Default Invincible 35 Catamaran

Does anyone on here own the 35 Invincible Cat. I am looking at ordering one very soon possibly with twin 400s. Just would like feedback if anyone has one

Performance data from Invincible. Sea trialed one in Miami. Super impressed with the boat, but it had quad 300 V8s. Personally, I felt like that was what it needed, and I didn’t want quads. I could have been wrong and the performance report says I’m wrong, but that was my gut feeling. They didn’t have a twin 400 boat to sea trial. It was a close call, but I ended up going a different direction with my deposit.

the marina where I keep my boat is a dealer-i have seen the 35 and am impressed-several of the mechanics/dock hands have had nothing but positive comments on ride, performance, etc

Extrapolating from that - 40mph cruise / 60mph top end with a decent load (ish)...? Without having to go to quads... Sweet spot in my opinion.

I agree unless there is some drawback I am not seeing

Drawback would be if one motor goes down, you don’t have 3 remaining

I know but what are the odds of that happening really. I know it happens but I haven't had that as an issue yet. Suppose go offshore long enough it will happen.

Fished a few trips on a 35 with quad merc 300's. The boat rides soft and feels really stable even at high speeds. On a trip to the rigs with 7 people, 550 gallons of fuel, 500 lbs of ice, and full livewells we were getting 0.7-0.8 mpg running 48-55 mph.

Only thing I don't like about the boat is that it rides wetter than a lot of the other big center consoles I've been on.

What kind of seas were you in? What was wind speed roughly if you remember? Better ride than a mono of similar size?

The local Invincible dealer has a 35' with twin 400's in stock and I run a 37' with quad 300 Yamaha's with a client so I was able to go for a sea trial on the 35' to compare.

The 35' is a very impressive boat. It was calm when I took it out so unfortunately hunting down a passing ~50' trawler was about the only action it saw from a wave standpoint. The 35' seems to handle a little better than the 37' and that's not a knock against the 37' because it handles awesome, the 35' is just even better. I was only able to squeeze 60mph out of the boat but they were running different props than what Invincible normally recommends for the twin 400 package. Per the performance report above it was missing ~6mph at the top end. Hole shot was fine and fuel economy was good but was also lower than the performance report would suggest so a prop change should help that as well.

My only concern is that a 35' boat that can hold 500 gallons with fishboxes and livewells as big as the 35' catamaran has is going to get heavy fast. With 200 gallons and 4 people on board the holeshot and performance were respectable on my sea trial. The way we load down for overnight trips here in the Gulf I'd be a little worried about how twin 400's will push the boat with 500 gallons, 6 guys, 600lbs. of ice, food, water, deep drop weights, gear, etc.

I think twin 400's are probably adequate for the majority of boaters/fishermen. For the guys that really want to load the boat down and do longer trips I think quad 300 Verados to have the extra power and more importantly extra V8 torque for heavy loads are probably the way to go.

The only times I’ve fished it loaded to the gills it’s been slick calm. I’ve ran in a spaced out 2-3’ comfortably doing 45 and getting a little over 1mpg with a decently heavy load.

The boat has a really soft landing, one of the most comfortable center consoles I’ve ridden on; however, I do think that it rides wetter than a top tier 35’ boat should ride. I would say it rides better than a lot of mono hulls up to a certain point. A lot of people like to make cat hulls out to be a magic carpet, but when it gets rough they have to slow down just like everyone else. We went out a few weeks ago in some nasty conditions and had a 34’ freeman and a 36’ yellowfin riding out next to us. All of us were doing about the same speed and all of us were getting our asses kicked.

Twin 400s are roughly the cost of three 300s. You’ll have to come up with the money for one more 300 and then you’ll have quads. They won’t have to work nearly as hard as twins and you’ll still have three engines if one goes down for any variety of reasons. Twin 400s will get nowhere near the cruise speed fuel economy as quad 300s. They’ll need to be above 4500 RPM a lot and that’s where the supercharged Verados really start drinking some significant fuel. The 300s also only require 87 octane fuel, whereas the 400s require 91 octane minimum.

If I have the money to spend on a 35 Inv. How would you not get quad 300's? Motors will run much easier. Much faster cruising speed at much lower RPMS. Plus if one goes down 3 motors will still be hauling a**

Ok makes sense. 87 non-ethanol I assume correct still. And other posts. Surely the cats whether it be the invincible or Freeman handle the chop much better correct? That's all I have heard how the ride is smoother as compared to a monohaul. I have a 38ft Jupiter now.

The boat rides with a heavy bow and is pretty wet. Otherwise very nice boat with a good ride.
