Topic: Average Cat Speed? Posted: 28 May 15 at 10:58am |
I'm looking to plan a long offshore trip of around 80 miles around part of the UK. As a starting point I'm looking at what type of boat to use. I think this will heavily influence all the other decisions (e.g. estimated time schedule, safety cover needs, accommodation (if needed) etc...)
A cat (e.g. F18) would obviously be a good way to cover the distance as they are relatively stable (compared to a fast mono) and very quick. My question is assuming a constant reasonable wind speed (say F3-4) what kind of distance might be expected to be covered per hour? I know that this is far from a simple answer as it depends on whether you are beating, kite angles, sea state etc. However there are quite a few long distance races out there so using them to get a rough idea of the time taken to cover that kind of distance, what are people thinking? I know the Anglesey Offshore race is 30 miles for cats and doesn't take all day, but i can't find any times as last year the course was reduced due to weather and only mono's entered. I don't know enough about the other races to be able to judge anything from them. |

Here are the East Coast Piers Race results from last year.
We sailed to Clacton and back. About a force 1-2 going out, 3-4 coming back. The full race is 48 miles round trip but we stopped at the turn mark before that so probably around 38 miles. |

Thanks, so based on all those results, an average of 5hr 15mins for 38 miles would be around 7.2 mph would be around 11 hours for 80 miles.
Gives me a starting point, thanks! |

That's encouraging, what was the boat and wind speed? I know the flatter water helps but still a good time.

flat water !!!! lochness 25 miles long on section we raced , so 25 mile fetch for waves , wind force 4 to 6 (proper ) did first year in hurricane 5.9 sx , second time solo in stealth sxl , both circa 4 hrs , 2nd race off to slow start, but wind soon kicked in , these times with 3 capsizes thrown in both races !! , both times ahead of any f18s (actually passed when suffered triple capsizes at finish race 1 through sheer fatique !), but they werent up to much in those days (rocket ships now , guess as quick if not quicker than tornado ) , first year was won by an auss pro in a Tornado who was off the planet speed wise , I thought he had retired as sooo far ahead I couldnt see him , i was second until wheels fell off my wagon with 2 miles to go !!!

Thanks for this, were the speeds due to the extreme winds? I only ask as it is unlikely that we would set off if the winds were much above a F4.
Looks to have been some epic racing though! |

sorry for getting soo carried away with Monster tales , it was truely epic racing which anyone who has done it will attest too :)
Reckon you will get best out a cat in real solid F3- F4 , vmg's down wind improve dramatically in stronger winds as you can almost dead run (assuming you flying kite ) 80 miles in a full F4 in waves could be interesting :)
