Humber Assault 5.5m

[Will19984713]

Hello,

I am new to the forum so please let me know if i am posting in the wrong place.

I have a 5.5m Humber Assault with a 2006 Tohatsu 90hp. Does anyone know what the 5.5m humber assault weighs without the engine (or with if anyone knows). Only reason i ask is the suspension units on the trailer need replacing and i am unsure how much it weighs in total. People have suggested a weigh bridge but this isnt practical.

Any help is greatly appreciated.

Thanks

Try emailing Humber they are normally very helpful.

Humber website is your friend with specs Rigid Inflatable Boats - a vast range of quality ribs for both leisure crafts and sports craft from Humber Inflatables

However the boat weights are only approx as they are all slightly different. You will also have to allow for weight of console and any other fixtures ie A frame etc.

You beat me to it

Hi guys,

Thank you very much. I shall have a look. I am sure i will have more questions as time goes by. I have had the RIB a few years but have never really needed to know the weights.

On a different note - I use an inboard stainless fuel tank - It doesnt have a fuel guage - Does anyone know how easy it is to fit one and where to get one from.

Thanks

I wouldn't bother as I believe that they are not very accurate.

[Will19984713]

Hi thanks for that. I did wonder how they can be accurate while moving about. The only problem is its difficult to know how much is left as the tank is enclosed in the centre console. Under the seats in the stern i do carry a 25 litre tank as a spare but would be nice to know how much i have left. I suppose another option maybe a fuel meter that measures how much has passed through it. I know the amount the tank holds so that may work.

As you know he capicity of your tank you could fit a fuel flow meter. Basically, measures the fuel that runs down the fuel line from the tank to the engine and will tell you total used, can be reset each time you fill up.

Believe they are pretty accurate, google it.

Good luck.

Thanks for the response. I will have a look. Will be a lot easier to fit as well rsther than having to take the console off to access the tank to fit a fuel guauge. Do they do fuel flow meters with a small display for the console?

Thanks Will

The one that I looket had a "standard" 2 inch ish gague so should find a space on most consoles.

[Will19984713]

Okay do you have a link. All the ones i have seen are more than a new tank with built in guauge would be

Thanks Will

Wooden dipstick marked with 1/4 1/2 3/4 & full etc. Worked well on my previous boat! Cheap & very reliable if boat is almost level?

[alystra]

Yep! Wooden dipstick for me, the fuel guage was always useless. Rectangular plastic tank, 85 litres. Filled it, marked the level, then divided that into 5 litre units. Provided you always measure at the same trim it's accurate to a couple of litres. You need flat water though.

Yep plus 1. My mate runs a Humber 6.1 and he uses the dip stick method never let h down as he knows exactly what's in the tank.

Try this F210-Fuel | Northstar

[freespirit3]

If I remember on my last assault the plate on the transom detailed all the weights for the engine and boat. Humber fit these with the hull number and the details.

But it looks like you have sorted this out now.

Hi thanks i will have a look. The dipstick method would be great but the fuel filler is not directly ontop of the tank ita on the side and goes around a U shape bend and then into the tank. So i am not sure i can use that method. At the moment i just keep it topped up all the time. Not sure what the most sensible option is.

I too have a built in SS tank (90l). I calculate my use from the mileage I do, logged every trip. When I fuel up I note how much I put in in - if from can- , and brim it when at a pump - Once you know how many litres you've used full tank to next full tank & how many miles between refills that will give a good idea of consumption. Allow a reasonable safety margin & you won't have a problem.

I know I do on average 0.85l/NM, bur keeping updating over time - it's pretty consistent though.

[Will19984713]

Thanka for all thw responses. When the rib comea back from having the engine serviced i will take a closer look at the options.
Thanks again. Will
