Colin Archer built about 60 yachts, each to a unique drawing, half being double-enders and the other half with counter sterns. Many of both double-enders and the counter stern yachts have plum stems. All yachts have more undercut forefoot than the workboats, especially after 1897.

The beam is 22-30% of the length over the deck. (As opposed to 33-36% for the pilot-boats and the rescue boats).

All yachts, except the ''[[Asgard (yacht)|Asgard]]'', and all pilot-boats, are cutter rigged (one mast). The yachts have their main boom extending the stern for several feet that with a relatively tall mast enhanced performance. (The pilot-boats' boom normally extends the sternpost by one foot. Only the rescue boats and a few fishing boats, are ketch-rigged (two masts)). The sail area for the yachts is in the range 100-125% of waterline length squared.

On almost all boats, Archer spaced grown pine frames 2 feet c-c with a thin steam-bent oak rib between. This, together with thin, canvassed decks, made the yachts fairly light. The yachts have large ballast keels and normally no inside ballast, except a little for trim.
