Semi Displacement advice

[BruceK]

Thanks. I’ve heard talk on this forum of SC whine but really heard it for myself. Am I right to assume that the more modern D series engines with a SC are not as noticeable?

There is a very noticeable difference even in the later KAD engines. I have early KAD42's and the manifold is thin aliminium tube with rubber bellows. The KAD44 is thick steel piping and doesn't have the flimsy bellows as the 42's. As a result when a friends KAD44 hit the SC the only way he knows it's hit the SC is by feel or a voltage drop according to him. I would assume the D series is as quiet if not quieter. I have given consideration to replacing my intake manifolds with those of a 44 if it proves the same fit. But really the hunting you are hearing is only in those few instances shown in the vids and definitely not the norm. Hunting is bad but sometimes unavoidable for short periods.

Hi Failcon,

Here's one unique opportunity to Nordic tug 32 highly seaworthy boats and the popular "Trawler" US / Canada demanding the coastline as you do in the UK. LOA 34'2", LWL 32 weight about 8000kg + Fuel 776litres, water 376 litres.

1 x 280hp and max 17kn and normal cruising speed about 7kn / +1000nm 14kn/ nm? or at any speed, fuel consumption vs speed is a fairly linear increase, at least in the NT37 model.. The boat has been built heavily and with high quality eg hull was a guarantee for 10 years blisters and others. These boats were imported (UK) to Europe and for CE-B sertifications.

Have to say I like the Nordic Tugs but not sure about space on the 32 ...... or the price. Looked at 37s that, if memory serves, were asking similar. Interesting that it is lying in Scotland but being marketed by Boatshed Seattle.

The cross listing will be so it gets exposure in it's home waters where they are two a penny. It's obviously hoped someone will want 'the same boat' but with a change of scenery. They'll also be okay with the rain.

Ah, makes sense. Thought I had seen it previously on a UK Boatshed page.

Hi,

layout and price of flavor things like cars, houses etc. So this is something everyone has a right of their own view.

I believe they would think that the buyer could be a US national, it is typical of these international quality brand boats to sell around the world.

If this Nordic tug were to be sold at that cheap price for sale in the US, it would be sold immediately. Here in Europe it is not known whether you are following international journals such as a passagemaker, etc. And for this reason, the opportunity to buy a small boat that is of the same quality in a series of prestigious US as Nordhavn, Fleming, Selene and others.

Here's a small example of this basic boat already for about 20 years on the market first NT37 later on NT39 although the same hull, now NT40 small change Hull and face lift windows and still it won the 2016 vote, an interesting long life cykles boat, maybe it's a thing to keep yourself seeing and experiencing , the pictures do not tell you everything.

Yep, I take the point about values in the US. I was comparing it with a couple of 37’s we have seen for sale on the south coast of the UK over the last couple of years. No question they are a quality boat but as you say not so well known in Europe and not to the taste of the ‘mass’ market. I get the impression that ‘Trawler’ types are more popular in the US.

I really liked the non-flybridge 37 (same as yours?) and thought it could do pretty much whatever we might want to do with a boat be it coastal or inland.

Respect to Bruce and Firefly (and especially their families) for getting out there in inclement weather.

I must admit, I'm more in Bouba's camp, more worried about how I'm going to park the thing at the end of the day. In fact when the forecast shows a wind speed that's in double figures I get a bit nervous!

 

[BruceK]

I think the difference here Pete is I live on the hook and the only time you will ever see me in a marina is for the brief time it takes me to fuel up and take on water. I loathe marinas with a passion. Glorified car park and ghetto if you want my honest opinion.

Pete, you keep your boat in the sun so don't blame you for not taking it out the rare days its a bit crappy. If you keep your boat in the UK then ruling out the inclement days can cut your boat season by 50% or more and parking a semi displacement boat with a nice deep keel means wind has far less effect than on a planning hulled boat.

I was the OP and thank you all for you valuable experience and input. Portofino – thanks for comments and videos. There seems to be a strong vote for a planning hull with good deadrise (deep V) and shaft drive. Helpful comments from Firefly625, Keith-I and Bandit. Weather conditions around Channel Islands very relevant to here in Lyme Bay (particularly in southerlies and easterlies). The comments that all boats are compromises are particularly true in boating and while I do not choose to go out in particularly bad weather even “ordinary” poor weather can make a small boat uncomfortable.

There is an interesting discussion on Shannon lifeboat design here:
https://www.maritimejournal.com/new...aunch/rnlis-latest-lifeboat-ready-for-service

“The hull forms considered included a semi-displacement round bilge type with chine rails and a deep ‘V’ prismatic hull form. The eventual choice was for a double chine, warped form accommodating a wide, stable working platform with flat aft planing sections, high angle of deadrise amidships and a fine entry forward”.

But I am after a cruising boat not a lifeboat. I want a comfortable boat about 32-34ft or thereabouts that is going to live on a mooring rather than in a marina and cruise along the UK South Coast and Channel Islands, Scilly Isles etc. Being able to sleep reasonably soundly in an anchorage is also a consideration together with good guard rails at a reasonable height (not knee high apologies) and good solid deck hardware and anchoring gear. So a sports cruiser is not what `I am looking for. Neither do I need a flybridge (but have no objection other than cost, weight and windage). The question I suppose I have is what pilot house cruisers with high deadrise angle planing hulls and good deck gear should i consider and can I potter with them as well as 20kts+

I must admit I hanker after a Hardy 32 as a (rather skewed) compromise. Its an SD that is more biased towards planing than many SDs but it still seems to have the weight to carry it through a head sea. I looked at a few stats:

Disp Engines (typ)
Hardy 32 6.5 t 2x250
Aquastar 33 7.0 t 2x225
Humber 34 8.2 t 2x225
Nimbus 320 3.7 t 1x230
M. Fisher 805 3.3 t 1x200

The SDs in my size range (including my existing Merry Fisher 805) see to break down into two categories - heavy displacement SD vessels with well known sea keeping characteristics and a pilot boar heritage and lighter displacement SDs that have a "lively" ride. I guess that for comfort and the ability to potter and the ability to lay easily in an anchorage the heavier displacement vessels are the ones to choose - rather like a yacht but without the sails!!

Thanks to all

I have got two words for you - Fairey Spearfish

 

[burgundyben]

I've got two words for you - Triana Tantarella

 

[burgundyben]

I have got two words for you - Fairey Spearfish

Good shout.

Fantome is heavier, so tends to ride better.

 

[Scarron]

You'll correct me I am sure but I thought the Spearfish bow a bit more flared? so a bit less spray over the deck perhaps. I know they are a very dry boat anyway.

There's a few Tantarellas around with a doghouse so may suit the OP, how about this one?

There's a Huntsman 31 in Yarmouth called Vixen, she was used as the plug for the Fantome, with a few mods to lower the freeboard. Spearfish hull is the same up front, but some differences aft. Initially there was some bother with the Spearfish getting water in the back of the cockpit due to the low freeboard, so they widened the chines a little. But yes, both very dry.
