Mist Miss - Jet Powered 145hp - Advice

Post by Rupert » Thu Mar 24, 2011 4:52 pm

Hi There,

I'm new to this forum, just signed up and so much great info. I am building a mist miss, in hindsight i wish it was the Riveria but the plans weren't available when i started the project some years back now. Just a slightly deeper V and more shape (reverse tumblehome at the front) think thats the right term. I have made a number of changes to mine, a curved transom raked forward, also brought the sheer line in at the transom for more shape to create slightly more of a barrel back. I have fitted a lightweight turbo diesel coupled to a castoldi water jet. One reason for the diesel is that the price of the fuel in the uk at around £1.40 a litre, I can run this on red diesel so much cheaper.

-I have some concerns, namely if i have put enough support in for the force of the jet, how it will handle, if i need to make mods to the hull. (hope not!)
-Also whether the engine in in the right spot to balance the boat out. I have fixed it in now but could be moved a couple of inchs forward.
-Also what is the rough dry weight of the boat, without engine/ jet. I have made from oak and ply. Just so i can get an idea of handling.
-I'm also wondering how the 145hp turbo charged diesel would compare to a petrol.

This is the engine:

I look forward to anyones input, very excited to hear back.

best

Welcome, FWIW, I deleted your duplicate post. But there should be some folks here that will be able to answer your concerns.

Regarding whether you need to add more support. If you bolted to your motor stringers, you should be good to go.

Paul Kane (aka Hot Rod) has been working on some nifty software for weight and balance. He has a little widget for fine tuning engine placement (+/- a couple of inches from the design placement). You might want to send him a note

Few things in the world measure up to the thrill and satisfaction of boating in a boat that you built.

Pic of my Mist Miss, i've made some modifications. The transom is now curved and raked forward, I have brought the sheer line in as it travels aft to create more of a barrel back. The Engine and water jet are nearly fitted.
