RE: Fuel tank follow-up
Hats off and a hearty "Thank You" for all the input. The boat was listed as having a 25 or 26 gallon fuel capacity. However, on closer examination, it appeared to have only about a 10 or 12 gallon tank. Also, there was an additional deck fill (near the first diesel 'fill'). The second fill had the word 'diesel' (I think) ground off and there was some sort of 'glue' on the cap to prevent it from being unscrewed. On examination from inside the port lazarette, the hose connection had been removed. Thus, I came to the conclusion that there was an additional fuel tank that had been removed.
I would like all the fuel capacity reasonably possible, since I have some serious plans for my "new" CD.
Maybe someone can shed some light on the 'additional' deck fill. I can't imagine what else it could be other than 'diesel'. Does anyone know what the factory original fuel capacity was?
Thanks,
Paul Hierstein

Re: RE: Fuel tank follow-up
Paul,
The deck fill (bronze, labeled 'DIESEL') is located on the port side deck just forward of the primary winch.
With a Volvo-Penta MD7A at ~2200 RPM (~5 Kts) she would use slightly over a quart per hour giving about a 220 NM range. Going to 2600 RPM we could get about 6.5 Kts and close to 2 qts per hour and the exhaust 'mustache' referred to by Larry.
I also would recommend the Jerry Can approach for additional fuel / range capacity. I carried a spare 6 gal. Jerry Can on last summer's NE Fleet sails and never used it. Any permanent tanks should be stored full during the winter to prevent condensation. Recommend weighing; the condensation problem, using as much fuel in a tank before refilling, the very good 'mileage' we get and the fact it is a SAILBOAT.

The 1977 CD30 factory fuel tank was an aluminum "TEMPO" with a 12 gallon capacity (exactly - written on the tank by mfg.), deck fill and magnetic - ribbon type gauge ('Empty - 1/4 - 1/2 - 3/4 - Full'). The tank is located in the fwd end of the port sail locked partially recessed fwd under the counter area just aft of the galley sink.Paul Hierstein wrote: “ . . what the factory original fuel capacity was . . “

My 1983 CD30 Cutter is listed in the owners manual as having a 25 gallon fuel tank. That's about right as I recall from the few times I have actually filled her up. BTW I motored about 250-275 miles at high rpm's (6 knots boat speed) on a trip last fall and put about 18 gallons back in when I returned, roughly 0.4 gal/hr. At lower rpm's and about 5 knt. boat speed, fuel consumption should improve considerably. We were in the ICW and had 50-60 miles between ports, so had to motor fast to get there by dark.
The additional deck fill sounds like something someone added on, probably when they put in the existing tank. The original fuel capacity of 25 gal. is plenty.

Twin fuel tanks
Paul,
Iolanthe, my 1977 Cape Dory 30 ketch with the Yanmar YSB 12 engine has two fuel tanks. The tanks appear to be original and I have seen this arrangement on another 30. The tanks are iron and are in the cockpit lockers, port and starboard. I estimate they are about 15 gallons each. There are iron tabs welded to the tanks that are glassed into the hull. There are fills for each tank on both sides outboard of the coamings (chrome bezel labelled "diesel"). There is a selector valve in the cockpit just below the panel for the engine (port side). Iolanthe's fuel consumption is between one to two quarts per hour. This fuel capacity gives Iolanthe a substantial range under power. However it is a mixed blessing. In my useage of the boat, she gets fueled once every two or three years. To keep the tanks clean, I have to pump out the fuel periodically and burn it in the furnace at home to keep the tanks clean and the fuel fresh.
I witnessed the tanks of another 30 being replaced at the Yanmar dealer in Newport RI(same arrangement as mine). I can attest that the tanks are too big to fit through the cockpit locker opening. They were definitely installed before the deck was put on. This dealer sawed the cockpit opening to get the tanks out (ouch). If there are any specific questions that I can answer about this arrangement, please ask.

You have a very interesting fuel arrangement. Cape Dory must have had a 'cruising option' or modification of some sort available.
Did 'Iolanthe' have any other long-range type options?

Long range features
Hi Leo,
I do not know if other CD-30's are the same, but Iolanthe came with a lot of water capacity as well as the twin fuel tanks. She came with three (approx 25 gallon) water tanks. The water is stored under each setee, port and starboard, and under the v berth. This arrngement looks original to me (conformal Kracor tanks). I always assumed that all of the 30's of this vintage were the same. The longer you live, the more you learn!

Re: Long range features
Hi Joe,
‘Heather Ann’ also initially had three water tanks. Under each settee, is a 15 gal PW Tank and the v berth had a 24 gal. PW tank, which was converted to a holding tank (original sold as a Great Lakes boat.) All also are conformal Kracor tanks. The later 30's (not sure what year) had a 30 gal. PW tank under each settee (!!) with the v-berth used as a holding tank. When aboard Hanalei (Capt. Commanding, #1, Nautical Traditions, etc., etc) I noted his settees were slightly higher than 'Heather Ann' - guess to get the volume for 30 gal.
See Post below - another 77 ketch w/ 2 fuel takes. Like ya’ say, we keep learning. Thanks for the daily education lesson
