About this Gilbert Marine Gibsea 312 Plus


This Gibsea 312 Plus is probably the best example of the 312 plus in the UK today, she has been extensively upgraded and developed since her purchase in 2015.


This Gibsea 312 plus was built by Gilbert Marine in 1989 to a Rob Humphrey's design. The Plus configuration is a sportier set up with a deeper keel (1.8m) and a fractional rig, and shows her Rob Humphries racing pedigree.

Mako is probably the best example of the 312 plus in the UK today, she has been extensively upgraded and developed since her purchase in 2015.

This Gibsea features a fractional rig, with Selden anodised aluminium double swept back spreader mast (2017), Selden boom and kicker (2017), and aluminium spinnaker pole with mast track, and retractable asymmetric spinnaker pole.

Mako is powered by a Yanmar YM20 diesel engine with prop shaft. The engine is serviced every year, and professionally since 2015. She also has a 2-blade folding propeller.

The sail wardrobe features cruising and racing sails, for cruising she has 2 genoas, & battened main sail. Her racing sails include carbon battened main and No1 genoa for an additional £5,001 (together with the Code Zero). All the sails are less than 2 years old (more details below).

She is a two cabin version, and provides accommodation for up to 6+ guests with the option to create a further double berth convertible in the saloon area plus a pilot berth (7 persons). The head linings have been replaced in both fore and aft cabins.

Mako has a one bathroom aft, behind the navigation seat with a generous chart table. The L-shaped galley is located aft of the saloon and is equipped with fridge and 2 burner gas stove oven and double sink.

Mako comes equipped with an impressive inventory of Garmin navigation equipment and plotter, AIS and on-board WIFI, with everything needed for cruising and racing, including mast display, tiller pilot and wind/VMG instruments. Most of the electronic equipment (with the exception of the chart plotter) was added in 2016. Chart plotter software was updated in 2016.

Finally, Mako has had 3 seasons of JOG racing (2nd in the offshore championship this year) and been cruised to the West Country and the Silly Isles (two handed) during the past two summers. She is a beautiful yacht that has been lovingly cared for and developed to a standard beyond that of many yachts that are half her age.
