RealCADD is the 2D CAD program that I use for all the drawings of my designs. And I also use it to produce the CNC cutting files.

RealCADD is written and maintained by Eric Pousse, who is based in France. It is not an expensive program, but it is very richly featured, accurate and easy to use. I really enjoy using it.

RealCADD lacks a good English manual, so I have been working on producing one – in between boat design.

Anyway, it's basically done now and available at for anyone who's interested!

Cheers -- George

More 165 Instructions and drawings

I keep adding new drawings for this design at regular intervals.

And recently I have added Instructions 3 – which are for making the frames, floors and transom on the the ply sandwich version.

And Instructions 4 for the laminated version, which take builders up to hull completion (both lapstrake and cold-moulded)

Cheers -- George

Design 165 Plans Page Reorganized

On the suggestion of one of the builders of this boat, I have reorganized the Plans Download page for this design, to show the Issue Dates for each plan.

I hope this will make it easier for builders of the design to check for updates to existing plans and issue of further plans.

As with any developing design, plans are completed and issued gradually and there are inevitably new issues of earlier plans to cope with errors, changes and so on.

The most recent addition is the instructions for assembling the frames, floors and transom, from CNC cut parts (165_002_003).

With boats in build both from conventional laminated structures and ply sandwich structures from CNC cut parts, there are getting to be a lot of plans – 126 of them at the last count!

Design 165 Plans

New plans are being added for this design every week.

I haven't been able to email No 165 builders directly (because I haven't had the time to code up a means of doing so).

But for anyone who has bought 165 plans, it is worthwhile checking back every week to see new plans added.

I will be making a better system, so that builders are automatically emailed when a new plan is posted and can easily identify new plans rather than having to scroll through them all, to see which are new.

But for the moment – check back frequently! There are currently over 120 plans for this boat and growing ...

Design No. 165

165165Latest plans issued for this design include a sloop rig and a cutter rig sail plan; and drawings for the main hatch.

All the CNC cutting files (for the doghouse version) are on site too in DXF format. At the moment, these come included free with the standard design package.

Several of these boats are building now and there is a slideshow on site showing one of them (in build in Australia). I've just added the latest photos to this, which show the foredeck all fitted and the cockpit under construction.

Spritsail Rig for Design 035

For one of these small sailboats in build in South Africa, we have just designed a spritsail rig. This provides a smaller loose-footed main (no boom) and a small jib set out on a very short bowsprit.

This particular project is to give sailing lessons to local people, many of whom are disadvantaged.

The spritsail rig, with its two smaller sails and no boom to dodge is ideal for this purpose and there is the added advantage of a small sail for a crew member to control as part of the learning process.

The new sail plan can be found on the 035 plans page – scroll down to the bottom of the list of plans for the Spritsail Rig Plans.

Recently I have issued corrections to drawings for both Design 055 and 073.

On Design 055 there were a couple of incorrect dimensions on the Jig drawing; the current drawing 055/003/04 i03 is the corrected issue.

On Design 073, there were not any dimensional errors but some of the drawings were mis-labeled in the title boxes. These have also been corrected.

I am very grateful to builders who point these errors out to me, so that I can correct them.

I make the point in the instructions with every design that if something seems wrong it may not be you, the builder, at fault or not understanding – it can just as easily be me who is in error. There are literally thousands and thousands of pieces of data that go into even quite a small design and errors do creep in however careful one tries to be. And self-checking everything is never very easy.

So please do let me know if something seems wrong, inconsistent or unclear.

More No. 165 plans

I've just added plans for the lapstrake planks – Plank Nos. 1 through 7. The rest will follow shortly.

These are fully dimensioned drawings of the developed shapes of the planks, which should enable them to be set out and made without taking the shape off the frames and floors set up in the building jig.

The developed shape is the shape that has to be cut out of a flat sheet (in this case a flat sheet of ply), to be the correct shape when bent around the boat. Determining the developed shape of lapstrake planking is one of the more difficult processes as they don't exactly follow the hull shape because the bottom edges of each plank lap over the top edges of the previous plank.

To further complicate things, there is no hard and fast rule about how the planks should run, so there is a degree of choice about the matter.

The upshot is that I am recommending the builders of the first few boats which are currently in build to at least check the first two or three plank shapes from the frames etc. in the jig, in the traditional fashion. Both to ensure their accuracy and to make sure that they are pleasing to the eye.

I have also re-issued the sidedecks and foredeck plans to correct some dimensional errors. Issue 02 of both are on site now.

Again these are fully dimensioned drawings that enable builders to set out the shapes of the decking without reference to the boat itself.

Design 165 – More Rocker

In finalizing the stability and ballast keel I added a little more rocker (curve) to the underwater profile, so that I could get the ballast keel where I wanted it.

This has resulted in changes to the following drawings:

165/003/001 – Profile. New plan is Issue 03.
165/003/005 – Stem. New plan is Issue 02.
165/005/001 – Centrecase. New plan is Issue 02.
165/005/002 – Centreboard. New plan is Issue 02.
165/005/004 – Centreboard Pivot. New plan is Issue 02.

It is important that builders download the new plans. For any builder who has laminated the old-style stem, there is a change drawing available to modify the final part of the stem and a special forward deadwood..

This now allows us to finalize the ballast keel, deadwoods, sail plan and rig.
