you might want to add a knee pad or no knee pad parameter

GTR and FPR are the only needed to apply. All others just go one direction. FORWARD.

Its really not about speed. Just trying to do a study on what might make a boat combination more efficient. The title of the thread was just to catch everyone's attention. The data might confirm or refute some propositions about what makes a boat more efficient or faster in any set of parameters one might choose to monitor. You have any suggestions on what parameters I might want to include in addition to those I listed?

1b. Ratio- GTR35
2. 33.5 MPH
3. Average RPM at Average top Speed - 3950

6. Current: Estimate or describe: None
7. # of batteries - 2
8. Cooler - 60Q Yetti
9. Cooler Weight - 20lbs + beverages
10. No. of beverage containers - 12pack + couple waters
11. Prop Pitch -10P
12. Other: estimate weight - anchor (10lbs) + flotation & who knows how much that weighs
13. Water Conditions: calm
15. Length of Boat - 18' LOA

Im gonna go out on a limb here and say Turbodrive has the fastest boat

ttt

This will help you guys out. I just used Coe's numbers cuz he posted them up. I want to show you guys an example
http://www.culverprops.com/pitchselection.htm

Fill this end and it will tell you your pitch of a prop for your given RPM, desired speed, given prop Length (diameter), and Gear ratio. Use 1.2:1 for GTR. you guys will be surpised. Below is a cliffs notes, but plug in those numbers and you can figure out wos Lying!

Engine RPM 4000
MPH 30
Reduction Ratio 1.2:1
Prop Length 12

Guess what it calculates you need a 10 pitch prop that assumes NO SLIP. We all know that there is slip in a prop

Just saying that it is hard to belive that a boat will travel 33.5" MPH at 3950 RPMS with a 1.2:1 reduction ratio with a 12x10 prop without slip.. Even though slip is ALWAYS present

James ran a 12P and couldn't turn it... I am having an 11P made right now for me... I run better with an 11P. We have been messing with the thickness of the trailing edge of the blade, adding thickness instead of honing it down like powertech does will drop your top end down but prop will last longer in the stuff... just something to think about...

OK, I've put up links to enter and view data. Please start entering data so I can test the links. Thanks.

Done.

The interface is working perfectly!!!!

Tony B was helpful in making this boat data entry thread a sticky post in the reviews section. Please take a moment to go to the top of this thread and enter your rigs data. It's pretty detailed and once I get enough data I'll analyze it and report trends regarding performance versus modifications and configurations. Your cooperation is appreciated.

I posted this junk on your site einstein! I'm kinda confused though are we building drag boats or boats to get us where the ducks are? And who really wants to hit a stump in the dark doin 40mph! Or are we building a Jeff foiles get away boats? Hmm....

TTY

Can you edit my information so that it adds a 10lb anchor & chain along with flotation...

We are getting very good entries in the boat data table. Please add your boats data so so everyone will know all the details and maybe put the information to good personal use when making a decision on what to buy or modify. See details below in my signature. thanks for everyone who has cooperated so far.

How can i go back and edit my data?

speed 24 @ 3980rpm pasanger weight 225

it was just me with beer

brandon click

Could you delete my first entry, thanks

New here, and I'm impressed! I'm getting ready to build a new boat, so seeing what everybody else is running is a great help. Thanks dguidry!

Just a reminder to post you boat's data in the database below my signature if you have new rig or haven't post your old rig's data yet. Now that season is over thought I'd remind everyone. The database is proving very useful to those contemplating new rigs and options.

Well dg Im fixen to up grade my paddle to a stage 3 paddle.
