Want to start a bit of a discussion on the suitability of small yachts – eg. Corribee for ocean passages.
We all now it can be done- there are a few examples of successful passages.
I own a Corribee and have completed offshore passages (Channel Islands-Devon etc) in it very successfully so know what I am talking about!
But a few points about increasing the displacement:
-reduces freeboard, therefore reduces angle of downflooding
-most likely raises G, therefore reduces AVS considerably.
-reduces speed of vessel, increasing passage times, therefore require more stores (increasing displacement more!) Remember Mingming had to turn back last year because she was too slow.
- Increases the righting moment, therefore all of the rig loads, reducing factors of safety.
Few other points:
- small size of vessel means it is practically invisible on radar,
- insufficient storage space for full safety equipment.
Don’t get me wrong- I fully support the concept of the Jester Challenge etc, and I did consider preparing my Corribee for long passages. But are you not fundamentally trying to do something in a yacht which is completely unsuited to the work. They are seaworthy yes, but not I don’t think with an extra 200-400kg of kit onboard.
I guess I am overall suggesting that in such a small yacht can one, even if the vessel is modified extensively can one take all reasonable precautions to ensure your safely at sea, without having to rely on the emergency services to come and pick you up?
I think that an extra 6 foot in length makes a considerable difference (remember displacement increases by a cubed function) so much greater internal volume for storage. The extra size enables more stores and shorter passages.
One last point- all the bunks are too short! I am 6"6.
What do people reckon?
