Dave, Thank you for the quick reply and info. I must say the response from all hands was impressive.

(and other readers): as Skip and Tod have stated the foam is only to keep the boat floating at the deck level if you REALLY swamp the boat. Phil's inflatable bag system also works. this is what he installed on his Sage 17. Jerry has told me on his M15 he would fill the forward section of the v-berth with water jugs, not foam, for extended cruising in the Sea of Cortez. as Tom has stated as the wind increases be sure to put the drop hatches in place to keep most of the water out if you get pooped or knocked down. the M15 will self right if knocked down ... this ability was tested a few times with M15s during HPCC 2012. Tom also noted, correctly, that there is no need to 'over fill' the boat with foam. the amount that Jerry installed 'stock' is adequate to keep the boat afloat, at deck level, if 100% swamped. :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: M17 #375 SWEET PEA - www.m17-375.webs.com :: Sage Marine - www.sagemarine.com --- On Tue, 2/28/12, Robert Macomber <macomber@robertmacomber.com> wrote:
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? Bob Macomber NANCY ANN M-15 #195 Matlacha Island Florida

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
