inboard diesel engines?

I had the honour of joining Charlie, Sam & Will on Alfresco a little while ago and was very impressed with their whole set up so have been looking at changing my own boat since then. I must be honest I like my boat and it does almost everything i could ever want of it, but I quite like the thought of getting extra bodies on deck that (may) share the expense of the trips dry.gif .

 

I have looked at a few hulls but I dont seem able to find much information on inboard diesel engines & legs.

 

I am considering of a hull of around 1 1/2 to 2 tons and would want to be able to cruise at between 17 to 20 knotts I think I would need an engine in the region of 180 to 250HP, but they seem to cost about 3 arms and 2 legs ohmy.gifohmy.gifohmy.gif ?

 

Does anyone have any info on second hand/refurb dealers?

Been there done it and lost the T-shirt! ohmy.gif

 

The problem is with all boats, the bigger it gets so the costs rise disproportionally

 

Depending how far you wish to travel I would suggest 21 - 25ft is a good size, larger and it can be a problem to handle single handed.

 

You are then faced with the hull shape, with what you propose I would suspect something along the lines of the Aquafish or similar. You could also look at the QuickSilver 630 similar to Wishin & Abode II

 

Good luck in your quest but believe me you will always want to go bigger!

 

Re legs, Volvo are expensive if they go wrong but have been around a long time.

Engines I have only known Ford which are good plodders but can be noisy.

exponentially as well

 

If I had to choose I'd go for the Aquafish with new DTronic Merc 200 and bravoDP

Only you can make the call Graham - Coddy is right, you always want bigger... but it isnt always best!

 

Your current boat will do and go 95% of the places I'd take mine, so you do need to weigh up the costs etc.

 

I went bigger after a Warrior 165 and 175 because I wanted to cross the channel and sleep on board. However as a balance I now rarely fish inshore and miss alot of fishing as a result, many of my trips now cost upwards of

Hi Graham

 

 

We have the larger boat as the boys and I love to fish the wrecks and she makes an excellent boat to go away on for fishing and family trips.

If it was just me and just fishing my boat would be smaller and I would charter offshore or join friends.

 

Its about matching the engine to the boat, without the need to push the engine really hard all the time.

 

Shaft drive is simpler and easier to fix and lighter on maintenance costs

 

Stern drives are complicated, expensive to maintain but far more effiecient

 

Ours is a D4 Volvo on a DPH drive with duo props.

 

260 horses to give just under 32 knots WOT, but a thousand revs down still gives about 20knots.

 

Sure we burn some fuel, but with friends onboard and everyone chipping in it is manageable.

Little o'me 120hp speeds really do depend on sea state on Wishin in fair conditions she will cruise at 18/20knts when flat 22/24 and wot 26/28knts.

The bonus of mine is it sips fuel hence I'm always fishing. I.e approx 55/60 nm is 35litres biggrin.gif

But I to am seriously looking to upgrade but I'm not rushing into anything,I'll start looking at the high end and then probably lower my sights wink.gif

P.s you're always welcome Graham probably out Saturday all day

To look at diesel at displacement speeds is another option.

 

Frisky does about 2 litres per hour at 6 knots from a Volvo 28hp triple diesel engine, but that's pushing 6 tons.

 

That fuel consumption can vary quite a bit - closer to 1litre an hour in calm seas or with a following breeze (no sails) to 3 litres and hour punching into a "stopping" chop, that also reduces the top speed to about 5 knots.

 

I guess 3-4 nautical miles per litre in normal fishing conditions then.

Mike, I had a Plymouth Pilot (displacement hull) and it drove me mad being overtaken by everything! Exceptionally economical (partly because I was reluctant to go anywhere in it due to the time it took getting there and back).

 

I'm afraid I like the convenience of the speed, even if I have to pay for it.

the planing hull can almost match the displacement one in displacement mode - but then again I don't' tend to run on the open sea at 5 knots rolleyes.gif

 

Charlie's post is pretty much spot on - you really need regular company to make sense of a larger boat (that's not just economical sense). The other thing is that you need to use it regularly to both cut down on the maintenance costs (surprisingly to some!) and to also make sense of the fixed costs such as storage/mooring.

 

Since I lost my crew I have hardly used Phaeton - so much so I am seriously thinking of mothballing at my sister's place, or moving it to Greece for use a few times a year as a runabout or some such silly plan.....

Great White was semi displacement

 

at 23 ft and with 60hp shaft driven she had a max speed of 16 knots

 

in reality loaded up and a little grubby underneath, 13-14 knots

 

cruising revs about 12 knots, which gets you there eventually

 

we had a great time fishing on her, and caught some great fish but rarely went more than 15 miles.

We also limited drift fishing due to the slow return on big tides.

 

She was a nice boat, a little slow but very good on fuel, we hardly ever had to add more than 25l drum a trip and never used more than 50l

Ironic really Charlie that you used to get that from Great White, and we now have bigger faster boats capable of 30 knots plus yet the speeds above are typical of what I have had to cross the channel at the last 2 trips!! laugh.gif

 

On a more serous note Graham whislt JV tops out at 32 knots Ive never used it other than for a smile factor once a year up the harbour in winter! The serious side is that having the extra HP allows me to run a 3600rpm WOT at just 2800rpm and cruise at 18 knots.
