[Public-List] Cockpit floor hatch?

Fri May 29 08:36:52 PDT 2015

ok here is the info from Cookin and Gillilajie (or something like that)
I just ordered my hatch from Hamilton Marine. I called them to ask which was the best one and they said the Bowmar had was better. They are the ONLY ones that have this hatch. There was NO advantage (other than a slight savings in shipping cost) to order multiple hatches, so everyone is ordering their own...especially since I didn’t want to run up a $1,200 charge on my credit card. So here’s is what to order... https://store.hamiltonmarine.com 
| HATCH BOMAR ALUM 10" RND DECK HATCH W/ T HANDLE 104629 @ $ 299.99orHATCH BOMAR ALUM 10" RND DECK HATCH W/T-HNDL WHT 104630 @ 339.99 (If you want it white powder coated) The white ones are not in stock but they have 3 on order from Bowmar. I ordered white because Trish likes to be bare foot on the boat and the old hatch gets too hot to stand on. |

A cockpit hatch is a very good idea. It allows vastly improved access to the rear of the engine area and stuffing boxes.  Bomar makes several types of offshore aluminum flush deck hatches that will fit.  There may be a couple of photos on the A30 web site showing these installations.

Dolce had a completely separated cockpit floor when I purchased the boat, so I replaced cut it out with a skill saw and replaced it with a new fiberglass and foam core cockpit floor with a 20" by 24" built in hatch opening.  Anything smaller and you will have trouble reaching down to the engine and drive line.  All built with 1/2" foam core and glassed over top and bottom - hatch combinings are 1 1/2" or there about  and the hatch itself about 3/4" thick.  Easily stronger than my old commercial fishing boat deck and hatches in Alaska and the combing and reinforcement under deck are significantly stronger than the rest of the Alberg construction- rivaling maybe the layup of the hull.  Also I put in rubber foam insulating strips to make it watertight, and a dog forward and pin aft to lock it down for ocean service.

also added battery boxes under the cockpit floor, and relocated both batteries to get them out of the bilge, and above the water line!  What A terrible place for batteries to begin with.  

Highly recommend going this route If you want to increase access to the rear of the engine space. Not that hard to do to cut out the forward part of cockpit floor and prefab a hatch opening, then glass everything back together.  Or go with a Bomar style hatch.

Whatever you do  stay away from yachtie 'offshore lazarette hatches'.  They are not designed to be jumped on continuously and will leak and break at some point.

Seems to be primarily for reaching the prop shaft packing. It helps, but it is still not easy to adjust. In any case, I'd strongly recommend a "structural" frame hatch with a metal or very strong top surface. I have had some delamination of that floor, so I constructed an oak strip false floor many tears ago which transfers all the loading to the edges, anyway. I'd be very cautious about weakening the floor with a larger hatch.
