Yup, the weather does typically suck off our coast but we usually let our nuts drop, turn the engines over, put the boat in gear and fish our asses off....just like you guys!

I'm in! subscribed!

Congrats! I saw your hull (#3) in the mold last week, they must have just pulled it! Awesome, can't wait to see how your build goes and how she rides! The CC version was fantastic and can't wait to see how she shines with the pilot house version!

If that's considered typical.....and couple it with it's already California.....I'd move.
open ocean isnt usually that bad, but across the bar and in and out of the Gate can be quite dangerous.

Dangerous in the wrong boat, cat or otherwise. Flat days often become downright scary, so a boat designed for these dangerous conditions is wise.

that's not suitable conditions for any 30 footer. Gotta time the bar better. We know all about that on the Columbia river.

Correct. I fish out of the gate, and what is being described is certainly not happening all the time...

The point is somewhat valid though, that because of the afternoon onshore wind (which is very consistent in the summer) and the tide going thru the narrow gate - it can get hairy really really fast on what was a calm AM ride out. In addition to that the pacific can have large swells with decent spacing (today is something like 8-12 feet) that you don't want to keep launching off, so not a ton of days where you are flying 35mph+ offshore in a multi-outboard boat.

So the issue being described is how a boat handles following seas, and the boats referenced as 'West Coat boats' are known for running extremely bow high to prevent bow steer, low dead rise and with low planning speeds.

That said, the cat might do great. Some of those conditions are present in Australia where the hull was designed...it certainly would be awesome in the Bay which gets lots of tight chop. Really looking forward to following the build!

This is awesome. Iím excited for you and to have one of these being ran on the west coast. We have plenty of Glacier Bay 2680, 2685, and 2690 models that run out of Oregon and Washington ports and havenít lost one. Same beam but this appears to have taller sponsons. I doubt there will be an issue for even a reasonably intelligent operator.

Wow. After reading all this I realize my boat is going to be really spoiled. Go down the canal about 10 houses to the mouth of the canal. 1 mile to ocean, 1 mile to bay/gulf side. Tide swing at most is 2 ft. No chance of swamping the boat in the inlet, no inlets.

Anyone wants to move from California to Florida, I'm in real estate so give me a call.

Can we just keep the point please? Watching this awesome boat being built for a lucky new owner? I am sure he has owned boats where he lives before, I doubt he just woke up one day, decided to buy a boat and found a new small custom builder in Florida and said ďyup this should work.Ē He most likely made his purchase decision based on prior experiences in the area, and decided this awesome machine will work oerfect for HIM, even thiugh it may not be your favorite choice.

Please keep all the pics coming, its awesome to see a pallet of materials become your custom boat.

, got news for you, these type of bar conditions was what prompted Harris to come up with the design of the first Sharkcat, the rest is history, the 7.2KC was probably the peak of the design ... well that's at least before the hackers got hold of the moulds

Nothing wrong with a Radon and the wanna be Farallon and Anderson for a west coast mono but you need to get informed about this cat before you start throwing the words disaster around. Yours is a very uninformed post, really.

This cat will be 2x the boat at 1/3 the cost and 2x as fast as anything Radon has ever built, in following and even more so in head sea seas. I pass them all the time in my cat.

I have lived in Ventura, the Rincon and and in Santa Barbara since the early 60's. And although the Radon is specifically designed for our following sea waters and still also built here, it still represent very dated 80's monohull technology.

This cat has a motor bracket that overhang the transom lifting the front of the hull and the weight of the Pilot house is not a lot more than the standard CC with a ttoop. The hull also carries a ton of fuel that can also be placed rear of midships along with the transom or deck livewell's that also add another 500-1000 lbs to the twin outboard that weigh even more, each.

Should I go on?

I have to chime in on this one. I donít mind a good debate or another educated opinion but here are a few facts and a short video:

Our hulls original design is the Kevlacat out of Australia and if you think you West Coast guys go out in rough conditions, do a little research and see what an average day is for the guys Downunder. Catamarans dominate the Australian market for a reason, they donít have the nice inlets we enjoy in the U.S., they have to cross bars to get offshore.

The origional Kevlacat was always built as a forward cuddly, with an extreme amount of weight forward. Her hull design compensates for that much better then many of the cat designs built in the U.S. To my knowledge thereís only one Center Console built on the 30í (the way we measure in the U.S.) Kevlacat hull, my demo boat. All the rest are forward cuddles.

Before you watch the video, let me put out a disclaimer so this build thread doesnít get off track. The boats in this video are meant to show the extreme conditions that this type of hull can handle, not all are Kevlacats, but most are. Enjoy the video and I thank all of you who subscribe to this thread and follow Karlís dream come alive.

I'm excited to see a boat built that will be "minimally sparse "! New boats and pickup trucks have become way too fancy for my tastes.

Sorry you don’t approve of my choice in boats. Lucky for me that was not the reason why I decided to start this thread. This is not a mono vs cat thread, nor a 4 stroke vs 2 stroke thread, neither is it a google vs apple thread, there are many other threads to debate that to your hearts content. This thread is to hopefully help someone out there that is trying to research pilothouse catamarans and not finding the info they seek, for someone who is looking for ideas for there own boat or for someone who enjoys a good build thread. Let’s try to keep this thread fun, informative, and entertaining for all.

Do you have an estimate of the timeline to launch?

Dave, would it be possible to get a diagram of the layout for the pilot house design? Iím looking to see if thereís a possibility of having it be a walkaround and would like to sketch up some ideas.

Wow. That video is epic. And I cannot believe it didnít swamp when hit broadside in that one scene. Did they put ballast in these rescue Cats down under? They seem uncommonly stable. If not that is just flat out impressive.
Op thanks for sharing your build. We know you wonít let some misinformed wannabe put a damper on us Cataholics!!

Those down under conditions really suck. Lol.

In the video it doesn’t appear that those boats had brackets. Is it just the perspective on the video or is Eastwood adding a bracket to the previously existing design?
