Subject: Removing the hatch on a Sanderling
I'm in the process of refinishing the bright work on my '79 Sanderling (449). I'd like to remove the cabin hatch and work on it at my workbench. Can anyone tell me how it is held in the sliding track and the steps to removing it? I'm hoping removing and reattaching it is a pretty simple operation. Thanks. Brenton

Subject: Repower
I am trying to repower my HA-18 from my Johnson 2-stroke in the well. I want to put in a 2 cyl. Diesel inboard with a folding prop. Does anyone have a HA-18 with an inboard engine? Any and all help would be great. Thank you Mark Haverland

Subject: Herreshoff 18 mast tabernacle
I recently built a mast tablernacle for my 73-built Herreshoff America 18 which I bought in May. I am pleased how it came out. I ordered a 4' section of 5" Schedule 40 Marine grade aluminum pipe online and used it to sleeve the original mast section. I used only hand tools and fasteners. No welding was required. The design is based on Platero ( which then modified to minimize the amount of bending required. Here are a few photos of the mast step on my boat, Peregrine.

Subject: Herreshoff 18 Catboat 1977 - Paint Color Match?
Hi - I recently bought a sweet Sqaudron Yachts 1977 Herreshoff 18 Catboat. There is some damage to the toerail that I have repaired and am trying to match the faded and yellowed white color. There are two Interlux paint colors that look close: Oyster white and arctic white - but alas the real color is somewhere in between. Has someone out there found a good color match for patching the faded white on a herreshoff of this vintage and make? Thanks for any advice! Peter

Subject: mystic 20 hull reinforcement
I recently purchased a mystic 20 (Hull #5) and I noticed that there is quite a bit of flex in the aft quarter panals, which are fairly flat (see stress fractures and slight bulkhead separation). I would like to stiffen these areas with either more layers of glass or by adding some stringers. Has anyone tried this on a mystic 20? What did you do, and did it work? Thanks, John Beck, Topsfield, MA

Subject: Centerboard
Me again, designing a 17 ft catboat sim. to the Marshall 18. Question -- do I need a steel centerboard for stability, or is the boat's beam sufficient. I would really like to make a cored fiberglass board to minimize the weight. Will it work? Thanks, Ted

I am in the process of designing a catboat and intend to use a Marshall Sandpiper 15 rig. Anyone tell me how high the mast is above the water? I have a power line to get under. Thanks, Ted

Subject: Cockpit sole replacement in an 18' Marshall Sanderling
Does anyone have pictures of what the structure looks like beneath the "floor" in the cockpit of a Marshall 18' Sanderling? If so, I would really like to have a copy! Also, any tips on replacing the cockpit "floor" would be greatly appreciated. Thank you, Bill Van Winkle
