What if?
« on: June 30, 2008, 01:28:02 AM »
If you were to do it over again what would you do differently in building your Tolman?

I would have

Made my cabin 2" shorter and leaned my windshield forward a just a bit steeper angle. I would have also been a bit more careful so that my starboard sheer line more exactl matched my port sheer line. However, I am totally happy with my boat, I love it.

  Interesting that I would have sloped my windshield *back* more and been more careful that my port and starboard chines would have been more matched. (Of course only I know that they don't exactly match) Opps! Did I just give something away??! :^)

  I would have installed a 20" square cabin hatch instead of a 16". I also would have raised my deck AND gunnell height (to match the amount I raised the deck) and sloped the deck an inch or two aft.

Rather than insisting the boat fit in the garage shop, I would've built a shelter and made the Jumbo into a 24' Jumbo rather than the 22' that I went with.  Otherwise, no changes.

I would have built a jumbo. Did not expect it to be as hard to find an acceptable used outboard.  That said, if I built  Jumbo, I probably would have ended up with a nice 70-90hp 4 stroke.
best,

I would build a 25' jumbo.  While the stretched full cabin widebody penciled out big enough for a family of 5, when you bring enough stuff for a few day trip, it gets really cramped and you can't sleep on the boat.  I'd also like another couple feet of deck for fishing.  Oh, I'd build the deck higher as well.  And, I might consider an additional 30 gallon tank to the 55 gallon tank for longer trips.

But, such a boat couldn't have been built in my garage, and I wouldn't have been able to build a seperate boat building structure, so I'll be content with my widebody.  Not to mention the family seems to prefer camping on shore.

Gee, Paul ...for 25', you can build a Great Alaskan and it'll cut the chop better and run more efficiently.  AND you'll have a wider and roomier boat to boot.  The plans cover 25'-28' plus or minus 6"...

Yes, ideal would be 28' great alaskan with twin 140's.  But, I was trying to be somewhat realistic as to what I woulda coulda done in the general scheme/budget of a Tolman skiff.

I would have gone 25' instead of 24' if I had only thought of it at the time. In the space I had I could have probably squeezed in one more foot. My stringers had at least that much extra length and I cut more than that off my side panels. It would have cost nothing more essentially.

I would have built my tolman before my cedar canoe.  The tolman is much easier to glass.  My warm us project was much more challenging with the curves and tight spaces to try and get glass and epoxy into.

Twin 140s!!!!!  Holy smokes speed queen!  The boat is powered ideally with the Suzi 175 if you build moderately heavy.  If keeping it simple, then the 140 will probably do you just fine.  That's ONE motor, not two!  I think Dave Nolan was considering twin 90's for his and that's not a bad answer either although it'll burn more fuel.  The hull design is more efficient than Renn's, so I suspect the boat will get mileage very much like a Jumbo (4+ mpg, maybe over 5).  By more efficient, I mean that the hull both maintains a more modest deadrise further forward than the Jumbo, and the GA has a finer entry as well ...luxuries that you get with a boat designed to be longer, not just stretched to be longer.

My "ideal" boat would have enough power that a single motor could get it on step, and running both capable of 40 knots.

Yes, I like speed, my motto is less time boating, more time fishing.

Light-boat performance (hull, basic gear and gas, motor, total displacement of 3800# ...about 1000# of stuff on top of the hull):
-------------------------------------------------------------------------------------
The GA-26 is predicted to do 35 knots (that's 40 mph for you lubbers) on less than 125 horsepower.

It is predicted to do 40 knots (46 mph) on less than 170 horsepower.

Even though you must account for prop-slip and unaccounted for drag to make the numbers above accurate, this is why I say a 175 hp Suzi is a fairly ideal motor to have and would be lots of fun ...but you could get away with the 140 hp if you wanted and you weren't going to push the boat to its maximum weight limits (6000#).  I'd call a 140 hp a minimum, ideal around 175 hp, and a maximum of about 200 hp.  Dave's twin 90's would've been nice.  The 28 foot version of the boat will not perform much differently.

When using the same hydrodynamics modeling software for the Tolman Jumbo, the actual boat out-performs the prediction, so I expect the actual GA to perform as predicted or better since hull loading is a tad lighter than the Jumbo and the resistance less.

See:  http://www.glacierboats.com/hydrodynamics.html

When are you going to build a GA, Paul?

In the interest of domestic tranquility, I won't even broach the subject.  It's a non starter, no funds, no motivation.

I'd like to bang out a few kayaks, and finally build my geodesic aerolite 18' canoe.  But I've been having alot of fun rock climbing with the kids, as well as putzing around the local lake.  I'm burned out on major construction projects, get back to me in 5 years, but I'm thinking the next project will be a house.

I hear you on the major projects ...I can't remember when I was without some kind of major project.  One of the things we liked about this house was that it was a no-project house (hahahahaaaaaa.)  Actually, the house projects were/are by choice.  I'm getting the wood stove that I wanted.  I like gardening and will likely put in some raised gardens.  A permanent shelter for the boat with storage and/or dry cabin(s) built into the back might be nice.

If only there was some way to take the "what if's" out of the build process. Of course this is half the fun and most of the challenge of the whole process.
