Wooden ships comments on this Sean MacMillan Gaff cutter

Now sailing south to Ipswich, ready for inspection. An interesting  and recent yacht in exceptional condition, huge cabin, very manageable. This is not expensive for the quality.

Sean MacMillan Gaff Cutter

Designed by Sean McMillan.

Built by McMillan Yachts of Snape, Suffolk for the previous owner in 1992.


McMillan Yachts built a number of these yachts and now builds the Spirit range of yachts in Ipswich using the same proven construction techniques..

The yacht was in first ownership from build to 2007, lived on  the Clyde, sailed every season and was stored under cover every winter October to April. She cruised the West Coast of Scotland and the Hebrides and has inevitably experienced  her share of bad weather, never causing her pensioner owners any concern and giving better than expected windward performance for a gaff cutter.

Sold by Wooden Ships in July 2007 to the present owner and remained on the West Coast of Scotland, sailing every summer from her mooring on the Isle of Sky and wintering ashore under cover, mast out.


She is presented in very good condition, fully equipped and ready to sail.


The design is traditional on deck but with a modern yacht profile below the water and features a good beam, long keel with interesting cut-away fore foot, a knuckle at the water-line to a straight stem and a wide, slightly raked and radiussed transom stern.

Good freeboard, the topsides finished in immaculate varnish.

Low profile coach-roof with an interesting design showing a slight Dutch influence with an eye-catching upward sweep to the roof  incorporate the entrance hatch aft.

The generous beam allows a wide coach-roof while still leaving safe wide side decks.

Spacious, deep cock-pit with radiussed after end, tiller steering on transom-hung rudder.



The hull is built with edge-glued strip plank 15mm x 44mm convex/concave edges glued with epoxy glue and edge fastened with bronze Gripfast nails, overlaid with 3 layers of mahogany veneer on the outside, 2 layers double diagonal 3mm mahogany epoxy bonded + one layer horizontal 5mm mahogany following the sheer line and finished with Epiphanes varnish.

Below the wl she has 3 layers of diagonal 3mm mahogany on the strip planking + a layer of epoxy and glass cloth and anti-fouled.

The rig is well proportioned and easily worked from the wide safe clear deck and her performance surprises many modern yacht owners.

First owners sold and retired after 16 years very happy, trouble-free years sailing.

She was a second boat for her current owners and  has been such a great success they are now selling to build a new larger version.

The yacht is offered for sale, fully equipped, fitted-out and ready to be launched for next season.
