I better get busy. Sailing season starts in a month or so!!!

I drink box wine, and if you remove the plastic bags from the boxes, you can blow them up and they work well for floatation for a season (heck, they could last forever, I don't know...). Check them to see if they loose any volume, but I'd be surprised if they do. Contain them in a big plastic bag and Voilà, super floatation. t On Tue, Feb 28, 2012 at 2:57 PM, Joe Murphy <seagray@embarqmail.com> wrote:
Where did you find your inflatable bags? I was thinking of using inflatable inner tubes like you'd find at beach stores. One at the stern under the cockpit and one forward under the V berth but I'm not sure how big I need to get them to keep afloat. So, does anyone have any idea how many cubic feet is needed to keep a swamped M17 afloat?

I have gone to inflatable bags. See Aire inflatables for the replacement bladders for the kayaks, cats and rafts.

Dave,
What would happen if you take all the styrofoam out of the forepeak and under the cockpit. Would it affect the boat's sailing or stability? Or is it's purpose only in case of capsize or swamping, to keep the boat afloat?

jerry's M15s had a couple of large blocks of foam that sit in the 'box' formed between the bulkheads and stringers that support the cockpit floor (ie, foam is a large rectangle under the cockpit floor). no foam is in the port and starboard cockpit locker spaces.
the forward v-berth space is filled with 'artfully cut' pieces of foam that is shoved to fit and fill 90% of the forward 2/3rd of the v-berth. the hatch (jerry calls it a 'bin cover') that provides access into the forward section of the v-berth should be screwed shut so the forward foam can't get out if the boat is swamped.
the lockers port and starboard of the potti space are for storage, not foam.
'spray in' foam may be the only option (besides pool noodles, or flotation bags) to correct any missing foam issue under the cockpit. i recommend a non-spray solution to the forward portion of the v-berth.
the foam used by jerry was expanded polystyrene (EPS). if you are near golden, CO, i can provide some for a M15 revitalization project. (i have EPS in stock for the Sage 17 positive flotation option).

I'm still working on my 15ft Monty and noticed that the old styrofoam is breaking up . That's in both the front and back areas , at the back there was just two small blocks about 8x10 inch by 1ft . I'm thinking of either filling the areas with some of the building foam in aerosol cans , or using sailing dinghy buoyancy bags . Anyone done either or have any ideas why one shouldn't do either Thanks in advance for any comments KLaas
