More Speedy...

1. Max speed 45 + knots

has a range of a week - irrespective of how fast it goes!

PS I have a feeling that right after this one Duluth, Will or Tom, maybe taking a poll on the power options..

Sorry I have not been really active I have been busy. Can I chane my vote to More Speedy. And yes I am from Florida!

vBulletin currently does not have an option to allow people to change their own votes. But (as a moderator/admin) I have now gone in and tampered with the poll on your behalf

So I've changed the numbers from
Comfortable and speedy: 6
More Speedy: 4
Less speedy: 2
to
Comfortable and speedy: 5
More Speedy: 5
Less speedy: 2

I voted and have tried to keep myself from saying anything to influence others on this poll. With so few people voting I think we need to intensify the debate. I think the “more speed” option would be the most interesting one to work on. For “comfortable and speedy” Tom’s boat is hard to beat. For “less speed”, you can find many boats to choose from. The “more speed” option will require some outside the box thinking. Unless we just throw raw hp at it.
So, come on, VOTE, don’t just lurk out there!

Alright,

You suckered me out of my silence. More speed would be fun to work on ------ but, If the boat can not also be engineered to run well throughout its speed range comfortably, then the interest is less. There are tons of boats out there that go fast and almost none that can cruise comfortably at low planing speed.

The "secret" is no secret at all. It's power to weight ratio and planing bottom loading with a good hull design. Get these things right and it can be done. Mess up on one of them and it won't work. That's my story and I'm sticking to it.

that the more speed option will need some more lateral thinking - tight (ish) budget, noise and weight restrictions ... not going to be easy..

[Nomad]

But it will be more fun!! Thats what counts

[Nomad]

.............Right................you are with me "duluth"...................... right........guys............

[Willallison]

oh bugger it!
I put up both the speedy & more speedy options. At the moment my vote lies with the speedy option, as it would probably be a more marketable proposition, but I too tend to think that the more speedy option would be a more interesting design process - so if it comes down to a tie..........
Jeff! Please change my vote from speedy to more speedy......

WoW! I feel really warm and fuzzy inside! Weird!! =)

[Jeff]

Arg - I can't believe this poll ended in a tie... until I tampered with it once again on Will's behalf!

I'm starting to think I might get a job counting ballots in Florida - just kidding
