Spare Parts for Freeman Marine Model 30 Round Deck Hatches (30" / 762 mm)

Welcome to Bövik Marin AB – authorized European supplier of genuine factory replacement parts for Freeman Marine Model 30 round cast deck hatches. Offering a massive 30-inch (762 mm) clear opening, Model 30 is Freeman's largest round hatch, engineered for heavy machinery access trunks, equipment rigging, crane access, and personnel transit across commercial workboats, oceanographic research vessels, tugs, and work barges.

Due to the extensive diameter and immense sealing loads required to ensure 100% watertight integrity around the 762 mm coaming rim, Model 30 (Series 2415 & 2452) is equipped from the factory with Freeman's reinforced 316 stainless steel dogging mechanism. Four heavy-duty 15-inch stainless dog arms are driven synchronously by a solid stainless cam hub to deliver uncompromising perimeter compression in under a quarter-turn.

Below you will find all genuine mechanical and elastomeric components required for scheduled maintenance, survey overhauls, and complete mechanism rebuilds for Model 30:

Technical Guide: Service and Mechanism Maintenance for Freeman Model 30

The Freeman Model 30 (Series 2415 & 2452) is engineered for the heaviest commercial duty. Operating a deck closure across a 762 mm span imposes immense torsional and bending moments on the mechanical linkage, which is why Freeman equips Model 30 with solid 316 stainless steel components to prevent mechanical deflection and cyclic fatigue failure.

1. Reinforced 316 Stainless Steel Dogging System

15.00-Inch 316 Stainless Dog Arms (Part no. 0212-2012): Model 30 utilizes four 15.00-inch dog arms (381 mm) investment-cast in solid AISI 316 stainless steel. These heavy-duty arms resist high bending loads as the gasket is compressed against the coaming bed. Ensure during servicing that nylon cam buttons (Part no. 0621-2004) are fitted and undamaged.
Solid 316 Stainless 4-Hole Cam Hub (Part no. 0212-2015): The central hub is precision-cast in stainless steel to transmit operating torque without rotational distortion. Periodically lubricate the hub cam tracks with high-adhesion waterproof marine grease (e.g., Vickers Biogrease EP2) to ensure smooth, low-effort quarter-turn actuation.

2. Compression Gasket Integrity

Smooth Spigot Coaming Design: Model 30 is built around Freeman's compression sealing principle featuring a raised solid spigot without an outer collection trough, enabling fast deck washdown without drain plumbing.
Gasket Renewal: Clean the cover channel thoroughly of dried salt crust and old adhesive before seating the new gasket. Seat the continuous molded ring evenly into the channel without stretching the elastomer. Apply marine silicone spray prior to winter operations to prevent freeze-adhesion.

3. Center Bushing & Spindle Sealing

Model 30 utilizes Freeman's heavy-duty Universal Center Bushing Overhaul Kit (Part no. 0031-2204). At any sign of moisture seepage beneath the deck handle or if axial play develops, renew the bushing assembly complete with fresh dual O-rings and stainless roll pin.
