    Mr Scott you going to beam up this Delta III to the down under Enterprise? Don't think the Delta has photon torpedoes tho.

    Thanks,
    Yeah, that's plenty of speed controller. Way more capacity than the three motors -- stalled -- can pull. And you got the room for the big toggle, so, yeah, use that.

My best guess is that this weight needs to be doubled to calculate the water needed for displacement, or 28.2 oz of water minimum. I calculate a 2.5" water cylinder would need to be 9.9" long or about the same as the Gato sub-driver. A 3" cylinder needs to be 6.9" long. This might be minimal and a little extra volume would not hurt
    I was thinking a GATO SD with FOXTROT motor-bulkhead as well. Can do.

    Dave, Bob has the only Golf boat that I made from my molds. Bob needs to weigh the boat. I have the Golf molds here all boxed up and ready to ship to Don just so you guys know. I am sending 3 completed sails and 3 complete appendage resin sets with the molds so the only thing Don has to do is make 3 hulls to make 3 kits.

    It will be just the 3 motor bulkhead I think. Surprised you got that to fit in a 2.5" cyl. I am using a easy driver in the Delta and pass thru wires to a separate dive cylinder for diving. Think I will have to do that here too, Tim's glass is pretty thick so I am not sure there will be enough vol. in a 2.5" cyl. to make it work right. Could make a bulkhead that steps to a 3" cyl. Will weigh the sub tonite.

    OK, Tim. I assume you have a hull and sail there. Would you weight the upper hull and sail for me (and estimate what the percentage of below-waterline structure is to total upper hull structure). With that dope I can estimate the amount of ballast water needed to drag this sucker down into the deep-blue-sea.

    It's going to be a 2.5" cylinder, as that's what the 3-motor bulkhead is designed for.

    Dave the Golf hull thickness is about the same as my other boats. Around .090 thick. Used epoxy resin so it is a little porky. Whole sail is free flooding. Maybe Bob could weigh the boat and see if that helps you out.
    Good idea, the specific gravity of GRP is a bit over 1. Does the hull separate at the waterline -- that would be perfect. If that's the case, weigh the upper hull and sail and I can take it from there. I would fudge-factor in another 15% to the ballast tank, just to be sure (better too much ballast water, then too little).

    My email address is: schutzen2@gmail.com if you would like to reach me that way.

    Thanks for asking, Bob. I sell exclusively through Nautilus Drydocks. Contact Bob Martin.

    Yes, I have plenty of the three-motor bulkheads. Do you want a complete SD (static type) for the 1/72 FOXTROT or do you just want the assembled and tested motor-bulkhead?

    Caution: Though the GULF was of similar hull form to the FOXTROT, I would imagine that the sail would displace about three-times the water as the FOXTROT sail (assuming same gauge lay-up). Rick Polumbo, originator of the sail and hull GRP parts for the FOXTROT, laid up aircraft gauge GRP parts thine ... and I mean 'thin' with a capital T.

    Further, I don't know how thick the GULF hull and sail parts are, so I can't work out the above waterline displacement, i.e. I don't know how much floodable volume to work into a SD for that boat.

    I have been finding killer plans on feebay. Also have gotten some real good plans from Don.
