You would have to move the mast aft to make it a cutter , it would be a double headsail sloop . A boat can have multiple headsails and still be a sloop ( I've seen them with up to 4 ) .

The pulpit and other deck fittings, such as the cabin top height, are not included in the length, as I recall. The length refers to the hull only, and is used for calculating displacement. Besides, you don't need it, unless requirements have changed, and I don't think they have in this regard.. Solsken is Net 6 tons, which, as I recall, is a calculated figure representing the water displaced if the hull were submerged to the deck. What make the Ariel possible to meet the minimum tonnage (which used to be six tons, but now may be only five tons) is the full keel - the keel being part of the hull for displacment purposes.
Mike,
You wrote earlier on this thread:
I endeavored to calculate the GRT and NRT for my Ariel using the Application for Simplified Measurement at: http://www.uscg.mil/hq/msc/T3/cg5397/cg5397.form.htmOriginally Posted by Mike Goodwin
but I guessed about the depth, which I understand to be the distance from the deck to bottom of the keel. Since that varies (the sheer is not parallel with the waterline), I am a bit perplexed on how to measure that distance "D".
What values for Overall length (L), Overall Breadth (B), and Overall Depth (D), did you use to come up with 6 GT and G NT? And also where did you measure the Overall Depth "D".
Regards,

Those calcs were done back in 1960's when she was new. Once you are in 'documentation' you only re-new doc , don't have to re-apply even if doc has expired.
So , 6 & 6 were already on my paperwork for decades before I came to have the boat and I have no idea how they were decided.
Thanks For the response, Mike. I will do some more snooping around on the USCG Documentation site.
Scott
recollection is that the CG looks at measured displacment so that the fraft is from the aft end of the keel to the deck.Solsken is net 6. Hope this helps
That's not exactly true...
If you are only applying for a recreational endorsement, then all you need to show is that you have clear title to the boat. IF your boat was at some time owned in a state that issues title for boats, then you only need to show that you have clear ownership back to the title. If you can, you can apply for a "waiver of original build evidence." That way you don't have to trace the complete ownership of the boat.
This is what we did with Dasein, which had been titled in Florida two owners previous to us.

I am looking into documenting #331 and in filling out the tonnage form if I use the correct hull form (faired in keel) I do not get to 5 tons. If I use the separate keel hull form I reach 6 tons. These are both using 25'7" LOA and 6' depth.
Those that have documented, is this how you did it?

Tim,
Let me quote off the Coast Guard (Department of Homeland Security) Form:
Gross Tonnage = 6 GRT
Net Tonnage = 5 NRT
Length = 26.0
Breadth = 8.0
Depth = 7.8
Place built = UNKNOWN
(because we have no paper)
Operational Endorsements = RECREATIONAL
IMO or Other Number = 338
Year Completed = UNKNOWN
(again no actual paper accompanies the boat)
Hailing Port = SAN FRANCISCO
(recognizable port, it's gonna be large on the boat somewhere.)
Hull material = FRP (FIBERGLASS)
Mechanical Propulsion = YES
What comes after the (=) sign is on the form.
And I had BoatUS do it. I figured they knew the bureaucratic language better than I. I filled out a form to send to BoatUS and some of my numbers were altered. I argued with my handler at BoatUS that I knew perfectly well who built the boat and when and where - but because there is no provenance on paper it could not appear on the 'official' document. Bothers me.
We are issued a seven digit number that has to be permanently affixted to a structural member of the boat in 3" high Arabic numerals preceded by the abbreviation "NO."
For the formula I believe I measured from the bottom of the boat to the sheer 'somewhere', using their schematic in the request form. I have no idea where that 'depth' number came from, but that is what is there. And I don't have the guts to question it. Maybe Mike Goodwin knows - but he's lubbered on us.
And I would guess I'm exempt from registering with the state. But as long as it is reasonable as it is I'm not rocking the boat and keep paying it.
Anybody know for sure???

Does anyone have (or remember) the letter that was once posted on our forum from the NVDC saying the Ariel measured in? I thought this thread had a link to it at one time?
I did a google search. Sometimes - not always - I find things here more quickly via goole than the search function. This discussion came up - maybe it was at sailfar? http://sailfar.net/forum/index.php?topic=115.20

Thanks for dredging that up Kyle, though it does make me chuckle at my and Craig's expense

I did my CG documentation on my own - without a service. All I needed was my California DMV title. The CG didn't care about the "build history" or previous owners. It appears that info is only needed for commercial registrations. Save your money - and do it yourself! $350 is a lot of money to spend for an hour's worth of work you could do on your own.
Here's the CG documentation record for Ariel #75: http://cgmix.uscg.mil/PSIX/PSIXDetai...sselID=1108400. (The "VIN" in that record is the CG documentation number assigned by the CG. All the CG needed from me was my hull number.)
If you need a cheat sheet, use the calculations appropriate for an Ariel that are within the documentation record above.
Use this form to prove your calculations to the Coast Guard: http://www.uscg.mil/forms/cg/CG_5397.pdf
By the way, my registered "hailing port" is Omaha, Nebraska. You can use any city anywhere in the US as your hailing port, and since I'm from Omaha, I figured it was unlikely that another boat would ever be documented from there with the same vessel name. The Coast Guard just had a good laugh over that, and issued my certificate.
