Accord to a sketch I just created 20 feet will work on a 7.5° ramp but I think your wheels are wet on anything less step.
I had a 2 x 2 heavy wall extension fabricated with a break apart joint (trailer receiver/hitch style) but Ive abandoned that approach for some 10,000 lbs test anchor chain. Its easy to buy a few extra feet of chain. A bar means exact position to hitch but chain hooks as long as you are close enough. Straps have been banned around here for breaking. My trailer is a little customized but the ideas translate. If you do chain or strap you need fixed wheel(s) and mine where inexpensive 10,000 lbs. rear bumper casters for a class a motor home. Trailer http://www.catalina27.org/wingtip/mvc-736x.jpg One of two 10,000 lb wheels http://www.catalina27.org/wingtip/trailer-legs.jpg Its beefy but its going to outlast my needs. We have a local band of sailors that have had a rotating spare mount fabricated and welded into the A part of the trailer under the bow to a cross member. The spare is mounted on a trailer axle spindle above the rotating mount when you tow and it rotates down on the centerline so it can roll on the ramp when launching. You lose the worries about ruts on the ramp and youll be checking that spare for air before heading out. The spare tire on a trailer spindle might also work as a fixed mount if it is positioned so the hitch is only 2-3 inches off the ground when it is in use. That has the advantage of reducing the differential angle between the trailer and the slope of the ramp. This angle is the cause of the bow pulling back out of the V boa stop when you retrieve the boat. It is also the reason the bow stop on wing tips trailer is adjustable. It gets retracted to a loading position to retrieve the boat and then re-extended to plant the boat for trailering.

It has a full keel and I am launching it off my trailer so do you have any ideas there? I was thinking of getting a 20 foot piece of 2x2 tubing to use to extend my hitch. Do you think that will be enough? The keel is maybe a little over a foot off the ground and the ramp is fairly steep. >>> "Lee Scott" <lsc...@oldjags. <mailto:lscott%40oldjags.com> com> 7/8/2009 1:13 PM >>> Marc, Instructions for constructing an A-frame can be found in the 'Files' section. It's a pdf document. With a hinged mast step, though, you might be better off raising the mast using a gin pole arrangement. I think there are instructions for setting that up there as well. You can also check YouTube.com and you'll find several videos showing a number of ways to raise a mast. If the mast is completely disconnected from the boat, it probably doesn't matter which method you use. I've used the A-frame a couple of times, and it's pretty easy.

It has a hinged mast step that is set to hinge from the front. Which way would be the easiest to step the mast?
