FishyFish Tolman Alaskan Skiff and Boat Building Forums

I being the obsessive kind of guy that I am, wanted to have a clue of the costs involved in the building of the Tolman Jumbo and the Great Alaskan. I have been a builder/estimator/carpenter for the last almost forty years and because of that I have a hard time taking on a project unless I know what is involved. The numbers are fairly accurate but some of the stuff I guestimated so for what it is worth:

Neal,
thanks for the insight. I modified the spreadsheets accordingly. If anyone would like a copy of the spread sheet I would be happy to forward it on, just send me a PM

Your paint estimate may be low depending on what you use. I.E. "marine" paint vs non-marine. This was one area I was short on my last build.

To be quite honest, I am sure I am short here and long there. That is why I have a contingency fund... After estimating for many years, I have learned that an estimate is simply that. It is like putting water in a bucket, you use a little here and some over there but if you are close, that is the reason for the estimate, to get you close so you don't take it in the shorts...

You 'll need at least 30 gallons of epoxy for a Jumbo.

But with careful shopping, you can reduce a lot of those other costs.

Your cost for the basic hull is off according to your prices you show you are paying for plywood by $484.00. I have the basic hull drawn up in cad and all nested so I have a good idea what it will take for materials and according to your bill of materials you are off by 2ea. ¾” & 2ea. 3/8” pieces of ply. I suspect you did not figure in the shelf/sheer deck material. If you use plywood you have to make multiple layers to build up to an overall thickness of 1 1/8” thick. If you went solely off the bill of materials in the manual it is a wee bit off from what I can see.

I am using LVL for my 28’ GA build as I do in my kits to make the shelves for a few reasons.
1) Much easier than laying up multiple layers of ¾” and 3/8” plywood to get 1 1/8”
2) I will only have two joints on each side besides the bow connection
3) Way faster build time and stronger IMO
4) Cheaper than using the marine ply you show unless you use 1 1/8” flooring plywood.
5) Cost for the LVL $435.00 this includes the 1 3/4" x  9 1/2" motor doubler

If you are going to build the shelves as per plans this extra ply is all you will need. But then if you want wider shelves in the fishing deck area you will have to build it up adding 1x2 or something to get a wider shelf for your down riggers to mount to later in the build, again lots more work. You could make them wider now but you will need more plywood than I have stated above raising cost.

The LVL I have planed for gives me 10” wide shelves in the fishing deck area and then cuts back to 8” where the shelves meet the begging of the bulwark and wheelhouse junction. I think 8” should be enough walk space to get up to the windless anchor if need be. See attached file of my lay out.

I do want to thank you though after seeing your price sheet it made me go back and look at my kit pricing for the GA and found a major error in my spread sheet of my CNC cutting time labor factor, I hate typos. I am sure pricing for a GA kit will look much better.  

For someone who maybe doesn't have the space, time and maybe carpentry ability

That would be me!!!  I will make the space and find the time to do my GA.  Carpentry ability... Well, I'm going to learn, and that will also take time.  Definitely one of Chuck's kits for me!

Chuck, you mention a 30' GA, do you have lofting numbers in your CNC for this boat?  I thought it was usually only built to 28'...

Opps my mistake it was a typo, I have talked to Brian about going to 30' I think it was in posted  on this site some time ago. I cant remember exactly what he said but it is doable but he would need to look over the numbers on the thing to be sure. At the time I was just daydreaming . Hum I wonder, 28 pretty big already I have 7 feet extra length in my garage to build.i plan to slide it closer to the front of the shop near the door it will be spring soon and can open the door for more room.
