 Topic: 1980 SN Owners...Posted: May-08-2007 at 9:59am |

Hey guys.... MM, Jbear, on the 1980, do you have any idea what the draft of these boats are? My boat lift is the type that you drive into the dock area with the lift sitting on the ground, then once the boat is in the correct position, you lift the boat out of the water. My concern is with the water being low right now, how much clearance do I need? It's not a drive on type of lift. Is 12 inches deep enough for the boat to float onto, then lift out of the water??
Thanks for any input. |

Heath,
Used to have an 80' and I believe they draft 18" although the brochure reads 21" not under power. If your lift is like a Shorestation which sits under the water you may need a few inches more depth then the draft to clear the lift. |

12" of water surface -> bunk top *might* be enough, w/o any extra weight in the boat but that is still really close.
Doesn't draft include the underwater gear? These won't matter, so I guess you can subtract this from the draft to find out how much depth you need. |

way to little depth to work properly need about 18"-24".
keep in mind that even though the bottom of the frame work is on the bottom the bunks are going to be atleast 6" higher or more. |

FWIW, if you barely have enough water to get it on the lift.....what are you going to do if you have it on the lift and the water goes down another few inches? Please, dont ask how I know about this problem!. Boats look very funny hanging above ground.

With 12" of water depth, I agree no way but with 12" over the bunks, I don't think it would be a problem. I too have seen boats stranded on lifts after the water goes down that even 4 people couldn'd get off. In a case like that, the lift needs to be jetted (a water pump with a straight pipe on the discharge hose) down deeper into the lake bottom.

Pete, I would try lowering the cradle/boat onto a raft/row boat first to take some weight off then drag it out deeper.
I've also seen boats stranded, unfortunately never watched a rescue attempt though. |

I think 18-24 sounds about right when driving at idle, but I would be very careful about using a lift this time of year, a few days of hot, dry weather and the water will drop before you know it. We are having the same problems on conway,if we dont get some rain very soon we wont be able to get to the sandbar.

If you can't get to the sandbar, that means no pictures! I'm praying for rain!

..thanks for the responses guys....the water depth is about 3 feet, but I have roughly 12"-14" of water between the bunks and the surface of the water. I'm going to do some more measuring. The boat is on the trailer now but I wanted to get it in the water this weekend and leave it in the boathouse. MM is right, we need rain in Florida badly...if not for the boats, for the sandbar pictures!

3', that should be plenty. What kind of lift do you have? |

Agreed. 3' is about all the depth we ever have where our lifts sit. We've had both vertical and cantilever lifts and havent had a problem. |

Kevin, I seem to remember seeing a Powers Lake picture of a shorestation that you needed to use a row boat to get to because it was so far out in the lake! Was that yours? I'm talking about leaving it next to the pier and by jetting you will gain another 6 to 8". |

We only go about 20' off shore to the front legs.
Sinking a lift just seems like it would be very difficult to get it back up, and be able to set it again the following season without slowly sinking in again. The pontoon boats that some marinas use to install lifts have hydraulic arms on the bows, wonder how much weight they could lift. Possibly get enough of the back of a boat off the lift to push it the rest of the way off? |

Kevin, Up in the Three Lakes area it is done all the time. To get it out, they will pop right up after you put a jon boat or even a aluminum fishing boat under the cradle and reverse the lift. The following season the holes from the jetted legs are gone. We are fairly lucky though, that our water levels don't vari more than about 8". This year like a lot of areas it is at it's lower level. The people that end up jetting usually have larger deep V's, short piers and sallower water |

Heath: Just got on late so no sense in me commenting, you already got lots of answers.
Agree we need some rain here. You can't even get a boat off the ramp at Lake Shipp in Winter Haven where we usually go. Do your rain dance! john |
