WEEKDAY RIB trips

Hi,


Anyone able or keen to do mid-week cross channel RIB trips? I work most weekends so rarely get chance to go out in company with other boats. People seem to organise such trips for the weekend! I've been cross-channel many times as a single boat but company would be fun! Frogs legs anyone? Just a thought.

I see you have one of the new Mercruiser 1.7l Diesels?
V. interested in your engine and boat combination as I am sure many others are on this forum.
Can you tell us all about it?
Performance, fuel consumption, rev. range etc.
(PS Have e-mailed you directly re week day trips)

Thanks Brian,

I'll contact you direct re the e-mail. As far as the boat/engine combination is concerend, it's a bit too early to tell. I've only done 6 or 7 hours so far in two short 'test' runs but it seems to be performing very nicely. Very quiet engine for a diesel! I've put the boat through the recommended 'running-in' sequence, which takes it up to full throttle for a 3-minute period. That got me 4,200 revs with 3 people and a dog on board using a 23" prop, (max revs should be 4,400). The speed obtained was 32 knots on the GPS, (sorry didnít look which way the tide was flowing but it was a neap). I'm hopeful that when the engine is run in and loosened up I should get the full 4,400 and perhaps get around the 35 knot mark, which will do me for a top speed!

As for fuel, again too early to tell but sticking my neck out, (Hi Pete), just looking at the fuel gauge and guesitmating a bit, I reckon I only used about 30 litres during a 3 hour mixed, (slow-ish) speed session on my first trip..... but judging where the fuel needle sits is not a very accurate way of judging consumption.... I'll know more after a few more trips when I fill the tank up!

Watch this space!

Can you tell us which leg you are using?
Also, being a 6.3m, does the weight of the engine make you back heavy?
Do you trail or are you on a marina?
Where are you fuel tank(s) and what is their capacity?
You are right on fuel gauges. Next to useles most of them. Do a fill-up and note NM from your GPS log and litres taken on board.
If you do this for a few months, turning the figures into a spreadsheet, you can get all sorts of interesting and useful consumption figures under diferent usages and conditions.

I could be v interested in a cross channel run' let me know when and where and I'll see if I can make it.

30 litres at 20p a liter - 6 quid that's 2 pounds an hour for fuel costs......wow. I'll be asking lots of questions on the trip. My Camel does 30 knots at 40l.p.h.

I'm planning a lunch trip to Alderney in the next couple of weeks. As and when I have a date I'll let you know. Otherwise keep touch with any plans and I'll try and make it.

Wow,

Lots of replies. I should have done this before!
Now that the interest has been aroused I will have to back-track slightly as my new engine is not yet run in. I'd like to get that done first unless you fancy progressively increasing speed from around 15 knots to 20 knots and back again all the way across. There are restrictions up to 20 hours and I've so far done less than 9! But if anyone is free in September or October, we could do something!?

Brian,
The Mercruiser 1.7 comes with an Alpha 1 leg... which I hear less bad things about than the Bravo 3! Time will tell!
It is obviously a little down at the back but rides much flatter and softer than my Ribcraft 5.85 did with twin 60hp Mariners hanging on the outside. The weight of the diesel engine is obviously spread further IN the boat. The fuel tank is towards the front, starting just behind the anchor locker and helps to balance. As for capacity......? Yes interesting one this! The capacity quoted by Humber is 150 litres. When I picked up the boat the gauge was reading just above empty as they had just put in enough fuel to test it. I then poured in 40 litres from cans, which made the gauge read getting on for a half. I then did a three-hour trip, which dropped the gauge to around a quarter. Hence my 30 L guestimate (Are you following this?). I then added another 40 litres, which brought the gauge to just over half. After another two hour trip it was down to something over a quarter. So a guestimate would say there was about 20-30 litres in the tank when I decided to fill up to the top on Sunday. It's a 150 Litre tank so I expected to put in about 120 -130 litres max....... It frothed out at 154 Litres!
So, either it's nearly a 200L tank, or the fuel barge shortchanged me or I totally wasted my money on a fuel gauge and was lucky I didn't run out!! GPS has been set and engine hours noted so watch this space! It will take several trips to get a true fuel consumption figure!
And the last question, I trail. I have it on a Rapide single axel trailer with a 1400 Kilo capacity. Just about the biggest single axel they do, but much more manageable than two (I am told!)

Hope that helps,
Mike C

I am looking to organize a cruise to cherbourg in September if you would like to come. It will probably be one of the last this year so lets see if we can get a few people interested. I will come back to you all with some dates soon.
