Nordhavn - a surprising boat!!!

Boats should look like boats,not like Gucci designer handbags with engines ............................

Now hang on Fred if you look at your quote you are refering primarily to the aesthetics of the modern boats, hence my reference to a modern shaped car as against an older boxy type. Now you are rattling on about performance, practicality reliablility?

By the way I only chose Porsche as the first one to come into my head I do not particularly like Porsches. However I could have said Aston Martin or others.

You say "should look like boats" so point remains we are talking styling.

I must be an old git then...I still haven't found a car to beat the Volvo 240 estate, as a work horse, but I have an Italian motorbike for speed.

Motor boat wise the Nordhavn would suit me nicely, with a small Riva of course.

No slippers yet though.

Gludy - just picked up this thread and was surprised by your comment on Nordhaven world pricing.

Not when we looked they didn't /forums/images/graemlins/frown.gif- which is one of the reasons we found the Marlow so attractive. /forums/images/graemlins/smile.gif

Fantastic boat - met the American boss man a couple of years ago and he took all the time in the world to show us his boat at the Southampton Boat show - found the UK agent very obliging as well.

Problem is that its just a tad too slow for me. I don't mind slow but sometimes I need to do faster!! - although my husband would love one. /forums/images/graemlins/tongue.gif

I really like the Nordhavn tough may be a bit too slow...
but it has character and is well built and finished

its design is also a bit different from the competition but shows plenty of character IMO which is something very important when purchasing a boat

now Mapis I am curius to what your 40 knot boat was.... /forums/images/graemlins/smile.gif

We have the same requirement, I need to, at times, go fast in order to get to a marinas and locks in time, run from the weather, plan a journety with more flexibility etc. Hence the boat for me is still the Marlow.

The Nordhavn 50 they have for sale would be OK for coastal work as well as blue water stuff - its aimed directly at the live aboard long distance boater but because it can cruise at low speeds offering great fuel consumption may be the answer for some after the fuel price hike in November 2008.

I thought Nordhavn were world pricing - sold in dollars. There is some extra cost for CE and there is, of course, the VAT. Maybe I am wrong, I just assumed they were because the current 50 footer, which is a CE boat, that they have dor sale is in USA$.

"Fantastic boat - met the American boss man a couple of years ago and he took all the time in the world to show us his boat at the Southampton Boat show - found the UK agent very obliging as well."

I found the same and have respect for both. I think respect for both is needed in order to enjoy the purchase of a boat /forums/images/graemlins/smile.gif

Blimey, gludy, you've not gone legal again. I'd hate to have your legal bills. Let me guess? Trader Wales more than a tad upset about your cancelled order and using the video incident to justify being bolshy? Sorry, cheeky of me
Interesting comparison between the Nordhavn strong but heavy hull design and the Marlow strong but light design. Weight is'nt an issue with a displacement boat and, if it's in the right place, it's positively beneficial so I guess that's why Nordhavn went down that route. Obviously weight is an issue for speeds above displacement speed, hence Marlow going for a light design but I am curious how the Marlow would behave at displacement speed compared to something like the Nordhavn. Does it's relatively light weight mean that it is less steady in a seaway?

Ahhhhhhhhhh. Why do you always talk about MPG?? surely the only real judge of economy is GPH?

3MPG today could be 2 tomorrow depending on tide and wind but gallons per hour are always the same for a given RPM?

All boat manufacturers and engine makers give GPH not some fictitious, ambiguous reading of MPG.

How would you work out how much fuel you need to cross the atlantic?

 

[Deleted User YDKXO]

Completely disagree. It is gph which is a totally meaningless figure because it is not related to speed and hence distance. If a boat does 10gph @ 30knots, it will go a lot further on the same amount of fuel than a boat that does 10gph @ 5knots
Take your example of the Atlantic Ocean. Say it's 3000 miles across. How exactly does knowing that your boat uses, say 10gph, help you work out whether you are going to get to the other side? On the other hand, if you know your boat does 3mpg, it's easy to calculate the amount of fuel you need. Yes, the mpg is affected by tide, currents and leeway but you can calculate the effect on mpg of these factors so it's a much more useful figure to know than gph

Mike,

My thoughts exactly. Are trader wales (forgot their new name)trying to enforce the order or keep a deposit!

Poor Gludy...he really has no luck /forums/images/graemlins/blush.gif

"Why do you always talk about MPG??"

I guess that's because people travel across distances and not across time. I don't recall ever asking me how LONG I plan to travel.

Speed of the boat is much more important than speed of the engine.

But if you find GPH works better for you, then fine. I happen to like MPG.

So how many manufacturers give mpg for their boats rather than gph?

How do you work out if you have enough fuel to get somewhere?

Personally I know roughly my gph burn at 3000 rpm (18gph) which gives me about 25 knots. If I want to go to Cherbourg I know I'll use about 40 gallons. I don't care what the tide or wind are doing, a knot or 3 of tide isn't going to make much of a difference. If was to work it out using mpg, the numbers are so low and I'd need to take tide into consideration that it's just to onerous to think about.

And suppose you set sail on a fine day for a 100 mile trip but the flat calm sea you left in, half way across becomes fairly rough. I know for a given rpm what my GPH will be, how do you work out your new mpg?

Lets have a hypothetical situation. Gludy is content to travel through the water at 6 knots doing his 3 mpg but unfortunately there is 6 knots of tide against him so effectively he is standing still. How long will his fuel last and how does he tell?

If he was using gph he'd know.. /forums/images/graemlins/grin.gif

 

[Gludy]

Mike - sometimes people can guess well but lets keep the sad bits out of this thread except to say it is me that are taking the legal steps. /forums/images/graemlins/smile.gif It is just that this thread concerns me planing my fill in boat without actually knowing when I will get my long term boat. /forums/images/graemlins/smile.gif By the way my entire legal bill for the trader problem was about £700 - I only used it for occasional advice and did all the leg work myself.

The main point:-
"hence Marlow going for a light design but I am curious how the Marlow would behave at displacement speed compared to something like the Nordhavn. Does it's relatively light weight mean that it is less steady in a seaway? "

I think without stablisers both would roll a fair amount but the Nordhavn would roll a lot more.

I know that the Marlow handles well at low speed as does the Nordhavn - I think there is little difference as lomg as the stablisers are on.

The Nordhavn is for the type of boating that i would call fast raggie - you have a very seaworthy boat that can take the weather and in getting there you accept the weather.

The Marlow allows you to run from that weather - if you wish and hence you do not have to accept it as long as you are willing to pay the extra for the higher speed.

I would be comfortable in both boats in a heavy sea.

Erm, if I look in the manual for my boat, there are graphs showing speed and range at various rpm from which it's very easy to calculate mpg. Anyway, thats immaterial because it would be very wise to check what your boat actually does, whether it be gph or mpg
Taking your example, you are mentally calculating mpg simply by stating that you are using 18gph @ 25kts. In other words you need to know the speed at which your boat consumes 18gph in order to calculate your total fuel usage. Only knowing that your boat burns 18gph without knowing it's speed won't tell you how much fuel you need to get to Cherbourg. And you should care about tide and wind because it will affect your total fuel usage. Say you had a 10kt tide against you (not realistic I know), you would use 66 gals instead of 40 gals
Taking your second example, knowing your gph would'nt help you one iota because you don't know what effect the rough sea will have on your speed and, if you did, you'd be back to mentally calculating your mpg anyway
This is a windup, is'nt it?

Have you never done navigation with tidal vectors?

No more so (in your example) than knowing mpg. [edit]correction - he may know how long it would last but not how far he will get. The former's useless without the latter.
