Hello all, just returned from a lovely extended weekend in the Apostle Islands (and added another boat to the fleet) and now have the following question. I have a Henderson footpump that I'd like to install in a Current Designs GTS. The bulkhead in the CD boats is plastic and I am not sure if it is strong enough for the pump. If it is someone let me know. Otherwise I am going to have to reinforce it somehow. Any ideas or tips? Adding a layer of glass, a piece of wood or something? One other question. Any tips (psychological help welcomed as well) for drilling the large hole in the deck. Best bit for this, speed, should I tape to keep fracturing down? Thanks! -Patrick PS My newly added fiberglass keel-strip is holding up wonderfully. Lots of dragging on the beach without a problem. It looks like my worries about adhesion to the gel coat are thus far moot. *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced/forwarded outside PaddleWise without author's permission Submissions: PaddleWise_at_PaddleWise.net Subscriptions: PaddleWise-request_at_PaddleWise.net Website: http://www.paddlewise.net/ ***************************************************************************

Patrick, I have a Solstice GT. I haven't installed a foot pump but I've been considering it. When I looked at my forward bulkhead, it appeared much too thin to mount a pump without reinforcement. I wouldn't want to be pumping during an adrenaline rush and put my foot through the bulkhead. I haven't thought out the method of reinforcement yet, but I imagine it would take the form of spreading the load over as much of the bulkhead area as possible. I'd be interested in hearing (seeing) the solution you come up with.

The bulkhead is ABS plastic and is reasonably strong, though too flexible to be used to mount a pump in the middle. The glue that holds it is tough - I know, I've ripped out the bulkhead in my GTH and replaced it with okoume/fiberglass. It was a lot of work to remove! So, you could probably put a piece of epoxy- or varnish-covered (for waterproofing) plywood against the bulkhead on the cockpit side and use it to stiffen the bulkhead. I don't think the glue would let go - YMMV. Fiberglass covered plywood would be stiffer for a given thickness. Bolt the pump mount right through both layers.

What is the best (or easiest) way to figure out the dimensions of the bulkhead? I was thinking bending a piece of bailing wire and going of that. Well, considering the hatch it would probably have to be four pieces of wire. What solutions have people used? -Patrick *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced/forwarded outside PaddleWise without author's permission Submissions: PaddleWise_at_PaddleWise.net Subscriptions: PaddleWise-request_at_PaddleWise.net Website: http://www.paddlewise.net/ ***************************************************************************
Patrick; I have taken the shape of the front bulkhead by pushing in a rough cardboard template, and refining that until accurate. I then cut a 4mm ply piece, fitted 20mm blue closed cell foam behind it on the bulkhead side, and bolted the foot pump to that. After attaching the inlet and outlet hoses, no fastening is needed for the "false bulkhead" on which the pump is mounted. Seems to spread the load OK.

Trying to cover as much as possible. once you are close, take a drawing compass set to some convenient dimension and scribe along the inside of the hull, making a reduced copy onto the cardboard. Once you pull the cardboard out of the boat you can, reverse the compass and follow your traced line to make a full sized template. Chances are that a full sized piece will still require fitting and may even need to be put into pieces to fit around other obstactes. (foot brace tracks, etc) I'm sure other's amoung us have even better ways / more interesting tricks.

That't the side you want to mount to, right? So you don't have to go throught body contortions, you might try the following: Set up two step ladders and tie them so they wont fall over. Install you boat on this ladder set-up so that it is horizontal, cockpit inverted and cockpit rim at about shoulder height. Tie the boat to the ladders so it doesn't "travel". Adjust up or down so you can "comfortably" reach to the bulkhead. Now the bailing wire should work. Actually, bailing wire may be too stiff. Copper wire might be a better choice. Good luck, Bill Leonhardt *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced/forwarded outside PaddleWise without author's permission Submissions: PaddleWise_at_PaddleWise.net Subscriptions: PaddleWise-request_at_PaddleWise.net Website: http://www.paddlewise.net/ ***************************************************************************
For creating a template of the front bulkhead - I agree that it's **very** much easier to do this through the cockpit, and with the boat inverted at approximately shoulder height. Often it's possible to invert the boat easily by hanging it in your cellar, in your garage, etc.... RE: the bailing wire....(<Now the bailing wire should work.>) There's an inexpensive, neat tool readily available from art supply houses, and also from Staples, Office Depot, etc. It's called a "draftsman's curve". It's a malleable rectangle about an inch in width and from12 to 18 inches in length. It can be bent around a curve or an angle and then it will hold that shape fairly well, for transfer to a cardboard or paper pattern. OTOH - my own limited experience in making bulkheads is that it's just as easy to tape together several pieces of cardboard, making a rough pattern, and then transfer that (slightly *larger* than you think you'll want) to a second piece of cardboard, and then whittle that rough pattern down with a utility knife. You can get a very accurate pattern that way in just a few minutes' time.

Cut a piece of cardboard slightly smaller than the rough shape. Tape smaller bits of cardboard around the perimeter to fill in the gaps around the edges. Cut a piece of cardboard slightly larger than the rough shape. Slide it in as far as possible--trim off where it's tight, and refit it. Trim the new tight spot until you're against the original bulkhead. Lying a the body of a pencil flat against the hull or deck and scribing around the template will give you a line an even 1/8" all the way around. Fit your plywood bulkhead to the cockpit side of the original plastic bulkhead--that's the size you're going to mount it to anyway. If you can't get a wire or cardboard template out, you're certainly not going to be able to get a plywood bulkhead in! >I think that is what I'll end up doing.
