This rescue boat is made of flame retardant glass fiber,inner and outer hull are filled with polyurethane foam,which could provide enough buoyant for the rescue boat.
The plans for this model are loosely drawn after the Helen Euphane, a 114 foot 293 ton steam powered example of the type.
It's hard to see from this angle but the stringer laying on the building board is scribed in profile to establish the deck sheer.
The Helen, as typical of such boats, carried two 32' purse boats on davits at the stern. Both sides of the rescue boat is equipped with rigid handrails for occuppant coming and down. The fish is use in animal feeds, fertilizer, paint, cosmetics, and its oil has commercial value, It's not a human food fish. She was built in 1902, and served temporarily in both world wars in the Coast Guard, as a minesweeper and patrol boat. These were used to set the seine, draw the purse closed, and assist in hauling the catch. The Hartman kit you refer to is the one in the bottom 3 photos I posted, and yes, it's too pricey for us mere common folk.

Auto-drainage system could ensure that the seawater into the cabin be quickly discharged.The boat is installed with a self-righting air box,which could make the boat self righting while capsized. The atlantic seaboard is the largest fishery and a huge fleet of these boats, all architercturally similar, is maintained there. The last history I have of her is from the 50s, at which time she was still working the fishery. I grew up near Sandy Hook New Jersey, and if we stayed at the beach late enough we often got to see the menhaden fleet coming back in from the ocean. I have a bunch of tugboat models including a Hartman tug that's been a work in progress for about 8 years now. Some souces call the menhaden catch the most important commercial catch in American waters. The simulated caulking is done by running a #2 pencil along the edges of the plank before laying it. The photos are poor quality but they give some idea, especially of the purse boats hanging from their davits. I got tired of paying the big bucks for one ounce bottles of Testor's and did an experiment.

I use the premium grade of Titebond, not because it's that much better than other PVA glues, but because the clamp time is half that of the others. I researched for the most heavily pigmented house paint available in this part of the world.
I build in wood and plastic, and have a Model Shipways Rattlesnake on the bench right now about 70% done. I bought quarts of their best premium exterior acryllic (about $18 per quart) in the 2 colors I'm using.
A lot of experimenting and failing finally produced the formula: one to one paint to water!!
I've seen you on one of the wooden boat forums that I go to (I pretty much frequent them all).
