Colin Archer Plans
Colin Archer Plans:
really messy, but the later linesplans are nicely drawn but
Be also aware that many of CA designs, as the one shown here, have too little displacement for today's fitting-out with an engine and tanks for offshore cruising. Many designs are sharp in the ends and can thus be very “pitchy” if loaded in either end with anchor chains, tanks, batteries and whatever we can put in a boat these days.
Originally there were no detailed construction plans. The boats were designed by the shipyard and details did not have to be put down on paper. Today, however, it is very important to have all the details on scantlings and construction since the boat is probably going to be built by a yard not familiar with this design.
The original interior layouts are not functional for today's use. Times have changed!
The CA sailplan can sometimes be used, like the pilot boat plan show to the right. However, today we usually use lager jibs and a taller mast so the topsail yard can be shorter.
The rescue boat ketch rig has little sail as it is designed to gale force winds. This rig has to enlarged for yacht use.
The yachts have large sail areas often with a longer mainsail boom than we like these days.
as we do more offshore cruising than we did before. Today these boats are not designed to be modern racing boats and can carry an engine for use in calm conditions. A long boom often creates a weather helm which worsens when the rudder is cut out to accommodate the propeller. The shorter yacht booms and reduced sail area is usually compensated by a taller rig and a larger jib.
There are seldom scantlings on the spars. Diameters must not be taken from the sailplan!
Too many Colin Archer replicas or copies, despite the heavy scantlings, suffer from inadequate strength.

My Colin Archer Designs
I have designed
a few Colin Archers that have been very successfully.
4 were built at Risør Trebåtbyggeri from 1979 - 1995,
32’, 38’, 42’ & 49’,
A 35’ was built on the boatbuilder school on the west coast in 1996,
45’ built in Russia 2005
49’ built in Oslo, launched 2011.
See list of my designs and rigging plans here
recommend that you choose a redesign if you want a Colin Archer.
Too many boats have not been very successful.
Conversion from a primitive fitted out boat to a boat to meet today standards with engine
without loosing the original performance, is not so easy.
I do now (from 2005) make linesplans with a computer program.
do not have ready stock plans, but I have some plans that needs
some completion or modifications.
Plans consists of the following:
Hull lines will be redrawn where necessary so steel box keel can be chosen.
Rudder and stern-post.
designs have a stern modified for propeller with an efficient and
