I know your post is over a year old, I just saw it. I have a Alacrity which I trailer all the time. I know the problems you talk about. If you still have questions, maybe I can help. Just let me know.

Hey thanks for the clarification. Lines on buoys is an excellent idea. That could work. I'd be able to mark the corners of the platforms and retrieve the line from the boat. Great idea. Thanks.

Sorry for not being clear. There are a few ways to rig the lines. You can have a buoy on the end so that they are floating but this risks getting wrapped around a tire or in your prop. You could also lead the lines forward to the winch platform so you could come in and get the bow hooked up then figure out the stern placement. I am sure that it is one of those things that you would figure out an improved method specific to your situation after a few times.
When I say marine railways do this, they usually have catwalks with people on them so it there is someone there to physically throw the line over. The ones without catwalks use various forms of buoys or leading all the lines to a single point.

I've seen the PVC gunwale guides used on lots of power boat trailers and I thought of that. I'm just concerned that I would break them easily. I didn't understand what you were saying in the first part of your post about the lines. How do I get the lines down around the trailer when it is under water. Is this one of those things where I will have to get wet and wade out on the boat ramp? Thanks for the reply.

There are a couple of ways to do this.
If you don't want to make any modifications to the trailer, you can lead lines up to the boat which will allow you to tie it down centered. This means that you need to avoid backing in too deep or the lines will go slack before the boat grounds out as you drive up the ramp. This is what is done on marine railways and works fine there but they are designed to take many different types of boats.
The next option would be a keel guide. It would probably be easiest to put a guide in between the keels rather than making a guide for one or both keels. Keep in mind that the guide can't be straight, it needs to start at a point and widen so that you don't have to be perfectly lined up as you drive on.
Another option is a gunwale guide. People often make these out of PVC and they work reasonably well. The advantage is that they are easily seen as you come into the trailer so it is easier to line up. The disadvantage is that they often allow more movement and don't work as well on many sailboats whose max beam is forward of the guide.

Alacrity 19 trailer question.
Hello all. Thanks in advance for the advice. I am a newb and just bought my first boat a couple weeks ago. It is an Alacrity 19 bilge keel. My question is about the trailer. Since it is a bilge keel the trailer is a bit different. The boat sets on two flat areas on the keels. I can't wrap my head around how I will ever get the boat back on the flat spots when trailering since they will be a couple feet under water. I have been considering adding a couple bunk boards that will fit inside the keels kind of like a pontoon trailer so that the boat will self center when loading. Any comments or suggestions are appreciated. Thanks Mike
