SeaDoo Record from Key West to Cancun

[cattaff]

Trying to set a Guiness world record to ride a SeaDoo from Key West, Fl to Cancun, Mexico..... Looking for a support group and logistics partner... let me know if your intersted!!

[pressuredrop]

i think our boats might be a little to slow for support
Good luck!

[Dale]

That sounds like a hell of a support staff.

How many refuel stops are you planning?

[cattaff]

Seadoo's use 7 - 8 gal an hour at 65mph and hold 25 gal. We can add enough fuel bladders in subsequent areas to get up to 70 gal..... should be plenty... Im looking at using 60gals tops with 10 gals reserve... to go 400 miles should take around 7 hours in good weather, so timing will be everything....

[cattaff]

are there any stopping places along the way.... Im not sure, never did the trek!

[tager]

Good luck. You could float some fuel on a raft anchored off of cuba, if the swell isn't too bad.

I don't know if you are going unassisted or not.

[cattaff]

my calculations are a little off.... my RXTiS holds 15 gals and uses 10 gals an hour... ooops so would have to find a stop or strip it down and find places for fuel in the hull... maybe pull a tube??? 65mph could be rough.... need assistance Im sure... wouldn't want to go at it alone.... impact might be better though!! not sure

Take a little time to plan this out. Nobody can see you out in the ocean on a Sea Doo unless they're within a couple of miles, it's not like a lake. We don't want to hear about you disappearing.
Also, there seems to be a bit of an oil problem in the vicinity, you might want to be sure that it's clear.

At 6.2 lbs per gallon, gas is going to get heavy real fast.

970lbs dry is the stock weight for this ski.
18.6 gal fuel tank.
16.4 gal storage.
3 rider capacity

So lets say 3 riders is 500lbs.
Assume you are 200 lbs with gear.

35 gallons of storage is already there.
Add 300lbs of fuel, since you won't be taking passengers, that's about 48 gallons more.

That's 83 gallons total. 514 lbs of fuel.

That gives you 970+514+200= 1684lbs of crap on a ski that probably is designed to plane with around 1100lbs.

I doubt you will go over 3 knots for the first few miles.

Even if you did a lot of serious mods to the ski, I would be surprised if you saved 100lbs. Also, anyone can do this in a boat, so preserving the "jetski" nature of it is important.

Maybe put a sail on it?

Or refuel in Cuba.

I guess you could do it pretty easily if you went hullspeed the whole time, but who wants to see that?

Personally, I think this feat is a pretty bad idea, it would be way more impressive to waterski all the way there.

The straight line distance between Key West and Cancun is only approximately 406 miles.

Yes, but he did it in short daily runs from one place to another. Perhaps a single non-stop trip that is longer than any of his single-day runs would still be some sort of a record.

[David M]

Is there a support boat that can go 65 knots for 400 miles and carry enough fuel for itself and your SeaDoo?

[TexSail]

Best of luck to you but your ass is going to feel like a sack of concrete by the time you hit Cancun.

Have you attempted this record yet? I am going myself and soon! Taking my 2014 Yamaha FX Cruiser SVHO. Distance of 406 miles is about right if you cut a straight line. With this straight line you would come within 20 miles of Cuba. I however would do one stop in the Dry Tortugas(68 miles west of Key West) This route adds about 10 miles to the trip but one could then refuel and Cuba would then be missed by at least 32 miles. My current plans are to have 6-5 gallon tanks of gas strapped saddlebag style over the seats with an additional 12 and 5 gallon tank positioned in the rear. Total extra gas is 48 PREMIUM GAS gallons and weighs 343 lbs at 7.3 lbs/gallon. Total gallons is then 18.5 (Jet ski tank) plus 48 = 66.5 gallons.

Above figures consider 1 person, 1/2 fuel, no water, 5 lbs of gear.


414 total trip miles minus the Dry Tortugas run of 68 miles leaves 346 miles. At 4000 RPM or 24.6 mph the 66.5 gallons would give a range of 436 miles.
At 5000 RPM or 38.1 mph the 66.5 gallons would give a range of 359 miles.

So a speed of about 30 mph would work on a calm sea and this figures in for extra weight as well. 414/30mph=13.8 hours (add 1.5 hours for refueling 9 times) and you get 15.3 hours. Leaving Key West at 3 a.m. is a MUST! Arrive Cancun between 7-9 p.m. Full moon visibility would be nice and first leg could be done at 70mph! Also, last 150 miles could be done at high speed as well.

Total cost of the premium gas would be 66.5 plus (18.5 first leg)= 85 gallons X $3.60/ gallon = $306.00. Don't forget about the return trip!

*** 10% reserve figured into above calculations.
An additional 5 gallons could be stored in front compartment.
Sufficient water, food and safety gear required!

Anyone ready to do this, lets go!! A practice run from Miami to Bimini would be great first. Give me a call Pete-407-535-7328 or email me at bonkp1@yahoo.com if interested.

Me tinks the mission is in jeopardy already when you come into a mostly sailing forum for support crew!

65mph on a bay or lake maybe, from Key West to Cancun not going to happen.
