BoatUS- The dangers of low transom boats
"Low Transoms - The single most critical reason boats are flooded on open water has to do with transom height. Most boats that are swamped are outboard powered, with engine cut-outs that are often only inches above the waves. Motor wells are supposed to be the second line of defense when a wave comes over an outboard's transom but, in some cases, the well is too low, too shallow, and/ or not sealed adequately to the cockpit. Scuppers in the motor well and cockpit may also be slow to drain, especially if they re clogged. And whenever water lingers in the well or cockpit, the chances of another wave coming aboard increases. So too is the risk of being swamped." "A boat is often much "closer" to the water than its freeboard would indicate. A cracked thru-hull at the boot stripe or a cutout at the transom for an outboard motor well that isn't protected by a splash guard means that, as a practical matter, the boat has to sink only an inch or two before it floods and heads to the bottom. Inspect fittings and hoses above the waterline with the same critical eye that you used on fittings down in the bilge. Double- clamp the thru-hulls and consider adding an anti-siphon loop or check valve to any that are within 8" to 12" of the waterline" http://www.boatus.org/onlinecourse/R...s/section3.pdf |

All right, already, we get it. If you don't know how to use a tool, you probably should not buy it. You should always buy the right tool for your needs and use in a manner consistant with it's design, and within the limits of it's intended function. If you are skeeeeeret of a low transom boat, don't go out in one! If you are in a low transom boat, take proper precautions, if you are in a big unfloated boat, take other precautions, if you are in a dinghy.... Don't go out in a blow... Geeze guys, maybe it's time to revisit your roots, I doubt you all started boating on 40 foot trawlers;) |

This is with a 3000 pound boat, 475 pound engine, 50 gallons of fuel (about 340 pounds), two guys aboard (425 pounds), about about 150 pounds of assorted "gear." Turning a 15-1/4 x 15" Yamaha black stainless prop with a 2:1 gear ratio in the engine lower unit. Temp in the 90s, eight knot breeze, seas calm. If 16.9 gph is realistic, I think that's quite economical for that setup. What's the slip figure for that rig, if you know? |

We didn't get wet, but if you remember, I wasn't taking the rips between Warwick Neck and Patience Island for anything - I know the boat's limits. And I think Harry is right in one respect - knowing when to and when not to get into trouble is very important with this type of design. Well, that is what I am saying. First off, I am comfortable in small boats anyway, maybe too comfortable (remember the lake, the temptation to pull the tiller and send me swimming;) My first boat was a seveylor soft bottom raft, second a sears jon boat, both saw time on Long Island Sound. Anyway, I was a bit surprised the first time I saw the Ranger up close, it has less freeboard than my skiff. But once on the water, and of course trusting the Captain knows the limitations, I was not at all uncomfortable. I don't know how rough water I would be comfortable in, in your boat, but the way it handled and your ability to keep it going where you wanted it to go would probably keep me in a comfort zone. Like I said, every boat is a tool, I have 11 hammers, some folks have several boats all suited for a specific type of work/ play. It still sounds to me like Harry picked his boat cause it will do what he needs it to do... |

BoatUS- The dangers of low transom boats
Well... you wouldnt want to read what the retards up in Detroit at the Smallmouth Derby did last week on Lake Erie. 3 boats sunk (towed in by OUR Coast Guard for free ...yet they charge us.) 1 guy lost the 240 Verado engine right off the back of his boat. These were dummies that took BASS BOATS out in 3.5 to 5 foot chop. You just DONT DO THAT on Erie. S. |

And some of the "flats" and bay boats built by bass boat companies and others aren't much better in terms of freeboard or bows built to take on the kind of waves you're likely to encounter in salt water or bodies of water like the Great Lakes. The answer is to have enough experience to know where you can and where you cannot safely go with the boat you have. |

Well, maybe. My Ranger is is 8'6" beam at 19'9" and is flat out stable. That is what causes the problems - their inherent stability. The fact that they have scant freeboard isn't true either - my Ranger has 24" of freeboard in the interior which is sufficient for most seas a small boat will run in. The problem is that you can't take a bass boat with limited interior (read space) and expect it to perform the same as a bay boat in similar conditions. With respect to sea keeping abilities, anything short of 3' and I'm happy. Passengers might not be happy, but I'm perfectly fine with that. I've fished The Race, shot the Charleston Breachway and run the East Passage of Narragansett Bay in my Ranger in heavy seas - 3-4' short period piles of water. Don't confuse bass boats with bay boats. |

We didn't get wet, but if you remember, I wasn't taking the rips between Warwick Neck and Patience Island for anything - I know the boat's limits. And I think Harry is right in one respect - knowing when to and when not to get into trouble is very important with this type of design. Which has been everyone's point. Given the design, a little *more* expertise is a requirement. Many of us are not quite the calibre of boater that you and Harry are, and therefore may have trouble with that design. -- John H |

Ahh, I had a feeling you were referring to the formulae, but you were a bit oblique. You did note I posted "I'll be working to find..." According to a data sheet I have from the manufacturer, a fully loaded boat just like mine with a 150 four cycle yamaha hit 25 mph on the nose at 4000 rpm with a fuel burn of 7gph. That was with a pretty full fuel tank (619 pounds), a full livewell (250 pounds of water), 130 pounds of gear and 365 pounds of "guys" aboard. I talked to the engineer who ran that test. He believes that with my typical fuel load (half a tank, max, 310 pounds), nothing in the livewell, et cetera, I can get close to 6gph at 25 mph. We'll see. |

When I bought my 2520XL Parker, they sent me a performance sheet and when I actually took delivery of the boat, I found that their numbers were precisely on the money.

The 200 would have added some to the top end, but with the prevalent hard chop on Chesapeake Bay, there aren't that many days you can run more than 25-30 mph on a small boat. So, why have a boat that will do 45+? The 200 weighs about 100 pounds more than the 150. No advantage for the 200 there. The 200 burns more gasoline than the 150. No advantage there. As quiet as the 200 is, the 150 is quieter. The 200 will out-accelerate the 150. Yawn. |
