I am looking at building a trailer-based mast raising system for my trailer. I have an off brand trailer which never had a mast raising system designed for it. I have a couple of questions from someone who has a trailer based system with their boat.
1) How far is the bow pulpit from the mast raising post with the boat just sitting on the trailer?
2) How close does the bow pulpit come to the mast raising post when you launch and retrieve the boat? This may be different for a wing keel and water ballast and it will vary depending on how steep the ramp is, the steeper the ramp the closer it should get.

Hi Keith, I have built a trailer based mast raising system for my boat as it came with a gin pole system only, and a stock trailer.

The pulpit was in contact with the post until I bent the running light back a bit and skewed the pole slightly.

The bow comes close to the raising post but does not contact it when launching or retrieving.

Someone else a while back asked me for some photos of my system and by the time I got around to removing my tarp and taking the photos I could not find the persons e-mail address. If you would like I promise I will e-mail the photos as I have them on this computer now.

I would post them on the forum, but I don't know if it is permitted or how to do it. But I can e-mail them.

One of the easiest ways is to upload the pictures to http://imageshack.us/ and then link to the pictures there.

Keith,
I have the TrailRite trailer for the C250WB.
I can take pictures and measurements this weekend.
Send me an e-mail if you have a list of measurements.

Hi Keith,

With the TrailRite trailer, the bow pulpit on my boat sits 4" from the trailer's mast raising post. I don't recall paying attention to this area when launching or loading but have never had a problem with it.

Keith,
My wife got a digital camera for Christmas. It's quite handy.
Here are some pictures and measurements.

Bow Mast Support

Length from Pulpit to Mast Support: 4"
Length from Bow Ring to Mast Support: 18-3/4"
Length from Bow-Stop bolt to Mast Support: 20-1/4"
Height from trailer frame to Bow Ring: 39"
Height from trailer frame to Bow-Stop bolt: 36-3/4"

The Mast Support has two sections.
The lower section is fixed (outer tube).
The upper section is the moveable (inner tube).
Height from trailer frame to top of lower section: 60"
The Mast-Support pin is 1/2" diameter and 1" from the top of the lower section.

Bow Mast Support - Upper Section Post

The roller is 2" higher than the post top.
Height from upper pin to post top: 32"
Height from lower pin to post top: 78"
Total Height of upper section post: 90"

The post pin is 1/2" diameter and 4-1/2" long.
It has a hole for a hitch-pin.
The lower pin is 12" from the bottom of the post

Wow!!! Russ this was a lot more than I ever expected. Thanks for all the detail and the time it took you to compile it. It will be very useful.

Keith,
Yes, your picture is correct.
In the lower position, inner tube is above the trailer frame by 1 inch.
So you're close (60-1)+32=91 +roller=93
In the raised position (60-1)+78=137 +roller=139
You're making my head hurt.
