About the mast, roof area.... I read there are four small roof vents in the main cabin. Although I welcome roof vents in this hot area, it would seem the roof vents and the smoke stack might preclude strapping a dinghy up there.... How much flat roof is there on top?
Are the mast and boom pictured functional? Could one use them to load crab pots, or even a dinghy onto the boat or roof? Any possible function as a stabilizing sail? ...or too far forward and high?
any info would be good on this... John
Given the dimensions and layout of the boat the best place for the dinghy is on the swim step and not on the cabin top. As always I appreciate observations from all viewpoints but there is a lot to recommend the swim step location on this boat.
Anybody that's tried to lauch and retrive a dinghy from a cabin top of a relatively tall boat will appreciate just how much motion there is up there with any wave action. Even with a mast and boom to help things get a bit interesting with a wildy swinging dinghy off to the side of the mother ship.
Adding more mass at the height of the cabin top also adds to the roll moment and adds windage.
It is much safer and more comfortable for folks to work on a flat deck at or near the waterline. It's doubtful that smaller members of the crew could even launch and/or retrieve a cabin top mounted dinghy yet even the smallest folks can safely lower and raise a transom mounted dinghy safely.
A dinghy attached to the swim step on brackets (when lowered) is also a safer vessel to enter into and exit from as it isn't able to slide around as a dinghy on the loose is.
Finally, a dinghy attached to the swim step gives one a better shot at positioning an outboard on the transom without going for an unintended swim (or for that matter having the outboard make a plunge to the bottom).
That said without the optional mast and perhaps by deleting the smokestack there would most likely be room on the cabin top for a small dinghy; especially if a support bar is fashioned for the after end to raise it to the same level as the forward part of the house.
The 'boom' on the mast is not functional; it's simply an aesthetic treatment and is fixed in place at the proper juanty angle.
Best use for a stabilizing sail is typically in rough conditions with the wind blowing (that's obvious!). In those conditions even small sail areas generate a lot of pressure and the mast and rigging must be able to take those loads and transfer them to the hull which isn't the case here.
