planning or displacement???

"He's talking utter crap."

Was that comment aimed at me?........Yes a lot depends on his likes and dislikes, and at the end of the day he will buy the boat that rings his bell. Sure enough if speed is at the top of his list, then a nice deep vee planing hull would suit him better.

I was expressing my views on the sea keeping abilities of the boats he mentioned, based on something like 20'000 sea miles in craft of all kinds, but hey, you are probably right, you being a proper old sea dog and expert in all things nautical. /forums/images/graemlins/grin.gif
 
Thanks guys for your advice, it would seem that it will be an ever ending debate on hull types, I suspect like so many things in life it is all about your own circumstanses and personal choices, It is however interesting to get varied points of view from people who have had plenty of experience of all types of hulls.

I have been thinking and looking for the last couple of years,I havent made my mind up about what sort of boat to go for as yet!


Please keep your thoughts and comments comming as they are ALL helpfull.

cheer for now /forums/images/graemlins/smirk.gif OAF
 
Well whatever you decide to do, I wish you the very best with it. The chances are that you are trying to come at this boat buying malarky using your head, but if you are anything like most of us, your heart will end up being in charge. Whatever any of us has to say on the matter, buy the boat that really rings your bell, because if you don't, I think you will spend a long time wishing you had! /forums/images/graemlins/smile.gif

You have and will, get all kinds of opinions expressed here in these forums, all of them valid in their way, but blatting about Lake Solent, and hopping from one marina to the next, is a whole different ball game to long distance cruising, off coastal areas that may not have any convenient bolt holes.

Oh bugger!......Does that mean I have now got to scoff some humble pie!??..........Damn! /forums/images/graemlins/grin.gif
 
Think it is important to decide what kind of boating you wish to do. Displacement means extended cruising time (by virtue of lower speeds). Planing means higher speeds when passagemaking so shorter times between two points, but noise levels will be higher. Semi displacement is somewhere in between!. Whatever hull you select it will be a comprimise but that is what you have with any boat you care to name. Before you buy anything have a sea trial and see whether you can live with your prospective boats foibles
 
Would be helpful if your "UK coastal " was a bit more defined and how definate your proposed final destination is.
Many rain soaked home based boaters see the mediterranean as some sort of nivarna,which is not bourne out by facts .There are many very experienced long term boaters on here who have boats down that way who can give you the hard facts regards the variable weather, difficulties arranging moorings and the considerable expence involved,it is is not a cheap option.
Buying a fast sports boat with a view to ending up in Nice or Cala Or is one way of going about things if you only intend using your new boat for a brief period over here during our "summer" ,in say ,the Solent area,however if you are in the north east (for instance )and want to use it all year round a SD with fly or at the very least some sort of decent cabin would be very useful.
Something else to bear in mind is that speed is going to cost you money,lots of money,any twin engined decent sized boat at 20knots is going to use 15/30 gallons an hour ?.
With fuel prices still on the up say to £1.00 per litre thats min £70 pounds an hour,lets say a couple of hours there and back........nearly £300 pounds.
A displacement boat would use a quarter to a third of that,but take much longer to get there.
You pays your money............ /forums/images/graemlins/smile.gif
 
Just taking another angle on this. Enjoyment of boating is often proportional to the people you're with. If any of your family are at all prone to seasickness then they will only go out once in your new displacement boat.
I see that you're interested in the S34, it's an excellent Med boat but also look at the S37 (or the later S38) because it's likely that you will want to trade up in a year or so.
As for Med costs £3500 marina fees (incl elec & water)
Annual boat service £1300 (not incl engine, I DIY that)
Fuel €1 per litre
transport of boat £6000 'ish
....try and find a boat with A/C already fitted.

Never seen that happen in a following sea, in a head sea I'll grant you.

[/ QUOTE ]Mmmm.... maybe I didn't explain my scenario properly, 'cause in a head sea that CAN'T happen. Sure, big breaking waves in a head sea can hammer the boat to pieces, but the risk in a following sea is different.
If you keep a 20kts speed in a following sea with 10' or so breaking waves, normally you're travelling faster than the waves - not much, but faster.
As long as the "breaking" part of the equation is not too bad, you can handle that.
But if and when you'll find a proper breaking wave, you could climb it without realizing in advance what's in front of it, with the result that as soon as the hull overtakes the crest, the boat falls in a 10' or so hole before hitting the water again.
I'm glad that you never experienced that, because trust me, neither the crew nor the boat would have appreciated.
 
Well, I'm told a wave can do 18 knots, so if I'm doing 20, I'm only really doing 2K. The only problem, is flying down one wave and stuffing the bow into the next, then doing a cart wheel, or broaching. Loads of boats do that. Mine dont, the bows always lift.
 
Again thanks for all your use full advice

To try and clarify my position a bit more!

Im fairly flexible about a berth at the moment but it would either be south coast or west cost, thats as much thought as i have given for the berth! Im not thinking of any further afield than France as a cruising destination maybe next year!

I am not overly concerned about the cost of diesel and or the fuel econmy!! as long as it is a diesel engine or engines thats ok!

Marina costs/maintenance will be similar which ever type of hull i go for!

I will mainly be using the boat with my wife and very occasionally with family and friends and i do mean occasionally!!!! maybe a bigger boat would be better but i think that 11 mtrs would be fine for me at the moment, as you say trade up in a couple of year or so if i need to.

I think from reading peoples comments on here the choice of hull is pretty much a personal thing, but i still appreciate the feed back
 
"If any of your family are at all prone to seasickness then they will only go out once in your new displacement boat. "

Or you can do this in tent boat......
Right is everybody holding on tight,will not be able to move around until we stop and sorry no body on the rear sunpad cos you will slide off....and no kids on the front pads cos to dangerous Ready....
Bang .......bang ......bang.......bang slam........thud bang .........thud bang.........slam ........bang bang bang ....whossh ......bang bang thud thud bang bang whoosh.....Bang .......bang ......bang.......bang slam........thud bang .........thud bang.........slam ........bang bang bang ....whossh ......bang bang thud thud bang bang whoosh.........slam ....Crunch............bang bang bang ....whossh ......bang bang thud thud bang (loosen grip with one hand to wipe watering eyes)
This excruciating assualt on the senses continues for the entire journey or until the adonis at the wheel realises that his friends are not all ex SAS and are just hoping at some point this torture will stop.
Still on with to trip .
Bang .......bang ......bang.......bang slam........thud bang .........thud bang.........slam ........bang bang bang ....whossh ......bang bang thud thud bang bang whoosh.....Bang .......WhamWhamWham....bang ......bang.......bang slam........thud bang .........thud bang.........slam ........bang bang bang ....whossh ......bang bang thud thud bang bang whoosh.........slam ........bang bang bang ....whossh ......bang bang thud thud bang........
Stunned and still hanging on for dear life,brave ex friends adjust to the fact that awful noise and driving wind has abated and try to tidy themselves up a bit.Only to realise that this palaver is only halfway over.
O god we have got to go through this all again on the way back.
Just like banging your head against a wall .......wonderful when it stops.

An hour later your displacement chum arrives,cool calm and collected and a few hundred quid better off,to spend a pleasant time in his spacious airy saloon with his appreciative passengers or sitting comfortably on his aft deck.
A quick call to his boat ensures that 99% of your friends or everybody over the age of 15 has found an urgent excuse to go back in a more civilised manner on his boat. /forums/images/graemlins/grin.gif
 
That made me laugh reading it but it aint really true. Any sea that creates bang bang in an 11m 20kt P boat creates rolling seasickness in an 11m D boat. So it's just a question of which form of torture you want. In fact, in either boat you stay in port if you havea choice. In 11m territory (no stabs) there are no seas that are horrid uncomfortable in a P boat but lovely comfortable in a D boat

I've said on here before that a P boat is a D boat too, you just slow down. Conversely a D boat can't P. So that alone makes a P boat better. OK, so a P hull isn't ideally suited to D running but both are lumps of plastic with a pointy front, they aren't that much different.

When you get to 20m territory it's different cos the D boat tends to be heavier and have stabs, and those things make it better in rolly seas

More to amuse than to inform here's a little clip of a semi-D boat of about the size discussed going upwind in F4-5. If memory serves, there would have been complaints from some family members about the rolling although the camera operator (No.1 offspring) seems to be having quite a good time.

 
Yup, broaching can be awful, to the point that it can capsize the boat, but slowing down doesn't always/necessarily cure that risk.
The situation I described is strictly speed related, and you can only slow down in advance to avoid it, 'cause if and when you climb that proper breaking wave, and you realize only when you're on its crest that there's nothing but air below the hull in front of you, choices are actually very restricted.
You can only hold on tight, NOT throttle back, and hope that the boat won't fall apart upon landing.
Been there, done that. The rest of the cruise was at displacement speed for good, and I don't think it would have been any different with another boat, unless an order of magnitude bigger ('twas a 46' in that case).
 
A lot goes through your mind in those seconds(free falling), the hull is a strong thing, it is the internal furniture and fittings that do all the flexing and separating.
/forums/images/graemlins/blush.gif
 
Precisely. And among the internal stuff in that occasion there was also a couple of massive GM diesels.
Luckily, neither it was my boat nor I was helming. But after that jump, I rushed to the e/r because I was fearing that both blocks went through the hull and straight to the bottom. Obviously they didn't, but:
upon arrival we found that one of the flaps had been completely ripped off, and the other one was bent;
both shafts alignment had to be re-adjusted;
among the mess in other internal fittings, one of the two fire estinguishers screwed above the engines on the roof of the e/r fell off.
Which was actually useful, 'cause the owner/helmsman resolved to slow down when he saw the fire estinguisher in my hands. That was worth more than any previous recommendation.
