    where to put ports on a Phantom?

    At the risk of encouraging thread drift, here are some Portsmouth D-PN numbers. As Alan notes, Portsmouth numbers are used to handicap boats: the lower the D-PN the faster the boat (note that D-PNs are sometimes revised).

    Questions on buying a boat and light repairs

    An impact driver probably won't work for this job anyway--the deck where the drain plug is located is too flexible and weak to transmit the force of the driver to the plug (the driver might just punch the drain through the deck). Impact drivers work best on stuff mounted in a bench vise or on...

    Two questions (hull layup schedule, deck drain plug)

    Compared with the original construction (polyester with [only] glass mat and roving reinforcement), your layup is super gutsy.

    Sunfish Mast and Boom Specs

    Dear Jotag-- As you will know, Rig-Rite, Inc. (Kenyon Spars) is a well respected and long-time manufacturer of aluminum masts and spars. (website at: Kenyon Spars Main Page ) They specify that "All Sections are extruded of 6061-T6 Aluminum Alloy, unless otherwise noted." Kenyon does sell...

    Two questions (hull layup schedule, deck drain plug)

    Be aware that the expanding foam used to glue the structural foam blocks in place in a Sunfish sometimes expands against the inside of the transom (I have a boat with the stern completely filled with expanding foam). You can carve or punch out a channel through the foam for a transom drain, but...

    Sunfish Mast and Boom Specs

    Jotag-- I know you from the Laser forum and certainly respect your expertise. I have been told Sunfish masts and booms are 6061-T6, but I have never seen a stamped or stickered Sunfish mast or spar which specified alloy/temper, so without real information I am only repeating hearsay. 6063-T5 or...

    Two questions (hull layup schedule, deck drain plug)

    The bailer hole is located in one of the thickest and least flexible areas of the Sunfish hull. If the margin of the bailer hole is properly prepared and the resin is properly mixed it is extremely unlikely that a glass reinforced plug 1 3/8" in diameter could be "popped out". I certainly agree...

    Sunfish Mast and Boom Specs

    They're 6061 alloy, hard anodized. 6061 is one of the most commonly available aluminum alloys. I *believe* both Sunfish masts and spars are T6 heat treated (Laser masts and booms are 6061-T6, that is, 6061 alloy heat treated to T6). Heat treating to T6 is commonly reported to increase 6061's...

    Two questions (hull layup schedule, deck drain plug)

    If you just plug the bailer hole (without beveling, etc) it's easy to undo should the need ever arise. One of the regular posters here has drain plugs in several styles: Drain Plug Assemblies | SailingForums.com Craig's prices are really low, and he's very easy to deal with. Optimist dinghy...

    Two questions (hull layup schedule, deck drain plug)

    Question 1: Having a hole in the bottom of the Sunfish cockpit is quite convenient for draining lake water, rainwater, or wash water when the boat is hauled. If you don't want to mess with the Sunfish bailer and are prepared to empty the cockpit some other way (bail and sponge out the cockpit...
