as she's ultra quiet, comfy ride, and fast enough to cover 100-150m per pay, and only 10gph, but mainly cause it's the trip we enjoy, no mad rush, time to relax, wander around the boat, eat, chat, relax, etc. Flat out it too much like work!
 
The responses to this post explain a lot. I have been managing a typical 22kts this year, and was feeling a bit dissapointed thinking everyone else was typically doing 27 -30kts.

However at 22kts we cant really go up front, but coming back into Chichester one sunny weekend doing about 24 kts a big blue thing shot past much faster than us and their SWMBO was posing on the coachroof, and seemed quite comfortable! I guess their boat was about 40ft. our is 32ft.

I would like it to be a bit more comfortable at higher speeds. guess I need another 8ft. /forums/images/graemlins/frown.gif

sounds like you are a little under propped. I get about 28/29 knots at 3000 rpm. Ok, my boat might be a little lighter, but she still weighs in at over 6 tonnes. Do you know what your props are?
 
Fascinating thread. As a raggie I always assumed the big benefit of a mobo was that you could go so much further in a day and therefore have bigger cruising grounds. I typically get about 7 knots and do sometimes sail through the night so 150 miles in a day is feasible for me.
 
As a Raggie 1) you have unlimited range 2) more comfortable in a decent sea 3) safer in a blow 4) have a more relaxing pace of cruising, BUT 5) need much more time. If I had the time I would have a rag and pole, not a mobo. When I retire fully it will either be a rag and stick, or a long range trawler yacht (eg Nordhavn)
 
Well its only my first year, I did find one advantage of speed. I booked my summer holiday (unknowingly ) for Cowes week, tried to get a berth but none available, but was able to just pop back to the mainland. It was no problem, but wouldn't have fancied another couple of hours to Gosport, it was late and I was ready for dinner /forums/images/graemlins/grin.gif
 
It makes far more sence to go off rev counters, as speed depends on bottom condition and other factors.

These days I choose about 3400 revs and leave the boat to potter along at whatever. Quite amazing really as I've seen 12 knots and 25 knots on the same revs.

Mind, rev counters lie through there teeth. /forums/images/graemlins/confused.gif
 
the ones fitted to the boat since new, but mine weighs over 9 tons loaded with fuel and water and can still manage 33 knots at full revs, but off course i only do that for a few minutees to give it a bit extra work. i think the boat empty weighs in at over 8 ton empty. but that extra weight helps if i get caught in the rough stuff and my cousin with his f 33 follows in my wake as it is a lot lighter boat so he likes me to flatten it for him. although my fuel bill is a little bit more than his.

So that's why an item on Sunday's Agenda (Chi Fed AGM) is what to do about boats doing just that.

If we end up with CCTV on the Bar Beacon you'll have some explaining to do!!

You hit the nail on the head ref our boating, Time is the biggest factor for us, if I were retired I would proberbly have a slower more economical motor sailer.
I only take 2 or max 3 weeks of a year, and I want to get someware reasonbly quick, then potter about and relax and enjoy the holiday.

I assumed coming into Chich meant somewhere between Winner and Chich bar beacon, most larger boats slow down 1/4 nm off the Bar beacon as a courtesy.

Of course there are incidents of craft tacking out against the current and wind which then force an increased speed in order to give way to the clowns.

As the Harbour limit starts 1/2 mile past Bar Beacon what do you feel a CCTV would show ?
Shops have footage of till operators taking money from the till and putting it in their pockets, the till operator is logged on and signed into the till but the CPS will not prosecute due to lack of evidence !
