Making a trailer for Freeman 22 Mk. 1
Padraig Breathnach
I would like to have a trailer for it, and think that the best option is to
have one made. It would be very useful to have an indication of the best
positions and angles for the support arms. I know that it could be done by
inspecting the hull, but the boat is in the water!
If anybody has ideas, or sketches, or has a suitable trailer from which
measurements might be taken, I would be grateful for a reply.

It would be fairly easy to set all the side supports just high enough
to keep the boat off the trailer mudguards, winch the boat onto the
trailer and then jack it level and adjust the rollers as required.

I have one or two difficulties with your suggestions. I live in Ireland,
where thare seem not to be too many Freeman 22 Mk. 1s, and certainly not
many large trailer manufacturers who know about boat trailers. In any
event, large manufacturers can be a great deal more expensive than small
local contractors, and I am a cheapskate!
I would hope to have a trailer built into which the boat would settle with
minimum adjustment. Some of the roads around here are a bit bumpy, and the
more rigid the trailer, the better I would like it.

IME there isn't a great deal of difference in price between
manufacturers. Most production trailers are made from the same basic
steel sections, suspension units and couplings, so there isn't a lot
of scope for variation.

It would be unusual to have a trailer built specifically to fit a
particular boat. The usual design has a central "backbone" of
rectangular section steel tube with another clamped across it at right
angles to which the suspension is mounted, and lighter "outriggers" at
intervals. Fixed to the backbone and outriggers are rollers and/ or
rubber pads which are mounted on adjustable tubes clamped to the
frame. It is these rollers/ pads which are adjusted to the appropriate
height to support the part of the boat which is adjacent to them.
This has the advantage that the trailer can be reconfigured if there
is a problem e.g. difficult to launch and recover, wrong noseweight
etc. We have done this with our 21'6" boat several times to find the
optimum configuration. One method is to set it all up so the boat sits
nicely on the trailer, then move the axle along the backbone to get
the noseweight right for towing.

When the whole assembly is clamped up tight it is suitably rigid.
I would reccomend getting a copy of the Indespension book which has
all the technical information you need to build and use a trailer of
any kind, and includes plans and parts lists (including steel spec.s)
for several trailers. I notice they now only give plans for the 1000kg
boat trailer, previous editions of the book had bigger ones. They
still suppply the bigger ones though.
Indespension is on 0800 720720, Fax 01204 309191
The manual was UKP 1.25 when I bought my copy a few years ago.

So would I!
If it would help I've got a professionally made trailer for a Norman 20
just outside, I could send you a photo if that would help.
I have recently converted a motorcycle trailer to carry a small bulb-keeled
Yacht, so you have my sympathy!

John Freeman (Sales) are run by Andrew Corless-Sheridan of Sheridan
Marine, on the River Thames at Moulsford in Oxfordshire. They run
the "Freeman Owners Club" and stock - or can obtain - any parts for the
whole Freeman range of boats. The (minimal) Web-Site is at:-

Write or call them, they should be able to give you full design details
for the type of trailer required, and (as I recall from my last visit
there) may well have a ‘spare’ trailer around for sale?
Excellent choice of boat, incidentally!!
