Just to point out, you commented to yourself, not replied to "enoloc" :XD:

With such a sharp angle for the prow, I'd think it would tend to plow through the waves. If you are looking for it to cut through the waves, I'd think bringing back the ... meh I can't remember the words... front edge by about 5-10 degrees would make the boat a little faster.

There was a trick I remember some years ago, where, on a cruiser like this or half-cigarettes, they would make serrated cuts in the hull's profile. The impression I got was that these were 1-2" deep and in a series of 3 or 4 in a row. At speed, these serrations would create air pockets that would reduce hull drag, thus making it go faster. I haven't seen these on boat's hulls in the last 15 years or so, I wonder if there was some negative aspect I haven't heard about...

The anvil shape design on the hull is for aesthetic purposes?

Thanks for comment! I really like your feedback:-) 

Yeah, the bow is maybe a little bit to round, like a trawler, so I'll try to drag it a little bit back. I know what you mean about the air pockets, also called stepped hull. I have tried to make it in sketchup, but it is actually a pretty difficult shape to make, and have it as real looking as possible. There is no problem making the cuts, but it doesen't look good at all ( I'll send you an image of a boat i tried this on).

If i understood you right with the stepped hull, we actually use this as a common design on speedboats in Norway. Take a look at this site , they are at this point the most expensive brand in Norway when it comes to the price vs feet. They sell a lot of their S-24, which you also can get in different versions. In the S-24 Diablo(if I remember right), they use the well known Ilmor 725.

The C-32RR is also delivered with 2xIlmor 725 and has a pricetag of $770.000,- or NOK 4.600.000,- - THAT'S EXPENSIVE! When I was a kid, I alwas searched trough boats on the internet. Yachtworld,, everything, and still, at this point, Boston Whaler is a really expensive brand as well. Maybe they are cheaper in the U.S, but here an clean 18 feet outrage goes for $100.000 with Merc 200

Well, I try to make my comments as interesting as possible. :) :shrug:

It's been about 20 years since I had anything to do with ship design, and while ships and boats use similar terms, most times there are some terms for ships that are pointless for boats. Likewise, though I have always been interested in boats, some terms for boats don't translate to ships, for instance, the "stepped hull" as you correctly called it. I would like to see your pictures of a sketchup hull you tried with a stepped hull. You could post it to your scraps or I could send you a PM with my email address...

:XD: Yes, you did understand me correctly, and it seems funny to me that something I thought was new and innovative (...20-30 years ago) and might have been "too radical" and was thrown out, is commonly used nowadays. Those hydrolift boats have some very interesting stepped hulls!

Hmm. As I just mentioned, I haven't been dealing with ships for 20 years (boats even less so), so I am rather unfamiliar with current prices, but I like to compare prices, etc, so I tried my best to look them up. Sadly, Hydrolift doesn't seem to have any export sales to the States, so I can't compare prices on that.
I tried to find out how much a new bostonwhaler 18 foot outrage sells for, but it's all hush-hush salesmanship. Roll-Eyes Smiley
Still, I found some "new" prices for outrages, though they seemed fairly scattered in cost. The most likely reasons were they are different LOAs. I did spot some that were 37' selling for about $500,000, I also spotted a 2013 outrage 190 for $49,000
Aha! I just found one webpage that let me build an Outrage 190... Base model with a 200 merc outboard (200 XL L4 DTS Mercury Verado FourStroke engine $4,405.00) is $53,420. With all the electronics, etc $83,090.

Thanks! It is still in the ''try out'' stage, so it might be some changes with windows and general shapes. I agree that there is something about the back of the boat. Currently I havent started on that one yet, but the main idea is to have it curve all the way around the back, to get it smooth and give it that little extra. Teak deck is also going to be installed, but i make all the parts myself, so it takes a lot of time to do it.

I really like the design. One point would be the back of the boat, but I do not know how to curve the lines to allow it ot glide better over the surface of the water.
