Workboat 18'

[Tylerdurden]

I have a request for a simple work boat for mooring maintenance, diving and general club workboat sometimes doing tender duties.
Will be used in well protected harbor with some currents from the river. Power 20-25 hp.

I would prefer a quick build with limited or no molds plywood on frame. I need to do this outdoors under limited cover when the snow leaves so quick is the only choice I have right now as they need it for season.

A skiff is the answer then,

a 17 footer, lots of capacity for the small amount of work it would take to build.

14-footer from WB but the plans are free if you go to this page and download the pdf.


again, simple build, possibly too small, depends on how many go diving.

FWIW, the garvey requires molds and a strongback table. helluva boat though.

How about this one from Bateau?

Simple and sturdy where the priorities set for this design. The hull is based on our flat bottom garveys like GF16 but our smaller garveys were narrow. We kept their bottoms narrow enough to fit on the width of standard sheet of plywood. The beam to length ratio of GF18 is much higher and this produces a very stable boat.
The GF18 can be kept very simple or customized with sole and center console. The plans show all these options with dimensions for all parts.
The basic version has no sole (floor) on the stringers, plain benches and a casting deck. The frames can be made either from plywood or from 1x3 boards. That no frills version should be powered by an outboard with tiller steering of max. 25 HP. She is light, cost little and will plane with 4 persons onboard.
With the sole, the cockpit is self bailing up to a displacement of 1,500 lbs.! The space under the sole can be filled with foam to make the boat unsinkable. The sole and foam also adds strength and stiffness to the hull. Thanks to the remote steering on the console, the max. HP rating per USCG calculations is 75 HP but we recommend 40 HP.
This boats transom is designed for a standard 20" shaft. The transom can easily be modified to accept other shaft lengths.
Comparisons:
The GF18 is a flat bottom garvey. While this is easier to build, provides great stability and requires less HP for the same speed, it will not go through a chop as well as a vee hull. We minimized the pounding by keeping the strong bow curvature of the classic garveys.
Our boats, while stronger, are lighter than production hulls of the same size. Compare for example with the 17' Carolina Skiff.

This one from DN Goodchild looks cool, too:


#5390--UTILITY --An 18 Ft. Work Boat
by Captain W. Mack Angas (CEC) U.S.N.
When several small boats were needed for the Public Works Division of the Charleston Navy Yard, it was considered worth while to try and fine or develop something better than the traditional bateau. We therefore decied to adopt the basic idea of a punt type outboard driven utility boat and design a boat of the size needed. The result was Utility, as handy and useful an eighteen foot work boat as could be desired for the multiudinous odd jobs that fall to the lot of the survey party and waterfront gang at a shipyard. To facilitate beaching, to give working room in the forward end of the cockpit, and to promote stability when heavily loaded forward the boat was given an unusually wide forward transom or stem, but she nevertheless has easy lines and should not be confused with the shapeless boxes that only too often masquerade as punts. Though not built or intended for speed, Utility slips over the water with surprisingly little fuss and has proved considerably faster, when driven by a 5 horse power service motor ahdna 16 foot flat bottom row boat driven by a similar motor.

Have you looked at the 18 ft utility skiff available from Dynamite Payson? I built one in 60 days out of CDX. She has held up well and is great for a crowd of people. Not a boat to take to sea but then it is a skiff. The bottom is flat with rocker. If I knew how to post a picture, I would.

Here's Payson's 18' work skiff:

Bolger's Diablo Grande

It seem like a good work boat, nothing fancy to it..

[Spokaloo]

Tyler, why not use your Rescue Minor plans for this?

Does this boat need to be planing? Will it be used for true tug duty? Draft constraints?

Two reasons, Not what is being asked for and I need a quick build.

I still think Bolger's Diablo Grande is quick to build and solid yet...

[Tylerdurden]

I will run these by the deciders and see which ones to pursue, thanks

[ben2go]

Wait!What equipment will be needed for the moorings?Davit,winches,crane?Which design will accommodate the tools and supplies needed for your job?

I may be a little late with this, but ...

That Bolger work skiff may not be the prettiest boat, but she has two strong points in her favor, given your parameters. First, she's the fastest and easiest build. Second, she'd be the most stable platform for diving or working on a mooring. Remember that she was designed for a lobsterman: with the flat bottom and plumb sides, you can stand right at the rail when working over the side.

And here's a photo:

Please keep us informed of the outcome and progress when you do start.

Since pretty, sleek, and sexy were not mentioned in your parameters, I'd go with Payson's floatin' hunk. Does what you need.

simple work boat for mooring maintenance, diving and general club workboat

You need a old fashion heavily built scow, plenty of room and stability...

These look great but it doesn't look like they sell plans. Good inspiration in the pics, though.
