UK circumnavigation - at ave 4.85kts!

[gravygraham]

Just finished reading another circumnav book. This particular chap did it on/in a 30' sailboat with 10hp.

It'll probably be five or more years before I get my shot at it, and I'll sure as hell be taking more than ten horses with me. The plan is to buy a Targa 31, or a 35 with a fly.

Why don't you try and do it at 48.5kts by my calculations that will take less than 48 hours...you can do it in a weekend!

Spend the next year paying off the fuel bill though

Lol! That's what our old Seadoo Speedster maxed out at. Super fun but surprisingly tiring a that speed.

Having attempted it I am a bit doubtful about achieving an average like that in a boat that size.
But maybe Dylan can shed some light on his averages and we could pro-rata for the boat length.

What are you suggesting? Four point thingumy knots is a rather fast speed for a 30' sail boat?

Probably just the average speed for the period when actually moving. Not the average for the circumnavigation. It doesnt include all the days stuck in port waiting for good weather

The Botnia seems man enough for the job, not sure how long they took:http://www.mby.com/news/404673/botnia-targa-skipper-tells-of-land-s-end-rounding

Where did they put 400 gallons on a boat that size?

It would be reasonable if the wind was always on the beam or behind them & impossible if it was always heading them. It has to be a moving average & must include tide assisted motoring. But they will have spent many days waiting for good weather & fair tides I guess.

They don't, it will almost certainly have had refuelling stops & they are probably not included in the "time taken".

according to the report they did have 400 gallons on board =. Were they not in bladder tanks ?

"Setting out from Lymington at 3:00am on Thursday 11 August, Mike Deacon together with his son David, blasted Hot Lemon across the start line at 54 knots with 400 gallons of diesel on board. "

Goodness, 400 gals plus 2 adults must be close to 2 tons - 54kts with a 2ton payload is quite impressive.
