Oddly mounted engines!

Does anyone know if there is a reason for the oddly (angled) mounted engines in the picture above? Here's the link to the boat... http://www.boatshed.com/viewboat.php?boat=6150

Looks like my old Hysucat. The engines are angled in such a way so as to gain the maximum propulsion behind the hulls.

Yes agree with Charles there the Hysucat we had, had similar cambered engines, it also made a difference when turning the cat as they tend to turn flat with a slight lean, and when this happens you get the benifit of the cambered motors

How are those RIB's in general? Good boats? How do they take to a rough day/pounding as opposted to a single hull 6.5m?

Very wet boats in my opinion. They have a Stainless steel planing fin which sits horizontally approx two rhirds up the length of the boat and runs from one hull to the other. This helps to strengthen the structure and keeps the boats nose down in heavy seas. This allows you to keep the power on and speed up in the rough. Only problem as I see it is that keeping the bow down tends to have the boat ship a lot of water and the boats seem to constantly slamm the waves. This gets very tiring after a while. Also means you will need to get a drysuit.

tim and Gavin can tell you more. They had one for a few years and really put it to the test.

So you have done many miles in these ribs, have you?

Why do people say things when they don't have a bloody clue what they are talking about!

This is a bloody first - I agree with you. DON'T call me chuck!

Thats a lot of money for about 80 HP of boat second hand.

Hisd asking price is now £13,500 region. Personally I don't think I could ever see mee owning one, just a crazy thought...

Why is that, too expensive or don't you like the boat? Have you ever been on one, do you know anything about the Hysucat at all?

The point is, you do not need a lot of horsepower on this rib.
With twin Yamaha 50hp 4-strokes I have jumped on the plane with 14 people on board in about 4 seconds! Try that with another similar specced rib.

alt · 22 May 2006, 15:23

ct01 - I have the money, my budget is £15,500 for my next RIB. I know absolutily nothing about them to be honest. It wouldn't really suit me (the layout etc), but it does look like a damn cool boat

Charles I think Ezgoing is refeering to a particularly nasty day we ran with him in the Hysucat and being a winter day we ended up a lot wetter in the cat than Ezgoing and Katandra a 6.5 mono hull Redbay.

True the Hysucat sits up ontop of the chop, you dont get a lot of water in the front, but you do get wet in them, the hydrofoil is an amazing addition to the boat, your Hysucat had the perfect hp for it, a pair of 50 hp, you can over do it with hp, after all once you achieve hull speed, it doesnt matter whats on the back

AS for pluses, the hysucats are very manouravble

quick, efficient and dont need a lot of hp

deck rail system, hydrofoil supported
loads of storage twin redunancy, with batteries , motors and fuel system

negatives,

a few small design issues

difficult to get lower engine mounts

anchor locker leaks potentially into the hull

deck leaks fill the hull
only possible to empty whilist out of the water

stainless foil is prone to electrolisis

However the ride is different, you can run em dead flat, ontop of the surf they sit, they turn flat, get the props out quite a lot, plane almost instantly, they are weight sensitive, we shifted consul batteries and foreward fuel tanks, as we were weighed down with a pair of heavy fichts we used get 36 knots

overall the Hysucat is a good boat, if you trailer it, the water leaks will never bother you, and they are tough little boats

it's a drivers hull takes a bit of funess to wheeled the hull well.
