8.5 Hysucat vs 11-12m RIB

I was having a discussion with my crew on the weather we can operate our long distance (2+ hours each way) tours on, and (as crew do) they said we should just get a 40' boat and it would ride much better (of course! money is no issue! )

I was curious as to the mechanics behind an 8.5m (27') Hysucat operating in similar conditions to a 12m (40') rib - obviously the longer rib has the ability to span the waves and make a smoother ride, but would the catamaran and hydrofoils make the ride comparable?

An 8.5m is going to be significantly cheaper to buy and operate also.

Thanks for any input!

First of all let me say that I've never been on a Hysucat, so anything I say after this point could be complete bo110x wrg to Hysucats, but here goes:-
EVERY cat that I've been on, be it sailing yacht, Super cat large fast ferry, Safehaven Wildcat; without exception have been a horrible vomit inducing ride The way cats handle a rough sea causes a corkscrewing action that can have even the most iron stomached sailor hanging over the side.

What you do get is lots of deckspace for your money, but I'm not sure how this would work on a Seafari boat, you would end up with seats 3 abreast, so the middle row wouldn't have much of a view.

Just my 2 penneth & all IMHO.

Wot 'e sed. And likewise, never been on a Hysucat.
However I hate cats with a passion. Still vividly remember being below in a cat dive boat, and normally hardened divers, hand to mouth, rushing.....well you can guess the rest. Must have made an impression as it was over 25 years ago

Thanks for the feedback guys! I've ridden on a friends catamaran and didn't like the ride personally, I wonder how the hysucat changes that.

really like the idea of smaller more fuel efficient engines, especially running 5+ hours each day.

Diesel inboard? What are the fuel prices like in your neck of the woods?

Gas is about $4.30 a gallon, and diesel about $3.90 I think

Aren't there disadvantages to diesels over outboards for excursion boats? I would need two for reliability probably, and we'd be in the water all year.

In board can loose a lot of deck space. Some arrangements are better than others. If an engine dies it is a bigger job (more downtime) than swapping outboards.

Trimix on here has a hyuscat - not sure if he's had much experience on 12m boats to compare to but might be worth a pm. I don't think there will be many people with real competitive experience, but if they were that compelling an improvement you'd expect a greater penetration into the commercial markets here? I am sure there are advantages but rarely in boating do you gain one thing without compromising on something else.

Thanks guys for the responses - I have just heard from Trimix with his experience and it was very positive. I am looking to sea trial one here soon and will update with my thoughts either way.

I think deckspace and serviceability (down time) are the main reasons I have shied away from inboards.
