humber 5.5 outboard

timboli · 22 October 2003, 19:03

Has anyone any experience or thoughts on the abilities of a 5.5 assault with either a 90 or 115 fourstroke,Ive looked at mariner/mercury and suzuki engines,what sort of lightly loaded speed should I expect in flat water,is the extra £1500 worth it for the 115 over the 90,if I went for a 5.7 or 5.9 over the 5.5,would I notice any difference in solent type (wind over tide) chop.
Thanks in advance

If yo are looking for acceptable performance in a choppy sea do not go for the Assault. Look at the Attaque, destroyer, or Ocean Pro which are all better hull shapes than the Assault. We have both an assault and an ocean pro. Our 5.5m Ocean Pro is excellent and will (and has) out perform bigger boats in a rough sea with an exceptionally dry ride and soft landings. The Assault will not, but it does go like a rocket on a flat sea. Have a look at our website.

I agree with wavelenght, our assault is superb on smooth water and intresting in the rough however with a Yam 90 she pulls 34 Kn in the right conditions lightly loaded.

Hi Timboli,

I have an Attaque 5.3m paired with a Mariner 90Hp 2 Stroke. I find the sea keeping quality excellent.

Very sharp lines on the Bows and quite narrow in the beam compared to modern design. The chines run the whole length of the boat, flatening off at the planning quarter.

The boat handles rough water extreamely well carving her way through the water, inspires confidence knowing I will get home if the worst should happen. It is also a very dry ride for its size.

I run a 70 litre inboard fuel tank plus carry two 25 litre spares with 2 adults and kit.

I have a 13.25 X 19" Laser II stainless prop. On Flat water WOT the Gps has recorded 42 knots. Which is fast enough for me.

The boat is not too heavy either it can be handled by all my family, which helps when I need to retrive the boat.

Humber have a very good reputation for being excellent work boats, there hulls are proven plus they have been around for a very long time; 30 years plus I believe which, I think speaks Volumes.

If you are near to Portsmouth you are more than welcome to hitch a ride out in the Solent.

Regards

That about sums it up then-go for an assault for flat water but for sea going qualities go for attaque/destroyer/ocean pro - then the rougher it gets the more impressive the hull becomes

The good becomes the bad when faced with the better!

In a fair bit of chop last weekend on my Destroyer, the ride was softer at 30knots than it was at 20knots - at 20 the boat was taking off rather than slicing through... the faster speeds made everything feel a lot softer, and used the hull to absorb the waves a lot more which did feel good. Since we haven't had 'choppy' weather here for a good while, I hadn't had a good chance to play around with the trim, but with the engine tucked in quite a way, the boat did not try to go airbourne at all which really did inspire confidence.

you will be better off rigging a pair of twin 60 two stroke engines

Nah.

Why?

Trim it down a bit going into a sea- and up when running with the waves and it makes all the difference
