Hi guys , like to add my two cents to the core discussion. My 1975 M17 # 79 has half round ribs under the fore deck no core . If the deck had been cored with balsa she would have been in the land fill 20+ yrs ago hooray for solid decks and hulls . The only weak point on the boat as built was / is iron ballast Sent from my Samsung Galaxy smartphone. -------- Original message --------From: Dave Scobie <scoobscobie@gmail.com> Date: 10/24/21 6:33 PM (GMT-06:00) To: For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Subject: M_Boats: Re: Anchoring m 15 BLOG post I linked before has details.
