changing from sail to steam advice

[Sea Devil]

I am thinking of selling Paw Paw http://www.michaelbriant.com/paw_paw.htm and buying a mobo.

Also moving house from Spain to northern France - Dieppe: I know nothing about Mobo's so would be grateful for advice and suggestions.

I will use the boat for channel crossing - Dieppe - Newhaven/Brighton etc and need a cruising - economical cruising - speed of around 8-10 knots minimum. Will also cruise towards the Netherlands and Brittany. Could be displacement as I am not sure about 'planeing??' for hours on end and in larger waves I suspect it does not work...

Need twin diesel engines or at least a main engine with an auxiliary outboard. - preferably diesel if that exists. Need to keep cruising consumption down if I am to afford many channel crossings.

For accommodation probably two cabins and at least one heads/shower plus sitting outside space..

Needs to have reasonable side decks for walking on in order to moor up as I am not so nimble and will mainly be single handing.

A budget of up to 8/90,000 euro but happy to pay less

Advice on what is out there and what to look for would help enourmasly

to get economical cruising at 8 - 10 knots you will need to go at displacement speeds, so you will need a boat with a water line length of about 50 feet. Probably better to look for either a full displacement hull or a semi-displacement hull that would give you the option to go faster if needed. At your budget have a look at Trader 50 or similar. twin caterpillar engines, fuel burn @ 1mpg. Can be a bit rolly if it gets rough but built like tanks.

Alternatively a smaller 38 - 40" planing boat would give similar fuel burn at @ 18 - 20 knots. You can plane for hours at a time no problem, but you need to be more careful with the sea state. More than a F4 blowing and it starts to get hard work. On the positive side though you do get there quicker. Have a look at Birchwood TS 37, twin diesels, shaft drive, from memory a very smooth almost semi displacement like ride. reasonable room down the sides, and the aft cabin layout gives good room inside and very easy access to the upper helm as the stairs are only 3 or 4 steps. Look for volvo, cummins or yanmar engines for serviceability/parts etc.

Thank you for that information. I have looked at the suggestions and all appear to be good sea boats.

My instinct tells me that I really need to be in the 30-36 ft bracket. Single handing means I need to be able to get from the controls to the mooring lines fairly easily when the wind is blowing me off!

How about Nimbus 320 - scandinavian beautifully made, not many with twin engines but they do exist, you could always get a single engine and mount a get you home outboard on the transom. If you are worried about being blown off when single handing just radio the harbour someone will turn up to give you a hand.

They look nice. What would you guess the fuel consumption at cruising revs would be? At 2000 rpm what sort of speed through the water?

 

[Norman_E]

Are you sure you won't get bored with a mobo? I can motor at 7 knots, but that bores me, whereas I am quite happy sailing at lower speeds if there isn't enough wind to go as fast.

 

[Sea Devil]

I will be single handing and I was 76 on the 14th so realistically to handle Paw Paw at 43ft when stern to parking in a cross wind is getting more challenging.

I am re-locating to Dieppe. Lots of friends and family in Brighton and area so it's just a whizz across the channel - and be back to my youth visiting all the French channel ports

Does anyone know or can guess the fuel consumption on two engines at cruising revs would be On a grp 33 ft mobo?

Not on the plane probably but I do not know a enough to be sure..

I would expect around 20l per hour per engine for a diesel twin in that size. Cruising speed being ~ 400 rpm off max rpm on a planing boat with I/O legs and engines that range to 3600 -3800 max rpm and 160 - 220 hp

 

[No Regrets]

Fifty Shades is a 32' Stand, similar to Storebro or Nimbus, and has a pair of 165bhp Volvo's, and a SD hull, fuel consumption around 1gph at 5mph, 2gph at 8-10 9River speeds so measured in MPH, sorry!) and it's all downhill from there, although 20+kts available at huge expense :disgust:

At 16-18kt cruise I wouldn't argue with the previous suggestions of 20l per hour, as the boat averages around 4-5mpg overall.

Will you be using the boat for other purposes though? Once on the River, fuel consumption on most modest boats is not an issue, and if you're on the plane in similar sized planing boats you may have to slow down in a chop, while the Scandinavian SD vessels apparently plough through it better, but ultimately slower.

There's no perfect boat! :encouragement:

Depends whether it is semi-displacement or planing hull, shafts or outdrives. On that size boat with outdrives maybe 1.5 mpg ro 2mpg if you are lucky - maybe a little better on som boats. We used to have a Fairline Targa 35 (planing hull with outdrives) and averaged about 1.7mpg but that inlcludeed some low speed trundles upriver.

Semi-displacement with shafts it will depend on how fast you want to go but the point is that you will have a choice on speed. At semi-planing cruise (15-18 knots) I would work on around 1 to 1.5mpg - I think suggestions of 4-5mpg may be a little optimistic. All nautical mpg.

I do not intend using it on the river - only at sea but if I buy in the South of France then I will bring it back via the two rivers and canals.

Because my home will be Dieppe I need to buy a French registered and TVR paid boat with French matriculation. This should scupper any Brexit problems. I will also register it small ships probably in order to avoid UK cc issues changing flag half way across.

I will port hop the north French coast and up to ~Amsterdam and to Chenal du four area but the main use will be visiting ~Friends and relations in the Brighton - Newhaven areas

Everyone resident in France - ex pat or not has to pay an annual fee to the French Customs so it will probably be easier with Brexit to have a French registered boat. No post Brexit vat/tvr issues

At semi-planing cruise (15-18 knots) I would work on around 1 to 1.5mpg - I think suggestions of 4-5mpg may be a little optimistic. All nautical mpg.

To be clear from Dieppe to Brighton (74nm) is going to be around 90 ltrs.. per engine.
I was working on the theory that at 18knots it would be 4 hours at say 18 ltrs an hour,,,

not that different I suppose

My 34ft single engine, semi displacement boat, with a cleanish hull, at 18 knots does 84 ltrs an hour

Is that cruise or WOT? Because my 20l per hour is at gentle cruise for twins. If I go WOT I can expect those figures and maybe more combined consumption

 

[kashurst]

found an older thread featuring 2 owners, should help a bit.
http://www.ybw.com/forums/showthread.php?437221-Nimbus-320-owners-what-s-good-and-bad

have a look at aquador 32 as well - they seem to have a side door which should make single handing easy.

Yes wide open, at the moment I can’t reach 18 knots, freshly cleaned I can do a little more (but unless I put her on a diet, only about 19) so with a cleanish hull 18 is max. That’s with 425 hp and a ton of torque

Thanks I will have a look at nimbus 320 pix

You won't be able to do that for 2 reasons. First you cannot have a boat on 2 registers and second you will not be a UK resident.

Trying to buy in France will seriously limit your choice although wider EU will give you greater choice. Nothing will change in the next 3 year so if buying now you could buy a UK boat and register it in France. We have no idea what if anything will change about the status of existing boats in the future nor whether there will be any restrictions on movements so not a lot of point in making decisions now on a guess.

 

[Sea Devil]

Yes but my time scale is nearer 1-2 years and your confidence is not shared by the Dutch Government to name but one... And I will possibly remain a Spanish Citizen for some time.

Not sure what dealings you have had with the French Douane but let me assure you that anybody with a UK boat living for more than 183 days in France - a resident will like our US cousins be required to pay TVR on that boat.... That is the perceived wisdom from my friends in Brussels but of course nobody actually knows.
