Cat 320 offshore
Hi Pat...This is a good question. There is no doubt that most boats can withstand much more than we can. I beleive she would be able to take most anything presented to her. Additionally, I am sure that there are many people making passages in these and similar boats. I consider the 320 to be an excellent coastal boat and although it is rated for all oceans, it probably would not be my first choice for a long passage. This feeling stems from a design and layout perspective more than anything else. (please see my mypost on thoughts on a generaic offshore boats). The 320 is a realitvely light boat, and as such it will be bounced and tossed around in a seaway more than a heavier boat. Additionally, the storage available for food, spares, water and fuel is less than heavier more convential offhsore vessels as a function of her flat bottom and shallow bilges. I just returned from delivering a new "offshore" racing yacht to Newport. The seas were calm for the most part and I was reminded on how much harder of a ride that boat provided over a traditional medium - heavy displacement vessel. A dear friend once asked when I was looking for my first offshore passgemaking boat, if I planned to do extended passages, I said yes. She then asked if I liked to heel, I said sure, then she asked if I wanted to cook 3 meals a day, walk around and sleep for 20 days at a 15 degree heel... I said NOT REALLY. It did then, and continues to have a major influence over my thoughts about passagemaking vessels.The important thing to remember is that for everything I have said in this post, there will be at least one person suggesting that I am wrong and that this boat or that boat has made the run. They are absolutely correct. The question is do you want to? My advice is to find a day that is absolutely ugly, one that no one would ever think about going out in, and GO out. Spend 12-14 hours out there and see what you think. A good test, might be sail out for 2 -3 days and then back in to get a feel for how she handles. I would advise upgrading the sea cocks and also modifying the cockpit drains to allow for faster discharge of water in the event you flood the cockpit.Good Luck and I hope I have provided some insight into your question.dave
