Wouter's PH18 Namibia

[BarraMan]

Barraman your boat weight 4180lbs don't know how much water gas and all you carry or what your normal passenger load is. But Wouter gave me his numbers for his boat and load of everything on it so I went with what he gave me. He is adding a lot of features to the base PH18

Tom, the 4180 lb weight of my boat is with 345L (91 US gal) of fuel (546 lbs), 6 x 120 amp hr batteries (heavy!), 50 lbs of ice, a 112 lb trust 72" Minn Kota Ulterra trolling motor (don't have the weight), and a 500 lb 250 hp Yamaha 4-stroke Vmax SHO outboard. We usually fish with 4 x bloke on board.

4740 lbs just seems rather heavy for an 18' bass style boat to me. There has to be something wrong with that figure. I see the hull as Jacques designed it should come in around 800 lb, so where is the additional 3940 lbs coming from?

I think Wouter gave the answer in his post above when he said that he went heavy in the weights he gave me. I am now going to worry about it until he finishes his boat and weighs it.

Hi BarraMan/Tom

Here's my spreadsheet with some estimates on weights. What do you think about it..? Anything I left out ..?

PH 18 Estimated Weights

Description: Notes: Weight
Kg Lbs
Hull Bare with fuel Tank (empty) 460.00 1,014.13
Motor Suzuki DF150 232.00 511.47
Fuel 145 Lt Tank 145.00 319.67
2 Persons 2 x 100kg 200.00 440.92
Jackplate 6 inch offset 16.00 35.27
Fishing gear All Tackle 150.00 330.69
Trolling motor (Estimate) 30.00 66.14
Coolbox Drinks + Ice 25.00 55.12
Electronics Charger + Fishfinders 20.00 44.09
Batteries X 4 100.00 220.46

Total 1,378.00 3,037.97

The Livewell takes 140lt but as it will be emty on take-off we'll keep it at zero and it will offset the fuel later in die day.

Oeps, the table came out wonky on the post.

OK, that’s looking better.

I make 145L of fuel as 145 x 0.72 x 2.2 = 230 lb

I assume you got your o/b weight from the specs. My 250 hp Yamaha is only 20 kg heavier than your 150 Suzi.

150 kg of fishing gear? Seems like a lot to cart around!

[Wouter]

Thanks for the correction on the fuel (I just assumed it would be 1:1)

Yes, got the o/b weight online. It is a 100lbs heavier then the DF140 but then the 140 is a 2lt displacement motor and the 150 is a 2.8lt
The one I have is also the Drive-by-wire version and it seems they are slightly heavier compared to the mechanical o/b.

Fishing gear, I think I added an extra 0 to that number Although the fishing gear weighs a lot I doubt it will be 150kg. Not sure what I did there.

But lets say that makes up for and anchor, chain and rope that I haven't added to the list yet.

[BarraMan]

All good ! We’ve pruned more than 1700 lb off the figure Tom used. Your Phantom should get up and go now !

Wouter, I am new to the forum and have been asking questions about bass boats. Wegcagle alerted me to your build (and BassMunn’s) and all I can say is wow! You are making an incredibly great looking boat!

I’m not quite to the boat building phase yet, but I am definitely “subscribed” to your build thread! It inspires and intimidates at the same time. Very very cool.
