Her condition can only be described as stunning and reflects the considerable care her owners have taken over the boat, rig, electronics and equipment.

Owner's Comments of the Corby 34

Boat constructed by the boat builder Lucas Adriaanse in Holland, designed by John Corby in Cowes UK.
Lucas built it using the best materials and techniques for his own use, but also as a prototype boat for use in the local area ( Almere / Amsterdam) as he was hoping to do a production run for the local sailors. Ultimately a large group of owners opted to buy a fleet of X-35's, and so the production run plan was shelved. Local racing was done under the ORC rating system, which penalises stability, hence a relatively lighter keel was fitted for this reason. However, John Corby specified the hull design to allow for a much heavier IRC type keel if needed in the future. The hull is made with kevlar and closed-cell foam-core sandwich construction, using epoxy resin and vacuum bagging for the strongest light-weight construction. This will not absorb moisture, unlike GRP, and so the hull remains light and osmosis is not possible.

Boat purchased by current owners, sailed to the Solent in the UK in November / December.

Replaced the instruments with a new Raymarine ST60+ package.

New carbon rig installed with rod rigging

New Vetus M2.06 engine installed, 2 cylinder 16hp. This replaced the light-weight single cylinder Ruggerini RM90 10hp engine, which in my opinion was a bit under-powered for the boat.

Custom cradle made for the boat in Hamble. This was designed to be easily dismantled for transportation. Foam cored hulls really should have custom-made cradles to prevent high pressure points from non-custom cradles.

New IRC keel, full racing design - hollow steel fin and lead bulb, designed by John Corby. Keel fin is 154kg, bulb 1154kg, total 1308kg. This is a 38% increase in keel weight from the original keel, lowering the IRC rating, but a 73% increase in bulb weight. Hence much more righting moment, leading to a much better performing boat and a lower IRC rating. We decided to keep the bulb relatively light so as not to kill the downwind planing ability, even though a heavier keel would probably give better overall IRC results. However, the keel is designed to take a heavier bulb if desired. Personally I think the bulb should be increased by another 200kg, giving better upwind performance and a lower IRC rating (and will still be a very fast boat downwind anyway). If I was keeping the boat this is what I would do next.

New carbon fibre rudder with upgraded Jefa rudder bearings. With the stronger carbon rig and more powerful keel design the boat was more powerful and the rudder had to be upgraded to match. The boat sails beautifully with the new rudder, really well balanced both upwind and downwind. The retractable carbon bowsprit pole also had to be upgraded for the extra power too.

The boat was switched from an asymmetric retractable bowsprit configuration (i.e. like J boats) to a conventional spinnaker pole setup but with a short stubby fixed bowsprit for flying Code Zeros etc (i.e. like the Corby 36 "Yes!" configuration, which won Black Group overall in Cowes Week in three consecutive years 2013-2015). This configuration is better suited to sailing in the strong tides of the Solent, when having the ability to square back a pole to sail in the shallows out of the tide along a coastline is a big advantage over an asymmetric sailboat. The fixed stubby bowsprit also allows for Code Zeros and furling asymmetric spinnakers to be used, allowing for a wide range of sail options. This is considered by John Corby to be the optimal configuration under IRC, and so it proved for Yes! It does require a regular well-practised crew though, which is something I did not have in 2015 / 2016. However, the boat can easily be switched back to the retractable pole asymmetric sailboat configuration if desired

2016 - 2019
The owners moved to Canada in 2016 and 'Oxygen 111' has been only lightly used since for a couple of events. A decision has been made to sell in Autumn 2019 as there are no plans to move back to the UK.

The owners believe the potential of the boat has not been fully realised yet. In 2011 the boat was dramatically improved (and the IRC rating lowered) by replacing the keel and the rudder. In Cowes Week 2011 I still had a regular crew, and we got two firsts and a third and a fifth place in the highly competitive IRC Class 3 division. After 2011 I was only coming to the UK from May or June through to August, and so was not able to keep a regular crew going or attract the better sailors. Half the crew were usually rookies looking to learn. The potential of the 2015 changes has certainly not been realised yet, as that can only be done with a regular well practised crew and I just did not get the time to do that.

I also tried a bit of double-handed racing in 2016, and that is something that I would have really liked to pursue more in 2017 if time had allowed. The boat is very light at 3331 kg, and so a smaller sail plan will still drive the boat and be manageable for two people with a much better IRC rating.

2019 to 2023
The new owners had the standing rigging inspected and some refurbished and some replaced by Allspars in Plymouth. The short bowsprit was extended and twin tack lines fitted, the setup is now all asymetric with a fixed sprit, a better setup for non-Solent conditions. She is a great all round performer upwind and down, but likes a bit of breeze. She can also be cruised!

Corby 34 For Sale is lying in Port Hamble, Southampton, UK. At 10.38 metres (approx. 34.06 feet) this Corby is a bargain at £44,500.
