Bruce,
Try 'Stevenson Projects' { www.stevproj.com } in Carmel, CA. They are the
designers of the 'Weekender' and a LOT of other boats.

For $20 you can get a set of plans to build a wooden trailer. While it has
the 'problem' of floating, with a 300 pound boat {or a couple of handy
cinder blocks}it shouldn't be an issue.

The photo of it in use shows their 14 foot 'Pocket Cruiser' aboard - it is
as long as the trailer. HOWEVER, my 19-foot & 1200 pound West Wight Potter
rides on her steel trailer with the last 5-feet or so extending beyond the
end of the trailer. It is designed that way, with the aft bunks/supports.

'Adapting' a wood-framed trailer is a lot easier, and less expensive, than
cutting & welding steel.

Just as a by-the-by, I used an 8-foot, flat bed, 'utility trailer' to carry
a 15-foot Dory a couple of hundred miles. The only 'problem' was all the
'bouncing' because the load was so light !!

Regards & Good Luck,

I have a Veneitan rowing boat, a sandolo. It is 19 feet long, 3 feet 9
inches beam and weighs around 300 pounds. I keep it in a boathouse and
roll it in the water on a Sietech dolly. Once in a while I would like
to trialer the boat. I have checked out trailers and those available
are not suitable. Does anybody have a source on how to build a trailer?
