sandoz posted:1271's? I'm curious about the drive arrangement on that boat. The car ferries we built for Shelter Island in the 70's have a single shaft running through the center of the boat, with a prop and rudder at each end. The engine sits on a floating tensioner next to the shaft, and turns it with some sort of belt drive system. I'd bet they are 8V71's or 671's... 3 12v71's would be a fuckton of power, and an equivalent amount of space.

Just checked, and yeah they're 671s. They're going to be replaced with more fuel efficient motors soon. Also, the Gaines is 121ft, looks to be a bit bigger than the Shelter Island ferries.

We replaced a POS Cat 3406E with a 6140AL2, and even though its 100hp lower in power, its a much nicer engine. The other option is a set of JD's. The 6068 is a nice smooth, small engine that produces decent power, and they've got bulletproof reliability.

How about some lobster boat racing? These races are held in several places in Maine over the summer and are a lot of fun. I believe the record for fastest boat is 60-something miles an hour. People spend a lot of money on these races. 1000+hp boats are common.    This is the best part of the races, though, the raft. There are usually a couple giant rafts, sometimes with bands, bbqs, kegs, everything.

The boat I'm working on right now (on paper still) has two C32's, two C9's, and a pair of lugger gensets. Going to be a very crowded engine room.

The only 671's I've seen in the last decade are the one in our air compressor and the one in our Autocar.

Lt. Jebus posted:The Wallypower 118 is probably my favorite currently existing Yacht. Its pretty much completely useless, as it costs as much as much larger Yachts, has very lovely endurance, is too small for long trips but too big to be practically used as a day boat, sucks down fuel like crazy, requires at least one if not two specially trained Marine Gas Turbine specialists on every trip, and loses a ton of interior space to the engine room. Wally has only made the one and in seven years on the market no one has bought it. Is this the boat from the movie "The Island?"

I'll have to dig up some pictures of the boats I grew up working on in SE alaska. My dad currently has a '98 steel salmon tender with 2 1271's(i think). And if I can find some shots of the 24ft old coat guard rigid hull inflatable hurricane. I think top speed in that thing was around 50, and I would always go running around in the ocean in it when there were high sea warnings. 20-30ft swells in a 24 ft boat is fun! And I must say, despite how cool some of these fancy yacht are, if I was rich I would spend the money retrofitting a big old work boat into a yacht.

Hypnolobster posted:Alright, I've been spending a solid 15 minutes trying to understand the apparent windspeed/low drag boat exceeding the speed of the wind thing. The power of the sail is two factor, wind speed and volume. The speed of the craft is three factor, drag , inertia, and sail power. How the boat can go faster than wind is easier to consider if you think of the wind hitting the sail at 45 degrees than from straight behind it because you can visualize wind blowing across the sail no matter what speed the boat is going. How has no one mentioned Formula 4 yet? http://www.youtube.com/watch?v=qNdTxB5X57Y

I really want a vintage Chris Craft, one of the wood ones like a Holiday or Riviera or Capri. 23' Holiday  18' Riviera  19' Capri  The good news is they are between $20,000 and $50,000 so not that far out of reach haha. Unlike some other boats I have wanted.

Niacin posted:Not to be rude, but are you sure it was the boat and not the lawyers that won back the Cup? Considering the BMW Oracle Racing 90 handily beat the Swiss in both races with rules that both side agreed on I can't really see where you can say the boat didn't do its job. Without the lawyers it wouldn't even have been able to challenge for the cup though, so there is that. EDIT: After further review, "agreed on" is probably too strong a phrase, but the fact remains that the Yanks sailed a better race then the Swiss.

His newest creation is a van boat:   Have you made it to any of the races? As to caging the props, it's not really an option on these boats. We need every inch of draft that we can get and cages reduce performance as well, something that's important when you're a foot from rocky ledges on each side of the hull and a logging truck is backing onto the deck.

I work on boats! if anyone has any questions I'd be happy to mislead you! Ahh the invader class, the classic deep sea tugboat. 149' Bow to stern, I forget how wide, 7200 HP from 2 EMD train engines.  This is the Sea Victory class of vessel. A bit wider and alot more interior room. I took this one to brazil at the end of last year.  This is the same boat from the side.  Typical tug trash (its a term of endearment).  Leaving home If anybody wants to see more horrible pictures just let me know.

I'd rock it, too. Right the gently caress over. There's no way I'd trust that thing in a cross wind with a chop. Unless the engine is a boxer located below the axles, there's no way the CoG is within my range of acceptable. However, it'd be a hell of a party barge on a lake.

I've seen that thing on a few TV shows and I'm pretty sure the engine is a normal I6 diesel like you'd find in any other big RV, mounted with the crank roughly level with the axle. That would put most of the engine below the water level in that shot. From their FAQ: quote:It looks top heavy, is it? No, it is not. All of our weight is in the bottom of the boat. When we built the Terra Wind every single component was taken into consideration for the weight and balance of the stability It seems to be sized roughly the same as some houseboats when the slides are out, so their claims don't seem particularly hard to believe. wolrah fucked around with this message at Mar 15, 2010 around 02:58 |

If the cage is done correctly, you won't lost much in the way of performance, but I understand the draft issues. What about Kort'ing the props? Smaller prop needed, so you'd have the same draft. You could also install legs like the LCM's have. For example: http://www.lcm6.com (my website for a friend's boat thats for sale)

I've never seen pictures of them with the slide-outs out, so that makes a bit more sense. I also live on the ocean, so my take on what is a capable craft is much different than a laker. As I said, it'd make a great party barge, but I wouldn't pit it against most things in the harbor. Then again, most of the poo poo that people live on down there isn't seaworthy. A guy I worked with had his boat sink on Christmas day 2008 because the dock water line sprung a leak and diluted the salt water in the harbor.
