Sliding Boat Hoist

It's not the area. It's a state wide DNR restriction. The other big one is it can only be one story tall and no deck on top.

That is very creative solution. I had a different issue on storing my boat trailer.

I built my house, with a double and single car garages. The ceiling in the single garage for the trailer is 11 ft tall with a 7 ft tall door. I built timber beams in the ceiling above the sheetrock. Use 4 of the same chainfalls and hoisted the trailer to live next to ceiling.

The garage door opens below the bottom of the trailer. Trailer has extra safety chains and has not been down in years since boat stays in the boathouse.

Took off the boat guides and wheels.

Its worth looking into and excactly the feedback i was looking for! 10" of my W14's is also tucked up between the truss's giving me more room under the hook. The ends are slightly beveled to clear the roof.

^ Do this. In fact I followed this exact suggestion when I built my garage (and it was Pete who recommended it then). The ends did need beveled.

Hall,
I just noticed you're from Chaska. Why would you come down to Lodi when you have so many great lakes in your own state?

Oh I agree with the anti-ugly thing Pete. On my lake in NY you are only allowed to build a house with a footprint no larger than the former house. So in some cases people have torn down a cottage and built a tall gauche house in it's place. The mcmansion theory, luckily only a few have done it.

We'Re just talking about some track here though, c'mon......

Hall,
Why the columns inside the boathouse? Clear up the area and set them in the wall. I've got W14's setting on 6x6 engineered.(LSL).

Wow Pete, that's an absurd ruling. My lake (like many here) is owned by Georgia Power so they can set their own rules, but if it's a public lake there that seems like an infringement since it would all be above the HWM, do they have some right of way over the first 10 feet or something?

Cullen,
I highly recommend consulting a structural engineer. You didn't mention the span but the description makes it about 15' min so the W8 35 seems to be on the light side.

Track/dolly systems are commercially available. Some use light rail and some C channel. I suggest a search to familiarize yourself. The switch idea won't work. As stated, the DNR is very strick on what's between the boathouse and the HWM so the switch would need to be inside the boathouse. There's not enough length!!

That seems to be simple but not as effective as building a railroad type switch. That way you can easily launch either boats quickly. What type of rail is being used?

Hi all,

I have been a long time reader, however, this is my first post.

We are building a boat house at our lake place in Lodi, WI (lake Wisconsin) and I would like to bounce an idea off of you all.

The boat house will be just off the shore and will be using a rail system to get the Nautique and out of the boat house - most people with ski boats on the lake use this system and it seems to work well. The boat house will be 24' X 28" as large as we are allowed.

The issue here is that it seems we are only "allowed" by the DNR to have one set of rails go into the lake with the boat house being wide enough to allow for two boats. With one set of rails its really only good for one boat......

The solution I am considering is adding four steel posts inside the boathouse with a 8X35 I-beam across the tops of the posts, then adding a chain-hoist and trolley per beam centered above the lifting eyes of the boats. This way I can lift one boat off the rail system bunks for cleaning and maintenance but also to "slide" one boat to the other side of the boathouse leaving me clear path to pull in another. See my attached diagram.

I would of course have foam blocks or something under the boat when I am working under it should the unfortunate happen. I have done the math to ensure the beams are able to carry the weight, I expect only .17" of deflection of the 8X35 beam with the boat suspended in the center (worst case).

Has anyone ever seen something like this done? Any thoughts on how to improve it? Any thoughts as to why this might not work?
