Sales Brochure

Custom quality! For a reasonable price, the Bristol-27 provides a quality hull filled with excellent features and workmanship. The proven reliability of both designer and builder makes it a lasting value. She’s roomy! She’s fast! She’s a good heavy weather performer! She’s a boat we are proud to place against any kind of competition. We feel she’s an “inside and out” bargain. Pick the version that best suits your needs … and compare! Hand lay up construction and full length keel with attached rudder provides strength and sailing stability.

Fall in love! The best way to judge a boat is to sail it, to live in it, to own it over a period of time. This isn’t always possible to do before you buy, but you certainly can ask other owners what they think. Ask them what they think of the Bristol styling inside. Ask them about the quality of materials and workmanship. Maybe you could turn on the charm and ask them for a ride.

If you fall in love with it … great! You’re on your way to sailing satisfaction!  Note: inboard power available. Check the long list of optional equipment and tailor this mini-yacht to taste.

Questions

+ Where is the center of gravity in the Bristol 27?
-> 1/30/11 – I would really like to know this! However, I think this is a difficult thing to calculate. I have a general idea, which is that is just behind the mast-step kind of where the first bulkhead is in the salon. I think that in the long term, I should get a better specific understanding of this location, however at this time I will leave this question be.

 


+ Where is the hull number on a Bristol 27?
-> 6/26/13 – If you want to find your hull number and year built, you might be able to check the hull topsides near the transom.  I found mine far aft on the starboard side.  Below are some photos of mine:

Here's the hull number itself. In plain English, my guess it reads 'Bristol Yachts 27. Hull #370. Built on (?) 09/1975

  1. Just purchased 27′ Cruising Model 9-15-11. It is moored in Florida where I plan to cruise here this winter. Anyone know the bridge clearance heigth of the mast?

    • Hi Ed – good question. I don’t have a definite answer for you, but I believe the mast to be around 37′ + freeboard (~4′?). I would think crossing under a 45 foot bridge or above you should be fine, but if you end up measuring this yourself please let me know and I can add this data to the site.

      • I just bought a 1969 Bristol 27 Weekender. Hull number 50 (it’s on the sail, anyway). I can’t find a serial number or other manufacturer’s id plate anywhere aboard. I took out the outboard engine and fuel tanks, and stuck my head in the lazarette, and still nothing. Hints?

        By the way: an old Boy Scout trick is to step back with a pencil or ruler held at arm’s length, project the height of the mast to a length on the pencil, and rotate that distance to a horizontal surface the same distance away as the boat, and have someone place markers. Then measure along the ground between the markers. Much easier than climbing the mast… or taking it down.

        • Isn’t the SN on the title? I think ’69 was before the SN was required by the USCG. I remember reading that the pearson brothers were bad about that…

      • I have a 1966 and in the 33 years I have owned her I STILL haven’t found a hull number 🙂 I was told to use the sail number (#82) and that has served me well over all these years.

        • I was told that the numbers were on the port side all the way astern. On the top edge. That is when I remembered it needing extra sanding there as I prepped it for paint. It’s #42B

    • The Mast on the Bristol 27 is 31′ 9″ and it sits about 4′ off the water. I just got mine under a 36 foot bridge clearance. I have a 2 foot antenna and just touched (that will make you pucker). I hope this helps. I like the boy scout trick.

      • Hi, sorry for the delayed response, yes they are still available. If you send me your email address I will send you pictures. They are brand new, never been used and have been stored on shore in conditioned space. My Bristol got severely damaged in a storm and I never got a chance to use them.

  5. I purchased a 1965 Bristol 27 (no hull number that I can find). She is beautiful but requires a lot of work, as she was abused and neglected, so I am in the process of refurbishment. I am looking for an electrical wiring schematic. Does anyone know if one might exist somewhere?

    Thank you,

  6. Thanks for both your comments Dave and Dennis.

    @ Dave – Not sure what book you might be looking for, but here are a couple good sources for deck recores:

    * http://www.lackeysailing.com/angelina/march11/31411.htm (press ‘next’ at the bottom of each page to see the repair progress)
    * http://www.triton381.com/projects/restoration/recore.html

    @ Dennis – I’m sorry, not aware of any wiring schematics at this time. I would be interested to see one as well, but if you are doing a big rebuild, it might be worth planning out a whole new wiring set-up. I suggest this, because at least in my B27, the wires ran between the deck and headliner and were inaccessible, plus you may have different wiring needs than the original set-up.

    Do you happen to know where the first picture of the B27 lying on its side was taken?

  9. Just purchased #345 on Lake Ontario, with what appears to be an original Bukh 10 hp diesel. Anyone know what the gearing ratio is on this? Looking to re-prop her.

    • Hi Mike,

      Thank you for your comment. I’m not sure if the other Bristol 27 owners monitor this page as much. Good news is, I think I can give you a good contact.

      When I was looking at Beta motors, they work with a preferred propeller company that offered me assistance when I was looking for a propeller. If you gave them a call, I’m sure they’d be able to advise. Here’s their contact information:
