Colby that Catamaran would be the Pacific 32 as flagship of the Sea Sport line of MMI. They have been around for some time. 400 gallons of fuel, and two 350 hp outboards. They have a significantly higher tunnel than the Tom Cat, and thus the better ride. The Pacific 3200 does not come up for sale often.

That's the one Bob. Too big to haul behind my F150 though. Mr. Green Michael was explaining that due to the shape of the hull, the water coming under the tunnel is forced to flow a lot faster, almost putting the ride on air.

No problem getting slung out today. I'll add some photos of that process. Would be nice if I could figure out how to upload the videos I took of the sling operation. The sling master did allow me to use the hose on the back of their office to flush my outboard, and I was able to rinse most the salt off the top half of C-Traveler while in the slip overnight at Cap Sante. Then made a short stop at a car wash on the way out of town to wash the scum off the hull at the water line. On our way home now. 2000 miles and then take a week or two off before heading out on another venture, a little closer to home! Colby

Another view of that sailboat sunk on the dock at Northwest Marine Industries. This at low tide so you can make out the hull underwater.

Some photos of C-Traveler getting slung out at Cap Sante.

But first, an ugly starfish, and a Blue Heron that showed up for a short time last night.






They lower the sling first, then hand pull the boat over it.

Some photos Rosanne took with a little history of the Cap Sante Basin.





The end. C-Traveler should pass any invasive species inspections on the way home.

Colby, what a grand adventure! Thank you for all of these photos starting with the drive to the Columbia, your travels on the river and the time you spent in the San Juans. Much has been learned and enjoyed with your sharing. Have a safe and enjoyable time in your travel back home.

I don't understand how that would work.

I get the part about flowing faster (Bernoulli), but the riding on air part I don't.

The Tom cat uses this principle also. Consider that the opening to the under the cat has sides (Hull) and top (under side of bridge deck) acting like a funnel with the air. As the boat speed increases the air cushion effect increases and the hull rides higher.

We live on the upper part of a bay, where, during northerly winds, we can get some significant chop (about 2 1/2 to 3'). We found the best ride was to accelerate the Tom Cat to 35 MPH and get her up just a little higher and it made the ride much better. Ideally the Tom Cat should have about a 6" higher tunnel (or the hulls would be 6" deeper, and the bridge deck the same place...That would give better ride at displacement speeds as well as at planing speeds.

Some Cats have "sneeze"--and this is compressed air and water which is expelled forward and then comes as a mist aft over the bow and sides. Fortunately the Tom Cat rarely exhibits this phenomenon.

But the post I commented on says that the water flows faster between the hulls resulting in "almost putting the ride on air."

Probably not the best way to put it. And to be honest, I didn't completely understand it. I do remember Michael saying that due to the shape of the twin hulls, it causes the water to move much faster underneath the tunnel. That if you look at the stern you'll see that water coming out faster than the water to the sides. There will also be a cushion of air that forms. The jest of it all is, the ride is pretty smooth even in 6' chop! Smile

Thanks Gary for the kind words. I'm sure some I just bored... Rolling Eyes Laughing Colby

I would question the 6' with any short period as being comfortable in any Cat less than 80'.

6' swells, probably good with long period.

The water has the same effect, with narrowing sides of the tunnel--but it is only on 2 dimension, rather than 3 as the air compression. The major improvement in the ride is the air cushion. As the boat goes up and then comes down, there is more compression of the air.

spotted c traveler a few days ago at the state rest area just north of my house in Marysville wa. I honked a few times but at 80mph you may have missed it. Would have stopped and said hi but did not see you in time.

If that was the first rest area south of where we come back on 5 from Anacortes, I think we stopped to make lunch. I don't remember hearing any horns, but I'm half deaf anyway... We had slung out earlier at Cap Sante, and then stopped at the last car wash in Anacortes to clean the scum off the boat. We had stopped at the other side on the way up. I believe it was Smokey Point. Had a gigantic tree base you could actually walk through. Sorry we missed you. Just arrived back home today. Got C-Traveler unloaded and pressure washed the bugs off the front. I'll be spending the next couple of days doing a thorough cleaning. Colby

Hi Colby,
Home sweet home. Love

I was showing a friend your photos of the boat being lifted onto the trailer and he said, "how do they get the straps out without them being stuck between the trailer and the boat"? I said that's a good question.

Tom

The trailer bunks have cut outs for the straps. Basically 2 separate bunks with about a 6" space between them.
